S86.1 — Injury of other muscle(s) and tendon(s) of posterior muscle group at lower leg level
Not billable
Is S86.1 billable?
No — S86.1 is a non-billable header code. S86.1 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 S86.1.

Use additional code — inherited from Chapter 19
Report an additional code alongside S86.1 to fully describe the condition. S86.1 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 S86.1, but a patient may have both at the same time. When documentation supports it, S86.1 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S80-S89
The conditions below are not part of S86.1, but a patient may have both at the same time. When documentation supports it, S86.1 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S86
The conditions below are not part of S86.1, but a patient may have both at the same time. When documentation supports it, S86.1 and the excluded code may both be reported.
Code also — inherited from S86
Two codes may be needed to describe the condition fully. Whether S86.1 is sequenced first depends on the reason for the encounter.
- any associated open wound (S81.-)

How long has S86.1 existed?
S86.1 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.
