Background:
Insurance-mandated precertification requirements are barriers to bariatric surgery. The value of their prescription, based on insurance type rather that the clinical necessity, is unclear.
Objectives:
To determine whether there is an association between insurance-mandated precertification criteria for bariatric surgery and short-term inpatient healthcare utilization.
Setting:
Pennsylvania Health Care Cost Containment Council's inpatient care databases for the years 2016-2017.
Methods:
The study included 2717 adults who underwent bariatric surgery in Southeastern Pennsylvania in 2016. Postoperative length of stay and rehospitalizations for these individuals were followed using clinical and claims data during the first year after bariatric surgery.
Results:
The requirements for 3- to 6-month preoperative medical weight management, as well as pulmonology and cardiology examinations, were not associated with the patient length of stay, number of all-cause rehospitalizations, or number of all-cause rehospitalization days after adjusting for patient age, sex, race, ethnicity, the Elixhauser comorbidity score, type of the surgery, facility where the surgery was performed, primary payer type, and the estimated median household income. Among commercially insured individuals (n = 1499), the mean number of all-cause rehospitalizations during the study period was lower in patients with no medical weight management requirement by a factor of .57 (lower by 43.1%; 95% confidence interval, .35-.94, P = .03) and higher in patients with no requirement for preoperative cardiology and pulmonology evaluations by a factor of 2.09 (95% confidence interval 1.09-4.02, P = .03).
Conclusion:
The findings suggest that the precertification requirement for preoperative medical weight management is not associated with a reduction in inpatient healthcare utilization in the first postoperative year.
