L89.30Pressure ulcer of unspecified buttock

L89.30 is the ICD-10-CM diagnosis code for pressure ulcer of unspecified buttock. It belongs to category L89 (pressure ulcer), 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 7 subcodes must be used instead.

Within L89.3, choose L89.30 (unspecified buttock) only when documentation doesn't support a more specific option: right buttock (L89.31) and left buttock (L89.32).

To report this condition, pick the subcode that matches the documentation: L89.300 (unstageable), L89.301 (stage 1), L89.302 (stage 2), L89.303 (stage 3), L89.304 (stage 4), L89.306 (buttock) and L89.309 (unspecified stage).

Code first: any associated gangrene (I96).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
