Since 1990, MOASC has represented more than 350 oncologists in California and neighboring states. Our association has succeeded in affecting payer policy and helped our members understand how to bill more efficiently and collect payments for the services they have been appropriately rendering to their patients. MOASC meets with the various payers, i.e. Medicare (Palmetto), California Department of Health Services, and EDS (Medi-Cal), Blue Cross of California, and Blue Shield of California. In this regards, we have succeeded in expanding the allowable coverage for many drugs and services, resulting in greater access to oncology treatments for the cancer patient.
