Unsp fx shaft of l femr, subs for opn fx type I/2 w malunion

This code describes a situation where a patient has experienced an unspecified fracture of the shaft of their left femur, which was an open fracture (Type I or II), and is now presenting for follow-up care due to malunion of that fracture. Malunion indicates that the fracture has healed, but in an unsatisfactory position or alignment.

Use this code for a patient who has previously been treated for an open fracture (Type I or II) of the left femoral shaft and is now being seen for complications related to the bone healing incorrectly. This applies to subsequent encounters where the primary focus is addressing the malunion.

• Ensure the documentation clearly specifies malunion as the complication of the previously open fracture.
• Verify that the fracture was explicitly documented as an open fracture, Type I or II, at the initial encounter.
• This code is for subsequent encounters, not the initial treatment of the fracture.
