Prior authorization explained — fighting insurance denials for medications

Reviewed by a healthcare policy and patient advocacy contributor

Prior authorization is the process insurance companies use to approve or deny coverage of certain medications before they will pay, and according to an AMA survey, 94 percent of physicians report that prior authorization delays necessary care. When your parent's doctor prescribes a medication and insurance says no, that is not the end of the conversation. The denial can be appealed, and appeals succeed more often than families realize.

Insurance Did Not Get the Last Word — the Doctor Does

Your mother's doctor prescribed a newer arthritis medication. Research supports it for her specific situation. Insurance denied coverage and wants her to try cheaper medications first. Now there is an argument between her doctor and her insurance company about what medicine she should take, and your mother is caught in the middle without the medication she needs.

This is prior authorization, and it is one of the most frustrating parts of the healthcare system. Before paying for certain medications, insurance companies require the prescribing doctor to submit documentation proving the medication is medically necessary. For some drugs, they require evidence that cheaper alternatives were tried first and failed. The process is designed to control costs. It also delays treatment, creates enormous administrative burden, and according to AHRQ research, contributes to worse health outcomes when patients go without needed medications during the review period.

Understanding the mechanics helps you fight back. When a prescription is submitted and insurance requests prior authorization, they are not denying the medication outright. They are asking for justification. The doctor's office submits documentation including medical records, lab results, notes on previously failed treatments, and a letter explaining why this specific medication is necessary for this specific patient.

Step Therapy and the Fail-First Problem

The most common trigger for prior authorization is cost. A newer, more expensive medication requires approval; its generic predecessor does not. Insurance may be willing to pay, but wants proof the expense is warranted.

Step therapy, sometimes called fail-first, is a specific version of this. Insurance requires your parent to try a cheaper medication before they will cover the prescribed one. Only after that medication demonstrably fails can your parent access what the doctor originally ordered. This makes financial sense for the insurer, but it means your parent may spend weeks or months on an ineffective drug while the paperwork catches up to what the doctor already knew.

The timeline is the urgent part. Prior authorization takes days to weeks. During that time, your parent is without the medication. Your role is to follow up aggressively. Call the doctor's office and ask about status. Call the pharmacy to check whether authorization has come through. Call the insurance company and ask what information they still need. The AMA reports that the average prior authorization takes one to two business days to process, but complex cases or incomplete submissions can take much longer.

How to Appeal and Win

If the initial request is denied, the doctor can appeal. If insurance wants step therapy and the doctor disagrees, the doctor can argue against it. The doctor can submit studies showing why the prescribed medication is better for your parent's condition. They can document adverse reactions your parent had to the cheaper alternatives. They can explain why the standard protocol does not apply in this case.

Some insurance companies allow multiple levels of appeal. Each level goes to different reviewers who may assess the case differently. The doctor's office handles the medical arguments, but you keep the pressure on by checking in every few days, letting them know this matters, and asking for updates.

Some doctor's offices are better at this than others. Larger practices often have dedicated staff for prior authorizations. Smaller practices may find the paperwork tedious and move slowly. If the office seems to be dragging, politely but persistently remind them that your parent is waiting.

While waiting for authorization, your parent may need the medication urgently. In that case, paying out of pocket while the appeal is processed is sometimes an option. If the authorization is later approved, some insurance companies will reimburse what was paid. Some will not. Discuss this with both the doctor and pharmacy before committing.

Pharmacy staff are valuable allies in this process. Pharmacists know the insurance system well and can often predict whether an authorization will go through. They may suggest a covered alternative that works while the appeal plays out. They can contact the insurance company directly. Building a relationship with your parent's pharmacist pays off here.

When to Escalate

If the appeals process is exhausted and you believe the denial is wrong, state insurance commissioners accept complaints. Filing with your state's department of insurance is a last resort, but it exists and companies take these complaints seriously.

Prevention also matters. At the start of each year, when formularies change and plans reset, ask the doctor which of your parent's medications might face prior authorization requirements. Getting authorizations in place before the prescriptions are needed avoids the crisis of running out while waiting for approval.

Your parent's own voice carries weight too. They can call insurance and explain how the denial affects their health. They can ask their doctor to call the insurance medical director directly. According to CMS data, external review of denied claims overturns the original decision in roughly 40 to 60 percent of cases, depending on the state and type of review. The system assumes most people will accept the first no. Do not be one of them.

Frequently Asked Questions

What is prior authorization?
It is a process where insurance requires the doctor to justify a medication before they will pay for it. The doctor submits documentation, and insurance decides whether to approve or deny coverage.

How long does prior authorization take?
Typically one to five business days for straightforward cases. Complex cases or incomplete submissions can take longer. Urgent requests can sometimes be expedited if the doctor's office flags them.

Can my parent get the medication while waiting for authorization?
Sometimes. The doctor may have samples, the pharmacy may offer a short bridge supply, or your parent can pay out of pocket and seek reimbursement later if the authorization is approved.

What if the appeal is denied?
Most insurance plans allow multiple levels of appeal. If internal appeals are exhausted, an external review by an independent third party is available in most states. Filing a complaint with the state insurance commissioner is another option.

Is prior authorization the same as a denial?
No. A prior authorization request means insurance wants more information before deciding. A denial is a decision not to cover. Both can be challenged.

What can I do to help speed things up?
Call the doctor's office, pharmacy, and insurance company regularly. Ask for specific status updates. Make sure the doctor's office has submitted all required documentation. Be the squeaky wheel.
