ICD-10 Code for Neutropenia
Also indexed as (chronic) (genetic) (idiopathic) (immune) (infantile) (malignant) (pernicious) (splenic)
The ICD-10-CM code for neutropenia is D70.9 — Neutropenia, unspecified. This is the code the Alphabetic Index gives for neutropenia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
D70.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which neutropenia code should you use?
The Alphabetic Index lists 8 codes under Neutropenia, neutropenic. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
