Your doctor’s office is responsible for obtaining prior authorization, not you. The process starts when your provider submits a request to your insurance company explaining why a specific treatment, procedure, or medication is medically necessary. Standard requests can take up to 30 days for a decision under current rules, though new federal regulations taking effect in 2026 will cap that at seven calendar days for non-urgent requests and 72 hours for urgent ones.
That said, you play a bigger role than most people realize. Understanding each step helps you track progress, catch delays, and push things forward when your care is on the line.
What Your Doctor’s Office Submits
When your provider initiates a prior authorization request, they send your insurance company a case for why the treatment is needed. This typically includes your diagnosis, relevant medical history, and supporting clinical documentation. For medications especially, insurers often want to see evidence that you’ve already tried and failed on cheaper or preferred alternatives. If you experienced serious side effects from a previous drug, or if a first-line treatment simply didn’t work, that history becomes part of the justification.
The specifics vary by insurer, but the core requirement is always the same: your doctor needs to demonstrate that the requested service is medically necessary for your situation. Incomplete or vague submissions are one of the most common reasons requests stall or get denied, so thorough documentation upfront matters enormously.
How the Review Works
Once the request is submitted, your insurance company reviews it against their coverage criteria. They may approve it outright, deny it, or come back asking for additional information. Both you and your provider receive the decision in writing.
If your doctor believes waiting could harm you, they can submit an expedited (urgent) request. Under new CMS rules finalized in 2024, insurers covering Medicare Advantage, Medicaid managed care, and certain marketplace plans must respond to urgent requests within 72 hours and standard requests within seven calendar days. These timelines represent a significant tightening from the previous 30-day window many plans used for standard requests. Private employer-sponsored plans may still operate under different timelines depending on your state.
Why Requests Get Denied
The most common reason for denial is that the insurer deems the treatment not medically necessary based on their own coverage guidelines. This doesn’t mean your doctor was wrong to recommend it. It means the insurance company’s reviewers, applying their internal criteria, decided the documentation didn’t meet their threshold. Sometimes the issue is genuinely clinical, but often it comes down to paperwork: missing records, incomplete treatment history, or failure to document that you tried the insurer’s preferred alternatives first.
A frustrating reality is that many denial letters are vague. Patients and providers may simply be told a medication “has not been granted prior authorization” with no further explanation. The American Medical Association has pushed for insurers to include a detailed explanation of the denial reason, links to the specific policy used in the decision, and clear guidance on what additional documentation could lead to approval. Some states now require this level of transparency, but many do not.
How Electronic Systems Speed Things Up
Prior authorization has historically run on faxes and phone calls, which created bottlenecks and errors. Electronic prior authorization (ePA) systems are changing that. A 2021 study from America’s Health Insurance Plans found that the median time from submission to decision dropped 69% with electronic processing, falling from 18.7 hours to 5.7 hours. Practices using ePA also saw denials due to missing information drop by 68% and appeals decrease by 88%, largely because the electronic forms flag incomplete fields before submission.
Not every provider office or insurer has adopted ePA yet, but adoption is growing. If your provider still uses fax-based submissions, it’s worth knowing that delays are more likely and errors from illegible or incomplete paperwork are common.
What You Can Do as a Patient
Even though your doctor’s office handles the submission, you can take several concrete steps to keep things moving:
- Alert your doctor’s office immediately if a pharmacy flags an issue. If you show up to pick up a prescription and learn it requires prior authorization, make sure the pharmacy notifies your provider so they can start the process. Don’t assume this communication happens automatically.
- Follow up regularly. Call your doctor’s office to check on the status of the request. Staff are juggling dozens of authorizations at any given time, and a polite check-in can surface a request that got stuck or a fax that never went through.
- Call your insurance company directly. You have every right to call the number on your insurance card and ask about the status of a pending authorization. The representative can tell you whether the request was received, whether additional documentation has been requested, and when a decision is expected.
- Keep your own records. Note the dates of submissions, the names of people you speak with, and any reference numbers. If you end up needing to appeal, this timeline becomes valuable.
How to Appeal a Denial
If your request is denied, you have two levels of appeal available. The first is an internal appeal, where you ask your insurance company to reconsider its own decision. You, a family member, or your healthcare provider can file this on your behalf. During the internal appeal, a different reviewer at the insurance company examines the case, often with additional documentation your doctor provides. Many providers will also request a peer-to-peer review, which is a direct phone conversation between your doctor and the insurer’s medical reviewer to discuss the clinical reasoning.
If the internal appeal is also denied, you have the right to an external review. This sends your case to an Independent Review Organization (IRO), a neutral third party that is not affiliated with your insurance company. The IRO makes its decision based on medical evidence, and its ruling is typically binding on the insurer. Your denial letter should include instructions on how to initiate both types of appeals and the deadlines for filing.
Appeals are worth pursuing. Many initial denials are overturned, particularly when the doctor provides stronger documentation or when the original denial was based on incomplete information.
Gold Card Exemptions in Some States
Several states have passed laws that exempt high-performing providers from prior authorization requirements altogether, a concept known as “gold carding.” The idea is straightforward: if a doctor consistently gets approved, requiring them to submit authorization requests wastes everyone’s time.
Texas and Arkansas both use a 90% approval threshold. In Texas, if a provider receives approval on at least 90% of prior authorization requests for a specific service over a six-month period, the insurer must exempt them from prior authorization for that service. West Virginia has a similar structure but adds a volume requirement of at least 30 procedures per year, and the exemption lasts six months before review. Louisiana and Michigan require insurers to maintain programs that reduce prior authorization burdens based on provider performance, though the specific criteria are left more to the plans’ discretion.
If you live in one of these states, your provider may already be exempt from prior authorization for certain services without you knowing. It’s worth asking your doctor’s office whether they qualify, especially if you’re facing a time-sensitive treatment decision.
