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

This code signifies a follow-up encounter for a left ulna shaft fracture that is not further specified as open or closed, and is healing routinely. The fracture is located in the main body of the ulna bone, distinct from the ends. This stage indicates the patient is progressing through the normal healing process for a closed fracture.

Use this code for subsequent visits where a patient is being monitored for a previously diagnosed closed fracture of the shaft of the left ulna, and the healing is proceeding as expected without complications. This would apply to routine follow-up appointments after initial treatment, such as cast checks or X-ray evaluations confirming satisfactory bone union.

• Ensure the encounter is for a subsequent visit, not the initial treatment.
• Verify the fracture is of the ulna shaft and on the left side.
• Confirm that healing is routine and there are no documented complications or delayed healing.
