UnitedHealthcare began mailing Medical Loss Ratio (MLR) premium rebate checks to eligible groups starting mid-September 2024. These rebate checks are sent to comply with the Affordable Care Act, which requires insurers to spend a minimum percentage of premium dollars on medical services and quality improvements. Eligible groups include small and large group markets as well as individual aggregation sets, with total rebate amounts in the hundreds of millions. For more details or questions, brokers and customers can contact UnitedHealthcare's dedicated service lines. In addition to rebate checks, UnitedHealthcare offers various digital tools for providers to access claims, billing, and payment information, including electronic fund transfers and virtual card payments for claim payments. If looking for a specific type of check like refund or rebate checks from UnitedHealthcare, verifying eligibility and contacting the provider's service line or using the provider portal is recommended for detailed status and information.
