Prior Authorization, Documentation, and Off‑Label Use

Prior authorization is required and approval is contingent on meeting the clinical criteria in this policy. Providers must submit documentation (such as office chart notes, laboratory results, treatment history, and other pertinent clinical information) demonstrating that the member meets all applicable approval criteria, including indication, dosing, prior therapies, and response to therapy.

• Failure to submit required documentation may result in denial of the request or delay in processing.
• Documentation that a member is currently receiving the medication for a covered oncology indication for at least 30 days, or evidence that the member previously met initial approval criteria, may support continuation requests.
• For off‑label (non‑FDA) indications not specifically addressed in this policy, the prescriber must submit supporting peer‑reviewed literature or guideline evidence and follow applicable off‑label use policies: CP.CPA.09 (commercial), HIM.PA.154 (health insurance marketplace), and CP.PMN.53 (Medicaid).

Coding and Billing Risks

Providers should ensure that billed diagnosis and drug codes match the HCPCS/J‑codes and ICD‑10 codes referenced by this policy. Coding mismatches or use of unsupported codes may trigger claim denials or require claim adjustment.

• Codes referenced for informational use include: J9035, C9257, Q5107, Q5118, Q5126, Q5129, Q5160, and J9999.
• Inclusion or exclusion of codes in this policy does not guarantee coverage; providers must reference up‑to‑date professional coding guidance prior to claim submission.

Coverage Document Compliance

Coverage decisions are guided by this clinical policy but remain subject to the member’s specific coverage documents and Health Plan administrative policies. Meeting clinical criteria does not guarantee payment; benefit limitations, exclusions, prior authorizations, and other plan terms apply.

• Coverage determinations are subject to the terms, conditions, exclusions, and limitations of the member’s evidence of coverage, certificate of coverage, or contract.
• State and federal statutory requirements and Health Plan‑level administrative policies and procedures may affect coverage; providers should consult member benefit documents and plan addenda (including state‑specific appendices) as needed.

Required Documentation and Adherence

Providers must adhere to the requirements in this clinical policy when submitting prior authorization requests and supporting materials. Failure to comply with required documentation or to follow plan‑level administrative policies may result in denial, delay, or rescission of authorization.

• Follow plan‑level administrative policies and any applicable state addendums (e.g., continuity of care provisions or state restrictions on step therapy described in Appendix E).
• For requests involving dosing outside FDA limits, include supporting evidence from practice guidelines or peer‑reviewed literature as specified in the policy.
