The Case Against Bariatric Surgery Centers of Excellence
Edward H. Livingston, MD, FACS, AGAF
Professor and Chairman, Division of Gastrointestinal Surgery University of Texas Southwestern School of Medicine-DallasContributing Editor, JAMA
History
• Highly publicized bad outcomes
• Insurers pulled out of the market
• CMS MCAC 2004
• ASMBS asks for CMS NCD 2005– Offer COE requirement that they would
administer through SRC
Were COEs necessary?
• Bariatric surgery mortality and morbidity steadily decreasing
• Associated with greater acceptance for these operations and referral of lower risk candidates
• There was no outcomes crises requiring regulation of bariatric surgery
Argument: Insurers will not cover bariatric surgery
• True but not because of bad outcomes
• Bad outcomes occurred but current COEs do not address these matters
• Reticence to cover bariatric results from inadequate data to support the use of bariatric surgery
Bariatric Surgery Evidence
• Cause weight loss: Level 1
• Cause complications: Level 1
• Improve comorbidities: Level 2 and below
• The greatest risk to bariatrics is the low quality of evidence to support its use.
• Few ongoing studies will overcome this limitation
Evidence
• VA/DOD Obesity treatment CPG

II-2 Poor I
* Evidence quality was rated as fair, because few studies reported these outcomes consistently, and few studies were designed to examine the impact of surgery on these outcomes. **Adverse Events and need for reoperation.QE = Quality of Evidence; R = Recommendation (see Appendix A)

Why would insurance companies support COEs?
• Quality?• Cost?• How can they best limit bariatric surgery?
– Not cover it at all• Works for some but they are selling insurance products in a
competitive market
– Make it difficult to attain• Arbitrary requirements (pre op weight loss)
– Get surgeon buy in to make it difficult• COE
