(a) General. The manufacturer of a Part B rebatable drug may submit a Suggestion of Error about the information in their Preliminary Rebate Report and the report detailing the preliminary reconciliation of the rebate amount to CMS, for its discretionary consideration, if the manufacturer believes that there is a mathematical error or errors to be corrected before the Rebate Report or a subsequent reconciliation of the rebate amount, as applicable, is finalized.

(2) [Reserved] (b) Process of submission. Subject to the scope and timing requirements specified in paragraphs (a) and (c) of this section, manufacturers may submit the Suggestion of Error and provide supporting documentation (if applicable). (c) Timing. Except as set forth in § 427.502 for applicable calendar quarters in calendar year 2023 and 2024, a manufacturer must submit its Suggestion of Error for the applicable calendar quarter within 10 calendar days from the date of receipt of a Preliminary Rebate Report or a preliminary reconciliation of a rebate amount using the method and process established by CMS in paragraph (b) of this section. (d) Notice. (1) CMS will include any revisions to the calculation of the rebate amount, if determined necessary by CMS based on the Suggestion of Error submitted under this section prior to issuance of the Rebate Report as set forth in § 427.501(c) or § 427.502(c) as well as any report of reconciled rebate amount as set forth in § 427.501(d) or § 427.502(c)(2)(ii).
