Oth fx shaft of r tibia, subs for opn fx type I/2 w malunion

This code describes a situation where a patient has experienced a fracture of the shaft of their right tibia, which was initially an open fracture (Type I or II), and is now presenting for follow-up care due to improper healing or alignment (malunion). It indicates that the initial injury involved a break in the skin, and the bone has not healed correctly.

Use this code for follow-up encounters when a patient with a previously diagnosed open fracture (Type I or II) of the right tibial shaft is being treated for malunion. This applies to situations where the fracture has healed in an unsatisfactory position, requiring further medical intervention or monitoring.

• Ensure documentation clearly specifies "malunion" and not "nonunion" (which has a different code).
• Verify the laterality (right tibia) and the type of initial open fracture (Type I or II).
• This code is for subsequent encounters; an initial encounter would use a different code.
