Questions about D7998

What does dental code D7998 mean?

The procedure behind the number is intraoral fixation device, not for a fracture, filed under oral and maxillofacial surgery.

How much does D7998 cost?

Expect $400–$1,200. Ask for the number in writing, because the code carries no fee of its own and every practice sets its own.

Will my plan pay for D7998?

Yes on most policies, treated as medical / oral surgery work at variable. A waiting period on a new policy is the commonest reason it is not.

What is the difference between D7998 and D7997?

D7997 is appliance removal, not by the dentist who placed it: it removes an appliance that a different dentist placed, and is billed by the practice picking the case up. Because they describe different work, D7998 and D7997 can legitimately appear on the same treatment plan — they are not alternatives to choose between.

Also known as: jaw fracture, facial trauma, open reduction, closed reduction, maxillofacial injury.
