The Carelon Clinical Appropriateness Guidelines (hereinafter “the Carelon Clinical Appropriateness Guidelines” or the “Guidelines”) are designed to assist providers in making the most appropriate treatment decision for a specific clinical condition for an individual. The Guidelines establish objective and evidence-based criteria for medical necessity determinations, where possible, that can be used in support of the following:

To establish criteria for when services are medically necessary
To assist the practitioner as an educational tool
To encourage standardization of medical practice patterns
To curtail the performance of inappropriate and/or duplicate services
To address patient safety concerns
To enhance the quality of health care
To promote the most efficient and cost-effective use of services

The Carelon guideline development process complies with applicable accreditation and legal standards, including the requirement that the Guidelines be developed with involvement from appropriate providers with current clinical expertise relevant to the Guidelines under review and be based on the most up-to-date clinical principles and best practices. Resources reviewed include widely used treatment guidelines, randomized controlled trials or prospective cohort studies, and large systematic reviews or meta-analyses. Carelon reviews all of its Guidelines at least annually.

Carelon makes its Guidelines publicly available on its website. Copies of the Guidelines are also available upon oral or written request. Additional details, such as summaries of evidence, a list of the sources of evidence, and an explanation of the rationale that supports the adoption of the Guidelines, are included in each guideline document.

Although the Guidelines are publicly available, Carelon considers the Guidelines to be important, proprietary information of Carelon, which cannot be sold, assigned, leased, licensed, reproduced or distributed without the written consent of Carelon.

Carelon applies objective and evidence-based criteria, and takes individual circumstances and the local delivery system into account when determining the medical appropriateness of health care services. The Carelon Guidelines are just guidelines for the provision of specialty health services. These criteria are designed to guide both providers and reviewers to the most appropriate services based on a patient’s unique circumstances. In all cases, clinical judgment consistent with the standards of good medical practice should be used when applying the Guidelines. Guideline determinations are made based on the information provided at the time of the request. It is expected that medical necessity decisions may change as new information is provided or based on unique aspects of the patient’s condition. The treating clinician has final authority and responsibility for treatment decisions regarding the care of the patient and for justifying and demonstrating the existence of medical necessity for the requested service. The Guidelines are not a substitute for the experience and judgment of a physician or other health care professionals. Any clinician seeking to apply or consult the Guidelines is expected to use independent medical judgment in the context of individual clinical circumstances to determine any patient’s care or treatment.

The Guidelines do not address coverage, benefit or other plan specific issues. Applicable federal and state coverage mandates take precedence over these clinical guidelines, and in the case of reviews for Medicare Advantage Plans, the Guidelines are only applied where there are not fully established CMS criteria. If requested by a health plan, Carelon will review requests based on health plan medical policy/guidelines in lieu of the Carelon Guidelines. Pharmaceuticals, radiotracers, or medical devices used in any of the diagnostic or therapeutic interventions listed in the Guidelines must be FDA approved or conditionally approved for the intended use. However, use of an FDA approved or conditionally approved product does not constitute medical necessity or guarantee reimbursement by the respective health plan.

The Guidelines may also be used by the health plan or by Carelon for purposes of provider education, or to review the medical necessity of services by any provider who has been notified of the need for medical necessity review, due to billing practices or claims that are not consistent with other providers in terms of frequency or some other manner.

General Clinical Guideline

Clinical Appropriateness Framework

Critical to any finding of clinical appropriateness under the guidelines for a specific diagnostic or therapeutic intervention are the following elements:

Prior to any intervention, it is essential that the clinician confirm the diagnosis or establish its pretest likelihood based on a complete evaluation of the patient. This includes a history and physical examination and, where applicable, a review of relevant laboratory studies, diagnostic testing, and response to prior therapeutic intervention.
The anticipated benefit of the recommended intervention is likely to outweigh any potential harms, including from delay or decreased access to services that may result (net benefit).
Widely used treatment guidelines and/or current clinical literature and/or standards of medical practice should support that the recommended intervention offers the greatest net benefit among competing alternatives.
There exists a reasonable likelihood that the intervention will change management and/or lead to an improved outcome for the patient.

