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

This code signifies a fracture of the first lumbar vertebra that is not healing properly, and the patient is presenting for follow-up care related to this ongoing issue. Nonunion indicates that the bone fragments have failed to unite after a sufficient healing period, requiring continued medical management.

Apply this code when documenting a patient encounter for ongoing treatment of a previously diagnosed L1 vertebral fracture that has been confirmed as a nonunion. This would include visits for pain management, imaging studies to assess nonunion progression, or discussions regarding surgical intervention for the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the first lumbar vertebra.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use for malunion, which implies healing in an unsatisfactory position.
