About D50
D50 is the ICD-10-CM diagnosis code for iron deficiency anemia. It belongs to block D50-D53 (nutritional anemias) 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 4 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: D50.0 (secondary to blood loss (chronic)), D50.1 (dysphagia), D50.8 (anemias) and D50.9 (unspecified).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
