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.
