Do you trust that insurer prior authorization systems are working fairly for patients and providers?

Medical practices report that insurance companies frequently deny claims despite having granted prior authorization for the services. This operational friction leaves some medical service providers with unpaid claims for a year or longer.

Why it matters

Insurers use prior authorization to manage service utilization, but the current breakdown in payment certainty complicates revenue cycle management for providers. This ongoing instability has prompted medical practice leaders to lobby for federal legislative intervention.

The CMS prior authorization model currently covers 17 specific services, while 290 House cosponsors have backed the Improving Seniors' Timely Access to Care Act. Some medical practices report waiting over a year for payment on authorized services despite these ongoing policy tests.

The players

Medical Group Management Association

A trade association representing group medical practices that advocates for regulatory and reimbursement reform.

Centers for Medicare & Medicaid Services

The federal agency responsible for overseeing Medicare programs and conducting utilization management pilot tests.

The details

Practices currently submit clinical information via electronic health record templates to insurers, who often rely on third-party portals and legacy fax systems for communication. Despite receiving formal authorization, providers face persistent denials and downcoding practices that can delay reimbursement for months or years. These administrative barriers force clinics to divert labor resources toward manual claims reconciliation and appeals processes rather than patient care.

January 1, 2026: CMS launched a new prior authorization testing model.
June 2026: Federal legislation reached 290 House cosponsors.
December 2025: A practitioner transitioned from Texas to Colorado.

Market Landscape

The push for federal regulation follows the momentum of the Improving Seniors' Timely Access to Care Act, which has gained significant legislative support. This effort mirrors a broader industry shift toward curbing administrative burdens imposed by Medicare Advantage utilization management tactics.

Operators should evaluate their internal revenue cycle workflows to account for extended payment delays on authorized services. Financial teams should monitor upcoming legislative developments regarding downcoding and potential reimbursement caps.

The takeaway

Prior authorization has become an unreliable metric for guaranteed revenue, necessitating tighter tracking of aging accounts receivable. Practices should prepare for future legislative shifts as the Medical Group Management Association targets prohibitions on downcoding in the next Congress.
