    This policy governs coverage of foot surgery, including correction of the first metatarsophalangeal joint with cheilectomy, debridement, and capsular release without implant, for UnitedHealthcare Commercial and Individual Exchange benefit plans. Coverage depends on applicable clinical criteria, benefit-plan terms, and documentation supporting medical necessity.

    POLICY UPDATE CHANGES

    Interposition or interpositional arthroplasty of the first or second metatarsophalangeal joint, using any method, was added as unproven and not medically necessary for limitations in motion or degenerative changes.

    OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.

    Medical Necessity and Coverage Determinations

    Correction without implant

    Covered when all of the following criteria are met:

    All required criteria

    • Procedure: Correction of the first metatarsophalangeal joint with cheilectomy, debridement, and capsular release is performed without an implant.
    • Diagnosis and imaging: The patient has a diagnosis of hallux limitus or hallux rigidus, with radiographic imaging confirming mild to moderate pathology.Mild to moderate pathology

      A grading scale such as the Coughlin and Shurnas or Hattrup and Johnson Classification may be used.

    • Persistent symptoms despite conservative treatment

      • One or more conservative modalities

        • Orthotics, shoe modification (such as a high and wide toe box or rocker-bottom sole), and/or shoe inserts have been tried.
        • Medical therapy, including nonsteroidal anti-inflammatory drugs, analgesics, or intra-articular injections, has been tried.
        • Activity modification has been tried.
        • Debridement of hyperkeratotic lesions has been performed, if present.

    Interposition/interpositional arthroplasty

    Not medically necessary:

    Interposition or interpositional arthroplasty of the first or second metatarsophalangeal joint, using any method, is unproven and not medically necessary for treating limitations in motion or degenerative changes because of insufficient evidence of efficacy.

    Applies to either the first or second metatarsophalangeal joint.

    Under the Community Plan, correction of the first metatarsophalangeal joint with cheilectomy, debridement, and capsular release without an implant is unproven and not medically necessary when hallux rigidus is severe. A grading scale such as the Coughlin and Shurnas or Hattrup and Johnson classification may be used to assess severity.

    Interposition or interpositional arthroplasty of the first or second metatarsophalangeal joint, using any method, is unproven and not medically necessary for treating limitations in motion or degenerative changes because of insufficient evidence of efficacy.

    Osteochondral allograft or autograft transplantation is unproven and not medically necessary for treating cartilage defects of the foot because of insufficient evidence of efficacy.

    Interposition or interpositional arthroplasty of the first or second metatarsophalangeal joint, using any method, is excluded from medically necessary coverage when used to treat limitations in motion or degenerative changes because evidence of efficacy is insufficient.

    For the Community Plan, correction of the first metatarsophalangeal joint with cheilectomy, debridement, and capsular release without an implant is not medically necessary for severe hallux rigidus, due to insufficient evidence of efficacy.

    Interposition or interpositional arthroplasty is not medically necessary when used to treat limitations in motion or degenerative changes of the first or second metatarsophalangeal joint, regardless of the method used.

    Osteochondral allograft or autograft transplantation is not medically necessary for treating cartilage defects of the foot, because evidence of efficacy is insufficient.

    Effective October 1, 2026, the policy identifies interposition or interpositional arthroplasty of the first or second metatarsophalangeal joint, using any method, as unproven and not medically necessary for limitations in motion or degenerative changes because of insufficient evidence of efficacy.

    Documentation and Denial-Risk Guidance

    Documentation Required

    Medical Records May Be Required

    Medical records documentation may be required to assess whether the member meets the clinical criteria for coverage. Documentation supports the clinical review but does not guarantee coverage; coverage is determined by the member-specific benefit plan and applicable laws.

    Documentation Required

    Document Diagnosis and Medical Necessity

    Document the diagnosis and medical necessity for correction of the first metatarsophalangeal joint without an implant. Records should include imaging confirming mild to moderate pathology, persistent pain, and the reasonable conservative treatment trial.

    • Diagnosis of hallux limitus or hallux rigidus
    • Radiographic imaging showing mild to moderate pathology, using a grading scale such as Coughlin and Shurnas or Hattrup and Johnson, when applicable
    • Persistent pain despite conservative treatment, such as orthotics or shoe modification, medical therapy or intra-articular injections, activity modification, and debridement of hyperkeratotic lesions when present

    Clinical Background

    Hallux rigidus causes pain and stiffness at the first metatarsophalangeal joint and may result from osteoarthritis, rheumatoid arthritis, or gout. Hallux limitus generally describes earlier disease with partially restricted motion, while hallux rigidus reflects progressive loss of motion and advanced stiffness. Cheilectomy removes a dorsal bone spur while preserving joint motion and is generally used for early disease or mild joint damage; advanced disease may require arthrodesis or arthroplasty.

    Denial Risk

    Denial Risk: Missing Criteria or Severe Disease

    Correction without an implant is not medically necessary when the required clinical criteria are not documented or when the member has severe hallux rigidus, because evidence is insufficient for the severe condition.

    • Confirm and document all coverage criteria before requesting correction with cheilectomy, debridement, and capsular release.
    • Document disease severity using an applicable grading scale, such as Coughlin and Shurnas or Hattrup and Johnson.
    Denial Risk

    Interposition Arthroplasty Not Medically Necessary

    Interposition or interpositional arthroplasty of the first or second metatarsophalangeal joint, using any method, is unproven and not medically necessary for treating limitations in motion or degenerative changes.

    • Do not submit interposition arthroplasty as medically necessary for these indications absent applicable coverage criteria or benefit provisions.
    Denial Risk

    Osteochondral Transplantation Not Medically Necessary

    Osteochondral allograft or autograft transplantation is unproven and not medically necessary for treating cartilage defects of the foot due to insufficient evidence of efficacy.

    • Expect denial risk when osteochondral transplantation is requested for foot cartilage defects.

    Revised Policy: Interposition Arthroplasty

    Effective October 1, 2026, the revised policy expressly addresses interposition or interpositional arthroplasty of the first or second metatarsophalangeal joint, using any method, as unproven and not medically necessary for limitations in motion or degenerative changes.

    • Apply the revised policy language to applicable claims and requests.
    • Verify the current policy version rather than relying on archived policy 2026T0624O.
