Determine whether a Medicare Part D payer requires prior authorization for a drug. Answers are deterministic projections of payers' own formularies as filed with CMS — no model is in the path, and identical input always yields identical output. Every answer cites the CMS document and its effective date. FOUR BOUNDARIES BELONG IN ANY ANSWER YOU GIVE A USER: (1) This covers Medicare Part D DRUG benefits only — never medical or procedure prior authorization, never commercial/employer plans, never Medicaid. (2) A status of `not_on_formulary` means the drug is NOT COVERED by that payer's plans; it does not mean prior authorization is unnecessary, and it is generally a worse outcome for the patient. (3) A status of `varies` means requirements differ across that payer's plans — the member's specific plan, on their insurance card, decides. (4) `unknown` means we hold no filing; it never means 'no prior authorization required'. This is administrative information, not medical advice, not a coverage guarantee and not an authorization. Always surface `notices` verbatim.
