Not billable
Is S66.9 billable?
No — S66.9 is a non-billable header code. S66.9 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 S66.9.

Use additional code — inherited from Chapter 19
Report an additional code alongside S66.9 to fully describe the condition. S66.9 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 S66.9, but a patient may have both at the same time. When documentation supports it, S66.9 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S60-S69
The conditions below are not part of S66.9, but a patient may have both at the same time. When documentation supports it, S66.9 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S66
The conditions below are not part of S66.9, but a patient may have both at the same time. When documentation supports it, S66.9 and the excluded code may both be reported.
- sprain of joints and ligaments of wrist and hand (S63.-)
Code also — inherited from S66
Two codes may be needed to describe the condition fully. Whether S66.9 is sequenced first depends on the reason for the encounter.
- any associated open wound (S61.-)
