Unsp physeal fx upper end radius, right arm, sequela

This code indicates a long-term complication or late effect stemming from an unspecified fracture of the growth plate at the top of the right radius bone. The original injury occurred in the past, and the patient is now presenting with a residual problem directly attributable to that fracture.

Use this code when documenting a patient presenting for treatment of a chronic issue, such as growth disturbance, deformity, or persistent pain, that is a direct result of a previously sustained, unspecified physeal fracture of the proximal right radius. This code is appropriate when the acute phase of the original fracture has passed, and the current encounter addresses the sequelae.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., M21.021 for valgus deformity of right forearm).
• Ensure documentation clearly links the current condition to the prior physeal fracture of the right radius.
• The "S" seventh character indicates sequela and should only be used for encounters addressing the late effects of the injury.
