T79 — Certain early complications of trauma, not elsewhere classified
Not billable
Is T79 billable?
No — T79 is a non-billable header code. T79 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 54 billable codes beneath T79.

How long has T79 existed?
T79 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
