Oth fx low end r ulna, subs for opn fx type I/2 w delay heal

This code describes a fracture of the lower end of the right ulna that is not specifically classified as another type (e.g., Colles', Smith's). It indicates that the initial injury was an open fracture, classified as Type I or II, and the patient is now presenting for follow-up care due to delayed healing of that fracture.

Use this code for a patient presenting for a subsequent encounter for an open Type I or II fracture of the distal right ulna that is not healing at the expected rate. This would apply when the fracture site shows signs of delayed union or non-union, requiring ongoing medical management or intervention.

• Ensure documentation clearly specifies "other" fracture of the lower end of the ulna, not a more specific type.
• Verify the initial fracture was an open Type I or II and that the current encounter is for delayed healing.
• Always assign an external cause code (V00-Y99) to describe the circumstances of the injury, if not already documented.
