Insurance Approval: What You Need to Know Before You Start

When you need a prescription, insurance approval, the process where your health plan reviews and agrees to cover a medication before you can get it. Also known as prior authorization, it’s not a delay tactic—it’s a system meant to control costs and ensure you get the right treatment. But for patients, it often feels like a maze. Many people don’t realize that even if a drug is on their plan’s list, it might still need approval. That’s because insurers often require proof that cheaper or safer options were tried first, or that the condition matches their strict guidelines.

This process affects everything from prescription insurance, the coverage your plan provides for medications to how quickly you can start treatment. For example, if your doctor prescribes a newer statin like simvastatin at high doses, or a complex immunosuppressant like tacrolimus, your insurer may demand lab results or documentation before approving it. The same goes for drugs like lisinopril during pregnancy, or domperidone for nausea—many insurers list them as restricted unless specific criteria are met. prior authorization, a step required by insurers before covering certain drugs isn’t just paperwork. It’s a gatekeeper that can delay care by days or weeks.

Why does this happen? Because insurers use formularies—lists of approved drugs—and they change often. A drug you got last year might now need prior authorization, or be moved to a higher tier with a bigger copay. Even generic versions like Etodolac, a common NSAID used for pain and inflammation can be affected if your plan has a preferred alternative. And if you’re trying to buy something like tetracycline online to save money, you might be skipping the approval process entirely—and risking fake or unsafe products.

It’s not just about cost. Insurance approval is tied to safety. If you’re on blood thinners and experience bleeding, your insurer might require you to use a specific DOAC over warfarin based on clinical guidelines. Or if you have celiac disease and need acid reflux meds, they might block ranitidine (which is no longer sold anyway) and only cover famotidine. Even medication adherence, how consistently patients take their prescribed drugs is influenced by whether the drug is approved and affordable. If you can’t get your medicine fast, you might skip doses—or stop entirely.

So what can you do? Talk to your pharmacist. They know the insurer’s rules better than most doctors. Ask your provider to submit documentation upfront—lab results, diagnosis codes, even a letter explaining why the drug is necessary. Keep records. If your approval is denied, you have the right to appeal. Many people don’t know this, but over half of appeals get approved on the first try.
