Oth fracture of second lum vertebra, subs for fx w nonunion

This code signifies a fracture of the second lumbar vertebra, excluding compression or burst fractures, that has not healed properly and is being treated during a follow-up visit. The nonunion indicates a failure of the bone to mend completely after the initial injury.

Apply this code when a patient presents for ongoing management of a previously diagnosed, non-healing fracture of the L2 vertebra. This would include situations where surgical intervention for nonunion is being planned or has already occurred, or when conservative management for the nonunion is continuing.

• Ensure documentation clearly specifies "nonunion" and identifies the second lumbar vertebra.
• Verify that the encounter is for follow-up care of the fracture, not the initial treatment.
• Distinguish from malunion (improperly healed) and other specific L2 fracture types (e.g., compression, burst).
