Dislocation and sprain of joint and ligaments of hip (S73) ICD-10-CM

The S73 code range covers dislocation and sprain of joint and ligaments of hip with 180 ICD-10-CM diagnosis codes. 126 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.

Includes

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

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.

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.

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.

7th Character

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

About the S73 Code Range

The ICD-10 codes in the S73 section specifically classify various types of dislocation and sprain injuries of the hip joint and its ligaments. These codes are used for detailed documentation of hip injuries, ranging from general to very specific diagnoses such as subluxations, dislocations, and sprains of right, left, or unspecified hips.

This section covers multiple forms of hip joint injuries, including subluxations and dislocations like posterior dislocation (often referred to as "closed traumatic dislocation hip joint, posterior") and obturator dislocation (also known as "closed anterior dislocation of hip"). For sprains, it details common ligament injuries such as iliofemoral ligament sprain and ischiocapsular ligament sprain, with synonyms like "sprain of right hip" or "complete tear of iliofemoral ligament" helping medical coders link clinical terminology with precise ICD-10 codes. The section also distinguishes initial, subsequent, and sequela encounters for accurate billing and treatment tracking. Using the ICD-10 code for hip dislocation or sprain ensures clear communication and proper classification of hip joint injuries in healthcare records.

Questions About This Page

How many billable codes are in the S73 range?
