Why Medicare (Original + Advantage) denies residential and level-of-care
Medicare is a federal program with two delivery modes — Original (fee-for-service Part A/B + Part D drug plans) and Advantage (private MA-C plans). Each has its own appeal ladder, and rights are stronger than most beneficiaries realize.

Common Medicare (Original + Advantage) denial patterns for residential and level-of-care
- Original Medicare: 5-level appeal. Redetermination by MAC → reconsideration by QIC → ALJ hearing → Medicare Appeals Council → federal district court. The QIC and ALJ levels reverse a substantial share of denials when properly briefed.
- Medicare Advantage: identical 5-level ladder. MA plans must follow the same federal appeal structure as Original Medicare. Plan-level reconsideration → Independent Review Entity (Maximus) → ALJ → Council → federal court.
- Part D drug coverage denials. Part D appeals follow a separate but parallel ladder. Tiering exceptions and formulary exceptions are filed before a coverage determination challenge.
The reversal pathway for residential and level-of-care appeals
Successful residential and level-of-care appeals against Medicare (Original + Advantage) typically require:
- Procedural-rights anchor. Every Medicare (Original + Advantage) denial triggers ERISA § 503 or 45 C.F.R. § 147.136 procedural rights. The cover letter must invoke these in the opening paragraph to lock the timeline and force criteria disclosure.
- Criteria-disclosure demand. Medicare (Original + Advantage) (like all major insurers) frequently denies on "not medically necessary" without disclosing the clinical criteria applied. Federal law requires they disclose on request — and once they do, the criteria become the rebuttal map.
- Treating-provider attestation. A letter from the treating physician explaining medical necessity in the specific terms the carrier's policy uses. This is the single strongest evidentiary element.
- Peer-reviewed citations. At least two journal citations (NEJM, JAMA, Lancet, etc.) or specialty-society guidelines (NCCN, AASM, ACR Appropriateness Criteria) supporting the requested service for the patient's clinical profile.
- Plan-language anchor. The specific policy section that controls the determination, quoted verbatim with policy section number.
- Requested action. Clear, specific request for reversal — not a general "please reconsider."
