2025 ICD-10-CM code T84.021

Dislocation of internal left hip prosthesis. This code describes a mechanical complication involving the dislocation of an internal left hip prosthesis.

Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Use additional code to identify any retained foreign body, if applicable (Z18.-).

Medical necessity is established by the presence of a dislocated left hip prosthesis causing pain, immobility, or instability. Treatment is necessary to restore function and alleviate symptoms.

The physician is responsible for diagnosing the dislocation, managing the patient's pain, performing a closed reduction if possible, and determining if further surgery or other interventions are necessary.

In simple words: Your left hip replacement has become dislocated. This means the ball of the artificial hip joint has come out of its socket.

Dislocation of internal left hip prosthesis. This condition occurs when the ball of the prosthetic hip joint becomes displaced from the socket.

Example 1: A patient presents to the emergency room after a fall, complaining of severe left hip pain. Imaging reveals a dislocation of their previously implanted left hip prosthesis., During a routine follow-up appointment after a left hip replacement, a patient reports a clicking sensation in their hip and some discomfort. Upon examination, the physician determines that the prosthesis is partially dislocated., A patient with a history of left hip replacement experiences sudden pain and immobility in their left hip while performing a bending exercise. They present to the clinic, and imaging confirms a complete dislocation of the prosthesis.

Documentation should include details of the event leading to the dislocation, the patient's symptoms, physical examination findings, imaging results confirming the diagnosis, and any procedures performed, such as closed reduction or revision surgery.
