Smith's fracture of unsp radius, subs for clos fx w nonunion

This code signifies a Smith's fracture, a specific type of distal radius fracture where the distal fragment is displaced volarly (anteriorly). The "unspecified radius" indicates that the laterality (left or right) of the fracture is not documented. The "subsequent encounter for closed fracture with nonunion" specifies that the patient is receiving follow-up care for a fracture that has failed to heal properly and the skin remains intact over the fracture site.

This code is appropriate when a patient presents for ongoing management of a previously diagnosed Smith's fracture of the radius that has not united. This includes scenarios where the patient is undergoing conservative treatment, surgical intervention, or evaluation for nonunion. It should be used for follow-up visits after the initial treatment of the fracture.

• Ensure documentation clearly states "Smith's fracture" and "nonunion" for accurate code assignment.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• If laterality (left or right) is documented, a more specific code should be chosen.
