About B05.8

B05.8 is the ICD-10-CM diagnosis code for measles with other complications. It belongs to category B05 (measles), block B00-B09 (viral infections characterized by skin and mucous membrane lesions) 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 B05, choose B05.8 (with other complications) only when documentation doesn't support a more specific option: complicated by encephalitis (B05.0), complicated by meningitis (B05.1), complicated by pneumonia (B05.2), complicated by otitis media (B05.3), with intestinal complications (B05.4) and without complication (B05.9).

To report this condition, pick the subcode that matches the documentation: B05.81 (keratoconjunctivitis) and B05.89 (complications).

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