Is D70 a billable ICD-10-CM code?

No. D70 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does D70 sit in the tabular list?

Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (D50-D89), in the block Other disorders of blood and blood-forming organs (D70-D77).

What cannot be coded together with D70?

D70 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

D70 — Neutropenia

Non-billable headerICD-10-CM

D70 is a non-billable header ICD-10-CM code for neutropenia. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

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

neutropenic splenomegaly (D73.81)
transient neonatal neutropenia (P61.5)

Use additional code

Add a secondary code to capture the detail described below.

code for any associated:
fever (R50.81)

Code also

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

, if applicable, mucositis (J34.81, K12.3-, K92.81, N76.81)

Includes

Conditions this code covers.

agranulocytosis
decreased absolute neurophile count (ANC)

Other codes that can never be billed with D70

These codes carry an Excludes1 note pointing at D70. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D70 alone.

P61.5Transient neonatal neutropenia

Risk adjustment

D70 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.

Code to one of these instead D70

7 child codes. Green means billable.
