Displ longitud fx l patella, 7thQ

This code describes a malunion of a displaced longitudinal fracture of the left patella that was initially an open fracture of Gustilo type I or II. Malunion indicates that the fracture has healed, but in an unsatisfactory position, leading to functional impairment or deformity.

This code is appropriate for encounters where a patient is being treated for complications arising from a malunited, previously open, displaced longitudinal fracture of the left patella. This includes follow-up visits, evaluations for corrective surgery, or management of ongoing symptoms related to the malunion.

• Confirm the fracture was initially an open fracture (Type I or II) and has healed in a malunited position.
• Ensure the encounter is for the sequela of the malunion, not the initial healing phase.
• Always verify laterality (left patella) and fracture type (longitudinal, displaced).