Providers may be required to submit clinical documentation in support of a request for services. Such documentation must a) accurately reflect the clinical situation at the time of the requested service, and b) sufficiently document the ordering provider’s clinical intent.

If these elements are not established with respect to a given request, the determination of appropriateness will most likely require a peer-to-peer conversation to understand the individual and unique facts that would justify a finding of clinical appropriateness. During the peer-to-peer conversation, factors such as patient acuity and setting of service may also be taken into account to the extent permitted by law.

Simultaneous Ordering of Multiple Diagnostic or Therapeutic Interventions

Requests for multiple diagnostic or therapeutic interventions at the same time will often require a peer-to-peer conversation to understand the individual circumstances that support the medical necessity of performing all interventions simultaneously. This is based on the fact that appropriateness of additional intervention is often dependent on the outcome of the initial intervention.

Additionally, either of the following may apply:

Current literature and/or standards of medical practice support that one of the requested diagnostic or therapeutic interventions is more appropriate in the clinical situation presented; or
One of the diagnostic or therapeutic interventions requested is more likely to improve patient outcomes based on current literature and/or standards of medical practice.

Repeat Diagnostic Intervention

In general, repeated testing of the same anatomic location for the same indication should be limited to evaluation following an intervention, or when there is a change in clinical status such that additional testing is required to determine next steps in management. At times, it may be necessary to repeat a test using different techniques or protocols to clarify a finding or result of the original study.

Repeated testing for the same indication using the same or similar technology may be subject to additional review or require peer-to-peer conversation in the following scenarios:

Repeated diagnostic testing at the same facility due to technical issues
Repeated diagnostic testing requested at a different facility due to provider preference or quality concerns
Repeated diagnostic testing of the same anatomic area based on persistent symptoms with no clinical change, treatment, or intervention since the previous study
Repeated diagnostic testing of the same anatomic area by different providers for the same member over a short period of time

Repeat Therapeutic Intervention

In general, repeated therapeutic intervention in the same anatomic area is considered appropriate when the prior intervention proved effective or beneficial and the expected duration of relief has lapsed. A repeat intervention requested prior to the expected duration of relief is not appropriate unless it can be confirmed that the prior intervention was never administered. Requests for on-going services may depend on completion of previously authorized services in situations where a patient’s response to authorized services is relevant to a determination of clinical appropriateness.

Shoulder Arthroplasty (Total/Partial/Revision Shoulder Replacement)

Description and Scope

Shoulder arthroplasty includes several procedures to replace components of the shoulder joint, in part or in total, with the goal of improving function and reducing pain. Prosthetic replacement of the humeral head and the glenoid (total arthroplasty) is most commonly performed for joint damage due to osteoarthritis. Total shoulder arthroplasty requires an intact medial glenoid to support the glenoid prosthesis.

Shoulder hemiarthroplasty (partial replacement) may be used to address isolated humeral head pathology (avascular necrosis), some fractures, or as an option for rotator cuff tear arthropathy.

Reverse total shoulder arthroplasty is similar to standard arthroplasty in that both components of the joint are replaced but the ball and socket portions of the joint are reversed, allowing the deltoid muscle to assume partial function of the rotator cuff. This procedure is typically utilized when there is concomitant rotator cuff disease.

This guideline addresses shoulder arthroplasty when performed as an elective, non-emergent procedure and not as part of the care of a congenital condition, acute or traumatic event such as fracture (excluding fracture of implant and periprosthetic fracture).

All shoulder arthroplasties are inclusive of the reattachment of any muscles divided for access to the shoulder, accompanying excision of osteophytes, acromioplasty, synovectomy and shoulder arthrotomy with associated removal of debris.

Clinical Indications

The following general requirements apply to all indications except where they differ from the specific requirements. The specific requirements take precedence over any stated general requirement.

General Information

The terms in the section provide operational definitions when they are referenced as requirements in the guideline.

