Loose body in knee, right knee

This code signifies the presence of a detached fragment of cartilage or bone within the right knee joint space. These loose bodies can cause mechanical symptoms such as locking, catching, pain, and effusion, interfering with normal knee function.

Use this code when diagnostic imaging (e.g., X-ray, MRI) or arthroscopy confirms the presence of a loose body in the right knee. Documentation should clearly specify the laterality and the identification of the loose body as the cause of the patient's knee symptoms.

• Ensure documentation specifies "right knee" to support laterality.
• Do not confuse with meniscal tears or osteochondral defects unless a detached fragment is explicitly noted.
• Consider sequencing this code as the primary diagnosis if it is the main reason for the encounter and treatment.
