D0108/fm is a dental code Medicare uses to describe a specific type of tooth cleaning

The code D0108/fm refers to a prophylaxis (cleaning) for a child — the "fm" means it was done using fluoride mouth rinse as part of the cleaning. Medicare itself does not cover routine dental work, including cleanings, for most seniors. However, you may see this code on a claim if you have a dental plan through Medicare Advantage, or if you received this service at a hospital or outpatient facility where Medicare paid for it as part of treatment for another condition.

The "D" prefix means this is a dental procedure code from the American Dental Association's standard coding system. Medicare and dental insurers use these codes to describe what was done, how much it cost, and who should pay. Understanding what the code means helps you read your explanation of benefits and spot billing errors.

Key Takeaways

  • D0108/fm is a dental cleaning code for children that includes fluoride rinse, not a service Medicare typically covers for seniors.
  • If you see this code on a Medicare claim, it usually means either a dental plan through Medicare Advantage paid for it, or a hospital billed it as part of another covered service.
  • The code itself does not tell you whether Medicare or your plan paid — you need to check the "who paid" column on your explanation of benefits.
  • Routine dental cleanings are not covered by Original Medicare Part A or Part B, even if you see a code on your claim.

Why this code appears on Medicare claims

You may see D0108/fm on a claim for several reasons. If you have a Medicare Advantage plan (Part C), many of these plans include dental benefits, and your plan may have paid for a cleaning. If you received dental work at a hospital or outpatient surgery center as part of treatment for a medical condition — for example, cleaning before oral surgery — Medicare may have paid for the cleaning as part of the hospital bill.

Less commonly, you might see this code if a dentist's office submitted a claim to Medicare by mistake, or if you have a secondary dental plan that uses this code to track what was done. The code itself does not mean Medicare paid; you have to look at the explanation of benefits to see who actually covered the cost.

How to read your claim when you see this code

When you receive an explanation of benefits, look for these columns: the procedure code (D0108/fm), the date of service, the amount the provider charged, and the amount your plan or Medicare paid. If the "amount paid" column shows zero, it means neither Medicare nor your plan covered it, and you may owe the provider.

If you have Original Medicare (Part A and Part B), routine dental cleanings are not covered, so the amount paid should be zero. If you have Medicare Advantage, check your plan documents or call your plan to confirm whether dental is included and what the cleaning should have cost you.

If you see a charge you do not recognize or believe is wrong, write down the date of service, the provider's name, and the code, then contact your plan or Medicare to ask why it appears on your claim.

Original Medicare versus Medicare Advantage dental coverage

Original Medicare (Part A and Part B) does not cover dental care of any kind — not cleanings, not fillings, not extractions. If you see a dental code on an Original Medicare claim, it should show zero payment. If it shows a payment, contact Medicare to ask why.

Medicare Advantage plans vary widely in what they cover. Some include routine dental cleanings and exams; others cover only emergency dental work; some cover nothing dental at all. Your plan documents or member handbook will list what is covered. If you are unsure whether your plan covers cleanings, call the customer service number on your insurance card and ask whether D0108 (or any cleaning code) is covered and what you pay out of pocket.

What to do if you have questions about this code on your claim

Start by checking your explanation of benefits to see who paid. If you have Medicare Advantage, call your plan's customer service line and ask: "I see code D0108/fm on my claim from [date]. Did my plan cover this, and what should I have paid?" Have your member ID and the date of service ready.

If you have Original Medicare and see this code with a payment amount, contact Medicare directly at 1-800-MEDICARE (1-800-633-4227). Explain that you received a claim for a dental cleaning and ask whether it should have been covered. Medicare can tell you whether the provider billed correctly and whether you owe anything.

If the provider is asking you to pay and you believe Medicare or your plan should have covered it, ask the provider for an itemized bill showing what was done and what code was used. Keep this for your records and include it when you contact your insurance.

Frequently Asked Questions

Does Medicare cover dental cleanings for seniors?

Original Medicare does not cover any dental care, including cleanings. Some Medicare Advantage plans include dental benefits, but coverage varies by plan. Check your plan documents or call your plan to confirm what is covered.

What does the "fm" in D0108/fm mean?

The "fm" indicates that fluoride mouth rinse was used during the cleaning. This is a modifier that tells the insurance company exactly what was done. It does not change whether Medicare covers the service — Original Medicare covers neither D0108 nor D0108/fm.

I see this code on my claim but I do not remember getting a cleaning. What should I do?

Contact your provider's office first to confirm the date of service and what was done. If you did not receive the service, ask the provider to correct the claim. If the provider cannot explain it, contact your insurance plan or Medicare to report a potential billing error.

If I have Medicare Advantage with dental, what will I pay for a cleaning?

This depends on your specific plan. Some plans cover cleanings at no cost; others charge a copay (usually $0 to $50). Check your plan's summary of benefits or call customer service to find out what you owe for a cleaning.

Can I appeal if Medicare denied payment for a dental cleaning?

You can file an appeal, but Original Medicare will deny it because dental is not a covered service. If you have Medicare Advantage and your plan denied a cleaning you believe should be covered, follow your plan's appeal process, which is outlined in your member handbook.
