Oth fx upr end left rad, subs for opn fx type I/2 w nonunion

This code describes a situation where a patient has a non-healing fracture in the upper part of their left radius, specifically an open fracture of Type I or II, and is presenting for follow-up care. The fracture is not uniting as expected, indicating a complication in the healing process.

This code is appropriate for documenting subsequent encounters for patients with a previously diagnosed open fracture (Type I or II) of the proximal left radius that has failed to heal. This would include visits for ongoing management, evaluation of nonunion, or preparation for further intervention.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status.
• Verify the fracture type was initially documented as open Type I or II.
• Confirm the laterality is accurately recorded as "left" radius.
