Oth fx upper end of unsp ulna, subs for clos fx w delay heal

This code signifies a fracture of the upper part of the ulna, where the specific location within the upper end is not documented. It indicates that the patient is in a subsequent phase of care for a closed fracture that is experiencing delayed healing.

Apply this code when a patient presents for follow-up treatment of an ulnar fracture that was initially closed, and the healing process is progressing slower than expected. This would be used after the initial encounter for the acute injury. It is appropriate when the medical record does not specify whether the fracture is of the olecranon or coronoid process.

• Ensure documentation clearly states "delayed healing" for a closed fracture.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
• Only use for "unspecified ulna" when a more specific location (e.g., olecranon, coronoid process) is not documented.
