Other fracture of shaft of radius, unspecified arm, subsequent encounter for closed fracture with nonunion

📋Clinical Description

This code signifies a fracture of the main part (shaft) of the radius bone in an unspecified arm, which has not healed properly (nonunion) and is being treated in a subsequent encounter. The skin over the fracture site remains intact (closed fracture).

🎯When to Use

Apply this code when a patient presents for follow-up care of a previously diagnosed closed radial shaft fracture that has failed to unite. This includes situations where the patient is undergoing further conservative management, surgical intervention for nonunion, or evaluation of the nonunion.

💡Coding Tips

Confirm the encounter is for follow-up care of the nonunion, not the initial injury.
Ensure documentation specifies "closed fracture" and "nonunion" of the radial shaft.
Do not use for malunion, which has a separate code.
