D75.1

D75.1 — Secondary polycythemia

Billable / specific codeICD-10-CM

D75.1 is a billable, specific ICD-10-CM code for secondary polycythemia. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

polycythemia vera (D45)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Acquired polycythemia
Emotional polycythemia
Erythrocytosis NOS
Hypoxemic polycythemia

Polycythemia due to erythropoietin
Polycythemia due to fall in plasma volume
Polycythemia due to high altitude
Polycythemia due to stress

Other codes that can never be billed with D75.1

These codes carry an Excludes1 note pointing at D75.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D75.1 alone.

R71Abnormality of red blood cells
D45Polycythemia vera
D58.2Other hemoglobinopathies

Risk adjustment

D75.1 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

D75.1 is named in 12 Medicare coverage policies — 12 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
