S56 — Injury of muscle, fascia and tendon at forearm level
Is S56 billable?
No — S56 is a non-billable header code. S56 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 S56.

Two codes may be needed to describe the condition fully. Whether S56 is sequenced first depends on the reason for the encounter.
- any associated open wound (S51.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside S56 to fully describe the condition. S56 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 S56, but a patient may have both at the same time. When documentation supports it, S56 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S50-S59
The conditions below are not part of S56, but a patient may have both at the same time. When documentation supports it, S56 and the excluded code may both be reported.

How long has S56 existed?
S56 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.
