My doctor did a Bilateral T12, L1 Kyphoplasty We billed cpt 22513 For the Thoracic and 22514 for the Lumbar. 22514 got denied for not being covered. I am wondering if we should have just billed the add on code 22515 which is for Thoracic or Lumbar instead 22514 which was for the lumbar. Does anyone know the correct way to bill.
