Wedge comprsn fx fifth lum vertebra, subs for fx w nonunion

This code describes a specific type of spinal fracture affecting the fifth lumbar vertebra, where the vertebral body has collapsed in a wedge shape. Importantly, this code indicates that the fracture has not healed properly (nonunion) and the patient is presenting for follow-up care or treatment related to this ongoing issue.

This code is appropriate for subsequent encounters when a patient is being managed for a previously diagnosed wedge compression fracture of the L5 vertebra that has failed to unite. This includes visits for pain management, imaging follow-up to assess nonunion, or discussions regarding surgical intervention for the nonunion. It should be used when the patient is no longer in the initial healing phase.

• Always confirm the specific vertebra (L5) and fracture type (wedge compression) from the documentation.
• Ensure the documentation clearly states "nonunion" and that the encounter is "subsequent" for the fracture.
• Do not use this code for initial treatment of the fracture or for malunion, which is a different complication.
