Barton's fx left rad, subs for opn fx type I/2 w delay heal

This code signifies a specific type of distal radius fracture, known as a Barton's fracture, affecting the left arm. It indicates that the fracture is an open fracture (meaning the skin was broken) of either Type I or Type II severity, and the patient is currently in a phase of delayed healing.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed open Barton's fracture of the left radius (Type I or II) is experiencing a slower-than-expected healing process. It should be used when the patient is still receiving active treatment for the delayed union, such as cast changes, wound care, or monitoring for complications.

• Ensure documentation clearly specifies "delayed healing" and not nonunion or malunion, which have different codes.
• Verify the fracture type (Barton's) and laterality (left radius) are explicitly stated in the medical record.
• Confirm the open fracture type (I or II) was documented at the initial encounter or subsequent visits.
