L98.41Non-pressure chronic ulcer of buttock

L98.41 is the ICD-10-CM diagnosis code for Non-pressure chronic ulcer of buttock. It belongs to category L98 (other disorders of skin and subcutaneous tissue, not elsewhere classified), block L80-L99 (other disorders of the skin and subcutaneous tissue) and chapter 12 (diseases of the skin and subcutaneous tissue). It is a header code, so it can't be reported by itself; one of its 8 subcodes must be used instead.

Within L98.4 (Non-pressure chronic ulcer of skin, not elsewhere classified), L98.41 is specifically for Non-pressure chronic ulcer of buttock. Related codes cover back (L98.42), abdomen (L98.43), chest (L98.44), neck (L98.45), face (L98.46), groin (L98.47) and skin of other sites (L98.49).
