S66.30 — Unspecified injury of extensor muscle, fascia and tendon of other and unspecified finger at wrist and hand level
Not billable
Is S66.30 billable?
No — S66.30 is a non-billable header code. S66.30 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 30 billable codes beneath S66.30.

Use additional code — inherited from Chapter 19
Report an additional code alongside S66.30 to fully describe the condition. S66.30 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 S66.30, but a patient may have both at the same time. When documentation supports it, S66.30 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S60-S69
The conditions below are not part of S66.30, but a patient may have both at the same time. When documentation supports it, S66.30 and the excluded code may both be reported.

The conditions below are not part of S66.30, but a patient may have both at the same time. When documentation supports it, S66.30 and the excluded code may both be reported.
- Injury of extensor muscle, fascia and tendon of thumb at wrist and hand level (S66.2-)
Code also — inherited from S66
Two codes may be needed to describe the condition fully. Whether S66.30 is sequenced first depends on the reason for the encounter.
- any associated open wound (S61.-)
