Displ seg fx shaft of ulna, l arm, 7thK

This code signifies a left ulnar shaft fracture that is both displaced and segmental, meaning the bone is broken into at least three pieces. The fracture has failed to heal properly (nonunion) and the patient is presenting for follow-up care or treatment related to this ongoing issue, with the fracture remaining closed (skin intact).

Apply this code when documenting a patient's visit for management of a previously diagnosed, displaced segmental fracture of the left ulnar shaft that has progressed to nonunion. This would include scenarios such as follow-up appointments for non-operative management of the nonunion, or pre-operative evaluation for surgical intervention to address the nonunion.

• Ensure documentation clearly specifies "left arm" and "ulna shaft" to differentiate from other forearm bones or locations.
• Confirm the fracture is explicitly described as "segmental" and "displaced" to support this specific code.
• The "K" seventh character indicates a subsequent encounter for a closed fracture with nonunion; verify the encounter type and nonunion status.
