Loose body in left shoulder

This code signifies the presence of a detached fragment of cartilage, bone, or other tissue within the synovial joint space of the left shoulder. These "loose bodies" can cause mechanical symptoms such as locking, catching, pain, and reduced range of motion. They are often a result of trauma, degenerative changes, or osteochondritis dissecans.

Apply this code when documentation clearly indicates a loose body is identified within the left shoulder joint. This diagnosis is typically supported by imaging studies such as X-rays, MRI, or CT scans, and confirmed during arthroscopy or open surgery. Use when the patient presents with symptoms directly attributable to the loose body.

• Ensure laterality is accurately documented and coded; this code specifies the left shoulder.
• Distinguish from foreign body, which implies external origin, whereas a loose body is endogenous.
• Code any associated underlying conditions (e.g., osteoarthritis, trauma) separately as secondary diagnoses.
