Your doctor just told you the scan needs prior authorization, and as of January 1, 2026, your insurer has as little as 72 hours to decide. That approval isn’t automatic and it isn’t instant, but most insurers are now on a real clock to answer, and knowing exactly how many hours are on it changes what you do next.

The first 24 hours after the diagnosis

Prior authorization means your insurer wants to review the request before it pays for the scan, procedure, or medication your doctor ordered. Your doctor’s office submits the request, usually electronically, and marks it either “standard” or “urgent.” That single word decides how many days you wait.

Call your doctor’s office the same day and ask three things: was the request marked urgent, what date and time was it submitted, and who is the point of contact tracking it. Write down the answers. If your condition is genuinely time-sensitive, either the medical exigency itself or your doctor’s judgment can justify marking it urgent, and your plan is required to treat that designation seriously.

What activates the moment the request is submitted

A federal rule called the CMS Interoperability and Prior Authorization Final Rule, known as CMS-0057-F, took effect for most of its decision-timeline requirements on January 1, 2026. It requires Medicare Advantage plans, state Medicaid programs, Medicaid managed care plans, and CHIP managed care plans to decide urgent prior authorization requests within 72 hours and standard requests within 7 calendar days.

One important exception: the rule’s own text specifically excludes Marketplace plans sold through the federal exchange, healthcare.gov, from this particular deadline requirement. If your coverage came from a state-run marketplace, call your plan directly and ask what internal timeline it commits to, because the federal 72-hour and 7-day clock does not automatically apply.

If your coverage is an employer-sponsored plan that pays claims itself rather than buying insurance (a “self-funded” plan), a different federal rule already covers you and has for years. Under the Employee Retirement Income Security Act (ERISA), 29 CFR 2560.503-1 covers you instead. It requires a decision on an urgent care claim “as soon as possible,” no later than 72 hours after receipt. The same 72-hour standard applies again if you appeal a denial on an urgent basis.

If you’re still waiting on test results or a treatment plan from the hospitalization itself, the first days of the crisis carry their own separate deadlines. See what to do in the first 72 hours after a hospitalization.

If your treatment is already underway and your insurer wants to reduce or stop it, that is treated as its own kind of denial under the same ERISA rule. The plan has to notify you far enough in advance of the cutoff date that you have a real chance to appeal and get a decision before the treatment actually stops, not after.

Your plan type	Standard decision deadline	Urgent decision deadline
Medicare Advantage	7 calendar days	72 hours
Medicaid or CHIP managed care	7 calendar days	72 hours
Employer self-funded plan (ERISA)	15 days (non-urgent, pre-service)	72 hours
Marketplace plan via healthcare.gov	Not set by CMS-0057-F; ask your plan directly	Not set by CMS-0057-F; ask your plan directly

The mistake that costs people their treatment window

This is the mistake that costs people weeks they don’t have: assuming the clock automatically means an automatic approval if the insurer goes silent. It doesn’t. There is no federal rule that deems your request approved just because your insurer blows past 72 hours or 7 days. What the new rule actually does is force insurers to publicly report their own timeliness numbers starting in 2026, which is an accountability tool, not a same-day fix for you.

So if the deadline passes with no answer, don’t wait quietly for one. Call your insurer, cite the exact submission date, and ask for the decision in writing that day. If you’re in Texas, there’s a second lever available to you. Texas Insurance Code section 4201.206 requires the insurer’s review agent to offer your doctor a peer-to-peer discussion before it can issue a denial. That discussion must be with a Texas-licensed physician in the same or a similar specialty. If your doctor hasn’t been offered that call yet and you’re covered under a Texas-regulated plan, ask for it explicitly before the denial becomes final. This specific right has not been confirmed in other states. If you live outside Texas, don’t assume it applies; ask your plan directly whether it offers a peer-to-peer option.

If your insurer says no

A denial is not the end of the process, and for an urgent situation you don’t have to pick one appeal path over another. Two tracks are available to you at the same time.

The first is an expedited internal appeal with your own plan, which under the same ERISA rule must be decided within 72 hours of your request for review. The second is an expedited external review by an independent review organization that has no relationship to your insurer. Federal rule 45 CFR 147.136 lets you file for expedited external review the moment you receive an adverse decision involving a medical condition that would seriously jeopardize your life or health. The independent reviewer must decide within 72 hours of receiving your request. This runs in parallel with your internal appeal, not after it finishes.

If your appeal is about a hospital claim rather than a pre-treatment authorization, the deadlines run differently; see the appeal windows after an insurer denies a hospital claim for that specific timeline.

Check your insurer’s denial letter for the specific form and contact information for both appeal types. Every denial letter is required to explain how to request each one; if yours doesn’t, call the number on your insurance card and ask directly.

What to do at 30, 60, and 90 days

At 30 days, if your appeal is still open, request a written status update from both your plan and the independent review organization. Keep a copy of every fax confirmation, portal screenshot, and call log. At 60 days, if you’re still waiting on a final answer and your treatment has been delayed the entire time, ask your doctor’s office whether the delay itself now qualifies as a new urgent situation. A treatment that was merely time-sensitive at diagnosis can become genuinely urgent once it’s been stalled for two months, and that new urgency can reset the clock. At 90 days, if your treatment still hasn’t started, most state insurance departments allow you to file a formal complaint against the plan directly, separate from the appeal process. That complaint creates a paper trail that can speed up everything still pending.

If this treatment is expected to keep you out of work for months, not weeks, the two disability clocks that do not run in sequence covers why your Social Security Disability Insurance application needs to start now, not after short-term benefits end.

Frequently asked questions

What if my treatment is urgent but my prior authorization is still pending? Ask your doctor to confirm in writing that the request was marked urgent and note the exact submission date. Under CMS-0057-F, Medicare Advantage, Medicaid, and CHIP managed care plans must decide urgent requests within 72 hours; self-funded ERISA plans follow the same standard. Ongoing treatment cannot be cut off without advance notice.

Does the 72-hour rule apply to my ACA marketplace plan? Not automatically. CMS-0057-F specifically excludes plans sold through healthcare.gov from its 72-hour and 7-day deadline. Call your plan directly and ask what internal decision timeline it follows, since the federal clock described here does not bind it.

Can I ask for a peer-to-peer review outside Texas? Texas Insurance Code section 4201.206 is the only state peer-to-peer requirement confirmed here, and it applies to Texas-regulated plans. Some insurers offer this voluntarily elsewhere, but it isn’t a confirmed right nationwide. Ask your plan directly.

What happens if my insurer misses the deadline? Your request is not automatically approved; no federal rule deems a missed deadline an approval. Call your insurer immediately, cite the missed deadline in writing, and demand a decision. You can also file a complaint with your state insurance department if the delay continues.

Can I keep getting treatment while I appeal a denial? If your plan wants to reduce or stop treatment you’re already receiving, federal rule requires advance notice so you can appeal and get a decision before treatment actually stops. Ask your plan in writing to confirm your current treatment continues during that window.
