Barton's fx left rad, subs for opn fx type 3A/B/C w nonunion

This code describes a specific type of distal radius fracture, known as a Barton's fracture, affecting the left arm. It indicates that the fracture is an open fracture (meaning the skin was broken) of a severe nature (Type IIIA, IIIB, or IIIC) and that the bone fragments are failing to heal together properly after initial treatment.

Use this code when documenting a patient presenting for follow-up care of a previously treated open Barton's fracture of the left radius, where nonunion has been identified. This applies to situations where the patient is receiving ongoing management for the non-healing fracture, such as further surgical intervention, bone grafting, or prolonged immobilization.

• Ensure documentation clearly specifies "left radius" and "Barton's fracture."
• Verify that the fracture was initially open and classified as Type IIIA, IIIB, or IIIC.
• Confirm that the encounter is for subsequent care and that nonunion is explicitly documented.
