From K.Actuary, founded by Sangmin Kwon, ASA · sources checked 2026-11-06 · Source: GovInfo · 29 CFR § 2560.503-1 «Claims procedure: notice of an adverse benefit determination» · paragraph (g)(1) View original ↗

In short

A not covered denial is based on the plan's written terms.
The notice must name the exact part of the plan it used.
Read that part of your plan, ask for your claim file, and appeal.

What this means

The federal claims rule for employer group health plans says a «not covered» or «excluded» denial must give the specific reason [1]. It must also refer to the plan provisions the decision is based on [1].

Read those provisions next to your plan document. You can also get the documents about your claim free on request [2]. An employer group plan must give you at least 180 days after you receive the notice to appeal [3]. The external review process must allow at least four months after the notice to ask for it [4].

For urgent care, the plan must decide on review as soon as possible, not later than 72 hours after it gets your request [5]. For a pre-service claim under a group health plan that provides for one appeal, the limit is 30 days [5].

Your next step

Read the plan provisions named in the notice next to your plan document. Ask the plan for your claim documents, which must be free on request [2]. Send your appeal within the time on the notice; an employer group plan must give you at least 180 days [3].
