S83.11 — Anterior subluxation and dislocation of proximal end of tibia
Is S83.11 billable?
No — S83.11 is a non-billable header code. S83.11 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 18 billable codes beneath S83.11.

How is S83.11 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to S83.11. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Dislocation › knee › proximal tibia › anteriorly (articular)
- Subluxation › knee › proximal tibia › anteriorly
Inclusion terms
Alternative wording in documentation that is classified to S83.11.
- Posterior subluxation and dislocation of distal end of femur
Use additional code — inherited from Chapter 19
Report an additional code alongside S83.11 to fully describe the condition. S83.11 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 S83.11, but a patient may have both at the same time. When documentation supports it, S83.11 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S80-S89
The conditions below are not part of S83.11, but a patient may have both at the same time. When documentation supports it, S83.11 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S83
The conditions below are not part of S83.11, but a patient may have both at the same time. When documentation supports it, S83.11 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S83.1
The conditions below are not part of S83.11, but a patient may have both at the same time. When documentation supports it, S83.11 and the excluded code may both be reported.
Code also — inherited from S83
Two codes may be needed to describe the condition fully. Whether S83.11 is sequenced first depends on the reason for the encounter.

What codes fall under S83.11? (6)
- S83.111Anterior subluxation of proximal end of tibia, right kneenot billable
- S83.112Anterior subluxation of proximal end of tibia, left kneenot billable
- S83.113Anterior subluxation of proximal end of tibia, unspecified kneenot billable

How long has S83.11 existed?
S83.11 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.
