Authorization Denial Management

Authorization denial management is the coordinated process of preventing, tracking, appealing, and root-causing denials tied to coverage and authorization requirements. In hospice and home care it is most consequential under Medicare Advantage (MA) and managed Medicaid, because traditional fee-for-service Medicare hospice does not require prior authorization.

Under traditional Medicare, hospice denials stem from eligibility, certification, NOE timeliness, and coverage — not from prior authorization, which the FFS hospice benefit does not use. As enrollment shifts toward Medicare Advantage and managed Medicaid, however, plans apply prior authorization, concurrent review, and their own medical-necessity criteria, which reintroduces authorization-based denials to a benefit that historically had none. Oversight has flagged how often those denials are wrong: an HHS Office of Inspector General review found that 13 percent of prior-authorization requests denied by MA organizations met Medicare coverage rules and likely would have been approved under traditional Medicare, and 18 percent of denied payment requests met both Medicare coverage rules and MA billing rules ^[1]. Effective denial management categorizes each denial by its CARC/RARC, separates true denials from routine adjustments using reconciled remittance data, and routes appealable denials into the correct workflow before the deadline — beginning, for Medicare, with redetermination by the MAC and reconsideration by a Qualified Independent Contractor. The final loop is root-cause analysis: feeding denial patterns back into front-end scrubbing and authorization capture so the same denial reason stops recurring.

The strategic error is treating denials as a back-office cleanup task rather than a payer-behavior signal. OIG's findings mean a meaningful share of MA and managed-Medicaid denials are overturnable, so a low appeal rate is not evidence of clean billing — it is often unclaimed revenue forfeited by inaction. As payer mix tilts toward managed plans, denial exposure rises structurally, and front-end authorization capture combined with a disciplined appeals calendar produces better financial outcomes than additional rework staffing. Denial rate, appeal rate, and overturn rate measured by payer reveal which plans' initial denials are not defensible — a high overturn rate signals that the denials were issued in error, not that the billing was wrong.
