In a landmark regulatory move, the Centers for Medicare and Medicaid Services (CMS) unveiled a sweeping proposed rule on Monday, July 13, 2026, aimed at drastically reducing prior authorization delays and improving care continuity for millions of Medicare Advantage enrollees.

The 2027 Medicare Advantage and Part D proposed rule introduces stringent new timelines for coverage determinations. Under the new framework, health plans would be mandated to approve or deny urgent prior authorization requests within 72 hours, down from the current 14-day standard, while standard requests would face a strict 7-day deadline .

The proposal also mandates that Medicare Advantage plans utilize standardized, evidence-based clinical criteria that align closely with traditional Medicare coverage policies. Furthermore, plans failing to meet the new turnaround times would face poignant financial penalties and potential downgrades in their annual Star Ratings, directly impacting their ability to attract beneficiaries during open enrollment.

Patient advocacy groups, including the Medicare Rights Center, have applauded the initiative, citing decades of data linking prior authorization delays to adverse health outcomes and increased hospital readmissions. Conversely, the trade group America’s Health Insurance Plans (AHIP) expressed concern, warning that accelerated timelines could strain administrative infrastructure and inadvertently lead to more blanket denials if not paired with adequate technological integration.
