Abstract

Background

For patients who wish to undergo bariatric surgery, variation in pre-operative insurance requirements may represent inequity across insurance plan types. We conducted a cross-sectional assessment of the variation in pre-operative insurance requirements.

Methods

Original insurance policy documents for pre-operative requirements were obtained from bariatric surgery programs across the entire USA and online insurance portals. Insurance programs analyzed include commercial, Medicaid, and Medicare/TriCare plans. Poisson regression adjusting for U.S. Census region was used to evaluate variation in pre-operative requirements. Analyses were done at the insurance plan level. Our primary outcome was number of requirements required by each plan by insurance type. Our secondary outcome was number of months required to participate in medically supervised weight loss (MSWL).

Results

Among 43 insurance plans reviewed, representing commercial (60.5%), Medicaid (25.6%), and Medicare/TriCare (14.0%) plans, the number of pre-operative requirements ranged from 1 to 8. Adjusted Poisson regression showed significant variation in pre-operative requirements across plan types with Medicaid-insured patients required to fulfill the greatest number (4.1, 95%CI 2.7 to 5.4) compared to 2.7 (95%CI 2.2 to 3.2, P = 0.028) for commercially insured patients and 2.1 (95%CI 1.1 to 3.1, P = 0.047) for Medicare/TriCare-insured patients. Medicaid-insured patients were also required to complete a greater number of months in MSWL (6.6, 95%CI 5.5 to 7.6) compared to commercially (3.8, 95%CI 2.9 to 4.8, P < .001) and Medicare/TriCare-insured patients (1.7, 95%CI 0.3 to 3.0, P = .001).

Conclusion

The greater frequency of pre-operative requirements in Medicaid plans compared to Medicare/TriCare and commercial plans demonstrates inequity across insurance types which may negatively impact access to bariatric surgery. Pre-operative insurance requirements must be reevaluated and standardized using established evidence to ensure all individuals have access to this life-saving intervention.