Documentation supporting medical necessity and a clearly stated plan of care should be submitted at the time of the request and must include the following components:

Clinical notes describing symptom duration and severity, specific functional limitations related to symptoms, and type and duration of all therapeutic measures provided. If conservative management is not appropriate, the reason must be clearly documented.

Conservative management¹ must include a combination of strategies to reduce inflammation, alleviate pain, and correct underlying dysfunction, including physical therapy AND at least ONE complementary conservative treatment strategy.

Physical therapy requirement includes ANY of the following:
- Physical therapy rendered by a qualified provider of physical therapy services
- Supervised home treatment program that includes ALL of the following:
  - Participation in a patient-specific or tailored program
  - Initial active instruction by MD/DO/PT with redemonstration of patient ability to perform exercises
  - Compliance (documented or by clinician attestation on follow-up evaluation)
- Exception to the physical therapy requirement in unusual circumstances (for instance, intractable pain so severe that physical therapy is not possible) when clearly documented in the medical record
Complementary conservative treatment requirement includes ANY of the following:
- Anti-inflammatory medications and analgesics²
- Adjunctive medications such as nerve membrane stabilizers or muscle relaxants²
- Intra-articular corticosteroid injection(s)²
- Alternative therapies such as activity modification, and/or a trial period of rest (e.g., from the aggravating/contributing factors), where applicable

¹ Additional condition- or procedure-specific requirements may apply and can be found in the respective sections of the guideline.

² In the absence of contraindications

Clinical reevaluation. In most cases, reevaluation should include a physical examination. Direct contact by other methods, such as telephone communication or electronic messaging, may substitute for in-person evaluation when circumstances preclude an office visit. Clinical reevaluation must be done in reasonable proximity to the anticipated date of service such that the patient’s condition would be unlikely to change by the date of service.

Failure of conservative management requires ALL of the following:

Patient has completed a full course of conservative management (as defined above) for the current episode of care
Worsening of or no significant improvement in signs and/or symptoms upon clinical reevaluation
More invasive forms of therapy are being considered

Documentation of compliance with a plan of therapy that includes elements from these areas is required where conservative management is appropriate.

Reporting symptom severity. Severity of pain and its associated impact on activities of daily living (ADLs) and instrumental ADLs (IADLs) are key factors in determining the need for intervention. For purposes of this guideline, significant pain and functional impairment refer to pain rated at least 3 out of 10 in intensity and associated with inability to perform at least two (2) ADLs and/or IADLs.

Imaging reports obtained within the past 12 months describing the degree of cartilage damage as determined by either or both of the following methods:

X-ray report or provider interpretation of x-rays that utilizes or can be correlated with the Kellgren-Lawrence grading system of osteoarthritis
MRI report from a radiologist that utilizes or can be correlated with the modified Outerbridge or similar classification system related to articular cartilage injury and osteoarthritis

See Appendix for a description of these grading systems.

For x-ray interpretation, the provider shall submit a detailed imaging description that correlates with clinical findings of the requested procedure. In the absence of a detailed description, the provider may submit a report from an independent radiologist. The results of all imaging studies should correlate with the clinical findings in support of the requested procedure.

For advanced imaging (CT, MRI, ultrasound, bone scan), there must be a report from a radiologist that correlates with clinical findings. In the absence of such a report, the summary findings from the radiology report should be included in the clinical records.

Imaging reports should be thorough and describe the presence or absence of subchondral cysts, subchondral sclerosis, periarticular osteophytes, joint subluxation, avascular necrosis, or bone on bone articulations. The degree of joint space narrowing should also be noted.

General Recommendations

Tobacco cessation. Adherence to a tobacco cessation program resulting in abstinence from tobacco for at least 6 weeks prior to surgery is strongly recommended.

Diabetes. It is strongly recommended that a patient with a history of diabetes maintain a hemoglobin A1C of 8% or less prior to any joint replacement surgery.

Body mass index (BMI). It is strongly recommended that a patient with a BMI equal to or greater than 40 attempt weight reduction prior to surgery.

Where there are patient specific modifiable comorbidities that may adversely impact patient reported outcomes or the health status of the patient a shared decision-making process with the patient to discuss these modifiable comorbidities is strongly recommended and should be documented.

