Stress fracture, right radius, subs for fx w nonunion

This code signifies a stress fracture of the right radius that has failed to heal properly, indicating a nonunion. The patient is currently receiving active treatment for this nonunion, rather than initial care or follow-up after successful healing.

Apply this code when documentation specifies a stress fracture of the right radius with nonunion, and the patient is undergoing ongoing treatment for this complication. This includes scenarios like surgical intervention for nonunion, casting, or other active management to promote healing of the ununited fracture.

• Ensure documentation explicitly states "nonunion" of the stress fracture, not just delayed healing.
• The 7th character "K" indicates a subsequent encounter for a fracture with nonunion; do not use for initial treatment or routine follow-up after healing.
• Verify laterality (right radius) is clearly documented to support this specific code.
