About coding polycythemia

The ICD-10-CM code for polycythemia is D75.1 (Secondary polycythemia). The official index lists 22 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on D75.1.

Within D75 (other and unspecified diseases of blood and blood-forming organs), D75.1 is specifically for secondary polycythemia. Related codes cover familial erythrocytosis (D75.0), other specified diseases of blood and blood-forming organs (D75.8), disease of blood and blood-forming organs, unspecified (D75.9) and glucose-6-phosphate dehydrogenase (G6PD) deficiency without anemia (D75.A).

Don't report D75.1 together with the conditions in its Excludes1 note: polycythemia neonatorum (P61.1) and polycythemia vera (D45).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
