2025 ICD-10-CM code S73.04

Central dislocation of the hip.

Use secondary codes from Chapter 20 (External causes of morbidity) to specify the cause of the injury. If a foreign body is retained, use Z18.-.

Medical necessity for treatment of central hip dislocation is established by the presence of the dislocation itself, which impairs function and may cause significant pain and long-term complications if left untreated.

Physicians diagnose central hip dislocations based on physical examination, imaging studies (X-rays, MRI, CT scans), and evaluation of nerve and blood supply function. Treatment involves joint reduction (putting the bone back into the socket), pain management, immobilization, and sometimes surgery for associated injuries or to prevent recurrence.

In simple words: A central hip dislocation is a serious injury where the top of your thigh bone is pushed out of its socket in your hip, usually downwards and inwards, often breaking part of the socket. This happens because of a strong force like a car crash or a bad fall.

Central dislocation of hip, also known as superior or medial hip dislocation. This involves the complete displacement of the femoral head through the floor of the acetabulum, often resulting in an acetabular fracture. It typically occurs due to high-impact trauma like a motor vehicle accident or a fall.

Example 1: A 25-year-old male is involved in a high-speed motor vehicle accident and presents with severe hip pain and inability to move his leg. Imaging reveals a central dislocation of the hip with an associated acetabular fracture., A 70-year-old female falls from a ladder and experiences acute hip pain. Examination and X-rays confirm a central hip dislocation., A 10-year-old child falls from a tree and sustains multiple injuries including central dislocation of his hip. Surgical repair is required.

Documentation should include details of the traumatic event, physical exam findings (e.g., deformity, limited range of motion, neurovascular status), imaging results, treatment provided (e.g., reduction, surgery), and any associated injuries.

** Do not use this code for birth trauma (P10-P15) or obstetric trauma (O70-O71).Long-term complications of central hip dislocation can include avascular necrosis, post-traumatic arthritis, and recurrent dislocation.
