Loose body, other site

This code signifies the presence of a detached fragment of cartilage, bone, or other tissue within a joint capsule or bursa, excluding specific joints like the shoulder, elbow, wrist, hand, hip, knee, ankle, or foot. These loose bodies can cause pain, locking, clicking, or restricted range of motion.

Apply this code when documentation specifies a loose body in a joint not otherwise classified, such as the temporomandibular joint, sacroiliac joint, or a vertebral facet joint. Supporting documentation should clearly identify the presence of a loose body and the affected "other" joint.

• Ensure the documentation explicitly states "other site" or specifies a joint not covered by more specific M24.0x codes.
• Do not use this code if a more specific M24.0x code exists for the documented joint (e.g., M24.05 for loose body in hip).
• Code any associated arthritis or other joint pathology separately, if documented.
