D70 — Neutropenia
Is D70 billable?
No — D70 is a non-billable header code. D70 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 7 billable codes beneath D70.

Use additional code
Report an additional code alongside D70 to fully describe the condition. D70 is sequenced first.
