Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the M27 range.
Cherubism
A fibro-osseous hereditary disease of the jaws. The swollen jaws and raised eyes give a cherubic appearance; multiple radiolucencies are evident upon radiographic examination.
Granuloma, Giant Cell
A non-neoplastic inflammatory lesion, usually of the jaw or gingiva, containing large, multinucleated cells. It includes reparative giant cell granuloma. Peripheral giant cell granuloma refers to the gingiva (giant cell epulis); central refers to the jaw.
Osteoradionecrosis
Necrosis of bone following radiation injury.
About the M27 Code Range
These jaw diseases include developmental and inflammatory conditions, cysts, problems after root canal treatment, and dental implant failure.
M27 separates jaw diseases by condition or problem. M27.4 distinguishes other jaw cysts from unspecified ones. M27.5 groups problems around a tooth root after root canal treatment, distinguishing a perforation, overfilling, underfilling, and other problems. M27.6 distinguishes failure of implant integration from biological or mechanical failure after integration, as well as other implant failure. Other subdivisions identify developmental and inflammatory conditions, additional named conditions, and other specified or unspecified jaw diseases.
