About L01.0

L01.0 is the ICD-10-CM diagnosis code for impetigo. It belongs to category L01 (impetigo), 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 5 subcodes must be used instead.

Within L01 (impetigo), L01.0 is specifically for impetigo. Related codes cover Impetiginization of other dermatoses (L01.1).

To report this condition, pick the subcode that matches the documentation: L01.00 (unspecified), L01.01 (impetigo), L01.02 (impetigo), L01.03 (impetigo) and L01.09 (impetigo).

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