The bariatric surgeons at BASS Bariatric Surgery Center provide revision procedures only for patients whose original bariatric surgery was performed by our team. We do not perform revision surgeries for operations completed at outside hospitals or by other providers. This policy is in place to ensure patient safety and maintain the highest standard of care.
