Integrated Denial Notice (IDN): what it means and what to do

The plan's written denial of a service, item, or claim — coverage OR payment. Includes pre-service and payment denials alike.

An Integrated Denial Notice is the plan's formal written denial — of a service, an item, or a payment. It's required to explain what was denied, why, and how to appeal it.

It isn't the final word. Medicare Advantage plans have to follow specific coverage rules, and a denial that doesn't square with those rules is exactly the kind of case that tends to win on appeal.

65 days from the date on the notice. The rule (42 CFR § 422.582) gives you 60 days from when you receive the denial, and receipt is presumed to be 5 days after the notice's own date unless shown otherwise — 60 + 5 = 65 days from the notice date.rule42 CFR 422.582

The notice is required to state what was denied and why — but "why" often means a short, generic phrase like "not medically necessary" rather than the actual rule the plan applied. Getting the real rule behind that phrase is usually the difference between an appeal that argues in circles and one that argues from something specific.

Two kinds of IDNs exist: one for a service you haven't received yet (pre-service) and one for a bill for something already provided (payment). Which kind you have changes both the plan's own deadline to answer and, sometimes, whether expedited review is available at all.

Read it for the what, why, and when. Find what was denied, the plan's stated reason, and the date printed on the notice — that date starts your clock.

Get the plain-language explanation. A free explanation tells you which Medicare rule governs this kind of denial and whether the plan's own stated reason actually holds up against it.

Gather the evidence the rule asks for. Different denials call for different evidence — a discharge summary, a physician's order, a test result — matched to the specific rule the plan cited.

File before the deadline. 65 days from the date on the notice. The rule (42 CFR § 422.582) gives you 60 days from when you receive the denial, and receipt is presumed to be 5 days after the notice's own date unless shown otherwise — 60 + 5 = 65 days from the notice date.
