How Long Does an Insurance Appeal Take? (2026 State-by-State Guide)

Written by the disputes.health team. Reviewed for accuracy.

Federal law requires insurers to respond to urgent (expedited) care appeals within 72 hours and standard appeals within 30 days. External appeals through an Independent Medical Review Organization must be decided within 45 days for standard cases and within 72 hours for urgent cases. Most states have additional protections that match or exceed federal timelines. If your insurer misses these deadlines, you have the right to file a complaint with your state insurance commissioner and escalate directly to external review without waiting.

Federal appeal timeline requirements

The Affordable Care Act sets minimum timelines for insurance appeal decisions that apply to all non-grandfathered health plans. For internal appeals: standard reviews must be decided within 30 days; urgent (expedited) reviews must be decided within 72 hours. For external reviews: standard external reviews must be decided within 45 days; urgent external reviews must be decided within 72 hours. These are the federal minimums — your plan or state may have faster requirements. The clock starts when the insurer receives your complete appeal package.

What counts as an "urgent" appeal

An appeal qualifies as urgent (expedited) when following the standard timeline would seriously jeopardize your health or your ability to regain maximum function. Examples include: ongoing inpatient care being denied, cancer treatment that cannot be delayed, medications for serious chronic conditions, mental health crises, and post-surgery care denials. Your doctor must certify the urgency in writing. If your doctor says it's urgent, the insurer must treat it as an expedited appeal.

Standard vs. urgent appeals — choosing the right track

Most routine denials go through standard review. But if your condition is serious, don't automatically accept standard timelines. A 30-day wait for a cancer treatment decision or a mental health inpatient authorization can cause real harm. Have your doctor write a sentence in the appeal letter or letter of medical necessity stating: "Given the clinical urgency of [patient]'s condition, I request that this appeal be processed on an expedited basis. Delay of [treatment] would [specific clinical consequence]." This triggers the 72-hour decision requirement.

State-by-state additional appeal protections

Many states have enacted appeal timelines stricter than federal requirements. California's Department of Managed Health Care requires Independent Medical Reviews within 30 days (not 45) for standard cases and within 3 days for urgent cases. New York's Department of Financial Services requires expedited appeals within 72 hours and has additional consumer advocate resources. Texas requires HMOs to decide standard utilization reviews within 3 business days and urgent reviews within 1 business day. Washington state requires prior authorization decisions within 3 business days for non-urgent and 1 business day for urgent requests. Check your state insurance commissioner's website for current requirements.

States with the fastest appeal requirements

California offers the fastest external review in the country through the DMHC — 30 days standard, 3 business days urgent, and the process is entirely free. New York provides a dedicated external appeal process through the New York State External Appeal Program that matches California's speed. Florida, Texas, and Illinois each have state-specific prior authorization reform laws enacted since 2020 that include stricter decision timelines for PA requests.

What happens if your insurer misses the decision deadline

If your insurer fails to decide your appeal within the required timeframe, you have several options: you can immediately request external review without waiting for the internal appeal decision, file a complaint with your state insurance commissioner for the deadline violation, and in some states, the deadline violation itself means the appeal is automatically decided in your favor. Document the deadline and date of your appeal submission carefully. If the insurer misses the deadline, send a letter noting the specific regulatory timeframe that was violated and your intent to escalate.

Medicare and Medicaid appeal timelines

Medicare appeals have different timelines than commercial insurance. For Medicare Advantage, internal reviews must be completed within 60 days for standard and 72 hours for expedited. For Medicare Part D drug denials, the standard review takes 7 days and expedited reviews take 72 hours. Medicaid timelines vary by state — generally 90 days to appeal with a decision within 90 days, though many states have shorter timelines. Medicare beneficiaries can also request a redetermination (the first level of Medicare appeal) within 120 days of a coverage denial.

Frequently asked questions

How long does an insurance company have to respond to an appeal?

Under the ACA, insurers must decide standard internal appeals within 30 days and urgent appeals within 72 hours. External independent reviews must be completed within 45 days for standard cases and 72 hours for urgent cases. Your plan may have faster requirements — check your Summary of Benefits and Coverage document.

What if my insurance company is taking longer than 30 days to decide my appeal?

File a complaint with your state insurance commissioner immediately. You also have the right to escalate to external review without waiting for the internal appeal decision if the insurer has exceeded the required timeframe. Document the date you submitted your appeal and the applicable deadline in your complaint.

Can I get an expedited (faster) appeal decision?

Yes, if your situation is medically urgent. Have your doctor certify in writing that following standard timelines would seriously jeopardize your health. The insurer must then process your appeal as expedited and decide within 72 hours. This applies to both internal appeals and external reviews.

How long does an external insurance appeal take?

External reviews through an Independent Medical Review Organization must be completed within 45 days for standard cases and 72 hours for urgent cases under federal law. California and New York have faster requirements — 30 days standard and 3 days urgent.

Does the clock restart if I add more documents to my appeal?

Adding documents after your initial appeal submission can reset the review clock, because the insurer may need to restart their review of the complete file. Submit all your documentation in one complete package to avoid this issue and to start the clock with your strongest case.
