Colles' fx r radius, subs for opn fx type 3A/B/C w nonunion

This code signifies a Colles' fracture, which is a break in the distal radius with dorsal displacement, specifically affecting the right arm. The fracture is an open type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and bone exposure. The "subsequent encounter" aspect denotes that the patient is receiving follow-up care for a nonunion, meaning the fracture has failed to heal properly after an initial treatment.

Apply this code when documenting ongoing treatment for a right Colles' fracture that was initially open (type IIIA, IIIB, or IIIC) and has now developed a nonunion. This would be used for subsequent visits where the focus is on managing the nonunion, such as further surgical intervention, bone grafting, or prolonged immobilization. Do not use for the initial treatment of the fracture.

• Ensure documentation clearly specifies "right" radius and "Colles' fracture" for accurate laterality and fracture type.
• Verify the open fracture type (IIIA, IIIB, or IIIC) is explicitly stated in the medical record.
• Confirm the encounter is for a "subsequent" visit addressing a "nonunion" to differentiate from initial treatment or routine healing.
