Nondisp seg fx shaft of ulna, unsp arm, 7thJ

This code describes a patient presenting for follow-up care of a non-displaced fracture involving a segment of the ulnar shaft. The initial injury was an open fracture, classified as Type IIIA, IIIB, or IIIC, and the current encounter indicates that the healing process is delayed.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed open segmental ulnar shaft fracture (Type IIIA, IIIB, or IIIC) is experiencing delayed union. It signifies ongoing management of the fracture's healing, not the initial treatment. This code would be used when the patient is seen for assessment of healing progress, wound care related to the open nature of the original fracture, or adjustments to the treatment plan due to the delayed healing.

• Ensure documentation clearly specifies "delayed healing" for the subsequent encounter.
• Verify the original fracture was indeed an open segmental fracture of the ulnar shaft, classified as Type IIIA, IIIB, or IIIC.
• This code requires a 7th character "J" for subsequent encounter with delayed healing.
