UnitedHealthcare Community Plan of North Carolina's November 2026 Medicaid medical policy update for Bariatric Surgery removed CPT 43882 from the applicable codes list. The update also notes that CPT codes 43659, 43772, 43889, 43999, and 64999 are not on the State of North Carolina Medicaid Fee Schedule and therefore may not be covered by the North Carolina Medicaid Program. Practices should update charge entry and claim edits for these codes for North Carolina Community Plan members.
Effective February 1, 2026, PacificSource is implementing new prior authorization requirements for Medicare and Medicaid. Medicare adds 20 procedure codes requiring prior auth (including arthroscopy, unlisted procedures, and specialized diagnostics) plus 3 codes requiring prior auth only when claims exceed $500. Medicaid adds 2 codes requiring prior auth. Billing teams must update systems and verify all affected codes before service delivery to avoid claim denials.
Arkansas Blue Cross expanded coverage for bariatric surgery to include Single anastomosis duodeno-ileal (SADI) bypass with sleeve gastrectomy (CPT 43659) under restricted criteria. Additionally, six medical policies covering various treatments will be archived, meaning these services will no longer have specific coverage guidelines.
Medical Policy SUR58, Bariatric Surgery, has an effective date of February 1, 2026. Bariatric surgery may be considered medically necessary for obesity when the patient has a BMI of 40 or greater, or a BMI of 35 or greater with type II diabetes, poorly controlled hypertension despite optimal medical management, coronary artery disease, or obstructive sleep apnea with an AHI of 15 or more per hour, and the patient is 18 or older (or under 18 with Tanner 4 or 5 development and the pediatric BMI thresholds in the policy). Patients must have at least 3 consecutive months of active participation in a structured, medically supervised pre-operative program within the 12 months before the surgery request, and a preoperative evaluation by a licensed psychologist, psychiatrist, LCSW/LICSW, licensed masters-level counselor or PMHNP must document the absence of significant psychopathology. Medically necessary procedures are a stand-alone sleeve gastrectomy, gastric bypass with a Roux-en-Y anastomosis and an alimentary limb of 150 cm or less, and biliopancreatic bypass with duodenal switch for patients 18 or older with a BMI of 50 or greater; vertical banded gastroplasty and adjustable gastric banding are not medically necessary, and distal gastric bypass, mini-gastric bypass, endoscopic bariatric procedures, gastric plication and two-stage procedures are investigational.
Gastric electrical stimulation is considered investigational for gastroparesis of diabetic, idiopathic, or post-surgical etiology. It is also considered investigational for the treatment of obesity. For State Health Plan members, gastric pacing is considered medically necessary for chronic gastroparesis when the diagnosis is confirmed by gastric emptying scintigraphy and nausea and vomiting are refractory to medical management.
