Summary
BCBS Mississippi has updated their policy on automated ambulatory blood pressure monitoring (ABPM) for diagnosing hypertension in patients with elevated office blood pressure. The policy specifies that 24-hour ABPM is medically necessary only for one-time testing to differentiate white coat hypertension from true hypertension, with specific criteria including office BP <180/110 mm Hg and no end-organ damage.
Action Required
Immediately: Review all ambulatory blood pressure monitoring claims to ensure they meet the updated medical necessity criteria - office BP must be <180/110 mm Hg with no hypertensive end-organ damage, and testing must be one-time only to differentiate white coat hypertension. Update prior authorization documentation requirements to include physical examination and laboratory testing results showing absence of end-organ damage. Repeated ABPM testing will be considered investigational and likely denied.
