Oth fx r low leg, subs for opn fx type I/2 w nonunion

This code describes a situation where a patient has sustained an open fracture of the right lower leg, specifically of a type I or II severity, and is now presenting for follow-up care due to the fracture failing to heal properly (nonunion). The "other fracture" designation indicates it's not a specific type like a fibula or tibia shaft fracture.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed open right lower leg fracture (Type I or II) is being treated for a confirmed nonunion. This would include follow-up appointments, imaging studies, or procedures related to the ongoing management of the unhealed fracture.

• Ensure documentation clearly specifies "nonunion" and the "open" nature of the initial fracture.
• Verify the laterality is "right" and the anatomical site is "lower leg."
• Always sequence this code after the primary reason for the encounter, if applicable.
