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

This code indicates a fracture of the lower portion of the left ulna, where the specific type of fracture is not documented. It signifies that the patient is in a subsequent phase of care for this injury, and the fracture, which was initially closed (skin intact), is now experiencing delayed healing.

This code is appropriate for follow-up encounters when a patient with a previously diagnosed, unspecified closed fracture of the distal left ulna is presenting with evidence of delayed bone union. This would typically be used after the initial treatment phase, such as during cast changes, physical therapy, or follow-up imaging that reveals persistent non-union or slow healing.

• Ensure documentation clearly states "delayed healing" for a closed fracture of the lower left ulna.
• Verify laterality (left) and the specific bone (ulna) are accurately documented.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
