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

This code signifies a Colles' fracture, a specific type of distal radius fracture, affecting the right arm. It indicates that the fracture was initially an open fracture (Type I or II) and has subsequently healed in a misaligned or deformed position (malunion).

Use this code for follow-up encounters where a patient is being treated for complications arising from a malunited Colles' fracture of the right radius, which was originally an open fracture. This would include scenarios like pain, limited range of motion, or functional impairment due to the malunion.

• Ensure documentation clearly specifies "right radius" and "Colles' fracture" to differentiate from other distal radius fractures.
• Verify the original fracture was an "open fracture type I or II" and that "malunion" is explicitly documented.
• This code is for subsequent encounters; an initial encounter for the malunion would use a different code.
