Monteggia's fx r ulna, subs for opn fx type I/2 w delay heal

This code signifies a Monteggia's fracture involving the right ulna, which is a specific type of forearm fracture characterized by a fracture of the ulna and dislocation of the radial head. The "subsequent encounter" indicates that the patient is receiving follow-up care for this injury, and "open fracture type I or II" specifies that the skin was broken, exposing the bone, but with minimal to moderate soft tissue damage. "Delayed healing" further clarifies that the bone is not mending at the expected rate.

Apply this code when documenting follow-up care for a patient with a previously diagnosed open Monteggia's fracture of the right ulna (Type I or II) who is experiencing delayed union or non-union. This would be used during clinic visits, physical therapy sessions, or other encounters where the focus is on managing the ongoing healing process of this specific injury.

• Ensure documentation clearly specifies "delayed healing" for the Monteggia's fracture.
• Verify the laterality (right ulna) and the open fracture type (I or II) are explicitly stated in the medical record.
• Do not use this code for initial treatment or for fractures that are healing normally.
