About B36

B36 is the ICD-10-CM diagnosis code for other superficial mycoses. It belongs to block B35-B49 (mycoses) and chapter 1 (certain infectious and parasitic diseases). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: B36.0 (versicolor), B36.1 (nigra), B36.2 (piedra), B36.3 (piedra), B36.8 (mycoses) and B36.9 (unspecified).

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