Displ seg fx shaft of rad, l arm, 7thM

This code describes a left arm injury involving a radius shaft fracture that is both displaced and segmental, meaning the bone is broken into at least three pieces. This specific code is used when the patient is receiving follow-up care for an open fracture (where the bone broke through the skin) classified as Type I or II, and the fracture has failed to heal properly (nonunion).

Use this code for a patient presenting for ongoing treatment of a previously sustained open, displaced, segmental fracture of the left radial shaft, where the fracture is not uniting. This would include scenarios such as surgical intervention for nonunion, casting changes, or wound care related to the original open fracture, all in the context of the nonunion.

• Ensure documentation specifies "left arm" and "radius shaft" to support this code.
• Verify the fracture is explicitly documented as "displaced" and "segmental."
• Confirm the encounter is for "nonunion" of an "open fracture type I or II" and not initial or routine follow-up care for a healing fracture.
