Description and Application of the Guidelines

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. As used by Carelon, the Guidelines establish objective and evidence-based criteria for medical necessity determinations where possible. In the process, multiple functions are accomplished:

  • To establish criteria for when services are medically necessary (i.e., in general, shown to be effective in improving health outcomes and considered the most appropriate level of service)
  • 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 advocate for 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 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. Relevant citations are included in the References section attached to each Guideline. Carelon reviews all of its Guidelines at least annually.

Carelon makes its Guidelines publicly available on its website twenty-four hours a day, seven days a week. Copies of the Carelon Clinical Appropriateness Guidelines are also available upon oral or written request. 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. 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 should outweigh any potential harms that may result (net benefit).
  • Current literature and/or standards of medical practice should support that the recommended intervention offers the greatest net benefit among competing alternatives.
  • Based on the clinical evaluation, current literature, and standards of medical practice, there exists a reasonable likelihood that the intervention will change management and/or lead to an improved outcome for the patient.

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 supersede the requirements set forth above. During the peer-to-peer conversation, factors such as patient acuity and setting of service may also be taken into account.

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.

Small Joint Surgery of the Foot and Ankle

General Requirements and Documentation

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.

These guidelines address foot and ankle procedures when performed on an elective, non-emergent basis and not as part of the care of an acute fracture.

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 management offered by the provider or other health professionals for this condition(s) should include footwear modification and/or padding/accommodative devices (e.g., foot orthosis) AND at least one of the following complementary strategies to reduce inflammation, alleviate pain, and improve function:

  • Activity modification
  • Anti-inflammatory medications and analgesics
  • Corticosteroid injection(s)
  • Debridement of associated hyperkeratotic lesions, such as corns or calluses

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

If conservative management is not appropriate, the medical record must clearly document why such an approach is not reasonable.

Reporting symptom severity. Severity of pain and its impact on function are key factors in determining the need for intervention. For the purposes of this guideline, significant pain and functional impairment refer to pain rated ≥ 4 on the VAS scale and associated with difficulty performing at least 2 impacted daily activities, such as walking and wearing reasonable shoes.

Imaging report. The provider shall submit a detailed imaging report for studies obtained within the past 12 months. In the absence of a detailed report, 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. Where applicable, radiographic imaging must include weight-bearing anterior-posterior and lateral views of the affected foot.

Imaging reports should describe the presence or absence of subchondral cysts, subchondral sclerosis, periarticular osteophytes, joint subluxation, or avascular necrosis. The degree of joint space narrowing should also be noted. Where applicable, the requesting provider should measure and record the key angular deformity indices in the medical record.

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 any 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.

Hallux Rigidus Surgery

Description and Scope

This guideline addresses surgery for hallux rigidus when performed as an elective, non-emergent procedure.

Hallux rigidus is a painful arthritis of the first metatarsophalangeal (MTP) joint, which can cause stiffness and progressive loss of motion. It is the most common arthritic condition of the foot. The first MTP joint develops progressive degenerative changes resulting in pain, inflammation, and limited motion. The condition is more prevalent in females than males and has an average age of onset of about 50 years. Over 95% of patients have it bilaterally and two thirds have a positive family history.

A variety of scales have been used to grade the severity of hallux rigidus, although the scales proposed by Hattrup and Johnson and Coughlin and Shurnas are most common. For the purposes of interpretation of this guideline, either scale can be used (see Table 1) to determine whether hallux rigidus is mild, moderate or severe. Radiographic confirmation of hallux rigidus must include weight-bearing anterior-posterior (ap) and lateral view of the affected foot.

After non-surgical intervention, a variety of surgical interventions are available to treat hallux rigidus. Cheilectomy involves removal of excess osteophytes and is done to alleviate osseous impaction of the proximal phalanx and metatarsal head through debridement of the articulating joints. Arthrodesis is the most common treatment for patients with advanced hallux rigidus but carries additional risks including the potential for loss of foot function and joint motion, diminished gait efficiency, failure of fixation, nonunion, and transfer metatarsalgia. Alternatives include resection arthroplasty. More recently, implant arthroplasty of the first MTP joint has been proposed as an alternative to arthrodesis for more advanced hallux rigidus as a way of restoring joint motion.

Hallux Valgus and Bunionette Surgery

Description and Scope

This guideline addresses surgery for hallux valgus when performed as an elective, non-emergent procedure.

