Complete physeal arrest, left distal radius

This code signifies the premature and complete cessation of growth in the left distal radial physis (growth plate). This condition results in a permanent shortening of the left radius, potentially leading to ulnar positive variance and functional impairment of the wrist. It is typically a sequela of trauma, infection, or other growth plate disturbances.

Apply this code when documentation explicitly states a complete physeal arrest affecting the distal end of the left radius. This diagnosis is often confirmed by imaging studies (e.g., X-rays) showing a fused growth plate in a skeletally immature individual. Use for patients presenting with growth discrepancies or deformities related to this specific growth plate closure.

• Ensure documentation specifies "complete" arrest; partial arrest codes are distinct.
• Verify laterality (left) and bone (radius) and location (distal) are clearly stated.
• Consider coding any underlying cause (e.g., fracture, infection) as an additional diagnosis, if applicable.
