Oth fx of low end unsp rad, 7thN

This code describes a non-healing fracture of the lower end of the radius, where the bone has broken through the skin (an open fracture of severe type IIIA, IIIB, or IIIC). The "subsequent encounter" indicates that the patient is receiving follow-up care for this previously diagnosed injury, which has failed to unite. The "unspecified radius" denotes that the laterality (left or right) of the fracture is not documented.

Use this code for follow-up visits where a patient is being treated for a severe open fracture of the distal radius that has not healed. This applies when the physician is managing the nonunion of the fracture, such as for ongoing wound care, assessment for bone grafting, or preparation for revision surgery. It is appropriate when the medical record does not specify whether the fracture occurred on the left or right arm.

• Always confirm the fracture type (open IIIA, IIIB, or IIIC) and the nonunion status from the physician's documentation.
• Ensure the encounter is for follow-up care of the nonunion, not the initial treatment or routine healing.
• If laterality is documented (left or right radius), a more specific code should be selected.
