Loose body in left toe joint(s)

This code signifies the presence of a detached fragment of cartilage or bone within the synovial joint of the left toe. 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 within any joint of the left toe. This typically follows imaging studies such as X-rays, MRI, or CT scans, or direct visualization during arthroscopy.

• Ensure laterality is accurately documented (left toe).
• Distinguish from foreign body in soft tissue, which would use a T-code.
• Code any associated arthritis or other joint pathology separately.
