ICD-10 Code for Compartment Syndrome
Also indexed as (deep) (posterior) (traumatic)
The ICD-10-CM code for compartment Syndrome is T79.A0 — Compartment syndrome, unspecified. This is the code the Alphabetic Index gives for compartment Syndrome with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
T79.A0 cannot be submitted on a claim. It is a header code, so a more specific code from the list below is required.
Which compartment Syndrome code should you use?
The Alphabetic Index lists 9 codes under Compartment syndrome. 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.
