Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Continuation Therapy Criteria

General Continuation Exemption

Continuation requests for a not-approvable medication shall be exempt provided ALL of the following are met:

ref": "b2_0

title": "General Continuation Exemption

ref_exact?": null}

ref b2_0

Continuation and administration constraints: Continuation requests are governed by the policy's continuation exemptions and may be allowed when criteria are met; specific treatment duration limits apply in the adjuvant setting including a maximum total duration of 1 year (12 months) for adjuvant melanoma and an adjuvant duration limit of up to 12 months for resected NSCLC. Single-dose administration limits that may lead to claim exclusion are 200 mg every 3 weeks (q3w) or 400 mg every 6 weeks (q6w).

Unproven / Not Supported Uses

Not Supported / Exclusions

Small Cell Lung Cancer (SCLC) exclusion: Single-agent Keytruda is NOT supported for metastatic SCLC following progression on platinum-based chemotherapy and/or at least one other line of therapy (e.g., topotecan, irinotecan, paclitaxel, docetaxel)

Rationale: FDA indication withdrawn/confirmatory study KEYNOTE-604 failed to meet OS endpoint

Soft Tissue Sarcoma exclusions: Single-agent Keytruda is NOT supported for the following sarcomas: cutaneous angiosarcoma; undifferentiated sarcomas; myxofibrosarcoma; undifferentiated pleomorphic sarcoma

Rationale: lack of Level 1 evidence showing superior outcomes

Unsupported combinations: Keytruda + cetuximab combination is not supported for initial and subsequent treatment of non-nasopharyngeal head and neck cancers

Lack of Level 1 evidence

NSCLC unsupported combo: Keytruda + Carboplatin + Abraxane (nab-paclitaxel) is not supported for NSCLC per policy

Based on KEYNOTE-407 results showing equivalent PFS and OS with Abraxane and Taxol

TNBC unsupported combo: Keytruda + Abraxane (nab-paclitaxel) regimen is not supported for recurrent unresectable or metastatic breast cancer per policy

Based on KEYNOTE-355 results showing equivalent outcomes with Abraxane and Taxol

Other exclusions and provider action notes: Providers must submit requests supported by FDA labeling, CMS-recognized compendia, NCCN/ASCO guidelines, or acceptable peer-reviewed literature and document required biomarkers. The policy notes withdrawn or unsupported FDA indications (for example, single-agent pembrolizumab is not supported for metastatic SCLC following progression) and lists other unsupported uses (selected soft tissue sarcomas and certain combinations). Final coverage decisions vary by member benefit and are subject to Evolent utilization management processing and plan terms.

Provider Actions / Prior Authorization

Prior Authorization

Authorization required and UM processing

Evolent is responsible for processing all medication requests; medications not authorized may be deemed not approvable and not reimbursable. Requests must be supported by FDA-approved product labeling, CMS-recognized compendia, NCCN/ASCO guidelines, or acceptable peer‑reviewed literature.

Documentation Required

Biomarker documentation

For indication-specific requests, document relevant biomarker results to meet coverage criteria. Examples include PD‑L1 (CPS or TPS) per indication thresholds (e.g., CPS/TPS ≥1% or ≥50% as required), MSI‑High or dMMR confirmed by a standardized test, tumor mutational burden (TMB) ≥10 mut/Mb, and EGFR/ALK negative status when required for first‑line NSCLC.

Denial Risk

Exclusion for dosing/length limits

Claims may be excluded when dosing or treatment duration exceed policy limits. Single‑dose limits are 200 mg every 3 weeks or 400 mg every 6 weeks. Adjuvant treatment duration in the resected melanoma or NSCLC settings is limited to a maximum of 12 months. Affected HCPCS code: J9271.

Denial Risk

Exclusion for prior progression / withdrawn indications

Avoid uses that the policy excludes to prevent claim denials. Examples of unsupported or withdrawn/unsuitable uses include single‑agent pembrolizumab for metastatic SCLC following progression on platinum‑based chemotherapy and/or additional lines of therapy, certain soft tissue sarcoma subtypes (cutaneous angiosarcoma, undifferentiated sarcomas, myxofibrosarcoma, undifferentiated pleomorphic sarcoma), and combinations or indications not supported by FDA labeling, CMS compendia, or acceptable peer‑reviewed evidence.

Clinical Evidence & References

References cited: Primary evidence sources include multiple KEYNOTE trials and publications (KEYNOTE-826, KEYNOTE-859, KEYNOTE-671, KEYNOTE-604, KEYNOTE-407, KEYNOTE-522, KEYNOTE-426 and others), articles in NEJM and Lancet, NCCN guidance, and the Keytruda prescribing information (2024).

Background

Background and policy scope: The policy defines accepted indications for pembrolizumab including FDA-approved uses and select off-label uses supported by compendia and guidelines. Evolent Clinical Guidelines are used for utilization management but do not constitute medical advice; final coverage varies by member benefit and plan terms.

Definitions
