sponsor affirms, in whole or in part, its decision related to an at-risk determination, the Part D
plan sponsor must forward the case to the IRE contracted with CMS within 24 hours. See §
423.590(i). For additional information and requirements on the drug management programs that
a plan sponsor may utilize, see the Improving Drug Utilization Review Controls page on the Part
D website.
40.4 – Prior Authorization and Other Utilization Management Requirements
Part C Only
An enrollee, enrollee’s representative, or a provider on behalf of the enrollee, has the right to
voluntarily request plan approval (either pre-service or concurrent to receiving services) in
circumstances where there is a question whether the plan will cover a service, item, or Part B
drug. An enrollee’s right to voluntarily receive plan approval extends to any service, item, or
Part B drug which the enrollee believes is or should be covered by the plan (this includes non-
covered services, items, and Part B drugs and those for which the plan does not require prior
authorization (PA) as a condition for coverage in its annual Evidence of Coverage).
When a plan processes a coverage request that involves mandatory PA or other utilization
management (UM) requirement, such as step therapy for Part B drugs, the plan’s determination
on whether to grant approval of a service, item, or Part B or D drug for an enrollee constitutes an
initial determination and is subject to appeal. In addition, if a plan denies coverage of a service,
item, or Part B or D drug because the enrollee failed to seek PA or failed to comply with similar
limits on coverage, the denial also constitutes an initial determination and is subject to appeal.

Partially adverse determinations include coverage decisions in which the MA plan approves a
PA request at a reduced level (or approves an altogether different service, item, or Part B or D
drug) than the service, item, or Part B or D drug requested. Thus, the adjudication timeframe,
notice, and other requirements applicable to coverage determinations or organization
determinations under Part 422, Subpart M & Part 423, Subpart M apply to requests that involve
a PA or other UM requirements in the same manner that they apply to all coverage requests. If
an enrollee requests coverage of a service, item, or Part B or D drug, the plan is to respond to the
PA request, and should contact the physician or prescriber for information needed to satisfy the
PA, in accordance with the outreach guidance at §10.6. Plans, however, should not use peer-to-
peer discussions to solicit substantive modification to pending PA requests in order to improve
likelihood for approval (e.g. a peer-to-peer discussion suggesting the physician or prescriber
modify a pending PA request to a lower level of service in order to receive plan approval).
Coverage and medical necessity decisions are initial determinations subject to notification and
appeal requirements. MA plans may not interfere with an enrollee’s right to receive a requested
initial determination or obstruct the enrollee’s access to the appeal process by any means.
Part D Only
The decision to place a medication on a PA list or subject it to a UM requirement is not a
coverage determination and is not subject to appeal. However, an enrollee may request that the

For Part D, this denial would occur after an enrollee has formally requested a coverage determination with a Part D
plan sponsor because, as indicated in §40.2
above, the presentation of a prescription at the pharmacy counter is not
considered a request for a coverage determination unless a plan sponsor chooses to treat it as such.
