ICD-10 Code for Cytopenia
The ICD-10-CM code for cytopenia is D75.9 — Disease of blood and blood-forming organs, unspecified. This is the code the Alphabetic Index gives for cytopenia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
D75.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which cytopenia code should you use?
The Alphabetic Index lists 3 codes under Cytopenia. 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.
Index terms and codes are reproduced from the official ICD-10-CM FY2027 release. The Alphabetic Index is a finding aid — a code must always be verified in the Tabular List before it is reported. Data sources
