About coding granulomatosis
The ICD-10-CM code for granulomatosis is L92.9 (Granulomatous disorder of the skin and subcutaneous tissue, unspecified). The official index lists 9 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on L92.9.
Within L92, choose L92.9 (Granulomatous disorder of the skin and subcutaneous tissue, unspecified) only when documentation doesn't support a more specific option: granuloma annulare (L92.0), Necrobiosis lipoidica, not elsewhere classified (L92.1), granuloma faciale [eosinophilic granuloma of skin] (L92.2), foreign body granuloma of the skin and subcutaneous tissue (L92.3) and other granulomatous disorders of the skin and subcutaneous tissue (L92.8).
The conditions in its Excludes2 note aren't part of L92.9, but may be coded alongside it if the patient has both: umbilical granuloma (P83.81).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
