Oth fx shaft of left ulna, subs for clos fx w delay heal

This code signifies a fracture of the shaft of the left ulna that is not further specified as comminuted, segmental, or simple, and is currently in a phase of delayed healing. The fracture was initially closed, meaning there was no break in the skin. The patient is receiving ongoing care for this specific injury.

Use this code when documenting follow-up care for a patient with a left ulnar shaft fracture that is not healing at the expected rate. This applies to situations where the fracture was initially closed and the patient is presenting for subsequent treatment, such as cast changes, physical therapy, or imaging to monitor healing progress.

• Ensure documentation clearly states "delayed healing" for the left ulnar shaft fracture.
• Verify the encounter is subsequent to the initial treatment of the closed fracture.
• Confirm the fracture location is specifically the shaft of the ulna and on the left side.
