The short answer

Prior authorization means the plan wants to review and approve a medication before they'll cover it. You, your doctor, or the pharmacy can start that process.

The full explanation

Prior authorization, often shortened to PA, is a step some Part D plans require before they'll pay for certain medications. It's not a denial. It's the plan saying they want more information first, usually to confirm the drug is appropriate for your diagnosis or that other treatments were tried first.Your doctor's office typically handles this. They submit clinical notes or a letter of medical necessity to the plan. The plan is required to respond within a specific window, usually 72 hours for a standard request, or 24 hours if your doctor requests an expedited review because waiting would harm your health.If the prior authorization is denied, you have the right to appeal. Your doctor can submit additional documentation, and the appeal goes to an independent reviewer if the plan upholds the denial. This process has real teeth, and doctors who advocate strongly for their patients often see approvals on appeal.While you're waiting, ask your doctor if samples are available, or whether a short-term supply can be obtained some other way. Some manufacturers also have patient assistance programs for brand-name drugs.It's also worth knowing that some medications require prior authorization every year, even if it was approved before. Check at the start of each plan year to avoid a surprise gap in coverage. Details vary by plan, so always confirm the current requirements directly with your insurer.

In 

Ohio

 specifically

Ohio beneficiaries should pay close attention to local hospital systems and doctor networks before enrolling, because plan availability does not guarantee your preferred providers are in network. Ohio residents can also get free Medicare counseling through the Ohio Senior Health Insurance Information Program.

What this means for you

For you, this means your doctor's office does most of the heavy lifting on prior authorization, but staying in close contact with them and the pharmacy helps things move faster.
