Unsp fx upper end of l ulna, subs for clos fx w delay heal

This code signifies a fracture of the upper portion of the left ulna where the specific type of fracture is not documented. The patient is in a subsequent phase of care, and the fracture, though closed, is exhibiting delayed healing.

Apply this code when a patient presents for follow-up care of an unspecific left proximal ulnar fracture that was initially treated conservatively or surgically, and imaging or clinical assessment indicates the bone is not healing at the expected rate. This would be used for encounters such as cast changes, physical therapy, or re-evaluation appointments during the delayed healing period.

• Ensure documentation specifies "left" ulna and "upper end" or "proximal" ulna.
• Confirm the fracture is closed and the encounter is for delayed healing, not initial treatment or routine follow-up for a healing fracture.
• Always sequence this code after the primary reason for the encounter if applicable (e.g., physical therapy code).
