Starting in 2026: Faster Prior Authorization Timelines—What Families Should Do If Care Is Delayed

Prior authorization is that extra step some health plans require before they cover certain prescriptions, therapies, procedures, or medical services. When the plan takes too long to decide, it can affect everyday care—missed appointments, prolonged symptoms, or delays in starting treatment.

Starting in 2026, new CMS requirements for many “impacted payers” are designed to make those decisions faster and the reasons for denials more understandable. Here’s what the “clock” means and what families can do if care is delayed.

What’s changing in 2026 (and who it applies to)

CMS’s prior authorization rules set decision timeframes for many “impacted payers,” a term CMS uses to describe certain insurance types subject to the federal requirements (for example, many Medicare Advantage and Medicaid/CHIP managed care arrangements, and other covered plan types depending on how CMS defines the category).

CMS also requires greater denial transparency for many medical-item/service prior authorizations—aiming to reduce guesswork for clinicians and families. CMS describes compliance dates beginning Jan. 1, 2026, with operational rollout that can vary by payer.

The “clock” in plain language: 72 hours vs. 7 calendar days

Under the CMS requirements described for 2026, the timeline depends on whether the request is treated as urgent (expedited) or routine (standard):

Expedited (urgent) requests: decision within 72 hours
Standard (non-urgent) requests: decision within 7 calendar days

Because prior authorization processes can differ across plans and benefit designs, the safest approach is to confirm with your clinician’s office what they submitted (expedited vs. standard) and to track the dates.

Denial reasons: why more detail can help families move faster

When a prior authorization is denied without a clear explanation, clinicians may need to resubmit with different documentation, or families may have to wait while paperwork gets sorted out. CMS’s transparency goal is to provide a specific reason for denials for many medical-item/service requests, so the next step is clearer.

Research also suggests that prior authorization can create extra administrative burden for patients and caregivers, with associations reported between prior authorization experiences and care delays or difficulty receiving care as recommended.

What to do while you’re waiting for approval

If your family is waiting on a prior authorization decision, these practical steps can help:

Confirm how it was submitted: Ask the clinician’s office whether the request was sent as expedited/urgent or standard/non-urgent.
Ask whether the request is complete: Incomplete information can stall decisions. Ask what documents were included and whether anything is missing.
Track the dates: Note when the request was submitted and when you follow up. The CMS timeframes are measured in hours/days.
Check the status early: Contact the clinician’s office and the plan (member services) to ask whether the request is pending review, pending more information, or already decided.
If denied, request the specific reason: Ask your clinician’s office to obtain the denial reason so they can address it appropriately.
Ask about the next step: Your provider can explain what happens after a denial for that plan type (which may involve resubmission and/or an appeal, depending on the situation).

When delays may be dangerous—seek urgent or emergency care

Prior authorization timelines are meant to reduce delays, but they do not replace medical decision-making when symptoms are serious. If your situation feels medically urgent—such as severe symptoms, rapidly worsening conditions, or emergency warning signs—seek urgent care or emergency services as appropriate.

What’s still uncertain

Scope can vary: CMS rules apply to defined “impacted payers,” and how prior authorization shows up in your day-to-day care can depend on your specific plan and benefits.
Real-world implementation varies: CMS describes electronic and process improvements, but performance can differ across organizations.
Drug prior authorization may follow different requirements: CMS notes that drug prior authorization can involve different policy details than some medical-item/service requirements, so ask your clinician’s office what rules apply to your specific request.

Bottom line

Beginning in 2026, many families should see faster prior authorization decisions for medical items and services—with 72 hours for expedited (urgent) requests and 7 calendar days for standard (non-urgent) requests—plus requirements intended to make denials more actionable.

If care is delayed, confirm whether the request was expedited or standard, track the dates, and ask for the denial reason so your clinician can move to the next appropriate step.
