About coding palate hard hypertrophy
The ICD-10-CM code for palate hard hypertrophy is M27.8 (Other specified diseases of jaws). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on M27.8.
Within M27, choose M27.8 (Other specified diseases of jaws) only when documentation doesn't support a more specific option: developmental disorders of jaws (M27.0), giant cell granuloma, central (M27.1), inflammatory conditions of jaws (M27.2), alveolitis of jaws (M27.3), other and unspecified cysts of jaw (M27.4), periradicular pathology associated with previous endodontic treatment (M27.5), endosseous dental implant failure (M27.6) and disease of jaws, unspecified (M27.9).
Don't report M27.8 together with the conditions in its Excludes1 note: jaw pain (R68.84).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
