B44.8Other forms of aspergillosis

B44.8 is the ICD-10-CM diagnosis code for other forms of aspergillosis. It belongs to category B44 (aspergillosis), 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 2 subcodes must be used instead.

Within B44, choose B44.8 (Other forms of aspergillosis) only when documentation doesn't support a more specific option: invasive pulmonary aspergillosis (B44.0), other pulmonary aspergillosis (B44.1), tonsillar aspergillosis (B44.2), disseminated aspergillosis (B44.7) and unspecified (B44.9).

To report this condition, pick the subcode that matches the documentation: B44.81 (aspergillosis) and B44.89 (aspergillosis).

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