Medicare Part D does not cover Zegerid OTC, but your coverage for heartburn relief depends on which plan you have and what form of the medication your doctor prescribes.
Zegerid OTC is an over-the-counter heartburn medication that combines omeprazole (a proton pump inhibitor) with sodium bicarbonate. Because it is sold without a prescription, Medicare Part D plans do not cover it. However, if your doctor prescribes the prescription version of omeprazole or a different heartburn medication, your Part D plan may cover that instead — and it could cost you less than buying Zegerid OTC out of pocket.
The key difference is between what you buy at the pharmacy shelf and what your doctor writes on a prescription pad. Medicare Part D covers prescription medications but not over-the-counter drugs, even if they contain the same active ingredient as a prescription version.
Key Takeaways
- Zegerid OTC is not covered by Medicare Part D because it is sold without a prescription.
- If your doctor prescribes omeprazole or another heartburn medication, your Part D plan may cover it, often at a lower cost than buying Zegerid OTC yourself.
- You can ask your doctor to write a prescription for omeprazole instead of using the over-the-counter version.
- Your out-of-pocket cost for a prescription heartburn medication depends on your specific Part D plan and which tier the drug is on.
- Some people find that a prescription is cheaper than repeatedly buying Zegerid OTC, especially if they take it daily.
Why Medicare Part D Does Not Cover Over-the-Counter Medications
Medicare Part D is designed to cover prescription drugs — medications that require a doctor's order and a pharmacist's dispensing. Over-the-counter medications, including Zegerid OTC, fall outside this coverage because they are available without a prescription. This is true even when the over-the-counter version contains the same active ingredient as a prescription drug.
The distinction matters because it affects what you pay. When you buy Zegerid OTC at a drugstore, you pay the full retail price out of your own pocket. Medicare does not reimburse you for any part of it. If you instead use a prescription version covered by your Part D plan, you typically pay only a copay or coinsurance amount, which is often much less than the retail price.
How to Get Prescription Coverage for Heartburn Relief
If you currently take Zegerid OTC and want to see whether a prescription alternative might be covered, start by talking to your doctor. Tell them you are taking Zegerid OTC and ask whether they would prescribe omeprazole or another heartburn medication instead. Most doctors can write this prescription during a regular visit or over the phone.
Once you have a prescription, take it to your pharmacy and ask the pharmacist to check your Part D coverage. The pharmacist can tell you which tier the medication is on and what your copay will be. You can also call your Part D plan directly — the phone number is on your insurance card — and ask about coverage for specific heartburn medications before you fill a prescription.
Keep in mind that some Part D plans cover certain heartburn medications but not others. Your plan's formulary (the list of covered drugs) determines what is available to you. If your doctor's first choice is not covered, the plan may cover a different heartburn medication, or your doctor may be able to request an exception.
Comparing the Cost of Zegerid OTC to Prescription Alternatives
The price of Zegerid OTC varies by retailer and package size, but a month's supply typically costs between $15 and $30 if you buy it regularly at a drugstore. If you take heartburn medication every day, this adds up quickly over a year.
A prescription omeprazole covered by Medicare Part D usually costs $5 to $15 per month in copays, depending on your plan and the tier the drug is on. For many people, especially those who take heartburn medication daily, a prescription is significantly cheaper than buying Zegerid OTC repeatedly.
However, if you only take heartburn medication occasionally — a few times a month — buying Zegerid OTC might be less expensive than paying a copay each time you fill a prescription. Calculate your own situation: multiply your monthly Zegerid OTC cost by 12, then compare that to the annual copay cost of a prescription alternative.
What Happens If Your Doctor Prescribes Omeprazole
If your doctor prescribes omeprazole or another heartburn medication, your Part D plan will cover it according to your plan's rules. You will pay a copay at the pharmacy, and the rest of the cost is covered by Medicare (up to the plan's limits). The copay amount depends on which tier the medication is on — typically tier 1 (generic) medications have the lowest copay, and tier 3 or 4 (brand-name) medications have higher copays.
