S56.10 — Unspecified injury of flexor muscle, fascia and tendon of other and unspecified finger at forearm level
Is S56.10 billable?
No — S56.10 is a non-billable header code. S56.10 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 27 billable codes beneath S56.10.

How is S56.10 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to S56.10. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Injury › muscle › finger › flexor
Use additional code — inherited from Chapter 19
Report an additional code alongside S56.10 to fully describe the condition. S56.10 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 S56.10, but a patient may have both at the same time. When documentation supports it, S56.10 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S50-S59
The conditions below are not part of S56.10, but a patient may have both at the same time. When documentation supports it, S56.10 and the excluded code may both be reported.