Specific Requirements

ALL of the following conditions must be present regardless of indication for which the procedure is being performed:

Codes

The following code list is not meant to be all-inclusive. Authorization requirements will vary by health plan. Please consult the applicable health plan for guidance on specific procedure codes.

Medical necessity reviews are initiated by submitting the correct AMA CPT codes. Specific CPT codes for services should be used when available. The submitted codes must accurately identify the service or procedure to be performed. If no such code exists, contact the health plan directly and report the service or procedure using the appropriate unlisted procedure or Not Otherwise Classified (NOC) code (which often ends in 99). Do not submit a code that is “close to” the procedure performed in lieu of an unlisted code. Correct coding demands that the code reported is appropriate for the service provided (i.e., a code that most accurately represents the service provided), and not a code that is similar but represents another service. (CPT® Assistant, December 2010) Nonspecific or NOC codes may be subject to additional documentation requirements and review.

Hip Arthroplasty (Total/Partial/Revision Hip Replacement, Acetabuloplasty, Resection Arthroplasty)

Description and Scope

Total hip arthroplasty (THA), also referred to as total hip replacement (THR), involves removal of the femoral head and acetabulum and placement of a prosthesis anchored to the bone. Numerous implants composed of various biomaterials have been approved by the U.S. Food and Drug Administration (FDA) for use in hip arthroplasty. The goal of the procedure is long-term pain relief and restoration of function. All arthroplasty and acetabuloplasty/resection arthroplasty procedures are inclusive of synovectomy, removal of osteophytes, removal of loose bodies, manipulation of the hip, and release or repair of structures to gain entrance to the hip joint.

Degenerative joint disease, or osteoarthritis, is the most common condition leading to the need for total hip arthroplasty. Other conditions that may also cause significant hip joint damage include neoplasm, femoral fracture, avascular necrosis (osteonecrosis), inflammatory arthritis (e.g., rheumatoid arthritis) and developmental hip dysplasia.

This guideline addresses hip arthroplasty when performed as an elective, non-emergent procedure and not as part of the care of an acute fracture (excluding fracture of implant and periprosthetic fracture).

Clinical Indications

The following general requirements apply to all indications except where they differ from the specific requirements. The specific requirements take precedence over any stated general requirement.

Hip Arthroscopy

Description and Scope

Hip arthroscopy is most often utilized in diagnosing and treating conditions of the joint space which impede normal function and result in pain and disability. A more recent application of this procedure is treatment of femoroacetabular impingement syndrome (FAIS), a condition of the hip in which the acetabular rim of the pelvis articulates abnormally with the femoral head. Over time, contact may result in damage to joint cartilage, potentially leading to degenerative joint disease. Hip arthroscopy has also been applied to the treatment of symptomatic labral tears not associated with advanced arthritis of the hip joint.

Surgical treatment of FAIS and/or labral tears may involve an open approach, arthroscopic surgery, or a combination of the two. The surgical treatment of FAIS and labral tears is inclusive of the management of any chondral or soft tissue debridement that is done. It is also inclusive of diagnostic hip arthroscopy. FAIS surgery includes the following components: labral repair, acetabuloplasty, and femoroplasty.

This guideline addresses hip arthroscopy when performed as an elective, non-emergent procedure and not as part of the care of an acute fracture. It does not cover labral reconstructions, capsular plications, or endoscopic procedures done outside of the hip capsule.

Clinical Indications

Knee Arthroplasty (Total/Partial/Revision Knee Replacement)

Description and Scope

Knee arthroplasty involves removal of some or all of the diseased articular surfaces of the knee, followed by resurfacing with metal and polyethylene prosthetic components. Numerous implants composed of various biomaterials have been approved by the U.S. Food and Drug Administration (FDA) for use in knee arthroplasty procedures. The goal of the procedure is long-term pain relief and restoration of function.

This guideline addresses total knee arthroplasty (TKA), revision TKA, patellar and patella femoral arthroplasty, and unicompartmental knee arthroplasty (UKA) performed as elective, non-emergent procedures and not as part of the care of a congenital condition, acute or traumatic event such as fracture (excluding periprosthetic fracture).