Hallux valgus is a common deformity of the first ray (great toe) characterized by a lateral deviation of the proximal phalanx at the level of the metatarsal joint. It is frequently associated with a concomitant medial (varus) deviation of the first metatarsal. The result is a bony prominence or “bump” on the medial side of the first metatarsophalangeal joint. This is often referred to as a “bunion” and may be associated with soft tissue swelling and pain. In addition, the articular surface of the first metatarsal may have a valgus (lateral) inclination also contributing to the deformity. As the deformity progresses the sesamoid complex will shift laterally aided by the deforming force of the adductor tendon and the lateral capsule tightens while the medial side attenuates. When conservative management fails, the surgical correction of bony and/or soft tissue hallux valgus is often performed, and over 100 different surgical techniques have been described in the literature. Surgical procedures for hallux valgus include simple bunionectomy, various soft tissue procedures, metatarsal and phalangeal osteotomies, resection arthroplasty, and metatarsophalangeal arthrodesis.

Bunionette deformity, also known as Tailor’s bunion, involves the fifth metatarsal head with a painful lateral bony prominence. It is often associated with constrictive footwear causing pain, inflammation, keratosis, and ulceration. When conservative management fails, surgical methods include condylar excision, proximal or distal osteotomies.

For arthrodesis indications, please see the criteria for hallux rigidus.

  • Significant pain and functional impairment and/or presence of a pre-ulcer (e.g., Wagner grade 0-1) that persists after at least 3 months of supervised conservative management or non-healing ulcer attributed to the metatarsal deformity
  • Physical examination or imaging confirmation of an anatomical difference requiring osteotomy

Contraindications

All Osteotomy Procedures
  • Active infection of the joint
  • Active systemic bacteremia
  • Active skin infection
  • Inadequate bone stock for osteotomy or arthrodesis
  • Peripheral vascular disease

Exclusions

  • Surgical intervention solely for the purpose of improved cosmesis

Lesser Toe Deformities

Description and Scope

This guideline addresses surgery for lesser toe deformities when performed as an elective, non-emergent procedure and not as part of the care of an acute fracture.

Deformities of the lesser (two through five) toes are generally known as hammer toe, claw toe, and mallet toe. A related deformity of the great toe is known as a hallux malleus.

Hammer toe is characterized by flexion deformity of the proximal interphalangeal joint of one or more of the lesser four toes. In severe or chronic conditions, it may be associated with either flexion or extension of the distal interphalangeal or hyperextension of the metatarsophalangeal joint. The most commonly affected toe is the second, although multiple toes can be involved. Hammer toes are considered flexible if passively correctable or rigid if not correctable to the neutral position.

Mallet toe is characterized by flexion deformity at the distal interphalangeal joint only.

Claw toe deformity is characterized by flexion deformities of the proximal interphalangeal and distal interphalangeal joints as well as hyperextension at the metatarsophalangeal joint.

The main bony procedures used in the treatment of second hammertoe are excisional arthroplasty and arthrodesis of the proximal interphalangeal joint. Arthrodesis of the proximal interphalangeal joint represents the standard treatment for rigid and structured deformities not suited for manual correction. This procedure is performed by removing the articular surfaces of the proximal and intermediate phalanges. Although many systems such as cannulated screws or absorbable pins have been designed for the fixation of arthrodesis, the K-wire is the most utilized traditional method. Surgical management of lesser toe deformity may also include soft-tissue release, tendon transfer, joint resection, joint fusion, metatarsal shortening, or a combination of procedures.

Ankle Arthritis

Description and Scope

This guideline addresses surgery for ankle osteoarthritis when performed as an elective, non-emergent procedure and not as part of the care of an acute fracture.

Ankle osteoarthritis presents in approximately 1% of the world’s adult population. The primary cause of ankle osteoarthritis is trauma associated with pain, dysfunction, and impaired mobility. Other causes include rheumatic diseases, gout, hemochromatosis, avascular necrosis, hemophilia, and postinfectious conditions. In the early stages, conservative management may decrease pain and preserve function. Ankle arthrodesis or total ankle arthroplasty may be indicated for advanced cases. Ankle arthrodesis was considered the gold standard treatment in patients with end-stage ankle osteoarthritis until the 1970s, when the first total ankle arthroplasty procedures were described. Although gait efficiency is decreased with ankle arthrodesis, most surgeons still consider it as the procedure of choice to alleviate pain in patients with end-stage ankle osteoarthritis.

