Bent bone of left ulna, subs for clos fx w delay heal

This code indicates a fracture of the left ulna where the bone has healed in a bent or angulated position, and the patient is currently receiving follow-up care for delayed healing of this closed fracture. It signifies an ongoing treatment phase for a malunion or deformity resulting from the initial injury, where the healing process is taking longer than expected.

Use this code when a patient presents for a follow-up visit or continued treatment for a previously diagnosed closed fracture of the left ulna that has healed with a noticeable bend or angulation, and the healing process is still considered delayed. This applies to situations where the fracture site has not fully consolidated within the expected timeframe, and the patient is still under active management for this issue.

• Ensure documentation clearly specifies "left ulna" and "bent bone" or "angulated fracture" in the context of delayed healing.
• This code is for subsequent encounters; an initial encounter code would have been used for the acute fracture.
• Verify that the fracture is documented as "closed" to align with this specific code.