All knee arthroplasties are inclusive of the reattachment of any muscles divided for access to the knee, accompanying excision of osteophytes, synovectomy and knee arthrotomy with associated removal of debris.

Revision knee arthroplasty is inclusive of the exchange of some or all of the components of a prior knee replacement with permanent replacements. It is not inclusive of exchange of components for visualization or joint access alone.

Clinical Indications

The following general requirements apply to all indications except where they differ from the specific requirements. The specific requirements take precedence over any stated general requirement.

Knee Arthroscopy and Open Procedures

Description and Scope

Knee arthroscopy is a surgical procedure in which a fiberoptic camera is inserted into the knee joint through a small incision. In addition to allowing the surgeon to visualize the joint, arthroscopy may also be utilized for treatment of a variety of conditions involving the joint structures.

This guideline addresses knee arthroscopy when performed as an elective, non-emergent procedure and not as part of the care of an acute fracture.

Articular cartilage lesions in weight-bearing joints often fail to heal spontaneously and may be associated with pain, loss of function, and long-term complications such as osteoarthritis. A number of surgical techniques have been developed to treat these lesions.

Procedures to treat focal articular cartilage defects can be classified as:

Palliative (lavage, chondroplasty)
Reparative (microfracture, abrasion arthroplasty)
Restorative (autologous chondrocyte implantation, osteochondral allograft, or osteochondral autograft)*.

*See Treatment of Osteochondral Defects

Chondroplasty or debridement is a smoothing or shaving of symptomatic partial-thickness cartilage lesions or chondral flaps (unstable mechanical source of pain).

Microfracture involves drilling multiple holes through the subchondral bone to promote bleeding and fibrocartilage growth.

Abrasion arthroplasty involves abrading the subchondral bone to the depth necessary to promote bleeding and fibrocartilage growth.

Both microfracture and abrasion arthroplasty are typically performed on lesions less than 4 cm².

All arthroscopic and open knee procedure codes are inclusive of diagnostic arthroscopy and manipulation under anesthesia.

Meniscal Allograft Transplantation of the Knee

Description

Meniscal allograft transplantation of the knee is a surgical procedure used to restore normal meniscal function by replacing a damaged or absent meniscus with donor cadaver allograft cartilage. The procedure is an option for a subset of patients who have pain or disability attributed to insufficient cushioning and lubrication of the joint.

A significant subset of these patients have undergone one or more procedures to remove portions of the meniscus due to tears or other injury. The goal of the procedure is reduction in pain, prevention of degenerative changes to the cartilage and subchondral bone, and restoration of the mechanical properties of the knee joint.

Clinical Indications

The following general requirements apply to all indications except where they differ from the specific requirements. The specific requirements take precedence over any stated general requirement.

General Information

The terms in the section provide operational definitions when they are referenced as requirements in the guideline.

Documentation supporting medical necessity and a clearly stated plan of care should be submitted at the time of the request and must include the following components:

Operative report of a prior arthroscopic procedure and/or MRI of the knee performed within the past 12 months. The provider shall submit a detailed imaging report that correlates with clinical findings of the requested procedure. In the absence of a detailed report, the provider will be required to submit a report from an independent radiologist. The results of all imaging studies should correlate with the clinical findings in support of the requested procedure.

Physical therapy requirement includes ANY of the following:
- Physical therapy rendered by a qualified provider of physical therapy services
- Supervised home treatment program which includes flexibility and muscle strengthening exercises that includes ALL of the following:
  - Participation in a patient-specific or tailored program
  - Initial active instruction by MD/DO/PT with redemonstration of patient ability to perform exercises
  - Compliance (documented or by clinician attestation on follow-up evaluation)
- Exception to the physical therapy requirement in unusual circumstances (for instance intractable pain so severe that physical therapy is not possible) when clearly documented in the medical record
Complementary conservative treatment requirement includes ANY of the following:
- Anti-inflammatory medications and analgesics²
- Adjunctive medications such as nerve membrane stabilizers or muscle relaxants²
- Intra-articular corticosteroid injection(s)²
- Alternative therapies such as activity modification, and/or a trial period of rest (e.g., from the aggravating/contributing factors), where applicable

¹ Additional condition- or procedure-specific requirements may apply and can be found in the respective sections of the guideline.

