We've advanced nearly $4.7B to providers in need and will continue to provide financial support to providers through full system recovery. Significant enhancements are available to providers who receive payments from payers processed by Change Healthcare; UnitedHealthcare medical, dental and vision providers; and providers who have exhausted all available connection options — or are in the process of implementing workaround solutions — and work with other payers who have opted not to advance funds while the Change systems are down.
