Dislocation and sprain of joints and ligaments of thorax (S23)

Browse all the diagnosis codes used for dislocation and sprain of joints and ligaments of thorax (s23). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Instructional Notations

Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

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

Code Also

A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.

  • any associated open wound

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

  • dislocation, sprain of sternoclavicular joint S43.2 S43.6
  • strain of muscle or tendon of thorax S29.01

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

  • The appropriate 7th character is to be added to each code from category S23

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela
  • Injury, poisoning and certain other consequences of external causes (S00–T88)
