    ICD-10-CM Code For Dislocation And Sprain Of Joint And Ligaments Of Hip: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group S73 includes dislocations and sprains of the hip joint and associated ligaments, covering acute traumatic displacements and ligamentous injuries of the hip region. These ICD-10-CM diagnosis codes are used to document specific injury types, laterality, and encounter type, capturing clinical complexity and severity relevant to hip joint trauma. Accurate coding within the ICD-10-CM S73 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM S73: Dislocation And Sprain Of Joint And Ligaments Of Hip Overview

    The ICD-10-CM S73 group captures diagnoses for dislocations and sprains affecting the hip joint and its supporting ligaments. These codes represent traumatic or injury-related instability and soft tissue damage of the hip region within the musculoskeletal system. Accurate coding matters because it supports correct clinical documentation and informs reimbursement and claim adjudication for injury care.

    When to Use

    Use a code from this group when a patient presents with a documented dislocation of the hip joint or a sprain/ligamentous injury of the hip confirmed by clinical evaluation or imaging. Select codes that reflect laterality, initial versus subsequent encounter, and any associated complications as specified in the clinical documentation.

    Typical Clinical Scenarios

    • An adult presents to the emergency department after a high-energy motor vehicle collision with severe lateral hip pain, inability to move the leg, and obvious deformity of the hip on exam. Radiographs show a displaced posterior dislocation of the right hip without open wound; the visit is for initial emergency care and closed reduction is performed. Typical codes: S73.011A, S73.012A
    • An elderly patient with osteoporosis develops progressive hip instability and recurrent subluxation after a recent low-energy fall; they are seen in clinic weeks later for persistent groin pain and limited weight bearing. Imaging demonstrates an old, malunited dislocation or chronic dislocation sequelae requiring orthopedic follow-up and possible planned surgical stabilization; the encounter documents subsequent care for the ongoing condition. Typical codes: S73.001D, S73.002D
    • A patient previously treated for a surgically repaired hip dislocation returns months later with pain and stiffness from post-reduction complications and limited range of motion; the visit is for routine postoperative evaluation and management of the residual ligamentous injury and joint dysfunction. Typical codes: S73.001S, S73.011S
