Original Medicare Appeal Timing in the Cited Records

The cited regulation states that a request for redetermination must be filed within 120 calendar days from the date a party receives the initial determination notice. CMS-20027 includes a field for a late-filing reason. Medicare.gov states a 180-day period for a level-2 reconsideration after a MAC decision letter or an MSN. This article reports these statements without applying them to an individual appeal.

This original record-reading guide is a general reading aid, not cited evidence. It does not depict a source record; the article text and source links provide the facts.

Key points

• The regulatory redetermination deadline is 120 calendar days from the date you receive the initial determination notice (42 CFR 405.942).
• The CMS-20027 form has a built-in field for late filers to state their reason, showing a good-cause exception exists (CMS-20027).
• CMS-20027 is labeled “OMB Exempt” and, unlike most CMS forms, does not carry a standard expiration date (CMS-20027).
• A second-level appeal (Reconsideration by a Qualified Independent Contractor) must be filed within 180 days of the MAC’s decision letter or an MSN (Medicare.gov).
• Medicare.gov instructs appellants to file by the date printed on their own MSN, not by a self-calculated deadline (Medicare.gov).

The 120-Day Redetermination Window

The federal regulation governing Original Medicare appeals states: “any request for redetermination must be filed within 120 calendar days from the date a party receives the notice of the initial determination” (42 CFR 405.942). This is the first-level appeal — the redetermination — for a denied Part A or Part B claim.

The regulation’s history is recorded in its own citation line: “[70 FR 11472, Mar. 8, 2005, as amended at 74 FR 65333, Dec. 9, 2009]” (42 CFR 405.942). That amendment date, December 9, 2009, marks the most recent change reflected in the current text of this section.

Good Cause for Late Filing

The redetermination request form itself acknowledges that late filings are possible. CMS-20027 instructs: “If you received your initial determination notice more than 120 days ago, include your reason for the late filing:” (CMS-20027). This line on the official form is the evidence that a good-cause exception to the 120-day window exists — the form provides a place to explain the delay rather than rejecting late requests outright.

The CMS-20027 form label

The form used to request a redetermination is identified as “Form CMS-20027 (01/20)” and is marked “OMB Exempt” (CMS-20027). This article reports those displayed form labels without inferring their administrative effect.

Level-two appeal deadline

If the redetermination decision is not in your favor, there is a second appeal level. Medicare.gov states: “You have 180 days after you get the MAC’s decision letter or an MSN to ask for a level 2 appeal, called a ‘Reconsideration’ by a Qualified Independent Contractor (QIC).” (Medicare.gov). This article identifies that this 180-day clock exists; it does not describe what happens procedurally beyond this second level.

The date stated on an MSN

Medicare.gov states: “You must file your appeal by the date in the MSN.” (Medicare.gov). This article reports that instruction alongside the regulation’s quoted 120-calendar-day text without reconciling them for an individual appeal.

This article also does not evaluate whether any particular claim denial was correct, address the medical necessity of any denied item or service, predict whether an appeal will succeed, or cover Medicare Advantage (Part C) or Part D appeal deadlines and forms — those follow different rules than the Original Medicare (Part A/B) redetermination process described here.
