CMS Pub. 100-04, ch. 29, § 240.1
Good Cause
If an appeal request is filed late, the applicable MAC may extend the time limit for filing an appeal if good
cause is shown. The MAC resolves the issue of whether good cause exists before taking any other action on
the appeal. Whenever a MAC makes a finding for good cause for late filing, the MAC shall document the
reason for that finding in the redetermination decision letter. If no decision letter is issued (i.e., a decision
fully favorable to the appellant is made, which currently does not require issuance of a redetermination
decision letter), then the reason the MAC found that good cause exists for late filing shall be documented in
the redetermination case file.
NOTE: A finding by the MAC that good cause exists for late filing for the redetermination does not mean
that the party is then excused from the timely filing rules for the reconsideration.
