S56.3 — Injury of extensor or abductor muscles, fascia and tendons of thumb at forearm level
Not billable
Is S56.3 billable?
No — S56.3 is a non-billable header code. S56.3 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 36 billable codes beneath S56.3.

Use additional code — inherited from Chapter 19
Report an additional code alongside S56.3 to fully describe the condition. S56.3 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 S56.3, but a patient may have both at the same time. When documentation supports it, S56.3 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S50-S59
The conditions below are not part of S56.3, but a patient may have both at the same time. When documentation supports it, S56.3 and the excluded code may both be reported.
