Nondisp seg fx shaft of rad, l arm, 7thK

This code signifies a left arm radius fracture that involves a segment of the bone shaft, is not displaced, and has failed to heal properly after initial treatment. The "K" seventh character indicates that this is a follow-up visit for a closed fracture where nonunion is present.

Apply this code for patients presenting for ongoing management of a previously treated, non-displaced segmental shaft fracture of the left radius that has not united. This would include visits for evaluation of nonunion, planning for revision surgery, or conservative management of the nonunion.

• Ensure the documentation clearly specifies a segmental fracture of the radius shaft, not just a general shaft fracture.
• Verify the fracture is on the left arm and is explicitly documented as nondisplaced.
• Confirm the encounter is for a subsequent visit related to nonunion of a closed fracture.
