Allergy & Immunology Billing Services in California

California's healthcare market includes 110,000+ physicians, and allergy & immunology 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 allergy & immunology procedure coverage and medical necessity requirements. Generic billing teams without CA specific knowledge leave revenue on the table.

Allergy & Immunology billing itself is complex. Allergy and immunology billing revolves around allergy testing codes (95004 percutaneous, 95024 intracutaneous, 95044 patch testing), immunotherapy administration (95115-95117 for injections, 95120-95134 for professional services with provision of antigen), biologic medication J-codes for severe allergic conditions, and pulmonary function testing (94010-94070). Test count accuracy is critical — each allergy test is billed per individual allergen, and a typical testing session involves 40-80 individual tests. 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 allergy & immunology practices from Los Angeles to Oakland and across California.
