L89.9Pressure ulcer of unspecified site

L89.9 is the ICD-10-CM diagnosis code for pressure ulcer of unspecified site. 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, choose L89.9 (of unspecified site) only when documentation doesn't support a more specific option: of elbow (L89.0), of back (L89.1), of hip (L89.2), of buttock (L89.3), of contiguous site of back, buttock and hip (L89.4), of ankle (L89.5), of heel (L89.6) and of other site (L89.8).

To report this condition, pick the subcode that matches the documentation: L89.90 (unspecified stage), L89.91 (stage 1), L89.92 (stage 2), L89.93 (stage 3), L89.94 (stage 4), L89.95 (unstageable) and L89.96 (site).

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.
