Waiver, compromise, and appeal — three different ways to answer an MSP demand
An MSP demand letter can be answered three different ways, and it matters which one you're actually making — only two of the three carry a formal right to appeal if Medicare says no.
Source: Medicare Secondary Payer Manual, Chapter 7 — MSP Recovery (§§ 40.21-.25 appeals; § 50 waiver/compromise).
An appeal disputes the demand itself — that specific claims aren't related to your case, or that the amount is calculated wrong. This is a real appeal with formal levels and deadlines, the same claims-ladder process (redetermination, then reconsideration by a Qualified Independent Contractor, then further review) used for an ordinary denied Medicare claim.Medicare Secondary Payer (MSP) Manual, Chapter 7 — MSP Recovery
A waiver of recovery, under Section 1870(c) of the Social Security Act, asks Medicare to forgive some or all of a debt you don't dispute owing — because you were without fault and repaying it would either cause real financial hardship or be against equity and good conscience. A less-than-fully-favorable waiver decision can itself be appealed.Medicare Secondary Payer (MSP) Manual, Chapter 7 — MSP Recovery
A compromise request, under the Federal Claims Collection Act, asks Medicare to accept less than the full amount for a different reason entirely — that full collection isn't realistic, that Medicare would likely lose if the claim were litigated, or that collecting the rest would cost more than it's worth. This is a discretionary negotiation with CMS, not an appeal, and a compromise decision itself carries no formal appeal right.Medicare Secondary Payer (MSP) Manual, Chapter 7 — MSP Recovery
You can ask for more than one at once
Requesting a waiver doesn't require giving up an appeal, and the two can be filed together — Medicare processes the appeal of the underlying debt first, then evaluates the waiver only if the debt itself is upheld.
When both are filed together, the BCRC sends one combined acknowledgment and, later, one combined decision letter — the family doesn't have to track two entirely separate cases with two separate contacts.
Interest doesn't wait for any of the three
Interest on the underlying debt accrues from the date of the demand letter itself, assessed every 30 days, regardless of whether an appeal, a waiver request, or a compromise request is pending. Paying the demand amount now stops further interest from accruing — and if the dispute later succeeds, the payment (interest included) is refunded.
