Have you Received Your Supplemental Medi-Cal Payments? September 21, 2018 General Cal, Medi Physicians should have received their supplemental payments by August 31 in both fee-for-service and Medi-Cal managed care when providing Medi-Cal services under certain CPT codes. These supplemental payments are being made from Prop 56 funds to increase access to care for Medi-Cal patients. Practices that have not received their supplemental payments should contact the plan or the delegated entity; to find out which to contact, physicians can refer to a list created by the California Medical Association (CMA) identifying who distributed the payments. Physicians can also obtain assistance by calling the CMA at (888) 401-5911.
