Prior Authorization: What It Is, Why It Matters, and How to Navigate It

When your doctor prescribes a medication, but your insurance says prior authorization, a requirement by health insurers that doctors prove a medication is medically necessary before covering it. Also known as pre-authorization, it's a gatekeeping step that can delay treatment by days or weeks. You might think your doctor’s prescription is enough—turns out, it’s just the first step. Insurance companies use prior authorization to control costs, but it often ends up hurting patients who need meds right away.

Prior authorization isn’t random. It’s tied to specific drugs—usually expensive brand-name pills, new treatments, or ones with cheaper alternatives. If you’re on Medicare, Medicaid, or a private plan, you’ve likely run into this. It’s not just about cost. Insurers want proof that you tried cheaper options first, or that your condition meets strict criteria. For example, a drug for rheumatoid arthritis might need proof you failed at least two other meds before they’ll pay. The same goes for specialty drugs like those for multiple sclerosis or hepatitis C. And it’s not just medications—some medical devices, lab tests, and even therapy sessions require it too.

This process involves your doctor filling out forms, submitting records, and sometimes calling the insurer. But here’s the problem: most of the time, the burden falls on you. You get the call that your prescription was denied. You call your doctor’s office. They have to start over. You wait. Meanwhile, your pain doesn’t stop. Your symptoms get worse. Some people skip doses. Others give up entirely. It’s not just bureaucratic—it’s dangerous. Studies show delays in getting medications due to prior authorization can lead to hospitalizations, especially for chronic conditions like diabetes or heart disease. And it’s not just patients. Doctors spend hours on paperwork instead of care. Pharmacies get stuck in the middle. It’s a system that slows everything down.

But there are ways to fight back. Know which drugs in your plan need prior authorization. Ask your doctor to check before writing the script. Keep a list of all your meds and what’s been denied before. If it’s denied, appeal—most plans let you do that, and many approvals happen on appeal. Some states have laws limiting how long insurers can take to respond. And if you’re on Medicare, you have extra rights under Part D. You’re not powerless here.
