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

This code indicates a fracture of the lower end of the ulna that is not specifically categorized as another type (e.g., Salter-Harris, Colles', etc.), and the specific side (left or right) is not documented. It is used when the patient is receiving follow-up care for a closed fracture that is healing as expected.

Apply this code for subsequent encounters where a patient is being monitored for a non-specific, closed fracture of the distal ulna, and the healing process is routine. This would include follow-up appointments for cast changes, X-ray evaluations confirming callus formation, or general progress checks during the healing phase.

• Ensure documentation specifies "subsequent encounter" and "routine healing" for a closed fracture.
• Verify that the fracture location is the "lower end of the ulna" and no more specific fracture type is identified.
• If the laterality (left or right) is known, a more specific code should be used.
