B42.8Other forms of sporotrichosis

B42.8 is the ICD-10-CM diagnosis code for other forms of sporotrichosis. It belongs to category B42 (sporotrichosis), 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 3 subcodes must be used instead.

Within B42, choose B42.8 (Other forms of sporotrichosis) only when documentation doesn't support a more specific option: pulmonary sporotrichosis (B42.0), Lymphocutaneous sporotrichosis (B42.1), disseminated sporotrichosis (B42.7) and unspecified (B42.9).

To report this condition, pick the subcode that matches the documentation: B42.81 (sporotrichosis), B42.82 (arthritis) and B42.89 (sporotrichosis).

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