L03.8Cellulitis and acute lymphangitis of other sites

L03.8 is the ICD-10-CM diagnosis code for cellulitis and acute lymphangitis of other sites. It belongs to category L03 (cellulitis and acute lymphangitis), block L00-L08 (infections 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 2 subcodes must be used instead.

Within L03, choose L03.8 (of other sites) only when documentation doesn't support a more specific option: of finger and toe (L03.0), of other parts of limb (L03.1), of face and neck (L03.2), of trunk (L03.3) and unspecified (L03.9).

To report this condition, pick the subcode that matches the documentation: L03.81 (sites) and L03.89 (sites).

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