2025 ICD-10-CM code S73.045S

Sequela of central dislocation of the left hip.

Code S73.045S should only be used when the encounter is specifically for the management of sequelae. If the encounter focuses on the acute dislocation, the appropriate initial encounter code from the S73.04 series should be used.

Modifiers may be applicable depending on the circumstances of the encounter and services provided.Consult the appropriate payer guidelines for modifier usage.

Medical necessity is established by the presence of persistent symptoms (pain, limited range of motion, instability) and confirmation of the sequela via physical examination and appropriate imaging studies.Documentation should support the continued need for treatment based on the ongoing impairment.

Diagnosis involves patient history, physical exam (assessing nerves and blood supply), imaging (X-rays, MRI), and lab tests (hemoglobin, hematocrit, coagulation factors). Treatment may range from manual reduction and immobilization to surgery (open reduction and internal fixation, hip arthroplasty), pain management (narcotics, NSAIDs), and physical therapy.

IMPORTANT Consider additional codes from Chapter 20 (External causes of morbidity) to specify the cause of the injury.If a retained foreign body is present, use code(s) from category Z18.-.

In simple words: This code is for the long-term problems that happen after a severe injury where the hip joint pops out of place (a central dislocation of the left hip).It covers things like ongoing pain or stiffness after the hip has been put back in place.

This code signifies a sequela (a condition that is a consequence of a previous disease or injury) of a central dislocation of the left hip.A central dislocation involves complete medial displacement of the left femoral head through the acetabulum's floor, often resulting in an acetabular fracture.This typically occurs due to a significant impact, such as a fall, motor vehicle accident, or direct blow. The code applies to an encounter focused on the lasting effects of this injury.

Example 1: A patient presents with a sequela of a central hip dislocation sustained in a motor vehicle accident 6 months prior. They report persistent pain and limited range of motion. Imaging confirms avascular necrosis of the femoral head., A patient with a history of left hip dislocation (reduced in the ED) presents to physical therapy for ongoing pain and stiffness after an initial surgical repair. This session focuses on exercises to regain function and mobility., A patient experiences chronic pain and limited mobility in the left hip, a sequela from a central hip dislocation that occurred during a sporting event several years ago.MRI reveals mild osteonecrosis.

Detailed patient history including mechanism of injury, date of injury, prior treatment, and imaging results (X-rays, MRI).Physical exam findings should include neurovascular assessment and range of motion testing.Lab results related to blood loss and clotting should be documented.Surgical notes, physical therapy reports and any other relevant progress notes are required if applicable.

** Excludes birth trauma (P10-P15) and obstetric trauma (O70-O71).Also excludes dislocations and subluxations of hip prosthesis (T84.020, T84.021).
