Detailed Explanation of Non-Coverage (DENC): what it means and what to do

The provider's stated reasons for a termination, sent after a beneficiary requests QIO review. Not itself separately appealable.

A Detailed Explanation of Non-Coverage isn't itself something you appeal — it's the facility's own written case for why coverage is ending, sent to the QIO once you've requested a fast appeal.

It typically arrives quickly, since the QIO's own 72-hour clock depends on having it.

The DENC's reasoning is the facility's own — not an independent medical judgment — which is exactly why an independent QIO review exists to check it.

Reading the DENC carefully often reveals exactly what the QIO's decision will turn on — the specific clinical basis the facility is relying on, whether that's a lack of continued skilled need, a plateau in progress, or a change in the patient's level of care. Knowing that basis ahead of time is useful even though the QIO already has the document, since it tells you what evidence is actually worth gathering before the decision comes back.

If the DENC's stated reasoning doesn't match what you're actually observing day to day — your parent still receiving skilled nursing visits, still needing help with the same tasks — that gap between the paperwork and the reality is itself worth raising directly, whether by calling the QIO back or by asking the facility for clarification.

Read it for the facility's own reasoning. The DENC is the facility's stated reasons for why the covered service is ending — sent after you've already requested QIO review, not before.

Compare it against the actual facts. This is the document to check point-by-point against your parent's own recent records — is the stated reason for ending care accurate right now, not just at some earlier point in the stay?

Give it to the QIO. The QIO already has it (the facility sends it directly), but reading it yourself is what tells you what the review will actually turn on.

A DENC isn't a bill, and it isn't a separate deadline — no response or acknowledgment is required from the family. It exists purely to give the QIO (and you) the facility's own written case, on the same 72-hour clock the original fast-appeal request already started.
