About L82

L82 is the ICD-10-CM diagnosis code for seborrheic keratosis. It belongs to 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 2 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: L82.0 (keratosis) and L82.1 (keratosis).

The conditions in its Excludes2 note aren't part of L82, but may be coded alongside it if the patient has both: seborrheic dermatitis (L21.-).

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