T84.21 — Breakdown (mechanical) of internal fixation device of other bones
Is T84.21 billable?
No — T84.21 is a non-billable header code. T84.21 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 12 billable codes beneath T84.21.

How long has T84.21 existed?
T84.21 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.
