(a) Method and place for filing a request. An enrollee or an enrollee's prescribing physician or other prescriber (acting on behalf of the enrollee) must ask for a redetermination by making a written request with the Part D plan sponsor that made the coverage determination or the at-risk determination under a drug management program in accordance with §423.153(f). The Part D plan sponsor may adopt a policy for accepting oral requests.

(b) Timeframe for filing a request. Except as provided in paragraph (c) of this section, a request for a redetermination must be filed within 60 calendar days from the date of the notice of the coverage determination or the at-risk determination under a drug management program in accordance with §423.153(f).

(c) Extending the time for filing a request—(1) General rule. If an enrollee or prescribing physician or other prescriber acting on behalf of an enrollee shows good cause, the Part D plan sponsor may extend the timeframe for filing a request for redetermination.

(2) How to request an extension of timeframe. If the 60 calendar day period in which to file a request for a redetermination has expired, an enrollee or a prescribing physician or other prescriber acting on behalf of an enrollee may file a request for redetermination and extension of time frame with the Part D plan sponsor. The request for redetermination and to extend the timeframe must—

(i) Be in writing; and

(ii) State why the request for redetermination was not filed on time.

(d) Withdrawing a request. The person who files a request for redetermination may withdraw it by filing a written request with the Part D sponsor.
