PACE (Program of All-Inclusive Care for the Elderly) denied which external review to choose after an unfavorable appeal decision? What the rule says and how to appeal.

Checked against the current rules on September 24, 2026.

A denial for which external review to choose after an unfavorable appeal decision isn't the end of the story — PACE organizations have to follow specific coverage rules, and a denial that doesn't square with those rules is exactly the kind of appeal that tends to win.

Here's what the rule actually requires, what evidence usually turns a denial around, and the deadline you're working against.

What the rule requires

Coverage for which external review to choose after an unfavorable appeal decision under your PACE organization is governed by§ 460.124 Additional appeal rights under Medicare or Medicaid.. Your PACE organization generally cannot apply a stricter test than what these rules require.

Questions that decide it

Before you appeal, these are the facts that usually decide whether a denial like this holds up:

What a winning appeal has to show

An appeal that wins usually includes:

Your deadline to appeal

No deadline to make this first request — a participant, their designated representative, or their caregiver may request it at any time, orally or in writing.42 CFR 460.121

Your PACE organization itself then has its own clock to decide. As expeditiously as the participant's condition requires, but no later than 3 calendar days from the request — extendable by up to 5 calendar days.

Questions people ask

Can your PACE organization just say it's "not medically necessary" with no further explanation?
The denial notice has to explain the basis for the decision and tell you how to appeal. If it doesn't point to a specific rule or criteria, that's itself worth raising in your appeal — you're entitled to know what standard was applied.
What if I don't have all the evidence listed above?
Include what you have. An appeal with partial evidence and a clear explanation of the rule still gets a real review — it doesn't need to be complete to be worth filing.
