Colles' fracture of r radius, subs for clos fx w nonunion

This code signifies a Colles' fracture, a specific type of distal radius fracture where the broken fragment tilts upward, affecting the right arm. The "subsequent encounter" indicates the patient is receiving follow-up care for this injury, and "nonunion" specifies that the bone fragments have failed to heal together after a typical healing period.

Use this code for patients presenting for ongoing management of a right Colles' fracture that has not healed properly. This includes scenarios like cast changes, physical therapy, or surgical planning for nonunion. It is appropriate when the initial fracture treatment has concluded, but the bone has not united.

• Ensure documentation clearly states "nonunion" for the right Colles' fracture.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use for malunion, which implies healing in an incorrect position, but rather for a complete failure to heal.
