T79.A: Traumatic compartment syndrome

Non-billable headerICD-10-CM

T79.A is a non-billable header ICD-10-CM code for traumatic compartment syndrome. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

This code requires a 7th character

The appropriate 7th character is to be added to each code from category T79

A: initial encounter
D: subsequent encounter
S: sequela

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

fibromyalgia (M79.7)
nontraumatic compartment syndrome (M79.A-)

Excludes2: not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

traumatic ischemic infarction of muscle (T79.6)

Excludes2 inherited from the categories above T79.A

Not part of this code, but both may be coded when both are present.
