About L65

L65 is the ICD-10-CM diagnosis code for other nonscarring hair loss. It belongs to block L60-L75 (disorders of skin appendages) 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 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: L65.0 (effluvium), L65.1 (effluvium), L65.2 (mucinosa), L65.8 (loss) and L65.9 (unspecified).

Don't report L65 together with the conditions in its Excludes1 note: trichotillomania (F63.3).

Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).

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