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

This code signifies a wedge-shaped compression fracture affecting an unspecified lumbar vertebra that has failed to heal properly. The patient is presenting for ongoing treatment or evaluation of this non-healing fracture, indicating a subsequent encounter.

Apply this code when a patient is seen for follow-up care, management of complications, or continued treatment of a previously diagnosed lumbar wedge compression fracture that has been documented as a nonunion. This includes scenarios where surgical intervention for nonunion is being planned or has already occurred, and the patient is in a subsequent phase of care.

• Ensure documentation clearly states "nonunion" of the fracture.
• Verify that the encounter is not the initial treatment for the fracture.
• Confirm the fracture morphology is "wedge compression" and the location is lumbar, even if unspecified to a specific lumbar segment.
