Longitudinal reduction defect of right radius

This code describes a congenital malformation where the right radius bone is abnormally shortened or absent along its longitudinal axis. This condition is a type of limb reduction defect affecting the forearm.

Assign this code when documentation explicitly states a longitudinal reduction defect of the right radius. This diagnosis is typically made at birth or early childhood based on physical examination and imaging studies like X-rays.

• Ensure the documentation specifies the right radius; separate codes exist for the left or bilateral involvement.
• Distinguish from transverse reduction defects, which involve a complete absence of the distal portion of the limb.
• Look for associated anomalies, as limb reduction defects can be part of broader syndromes, and code them separately if present.
