Loose body in right hip

This code signifies the presence of a detached fragment of cartilage, bone, or other tissue within the right hip joint capsule. These loose bodies, also known as joint mice, can cause mechanical symptoms such as locking, catching, pain, and effusion. Their presence often indicates underlying joint pathology like osteoarthritis or trauma.

Apply this code when documentation explicitly states a "loose body" or "joint mouse" is identified in the right hip. This diagnosis is typically confirmed through imaging studies such as X-rays, MRI, or CT scans, or observed during arthroscopy. The patient's symptoms should align with mechanical joint dysfunction.

• Ensure laterality is clearly documented (right hip).
• Do not confuse with foreign body in joint, which implies external introduction.
• Code any underlying conditions contributing to the loose body (e.g., osteoarthritis, osteochondritis dissecans) as additional diagnoses.
