ICD-10 Code for Leukemia
The ICD-10-CM code for leukemia is C95.9 — Leukemia, unspecified. This is the code the Alphabetic Index gives for leukemia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
Not billable
C95.9 cannot be submitted on a claim. It is a header code, so a more specific code from the list below is required.
Which leukemia code should you use?
The Alphabetic Index lists 32 codes under Leukemia, leukemic. 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.
