About B94

B94 is the ICD-10-CM diagnosis code for sequelae of other and unspecified infectious and parasitic diseases. It belongs to block B90-B94 (sequelae of infectious and parasitic diseases) and chapter 1 (certain infectious and parasitic diseases). 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: B94.0 (trachoma), B94.1 (encephalitis), B94.2 (hepatitis), B94.8 (diseases) and B94.9 (disease).

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