T79.A — Traumatic compartment syndrome
Is T79.A billable?
No — T79.A is a non-billable header code. T79.A groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 27 billable codes beneath T79.A.

Excludes1 — never code together
The conditions below can never be reported together with T79.A on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here
The conditions below are not part of T79.A, but a patient may have both at the same time. When documentation supports it, T79.A and the excluded code may both be reported.
- traumatic ischemic infarction of muscle (T79.6)
Use additional code — inherited from Chapter 19
Report an additional code alongside T79.A to fully describe the condition. T79.A is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of T79.A, but a patient may have both at the same time. When documentation supports it, T79.A and the excluded code may both be reported.