Ankle arthrodesis is regarded as a reliable treatment for end-stage ankle arthritis because it yields good results with a low complication rate. A commonly reported risk of ankle arthrodesis is adjacent joint degeneration that occurs more frequently in those with arthritis of the ipsilateral hindfoot and midfoot.

Total ankle arthroplasty was first performed in 1970 as an alternative treatment option to ankle arthrodesis—the gold standard at the time for end-stage ankle degenerative joint disease. Initially, total ankle arthroplasty had high rates of subsidence, loosening, and revision. However, with the advances in implant design such as uncemented implants as well as fixed and mobile-bearing surfaces, total ankle arthroplasty has resulted in improved outcomes.

Clinical Indications

Ankle Arthrodesis

Ankle arthrodesis is considered medically necessary in skeletally mature patients when ALL of the following criteria are met:

  • Radiographic confirmation of advanced/end-stage arthritis of the tibiotalar joint
  • Significant pain and functional impairment due to arthritis of the ankle persist after at least 3 months of supervised conservative management
  • Documentation of adequate lower extremity vascular perfusion (e.g., strong, palpable pedal pulses)

Ankle arthrodesis may also be indicated for revision of failed previous reconstructions where sufficient bone stock and soft tissue integrity are present.

Total Ankle Arthroplasty

Total ankle arthroplasty is considered medically necessary in skeletally mature patients when ALL of the following criteria are met:

  • Radiographic confirmation of advanced/end-stage arthritis of the tibiotalar joint
  • Significant pain and functional impairment due to arthritis of the ankle persist after at least 3 months of supervised conservative management
  • Documentation of adequate lower extremity vascular perfusion (e.g., strong, palpable pedal pulses)
  • Device is FDA approved

Total ankle arthroplasty may also be indicated for revision of failed previous reconstructions where sufficient bone stock and soft tissue integrity are present.

Revision Total Ankle Arthroplasty

Revision total ankle arthroplasty is considered medically necessary in skeletally mature patients when ALL of the following criteria are met:

  • Radiographic confirmation of implant problem
  • Significant pain and functional impairment due to the identified implant problem
  • Documentation of adequate lower extremity vascular perfusion (e.g., strong, palpable pedal pulses)
  • Device is FDA approved

Contraindications

All ankle arthroplasty procedures

  • Active infection of the joint
  • Active systemic bacteremia
  • Charcot neuroarthropathy
  • Active skin infection
  • Inadequate bone stock
  • Severe anatomic deformity in adjacent ankle structures, including hindfoot, forefoot and knee joint
  • Prior surgery or injury that has adversely affected ankle bone quality
  • Extensive avascular necrosis of the talar dome
  • Malalignment (e.g., varus or valgus deformity greater than 15 degrees) not correctable by surgery
  • Peripheral vascular disease
  • Absence of the medial or lateral malleolus or both
  • Severe osteoporosis, osteopenia or other conditions resulting in poor bone quality, as this may result in inadequate bony fixation
  • High demand sports activities (e.g., contact sports, jumping)
  • Immunosuppressive therapy
  • Insufficient ligament support that cannot be repaired with soft tissue stabilization
  • Insufficient musculature such that proper component positioning or alignment is not possible
  • Neurologic impairment with dynamic muscular imbalance across the ankle joint
  • Prior fusion of the ankle
  • Psychiatric problems that hinder adequate cooperation during perioperative period

Exclusions for all ankle arthroplasties

All ankle arthroplasty procedures

Indications other than those addressed in this guideline are considered not medically necessary including, but not limited to the following:

  • Asymptomatic ankle osteoarthritis
  • Surgical intervention solely for the purposes of improved cosmesis
  • Non-FDA approved total ankle replacement devices

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.

Independent Multispecialty Physician Panel (IMPP) review. Procedures for hallux rigidus, hallux valgus, bunionette and lesser toe deformities – removed poor wound healing as a contraindication. Hallux valgus surgery – added allowance for pre-ulcer and criterion for simple exostectomy/resection medial eminence. Separated bunionette surgery indications from hallux valgus surgery; added indication for first MTP joint arthrodesis. Separated metatarsal osteotomy criteria into a standalone indication; added exclusion for improved cosmesis. Ankle arthritis – new indication for revision total ankle arthroplasty. Ankle arthroplasty – removed severe ankle deformity and peripheral neuropathy as contraindications. Added references. Added guidance for correct coding to code section.
