S86 — Injury of muscle, fascia and tendon at lower leg level
Not billable
Is S86 billable?
No — S86 is a non-billable header code. S86 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 S86.

Excludes2 — not included here
The conditions below are not part of S86, but a patient may have both at the same time. When documentation supports it, S86 and the excluded code may both be reported.
Code also
Two codes may be needed to describe the condition fully. Whether S86 is sequenced first depends on the reason for the encounter.
- any associated open wound (S81.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside S86 to fully describe the condition. S86 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 S86, but a patient may have both at the same time. When documentation supports it, S86 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S80-S89
The conditions below are not part of S86, but a patient may have both at the same time. When documentation supports it, S86 and the excluded code may both be reported.

How long has S86 existed?
S86 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.