Your Part D plan also has an annual deductible, which you must meet before the plan starts paying for most drugs. Once you meet the deductible, you pay your copay for each prescription. Later in the year, if your total drug costs reach a certain amount, you may enter the "coverage gap" (also called the "donut hole"), where you pay a higher percentage of the cost. Understanding where you are in your plan's year can help you predict what you will owe.
Other Heartburn Medications Medicare Part D May Cover
Omeprazole is not the only heartburn medication available by prescription. Your Part D plan may also cover other proton pump inhibitors (such as pantoprazole, lansoprazole, or esomeprazole) or H2 blockers (such as famotidine or ranitidine). These medications work differently and may be better suited to your situation depending on how often you need relief and how severe your symptoms are.
Your doctor can help you choose which medication might work best for you, and your pharmacist can tell you which options are covered by your plan. If your doctor's first choice is not covered, ask whether a covered alternative would work for your condition.
Questions to Ask Your Doctor and Pharmacist
Before you switch from Zegerid OTC to a prescription, gather information that will help you make the right choice. Ask your doctor whether a prescription heartburn medication would be appropriate for you, and if so, which one they recommend. Ask your pharmacist what your copay would be for that medication and whether your Part D plan covers it. You can also ask whether there are other covered options if your doctor's first choice is expensive.
If you are currently taking Zegerid OTC and it is working well for you, let your doctor know that before they prescribe something different. Your doctor may be able to prescribe omeprazole in the same dose and form you are already using, which means you should not notice any change in how the medication works.
When to Contact Medicare or Your Part D Plan
If you have questions about what your specific Part D plan covers, call the plan directly. The phone number is on your insurance card, and you can also find it on Medicare.gov. Have your plan name and member ID ready when you call. A representative can tell you whether a specific medication is covered, what tier it is on, and what your copay will be.
If you believe a medication should be covered but your plan has denied it, you have the right to request an exception. Your doctor can submit this request on your behalf, explaining why the medication is medically necessary for you. The process takes a few days to a few weeks, and your plan must notify you of the decision in writing.
Frequently Asked Questions
Can I use my HSA or FSA to buy Zegerid OTC if Medicare does not cover it?
Yes. If you have a Health Savings Account (HSA) or Flexible Spending Account (FSA), you can use those funds to buy over-the-counter heartburn medications, including Zegerid OTC. These accounts allow you to set aside pre-tax money for medical expenses, which includes over-the-counter drugs. Keep your receipt in case you need to document the purchase.
If I take Zegerid OTC now, will switching to a prescription medication change how well it works?
Not necessarily. If your doctor prescribes omeprazole — the same active ingredient in Zegerid OTC — at the same dose, you should experience the same relief. Your doctor can prescribe omeprazole in the same strength you are currently taking, so the switch should be seamless. If your doctor recommends a different medication, discuss any concerns about effectiveness before you fill the prescription.
What if my Part D plan does not cover any heartburn medications?
Some Part D plans have limited coverage for heartburn medications, though most cover at least one option. If your plan does not cover the medication your doctor recommends, ask your doctor about other options that might be covered. You can also request an exception from your plan if your doctor believes a specific medication is medically necessary. If no prescription option is covered, you would continue buying Zegerid OTC out of pocket.
Do I need a new prescription every time I refill my heartburn medication?
No. Once your doctor writes a prescription for omeprazole or another heartburn medication, you can usually refill it multiple times without getting a new prescription. Most prescriptions allow for several refills. Your pharmacist can tell you how many refills are authorized and when you will need to contact your doctor for a new prescription.
Will my copay for a heartburn medication change during the year?
Yes, it may. Your copay depends on where you are in your Part D plan's coverage year. Early in the year, you pay toward your deductible. Once you meet it, you pay your regular copay. Later in the year, if your total drug costs reach a certain threshold, you enter the coverage gap, where you pay a higher percentage. Your copay may also change if you switch to a different Part D plan during the annual enrollment period.
