Displ transverse fx r patella, subs for clos fx w nonunion

This code signifies a fracture of the right kneecap that runs across its width, where the bone fragments are no longer in their proper alignment. This specific encounter indicates that the fracture has not healed as expected (nonunion) and the treatment is ongoing, with the skin over the fracture remaining intact.

Use this code for follow-up encounters when a patient is receiving continued care for a displaced transverse fracture of the right patella that has failed to unite. This applies to situations such as ongoing conservative management, preparation for revision surgery, or monitoring of a nonunion without immediate surgical intervention.

• Ensure documentation clearly states "nonunion" and specifies the "right" patella and "transverse" fracture type.
• Verify that the encounter is for a "subsequent" visit and that the fracture is "closed."
• Do not use this code for initial treatment or for fractures that have healed.
