What the OTC Benefit Covers

The OTC benefit covers products you can buy without a prescription:

What Part D Covers

Part D covers prescription medications ordered by your doctor:

Common Mistakes to Avoid

Mistake 1: Buying OTC products at the pharmacy

If you're buying Tylenol, vitamins, or allergy medicine at the drugstore with your own money, check if your OTC benefit covers it first. You might be paying for products you can get free.

Mistake 2: Thinking you need a prescription for OTC items

You do NOT need a doctor's prescription to use your OTC benefit. You simply choose products from the approved catalog and order.

Mistake 3: Letting the quarter expire

Your OTC allowance resets every 3 months and does not roll over. Set a reminder to use it before each quarterly deadline.

Pro tip: Even if you're healthy and don't think you need supplements, order basic items like a thermometer, first aid kit, and multivitamins. These are products every household should have — and they're free.

How to Maximize Both Benefits

  1. Use your OTC benefit for daily health products (vitamins, pain relief, first aid)
  2. Use Part D for prescription medications from your doctor
  3. Order OTC quarterly — don't let free money expire
  4. Check both when your doctor recommends something — it might be covered under OTC instead of requiring a prescription
