Medicare denied something on your MSN? Here's the clock

The answer: under Medicare Part A/B appeals — 42 CFR §405.942, you can request redetermination of anything denied on your Medicare Summary Notice within 120 days of the initial determination — and receipt of the notice is presumed 5 days after the notice date (42 CFR §405.942 — request redetermination within 120 days of the initial determination (the MSN); receipt is presumed 5 days after the notice date).
