ICD-10 Code for Thrombocytopenia
The ICD-10-CM code for thrombocytopenia is D69.6 — Thrombocytopenia, unspecified. This is the code the Alphabetic Index gives for thrombocytopenia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
D69.6 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which thrombocytopenia code should you use?
The Alphabetic Index lists 13 codes under Thrombocytopenia, thrombocytopenic. 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.
