About D80
D80 is the ICD-10-CM diagnosis code for immunodeficiency with predominantly antibody defects. It belongs to block D80-D89 (certain disorders involving the immune mechanism) and chapter 3 (diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: D80.0 (hypogammaglobulinemia), D80.1 (hypogammaglobulinemia), D80.2 ([IgA]), D80.3 (subclasses), D80.4 ([IgM]), D80.5 ([IgM]), D80.6 (hyperimmunoglobulinemia), D80.7 (infancy) and 2 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
