Medicare covers some oral surgery, but it does not cover most routine dental care. Coverage depends on why the procedure is needed and whether it is directly related to a Medicare-covered medical service.
When Medicare may cover oral surgery
Medicare may cover an oral examination and necessary dental treatment before certain covered medical procedures. Examples include a heart valve repair or replacement, an organ transplant, or certain cancer treatment. It may cover a procedure to remove an oral infection before covered chemotherapy, treatment of complications caused by head and neck cancer care, and certain oral or dental services related to covered dialysis treatment.
Part A may cover an oral procedure during an inpatient hospital stay when hospitalization is necessary because of the person’s underlying medical condition or the severity of the procedure. Part B may cover an eligible outpatient service that is inextricably linked to a covered medical treatment.
Medicare generally does not cover routine tooth extraction, treatment of dental disease, implants, dentures, or other replacement teeth. If a covered medical service requires an extraction, later replacement of the tooth is generally not covered by Original Medicare.
Costs and Medicare Advantage
A person pays all costs for noncovered dental surgery. For Part B-covered services, the Part B deductible and 20 percent coinsurance generally apply when the provider accepts assignment. Part A hospital costs apply to a covered inpatient stay.
Medicare Advantage plans must cover oral surgery that Original Medicare covers and may offer extra dental benefits. An extra dental benefit can have a separate network, annual maximum, frequency limit, or prior authorization rule. Coverage should be confirmed for the exact procedure code and provider.
What to do next
- Ask the surgeon to state the medical reason for the procedure and its connection to covered treatment.
- Request the procedure codes and a written estimate.
- Confirm Medicare enrollment or plan network status for both the surgeon and facility.
- Ask how anesthesia, pathology, and facility fees will be billed.
- Review Medicare’s official dental services coverage.

Coverage and costs can change each calendar year. Check current Medicare rules and current plan documents before receiving care. A provider’s estimate is not a Medicare coverage decision. Final payment depends on the claim and the applicable coverage requirements.
