Unsp fx r low leg, subs for opn fx type I/2 w malunion

This code describes a situation where a patient has a right lower leg fracture, but the specific bone involved (tibia, fibula, or both) is not documented. This particular encounter is for follow-up care of an open fracture (where the skin was broken) that has healed incorrectly, resulting in a malunion.

Use this code when documentation indicates a right lower leg fracture, but the specific bone is not identified, and the patient is being treated for a malunion of an initial open fracture classified as Type I or II. This would typically be used during follow-up visits after the initial treatment of the fracture, once the malunion has been identified and is being managed.

• Ensure the documentation clearly states "right lower leg" and that the specific bone is not specified.
• Verify that the initial fracture was an open fracture, specifically Type I or II, and that the current issue is a malunion.
• This code requires a 7th character for the encounter type; "Q" indicates a subsequent encounter for a malunion.
