Nondisp transverse fx shaft of unsp ulna, 7thJ

This code describes a fracture of the ulna's shaft that runs perpendicular to the bone's long axis, without any displacement of the bone fragments. It specifically indicates an open fracture (where the bone breaks through the skin) of a severe nature (Type IIIA, IIIB, or IIIC) that is not healing as expected. The "subsequent encounter" aspect signifies that this code is used for follow-up care after the initial treatment.

Use this code for patients presenting for ongoing management of a previously treated open transverse ulnar shaft fracture that is demonstrating delayed healing. This would include scenarios where the patient is receiving continued wound care, bone stimulation, or other interventions due to the slow progression of bone union. It is appropriate for follow-up visits after the initial surgical or non-surgical management.

• Ensure documentation clearly specifies "delayed healing" for an open fracture type IIIA, IIIB, or IIIC.
• Verify the fracture is specifically of the ulnar shaft and is transverse and nondisplaced.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
