Colles' fx unsp radius, subs for clos fx w delay heal

This code signifies a Colles' fracture, which is a break in the distal radius, where the broken fragment of the radius tilts upward. This specific code is used when the fracture is closed (skin intact) and the patient is in a subsequent phase of care, experiencing delayed healing of the bone.

Apply this code for follow-up encounters where a patient with a previously diagnosed Colles' fracture of an unspecified radius is being treated for delayed union. This would include situations where the fracture is not healing at the expected rate, requiring continued management or intervention.

• Ensure documentation clearly states "delayed healing" for a closed Colles' fracture.
• Verify the encounter is subsequent, not initial or sequela.
• Do not use if the fracture is open or if healing is progressing normally.
