S83.1 — Subluxation and dislocation of knee
Not billable
Is S83.1 billable?
No — S83.1 is a non-billable header code. S83.1 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 60 billable codes beneath S83.1.

Excludes2 — not included here
The conditions below are not part of S83.1, but a patient may have both at the same time. When documentation supports it, S83.1 and the excluded code may both be reported.
Use additional code — inherited from Chapter 19
Report an additional code alongside S83.1 to fully describe the condition. S83.1 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)

How long has S83.1 existed?
S83.1 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.
