Unsp fx upr end l rad, 7thN

This code signifies a non-healing fracture of the upper part of the left radius, specifically an open fracture of severe type (IIIA, IIIB, or IIIC). "Nonunion" indicates that the bone fragments have failed to heal completely after a significant period. This code is used for follow-up care after the initial treatment of the fracture.

Apply this code for patients presenting for ongoing management of a previously diagnosed open fracture of the proximal left radius that has not united. This includes situations where surgical intervention for nonunion is being planned or has already occurred, and the patient is in a subsequent phase of care.

• Always ensure documentation specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify laterality (left radius) is clearly documented.
• This code is for subsequent encounters; an initial encounter for the same fracture would use a different code.
