Approved, Yet Stuck: Untangling the Prior Authorization Delays Keeping Patients Waiting

The scenario is familiar to a growing number of American patients: a physician prescribes a medication, confirms the insurance plan covers it, and sends it to the pharmacy. Hours later — sometimes days — the patient receives a call. The claim is on hold. The insurer requires something called prior authorization before it will pay.

Nothing about the prescription has changed. The doctor still believes the drug is appropriate. The plan still lists it as covered. Yet the medication sits in limbo while paperwork moves through a process most patients have never heard of until it delays their own care.

What Prior Authorization Actually Is

Prior authorization (PA) is a utilization-management tool: a requirement that a health plan review and approve certain prescriptions before dispensing. The stated purpose is to ensure the medication is medically necessary, used appropriately, and — notably — not more expensive than a preferred alternative.

In practice, the process works like this. A prescriber or pharmacy submits a request to the insurer, often through a portal or fax, including the diagnosis, prior treatments tried, and clinical justification. A plan representative — sometimes a pharmacist, sometimes not — reviews the submission against the plan's own criteria. Approval, denial, or a request for more information follows.

Research published in the Journal of the American Medical Association found that physicians' practices complete roughly 40 prior authorizations per week on average, consuming the equivalent of nearly two full staff days. The American Medical Association's recurring surveys consistently report that a substantial share of PA requests are eventually approved — suggesting the process functions, in many cases, less as a clinical gate than as a cost-control filter.

Which Prescriptions Get Caught

Prior authorization is not applied uniformly. Certain drug classes trigger it far more often than others:

• Specialty medications, including biologics and drugs for rheumatoid arthritis, multiple sclerosis, and certain cancers
• Brand-name drugs with lower-cost equivalents, where plans push patients toward generics or biosimilars first
• Newer medications recently brought to market, whose long-term cost profiles plans are still assessing
• Certain controlled substances and sedatives, where safety review is a stated concern
• Drugs for weight management and ADHD, two categories that have seen sharply rising demand and correspondingly aggressive PA requirements

Step therapy — a related tactic requiring patients to try and fail on cheaper alternatives first — often compounds the delay.

Who the System Serves

Insurers contend that prior authorization controls premiums by curbing unnecessary spending, and there is no dispute that prescription drug costs shape what plans charge employers and members. Patient advocates and physician groups counter that the burden falls heavily on the people least equipped to bear it: those waiting for treatment. When a PA delay stretches from days into weeks, the practical consequence is a patient going without a medication their doctor already deemed necessary.

The honest answer is that the system serves cost containment first and clinical timeliness second — and patients who understand this are better positioned to navigate it.

What Patients Can Do

Prior authorization delays cannot always be prevented, but they can often be shortened.

Ask at the point of prescribing. Before leaving the doctor's office, ask directly: "Will this require prior authorization on my plan?" If yes, ask whether the practice will submit the request that day.

Request the expedited path. Standard PA reviews may take up to 14 days under Medicare Advantage rules; expedited reviews, reserved for situations where delay could harm the patient, are typically resolved within 72 hours. Patients and prescribers can request expedited review when clinically warranted — and it is worth asking for explicitly.

Check for alternatives. Sometimes a therapeutically similar medication without a PA requirement can be dispensed immediately while the authorization proceeds in the background. Pharmacists are often the fastest source of this information, since they see which claims clear and which stall.

Follow the paper trail. If a PA request is denied, patients have appeal rights — including an external review in many cases. Denials for incomplete documentation, rather than outright clinical refusals, are common and frequently reversed on resubmission.

Use the pharmacy as an ally. Pharmacy staff track PA statuses daily and can often flag exactly where a request sits and what the insurer needs to move it forward.

The Takeaway

Prior authorization exists because American health plans are managing drug spending in a system with few other cost controls. Patients cannot opt out of it, but they can prepare for it — by asking the right questions before the prescription is sent, knowing their right to expedited review, and treating the pharmacy team as a working partner in untangling the delay. A prescription that is approved but stuck is not a lost cause. It is a process, and processes can be moved.
