Oth fracture of left acetabulum, subs for fx w nonunion

This code signifies a fracture of the left acetabulum that is not further specified as a particular type (e.g., anterior wall, posterior column) and is currently in a state of nonunion. Nonunion indicates that the bone has failed to heal completely after a prolonged period, requiring ongoing medical attention.

This code is appropriate for encounters where a patient is receiving treatment for a previously diagnosed, unspecified fracture of the left acetabulum that has not healed. This includes follow-up visits, surgical interventions to address the nonunion, or management of complications arising from the unhealed fracture.

• Ensure documentation clearly states "nonunion" and specifies the left acetabulum.
• Verify that the fracture type is not more specifically documented (e.g., anterior wall, posterior column) before using an "other specified" code.
• This code is for subsequent encounters; an initial encounter for the same fracture would use a different seventh character.
