Blue Cross Vermont's preventive care benefit covers the screenings, vaccines, medications and counseling it lists at no cost when they align with the USPSTF, ACIP, HRSA and Vermont recommendations, and it lists the CPT, HCPCS and ICD-10-CM codes that qualify. Several revisions are already in effect: obstetric professional care after 09/01/2026 is billed with an E/M code and modifier -TH, branded oral contraceptives can only be dispensed when no commercially available generic equivalent exists, and the adult mammography, breast ultrasound and breast MRI sections added diagnosis codes including N63.15, N63.25 and Z12.31 effective 08/01/2026. Other revisions add pre-diabetes preventive interventions, a weight loss behavioral intervention section, influenza code 90616 to the adult vaccine section, diabetes screening age banding changed from 40 to 35, and pregnancy diagnosis codes with a 12/01/2026 effective date.
This policy covers bariatric surgery for morbid obesity in group contracts that include a weight management or obesity treatment benefit. Surgery is covered for patients at least 18 years old who meet the BMI criteria (40 or greater, or 35 or greater with hypertension, diabetes or hyperlipidemia, or at least 100 pounds or twice the ideal weight), have had morbid obesity for at least five years, have documented failed weight loss attempts, and have no treatable metabolic cause such as adrenal or thyroid disorders. Covered procedures include open and laparoscopic gastric bypass with a Roux-en-Y limb of 150 cm or less, adjustable gastric banding, sleeve gastrectomy, and biliopancreatic bypass with duodenal switch for BMI of 50 or greater, while the most recent review dated 07/01/2026 kept the policy statements unchanged and removed ICD-9 codes from the code reference.
Aetna considers clinician-supervised weight reduction counseling for adults with a BMI of 30 or greater medically necessary up to a combined limit of 26 individual or group visits by any recognized provider per 12-month period. The FDA-cleared Plenity device is considered medically necessary to aid weight management in overweight and obese adults with a BMI of 25 to 40 kg/m2 when used with diet and exercise. For very low calorie diets (less than 799 kcal/day) in obese members, the listed EKG, lipid profile and chemistry tests are covered for up to 16 weeks, while exercise programs, special diet supplements, hospital confinement for a weight reduction program, and many experimental interventions such as wearable devices and sodium-glucose co-transporter 2 inhibitors are not covered or are considered experimental, investigational, or unproven for weight reduction.
