Child prophylaxis, commonly called a routine child dental cleaning.
What D1120 usually means
Dentists use D1120 when billing for child prophylaxis, commonly called a routine child dental cleaning.
Why it may appear on your bill
A dental office uses CDT codes to describe the service performed, submit the claim to insurance, and calculate your patient responsibility. If D1120 appears on your statement, compare the dentist's billed charge against the insurance allowed amount and any deductible, coinsurance, or denial reason on your EOB.
What to check before you pay
- • Confirm the code on the bill matches the code on the EOB.
- • Check whether insurance allowed the charge, denied it, or downcoded it.
- • Compare the provider's billed charge to the negotiated or allowed amount.
- • Ask the office for the clinical reason if the code does not match what you remember receiving.
- • Preventive services are often covered better than treatment codes, but age limits and frequency limits still matter.
