L81Other disorders of pigmentation

L81 is the ICD-10-CM diagnosis code for other disorders of pigmentation. 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 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: L81.0 (hyperpigmentation), L81.1 (Chloasma), L81.2 (Freckles), L81.3 (spots), L81.4 (hyperpigmentation), L81.5 (classified), L81.6 (formation), L81.7 (dermatosis) and 2 more.

Don't report L81 together with the conditions in its Excludes1 note: birthmark NOS (Q82.5) and Peutz-Jeghers syndrome (Q85.89).

The conditions in its Excludes2 note aren't part of L81, but may be coded alongside it if the patient has both: nevus - see Alphabetical Index.

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