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

This code signifies a fracture of the second lumbar vertebra where the specific type of fracture is not documented. It indicates that the patient is in a phase of treatment following the initial care, and the fracture has not healed properly, leading to a nonunion.

Apply this code when a patient presents for follow-up care of a previously diagnosed, unspecified L2 vertebral fracture that is now complicated by nonunion. This is appropriate for encounters focused on managing the persistent nonunion, such as evaluating for surgical intervention or monitoring conservative treatment for delayed healing.

• Ensure documentation clearly supports a nonunion status for the L2 vertebral fracture.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the fracture location is specifically the second lumbar vertebra.
