S23 — Dislocation and sprain of joints and ligaments of thorax
Not billable
Is S23 billable?
No — S23 is a non-billable header code. S23 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 60 billable codes beneath S23.

How long has S23 existed?
S23 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.
