S83 is a non-billable ICD-10-CM category code for dislocation and sprain of joints and ligaments of knee, so it cannot be submitted on claims. Use a more specific code from this category instead, such as S83.001A, S83.001D, S83.001S, and S83.002A.

Coding GuidelinesGuidance

The appropriate 7th character is to be added to each code from block Dislocation and sprain of joints and ligaments of knee (S83). Use the following options for the applicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to S83: its own notes plus those printed at block S80-S89 and Chapter 19. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

  • avulsion of joint or ligament of knee
  • laceration of cartilage, joint or ligament of knee
  • sprain of cartilage, joint or ligament of knee
  • traumatic hemarthrosis of joint or ligament of knee
  • traumatic rupture of joint or ligament of knee
  • traumatic subluxation of joint or ligament of knee
  • traumatic tear of joint or ligament of knee

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

On S83 itself
  • derangement of patella (M22.0-M22.3)
  • injury of patellar ligament (tendon) (S76.1-)
  • internal derangement of knee (M23.-)
  • old dislocation of knee (M24.36)
  • pathological dislocation of knee (M24.36)
  • recurrent dislocation of knee (M22.0)
  • strain of muscle, fascia and tendon of lower leg (S86.-)
From Block S80-S89 Injuries to the knee and lower leg applies to 4,680 codes
  • burns and corrosions (T20-T32)
  • frostbite (T33-T34)
  • injuries of ankle and foot, except fracture of ankle and malleolus (S90-S99)
  • insect bite or sting, venomous (T63.4)
From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes

Use Additional Code

Add a second code, after this one, to fully describe the condition.

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • code to identify any retained foreign body, if applicable (Z18.-)

Code Also

A second code may be needed to fully describe the condition; the note gives no sequencing direction.

  • any associated open wound

Notes

General instructions on how these codes are used.

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
  • The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.

7th Character

Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.

  • The appropriate 7th character is to be added to each code from category S83
Values for category S83 Encounter: Initial, Subsequent, Sequela
  • Ainitial encounter
  • Dsubsequent encounter
  • Ssequela

Referenced in Other NotesGuidance

Instructional notes printed at other codes that name S83, its category, or a range that includes it.

Excludes2 1

These codes carry an Excludes2 note naming S83: its condition is not part of those codes, and both may be reported when the patient has both.

  • S86 Injury of muscle, fascia and tendon at lower leg level
    sprain of joints and ligaments of knee (S83.-)

Patient EducationClinical

Dislocations

Dislocations are joint injuries that force the ends of your bones out of position. The cause is often a fall or a blow, sometimes from playing a contact sport. You can dislocate your ankles, knees, shoulders, hips, elbows and jaw. You can also dislocate your finger and toe joints.

Questions About S83Overview

What is the ICD-10 code for dislocation and sprain of joints and ligaments of knee?

S83 is the ICD-10-CM category for dislocation and sprain of joints and ligaments of knee, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is S83 (Dislocation and sprain of joints and ligaments of knee) a billable code?

No. This is a category header that groups the codes for dislocation and sprain of joints and ligaments of knee, and headers cannot be submitted on claims. Claims for dislocation and sprain of joints and ligaments of knee need a more specific code from this category, such as S83.001A, S83.001D, and S83.001S.
