Loose body in right ankle

This code signifies the presence of a detached fragment of bone or cartilage within the right ankle joint space. These loose bodies, also known as joint mice, can cause pain, locking, clicking, and restricted range of motion.

Apply this code when documentation clearly indicates a loose body identified in the right ankle. This often follows imaging studies such as X-rays, MRI, or CT scans, or is discovered during arthroscopy. The patient typically presents with symptoms consistent with intra-articular loose bodies.

• Ensure laterality is explicitly documented as "right ankle" to support this specific code.
• Distinguish from other ankle derangements, such as internal derangement NOS or specific ligamentous injuries.
• Code any associated conditions, such as osteoarthritis or osteochondritis dissecans, as secondary diagnoses.