² In the absence of contraindications

Failure of conservative management requires ALL of the following:

Patient has completed a full course of conservative management (as defined above) for the current episode of care
Worsening of or no significant improvement in signs and/or symptoms upon clinical reevaluation
More invasive forms of therapy are being considered

Documentation of compliance with a plan of therapy that includes elements from these areas is required where conservative management is appropriate.

Meniscal Allograft Transplantation of the Knee

Meniscal allograft transplantation of the knee is considered medically necessary as a treatment for individuals with significant partial (more than 50%) or complete loss of the meniscus, as documented by previous operative reports, MRI, or diagnostic arthroscopy, when ALL of the following criteria are met:

Age 55 or younger and skeletally mature
Knee pain refractory to conservative treatment
Ligamentous stability either prior to surgery or achieved concurrently with meniscal transplantation
Normal alignment without varus or valgus deformities

Osteochondral Grafts

Description and Scope

Procedures to treat focal articular cartilage defects can be classified as:

Palliative (lavage, chondroplasty)
Reparative (microfracture, abrasion arthroplasty)
Restorative (autologous chondrocyte implantation, osteochondral allograft, or osteochondral autograft)*

The most widely used are bone marrow stimulation techniques to induce an influx of mesenchymal stem cells into the defect.

Chondroplasty or debridement is a smoothing or shaving of symptomatic partial-thickness cartilage lesions or chondral flaps (unstable mechanical source of pain). See knee arthroscopy section.

Microfracture involves drilling multiple holes through the subchondral bone to promote bleeding and fibrocartilage growth. See knee arthroscopy section.

Abrasion arthroplasty involves abrading the subchondral bone to the depth necessary to promote bleeding and fibrocartilage growth. See Knee Arthroscopy section.

Both microfracture and abrasion arthroplasty are typically performed on lesions less than 4 cm².

Other techniques involve transplantation of osteochondral tissue from non-weight bearing sites, autologous chrondrocyte transplant, and use of synthetic bone filler material or scaffolds.

This guideline addresses treatment of osteochondral defects of the knee, ankle, and other joints using the following procedures or devices:

Autologous chondrocyte transplant (ACT)
Minced cartilage repair
Osteochondral allograft
Osteochondral autograft (OATS/mosaicplasty)
Resorbable synthetic bone filler materials
Microfracture

Clinical Indications

The following general requirements apply to all indications except where they differ from the specific requirements. The specific requirements take precedence over any stated general requirement.

Osteochondritis Dissecans (Juvenile and Adult)

Osteochondritis dissecans (OCD) is a distinct condition that develops primarily in children and adolescents. A focal area of ischemia in the bone results in a progressive separation of a small segment of bone and overlying cartilage. OCD affects the medial or lateral femoral condyles (not the patella, femoral trochlea, or tibial plateau) (AAOS AUC). OCD is usually regarded as either juvenile OCD (JOCD) (occurring with an open epiphyseal plate) or adult OCD (AOCD) (after the physis has closed). The etiology of OCD lesions remains unclear and is characterized by an aseptic necrosis in the subchondral bone area. OCD is not associated with acute trauma.

Juvenile OCD

Surgical treatment (e.g., microfracture, pin fixation) is considered medically necessary when BOTH of the following criteria are met:

Failure of 3 months of conservative management (e.g., immobilization, restricted weight-bearing, avoidance of sports activities)
Presence of an unstable lesion (based on advanced imaging or arthroscopic evaluation)

Adult OCD

Surgical treatment (e.g., microfracture, pin fixation, osteochondral graft) is considered medically necessary when BOTH of the following criteria are met:

Failure of 3 months of conservative management (e.g., immobilization, restricted weight-bearing, avoidance of sports activities)
Presence of an unstable lesion (based on advanced imaging or arthroscopic evaluation)

