Oth extrartic fx low end unsp rad, 7thM

This code signifies a non-healing fracture located at the lower end of the radius, outside of the joint capsule, where the specific side (left or right) is not documented. The initial injury was an open fracture, classified as Type I or II, and the patient is now being seen for follow-up care related to the nonunion.

Apply this code when a patient presents for ongoing management of a previously sustained open distal radius fracture (Type I or II) that has failed to heal properly, resulting in a nonunion. This is used for subsequent encounters after the initial treatment of the fracture.

• Ensure documentation clearly specifies "nonunion" and that the fracture was initially an "open fracture type I or II."
• This code is for an unspecified radius; if the laterality is known, a more specific code should be used.
• The 7th character "M" indicates a subsequent encounter for an open fracture with nonunion.
