Disp fx of nk of l rad, subs for opn fx type I/2 w nonunion

This code signifies a nonunion of a previously treated open fracture of the neck of the left radius, specifically an open fracture type I or II. Nonunion indicates that the bone has failed to heal completely after a prior surgical or non-surgical intervention.

This code is appropriate for follow-up encounters where a patient is being treated for a nonunion of a left radial neck fracture that was initially an open fracture of Gustilo-Anderson type I or II. It should be used when documentation confirms the fracture has not healed and further management for the nonunion is being provided.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for treatment.
• Verify the original fracture was an "open fracture type I or II" of the left radial neck.
• Do not use for initial encounters or for malunion, which is a different complication.