Osteochondral Allograft Transplantation

Cartilaginous defects of the knee

Osteochondral allograft transplantation to treat cartilaginous defects of the knee is considered medically necessary when BOTH of the following criteria are met:

Size of the cartilage defect is greater than or equal to 1.0 cm² in total area, as documented by MRI or arthroscopy
Condition involves a focal, full thickness, (grade III or IV) isolated defect of the weight-bearing surface of the medial or lateral femoral condyles or trochlear region (trochlear groove of the femur)

Cartilaginous defects of the talus

Osteochondral allograft transplantation to treat cartilaginous defects of the talus is considered medically necessary when EITHER of the following criteria are met:

Large (area > 1.0 cm²) or cystic (volume > 3.0 cm³) osteochondral lesions of the talus when autografting would be inadequate due to lesion size, depth, or location
Revision surgery after failed prior marrow stimulation for large (area > 1.0 cm²) or cystic (volume > 3.0 cm³) osteochondral lesions of the talus when autografting would be inadequate due to lesion size, depth, or location

Osteochondral Autograft Transplantation

Cartilaginous defects of the knee

Osteochondral autograft transplantation, either osteochondral autograft transplant (OAT) or autologous mosaicplasty, is considered medically necessary to treat cartilaginous defects of the knee when ALL of the following criteria are met:

Size of the cartilage defect is between 1.0 cm and 2.5 cm² in total area, as documented by MRI or arthroscopy
Condition involves a focal, full thickness, (grade III or IV) isolated defect of the knee involving the weight bearing surface of the medial or lateral femoral condyles or trochlear region (trochlear groove of the femur)
Absence of “kissing” knee lesions (lesion must be single and involve only one side of the joint)

Cartilaginous defects of the talus

Osteochondral autograft transplantation or microfracture, either osteochondral autograft transplant (OAT) or autologous mosaicplasty, is considered medically necessary to treat cartilaginous defects of the talus when EITHER of the following criteria is met:

Large (area > 1.0 cm²) or cystic (volume > 3.0 cm³) osteochondral lesions of the talus
Revision surgery after failed marrow stimulation for osteochondral lesions of the talus

Autologous Chondrocyte Implantation

Cartilaginous defects of the knee/patella

Autologous chondrocyte implantation (ACI) is considered medically necessary to treat cartilaginous defects of the knee/patella when ALL of the following criteria are met:

Primary chondral defect is present or prior surgical procedure failed to correct the defect
Size of the cartilage defect is greater than or equal to 1.5 cm² in total area, as documented by MRI or arthroscopy (defects greater than 15 cm² may require more than one membrane)
Condition involves a focal, full thickness, (grade III or IV) isolated unipolar defect of the knee involving the weight bearing surface of the medial or lateral femoral condyles or patellofemoral region (includes trochlear region, trochlear groove, and patella)
Defect involves only the cartilage and not the subchondral bone. (Exception to this requirement: treatment of osteochondritis dissecans [OCD] associated with a bony defect of 10 mm or less in depth, which has failed prior conservative treatment. OCD lesions associated with a bony lesion greater than 10 mm in depth must also undergo corrective bone grafting).
Documented minimal to absent degenerative changes in the surrounding articular cartilage (Outerbridge grade II or less), and normal-appearing hyaline cartilage surrounding the border of the defect
Normal knee biomechanics or alignment and stability achieved concurrently with autologous chondrocyte implantation (ACI).

Use of decellularized osteochondral allograft plugs (e.g., Chondrofix®) or reduced osteochondral allograft discs (e.g., ProChondrix®, Cartiform®) to repair osteochondral defects of the knee or ankle
Use of autologous chondrocyte implantation (ACI) in joints other than the knee (investigational)
Allografts preserved by nonstandard tissue bank methods (e.g., Missouri Osteochondral Allograft Preservation System)
Use of larger allografts that involve removing and replacing half or more of the articular surfaces of the knee as an alternative to traditional total joint replacement (e.g., hemi condylar or total condylar for degenerative conditions)
