Colles' fx r radius, subs for opn fx type I/2 w nonunion

This code describes a Colles' fracture, which is a specific type of distal radius fracture where the broken fragment of the radius tilts upward. In this instance, the fracture is on the right side, was initially an open fracture (Type I or II), and has failed to heal properly, resulting in a nonunion. This indicates a chronic healing complication requiring ongoing medical management.

Use this code for follow-up encounters when a patient with a previously diagnosed right Colles' fracture, which was initially an open fracture (Type I or II), is being treated for nonunion. This applies to situations where the fracture fragments have not united after an expected healing period, and the patient is receiving continued care for this complication.

• Ensure documentation clearly specifies "right" radius and "Colles' fracture."
• Verify the original fracture was an "open fracture type I or II" and that "nonunion" is explicitly documented.
• This code is for subsequent encounters; use an initial encounter code for the acute injury.
