About coding Constant Spring hemoglobin
The ICD-10-CM code for Constant Spring hemoglobin is D58.2 (Other hemoglobinopathies).
Within D58, choose D58.2 (Other hemoglobinopathies) only when documentation doesn't support a more specific option: hereditary spherocytosis (D58.0), hereditary elliptocytosis (D58.1), other specified hereditary hemolytic anemias (D58.8) and hereditary hemolytic anemia, unspecified (D58.9).
Don't report D58.2 together with the conditions in its Excludes1 note: familial polycythemia (D75.0), Hb-M disease (D74.0), hemoglobin E-beta thalassemia (D56.5), hereditary persistence of fetal hemoglobin [HPFH] (D56.4) and 3 more.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for D58.2)
