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

This code signifies a Monteggia's fracture of the left ulna, specifically an open fracture of type I or II, that is currently in a phase of delayed healing. A Monteggia's fracture involves a fracture of the ulna with an associated dislocation of the radial head. The "open" designation indicates a break in the skin, and "delayed healing" means the fracture is not progressing to union at the expected rate.

Use this code for follow-up encounters where a patient is receiving ongoing treatment for a left ulnar Monteggia's fracture that was initially open (Type I or II) and is now exhibiting delayed healing. This would apply when the patient is seen for cast changes, wound care, physical therapy, or re-evaluation of the fracture's healing progress after the initial treatment phase.

• Ensure documentation clearly specifies "left ulna" and "Monteggia's fracture" with an "open" component (Type I or II).
• Confirm the encounter is for "subsequent" care and that "delayed healing" is explicitly documented by the provider.
• Do not use for initial treatment or for fractures healing normally.
