Why California Oncology Practices Need Specialized Billing

California's healthcare market includes 110,000+ physicians, and oncology practices here face a payer market dominated by Blue Shield of California / Anthem on the commercial side and Medi-Cal on the public payer side. Medicare claims are processed through Noridian, which applies its own Local Coverage Determinations that directly affect oncology procedure coverage and medical necessity requirements. Generic billing teams without CA specific knowledge leave revenue on the table.

Oncology billing itself is complex. Oncology billing involves chemotherapy/infusion administration codes (96413-96417), drug product codes (J-codes), radiation therapy coding (77385-77387), and high-complexity E/M for treatment planning. Drug reimbursement (buy and bill) is a significant revenue component. When you combine this coding complexity with California's specific payer rules, authorization requirements, and 5 Medi-Cal managed care plans that each have their own billing rules, you need a team that understands both dimensions. Go Medical Billing provides that expertise at 2.49% of collections, serving oncology practices from Los Angeles to Oakland and across California.
