Insurance-mandated weight management program before weight-loss surgery provides no clinical benefit

Many insurance companies require patients to complete a medically supervised weight management program before they approve them for weight-loss surgery, but new data shows this controversial requirement does nothing to improve treatment or safety outcomes, and may actually hinder weight loss success.

The study, presented here today at the American Society for Metabolic and Bariatric Surgery (ASMBS) Annual Meeting, adds to a growing body of evidence that calls into question the clinical rationale for delaying to fulfill this requirement imposed by insurers.

Weight management program requirements vary among insurers. Some require patients to simply complete a program; others expect patients to maintain weight within a defined period; others may deny payment for surgery if patients gain or even lose weight. The duration of these programs range from three to 12 months.

Many believe that participation in a weight management program preoperatively results in patients with fewer complications, better health outcomes and decreased healthcare costs.

"Believing is one thing, proving is another. Patients in the insurance-mandated weight management programs did not achieve greater weight loss before or after bariatric surgery, did not have fewer post-operative complications, and did not have better resolution of obesity-related diseases when compared to patients who had no such insurance requirement," said study-co-author Deborah Hutcheon, Doctor of Clinical Nutrition (DCN) and RD, Prisma Health, Greenville, SC. "The data shows the requirement only served to diminish outcomes and unnecessarily delay patient access to a life-saving medical intervention."

In the single-institution retrospective study, researchers reviewed the weight loss and safety outcomes of 1,056 patients who had either laparoscopic surgery (572) or sleeve gastrectomy (484) from 2014 to 2019. A total of 779 patients completed a medically supervised weight management program as mandated by their . Patients were followed for up to five years, which researchers note, to their knowledge, is the longest duration of follow-up to date for a study of this kind.

Patients not required to complete the weight management program prior to surgery had, on average, greater weight loss (1% to 5% more) in both the short- and long-term, and had better resolution or improvement of obesity-related diseases including hypertension, diabetes, and hyperlipidemia. No differences were seen in the rate of complications. However, weight management program patients who received gastric bypass had a significantly higher reoperation rate 13 months after surgery (3.8%), while gastric bypass patients who did not participate in the program did not require any reoperations.

Patients with the weight management program requirement waited an extra two months on average to have surgery, which researchers theorize may have resulted in a reduced long-term commitment to diet, exercise, and lifestyle modification after surgery, contributing to less weight loss.

In a 2016 position statement, the ASMBS called for an end to insurance mandated preoperative supervised weight loss requirements and mandates, stating, "The discriminatory, arbitrary, and scientifically unfounded practice of insurance-mandated preoperative weight loss contributes to patient attrition, causes unnecessary delay of lifesaving treatment, leads to the progression of life-threatening comorbid conditions, is unethical, and should be abandoned."

"Some insurers are following the data and discontinuing their mandates, but many still cling to the misguided assumption that requiring completion of a management program before bariatric improves results. There is simply no scientific basis to this assumption and this practice has to stop," said bariatric surgeon Teresa LaMasters, MD, ASMBS President-Elect, who was not involved in the study. "Every day delayed is another day denied access to the most effective long-term treatment for obesity. The preparation of the patient for metabolic rests with the surgeon in collaboration with a multidisciplinary team. Arbitrary barriers should not stand in the way of these life-saving procedures."
