Unsp fx shaft of left ulna, subs for clos fx w delay heal

This code signifies an unspecific break in the main part (shaft) of the left forearm bone (ulna) that is not open to the environment. It is used when the patient is receiving follow-up care for this fracture, and the healing process is taking longer than expected, but the fracture has not yet united.

Apply this code for a patient presenting for a follow-up visit for a closed left ulnar shaft fracture that was previously diagnosed, and the physician documents delayed union or non-progression of healing. This is appropriate when the initial treatment has been rendered and the patient is in the healing phase, but the bone is not mending at the anticipated rate.

• Ensure documentation specifies "left ulna" and "shaft" to differentiate from other forearm bones or ulnar fracture locations.
• The "G" seventh character indicates a subsequent encounter for a closed fracture with delayed healing; verify the healing status is explicitly documented as delayed.
• Do not use for initial treatment or for fractures that are healing normally.
