New Medicare Rule Forces Insurers to Decide Faster - Here's Your New Timeline

Medicare Advantage insurers now have less time to decide whether they will cover certain medical services. Beginning January 1, 2026, plans generally must respond to standard prior authorization requests within seven calendar days, down from the previous maximum of 14 days. Expedited requests still require a decision within 72 hours.

For older Americans waiting on rehabilitation, medical equipment, imaging, or another covered service, cutting the standard timeline in half could help prevent treatment from getting stuck in administrative limbo. That matters when health costs are already high, and retirement savings are stretched thin.

Here is what the new Medicare prior authorization timeline means and how beneficiaries can protect themselves.

The new deadline is seven calendar days

Medicare Advantage plans must now decide standard prior authorization requests within seven calendar days. Before January 1, 2026, plans generally had up to 14 calendar days to respond.

The deadline is a maximum, not a target. Plans are still expected to make decisions as quickly as a beneficiary's medical condition requires. Because the rule uses calendar days, weekends and holidays count toward the seven-day limit.

Urgent requests must be decided within 72 hours

The deadline for an expedited, or urgent, request is 72 hours. This timeline did not shrink from the previous Medicare Advantage standard, but it remains an important protection when waiting could seriously harm a person's health or ability to regain function.

A beneficiary or physician may request an expedited decision. A doctor does not have to participate in the plan's network to make that request.

Why a shorter standard timeline matters

Prior authorization can determine whether an insurer pays for a service before the care is provided. A delay may therefore postpone treatment, discharge to a rehabilitation facility, diagnostic testing, or access to medical equipment.

A federal watchdog previously found that Medicare Advantage organizations sometimes delayed or denied care that met Medicare coverage rules. Even when a denial was eventually reversed, the additional steps could create avoidable delays for patients and extra work for their providers.

Some denials have involved covered care

The Department of Health and Human Services Office of Inspector General examined a sample of denials from 15 large Medicare Advantage organizations. It found that 13% of the denied prior authorization requests it reviewed met Medicare coverage rules and likely would have been covered under original Medicare.

Examples include advanced imaging and stays in post-acute facilities, such as inpatient rehabilitation. The report also found cases in which plans said documentation was insufficient, even though reviewers considered the medical records adequate.

Plans must explain why a request was denied

A denial can no longer rely solely on unclear or generic language. Beginning in 2026, affected insurers must give the requesting provider a specific reason when they deny prior authorization for a medical item or service.

That explanation could help a provider identify missing documentation, correct an error, or prepare a stronger appeal.

Insurers must publish their authorization data

The rule also requires plans to post prior authorization metrics on a public-facing website each year. The first reports, covering 2025 data, were due by March 31, 2026.

The required information includes:

• Standard and expedited approval rates
• Standard and expedited denial
• The percentage of standard requests approved after appeal
• Average and median decision times
• A list of medical items and services requiring authorization

These reports could help beneficiaries compare how plans handle prior authorization, although the figures are aggregated and may not show how a plan treats specific procedures.

The rule covers more than Medicare Advantage

The shortened deadlines apply to Medicare Advantage organizations, state Medicaid programs, Medicaid managed care plans, state Children's Health Insurance Program programs, and CHIP managed care entities.

Qualified health plans sold through federally facilitated ACA exchanges are covered by some portions of the final rule, including public reporting and specific denial reasons. However, CMS excluded those exchange plans from the seven-day and 72-hour decision deadlines finalized for 2026.

Prescription drug requests are treated separately

The 2026 deadlines apply to prior authorization for medical items and services, not prescription drugs. Medicare Part D coverage determinations continue to follow separate requirements.

CMS proposed another rule in April 2026 that would extend electronic prior authorizations, faster decisions, and additional transparency requirements to drugs. However, that proposal had not been completed as of July 2026, so beneficiaries should not assume the new seven-day medical-service deadline applies to a Part D prescription request.

Track the date your plan receives the request

Beneficiaries should ask both their provider and insurer whether a procedure, service, or piece of equipment requires prior authorization. When a request is submitted, write down the date the plan received it and whether it was filed as standard or expedited.

For a standard request, follow up if no decision is received within seven calendar days. For an expedited request, the maximum is 72 hours. Keep copies of notices, reference numbers, portal messages, and the names of plan representatives.

Bottom line

The new Medicare Advantage deadlines could make prior authorization decisions more predictable, especially for beneficiaries waiting on non-urgent care. Plans generally have seven calendar days for standard requests and 72 hours for expedited ones, and denials should include a clear explanation that can help patients and doctors decide what to do next.

One practical way to avoid money mistakes is to confirm authorization before scheduling care, even when a provider says they will handle the paperwork. An approval does not necessarily guarantee that every related charge is covered, so beneficiaries should also verify that the provider is in network and ask what they may owe out of pocket.
