Allergy & Immunology Billing Services in Oregon

Oregon's healthcare market includes 14,000+ physicians, and allergy & immunology practices here face a payer market dominated by Regence BlueCross BlueShield of Oregon on the commercial side and Oregon Health Plan (OHP) administered through 15 regional Coordinated Care Organizations (CCOs) on the public payer side. Medicare claims are processed through Noridian Healthcare Solutions (Jurisdiction F), which applies its own Local Coverage Determinations that directly affect allergy & immunology procedure coverage and medical necessity requirements. Generic billing teams without OR 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 Oregon's specific payer rules, authorization requirements, and 14 Oregon Health Plan (OHP) administered through 15 regional Coordinated Care Organizations (CCOs) 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 Portland to Beaverton and across Oregon.

Oregon has about 14,000 physicians and one of the most distinctive Medicaid programs in the country. Oregon Health Plan (OHP) uses a network of 15 regional Coordinated Care Organizations (CCOs) that integrate physical, behavioral, and dental care under one capitation rate for each region. The CCO model started in 2012 under a federal waiver and is now in CCO 2.0 since 2020, with another transition planned for 2026. CCOs receive monthly per-member-per-month capitation payments and earn incentive bonuses for hitting quality metrics. By 2024, no less than 70 percent of each CCO's provider payments had to be in value-based arrangements. Oregon adopted Medicaid expansion in 2014. The commercial market is dominated by Regence BlueCross BlueShield of Oregon (the larger Pacific Northwest BCBS plan), Moda Health (Oregon-based), Providence Health Plan (Providence-owned), and Kaiser Permanente Northwest. Portland is anchored by Providence Health and Services (the multi-state Catholic system headquartered in nearby Renton, WA), Oregon Health and Science University (OHSU, about $5.4B annual revenue), Legacy Health, and Kaiser Permanente Northwest.

Oregon-specific factors that shape allergy & immunology reimbursement: Oregon's Coordinated Care Organization (CCO) model is one of the most studied Medicaid delivery system reforms in the country. The 15 CCOs integrate physical, behavioral, and dental care under one capitation rate per region.; Oregon Health and Science University (OHSU) is the only academic medical center in the state and is unusual in being a state-owned public corporation rather than a private nonprofit or a state agency.; Kaiser Permanente Northwest operates as an integrated payer-provider serving Oregon and Southwest Washington. It is one of Kaiser's smaller regions but holds significant commercial market share in the Portland metro.. Our OR coders build these into every allergy & immunologyclaim — see how this works alongside our Oregon medical billing and allergy & immunology billing teams.
