ICD-10-CM › S00-T88 › T79 › T79.A Traumatic compartment syndrome › T79.A3

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 3 more specific codes instead:

• T79.A3XA Traumatic compartment syndrome of abdomen, initial encounter
• T79.A3XD Traumatic compartment syndrome of abdomen, subsequent encounter
• T79.A3XS Traumatic compartment syndrome of abdomen, sequela

This code requires a seventh character. See the rule below.
