Cleanings and gum careBasicD4381

D4381. A slow-release antibiotic is tucked into a deep pocket after cleaning; billed per tooth.

A deep cleaning cleans below the gum line, scraping tartar off the roots and smoothing them so the gums can reattach. It is done with numbing, usually one side or one quarter of the mouth per visit. Related codes place antibiotic or rinse into a gum pocket.

The area is numbed first, then the hygienist or dentist works below the gum line, scraping tartar off the root surface and smoothing it so the gum can tighten back against the tooth. It is normally done one quarter of the mouth at a time over one or two visits. Separate codes cover placing an antibiotic into a deep pocket afterwards. Most plans file this as Basic. What they actually pay varies by plan.
