Dislocation of L4/L5 lumbar vertebra, subsequent encounter

This code signifies a dislocation between the fourth and fifth lumbar vertebrae that is being addressed during a follow-up visit. It indicates that the initial injury has already been diagnosed and treatment is ongoing, or the patient is presenting for a scheduled re-evaluation of the previously dislocated segment.

Apply this code when a patient returns for subsequent care related to a previously diagnosed L4/L5 lumbar vertebral dislocation. This includes visits for cast changes, physical therapy, medication management, or monitoring of healing and stability after the initial treatment.

• Ensure documentation clearly specifies "subsequent encounter" for the L4/L5 dislocation.
• Always pair this code with an external cause code (V00-Y99) if the cause of the original dislocation is known and relevant to the current encounter.
• Do not use this code for the initial treatment of the dislocation; a code from the "initial encounter" category would be appropriate for that scenario.
