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

This code signifies a fracture of the lower portion of the left ulna, which is not further specified as a particular type of fracture (e.g., transverse, oblique). The fracture was initially 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 specific injury.

Apply this code when documenting a patient visit for ongoing management of a left distal ulna fracture that was initially open (Type I or II) and is now exhibiting a slower-than-expected healing process. This would be used for subsequent encounters after the initial treatment of the acute fracture.

• Ensure documentation clearly specifies the left ulna and the "subsequent encounter" for delayed healing.
• Verify the original fracture was indeed an open fracture, Type I or II, as this is a key component of the code.
• Do not use for initial encounter or for fractures that are healing normally.
