One question worth asking

What should I avoid doing while this heals?

Closing a sinus opening

Extractions and wisdom teethMajorD7260

D7260. Repairs an opening between the mouth and sinus that did not heal after an extraction.

Upper back teeth sit close to the sinus, and removing one can leave a small opening that has to be closed. Other codes cover removing a piece of dead bone or a fragment that went into the sinus.

The roots of upper back teeth sit close to the sinus, so removing one can leave a small opening that has to be closed with stitches or a small flap. Other codes here cover taking out a piece of bone that has died or retrieving a fragment that ended up in the sinus. These are follow-up surgeries rather than something planned in advance. Most plans file this as Major. What they actually pay varies by plan.
