Oth fx shaft of unsp ulna, subs for clos fx w routn heal

This code signifies a follow-up visit for a patient who sustained a non-specific fracture of the shaft of an unidentifiable ulna, where the fracture is closed and healing normally. It indicates that the initial treatment has been rendered and the patient is now in the routine recovery phase.

Apply this code for subsequent encounters when a patient with a previously diagnosed closed ulnar shaft fracture is presenting for routine follow-up, cast checks, or physical therapy during the expected healing period. This is appropriate when there are no complications or delayed healing noted.

• Ensure documentation specifies "subsequent encounter" and "routine healing" for a closed fracture.
• Confirm the fracture location is the shaft of the ulna, but the specific side (left/right) is not documented.
• Do not use for initial treatment, nonunion, malunion, or delayed healing; those require different seventh characters.
