Oth fx of low end r rad, subs for opn fx type I/2 w nonunion

This code describes a situation where a patient has experienced a fracture in the lower part of their right radius, and this fracture was initially an open fracture of type I or II. The current encounter is for follow-up care due to the fracture failing to heal properly (nonunion).

This code is appropriate for documenting subsequent visits for a patient with a previously diagnosed open fracture (Type I or II) of the distal right radius that has not united. It should be used when the primary focus of the encounter is managing the nonunion of this specific fracture.

• Ensure the initial fracture was indeed an open fracture, type I or II, of the lower right radius.
• Verify that the current encounter is for the management of nonunion, not initial treatment or routine follow-up of a healing fracture.
• Always sequence this code after any codes for complications or specific treatments related to the nonunion.
