About coding Intermedia thalassemia
The ICD-10-CM code for Intermedia thalassemia is D56.1 (Beta thalassemia).
Within D56 (thalassemia), D56.1 is specifically for beta thalassemia. Related codes cover alpha thalassemia (D56.0), Delta-beta thalassemia (D56.2), minor (D56.3), hereditary persistence of fetal hemoglobin [HPFH] (D56.4), hemoglobin E-beta thalassemia (D56.5), other thalassemias (D56.8) and unspecified (D56.9).
Don't report D56.1 together with the conditions in its Excludes1 note: beta thalassemia minor (D56.3), beta thalassemia trait (D56.3), delta-beta thalassemia (D56.2), hemoglobin E-beta thalassemia (D56.5) and 1 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 D56.1)
