Displ spiral fx shaft of ulna, l arm, 7thJ

This code signifies a left ulnar shaft fracture, specifically a displaced spiral type, that was initially an open fracture (Type IIIA, IIIB, or IIIC) and is now experiencing delayed healing. The "subsequent encounter" indicates the patient is receiving ongoing care for the fracture after the initial treatment phase.

Apply this code for follow-up visits where a patient with a previously diagnosed open, displaced spiral fracture of the left ulnar shaft is being managed for delayed union or nonunion. This includes scenarios where additional interventions, such as bone grafting or revision surgery, are being considered or performed due to the slow healing process.

• Ensure documentation clearly specifies "left arm" and "ulna" to differentiate from radial or other arm fractures.
• Verify the initial fracture was classified as an open fracture type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; an initial encounter code would be used for the acute injury.
