Allergy & Immunology Billing Services in Colorado

Colorado's healthcare market includes 16,000+ physicians, and allergy & immunology practices here face a payer market dominated by Anthem Blue Cross Blue Shield of Colorado on the commercial side and Health First Colorado (the state's Medicaid program brand) on the public payer side. Medicare claims are processed through Novitas Solutions (Jurisdiction H), which applies its own Local Coverage Determinations that directly affect allergy & immunology procedure coverage and medical necessity requirements. Generic billing teams without CO 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 Colorado's specific payer rules, authorization requirements, and 6 Health First Colorado (the state's Medicaid program brand) 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 Denver to Lakewood and across Colorado.

Colorado has about 16,000 physicians and an unusual Medicaid program structure. Health First Colorado does not use traditional MCOs for most members. Instead it uses Regional Accountable Entities (RAEs), which are regional organizations responsible for coordinating physical and behavioral health care, paying behavioral health providers, and managing care for Medicaid members in their region. The Accountable Care Collaborative (ACC) program is now in Phase III as of July 2025. There are five RAEs covering different regions of the state. The commercial market is dominated by Anthem Blue Cross Blue Shield of Colorado, with strong competition from Kaiser Permanente Colorado (especially along the Front Range) and UnitedHealthcare. Denver is the largest metro and is anchored by UCHealth (University of Colorado Health), HealthONE (HCA subsidiary), and SCL Health (now part of Intermountain Health after the 2022 merger). Colorado adopted Medicaid expansion in 2014. The state has high physician concentration along the Front Range (Denver, Boulder, Fort Collins, Colorado Springs) and much thinner coverage in the western mountain communities and the Eastern Plains.

Colorado-specific factors that shape allergy & immunology reimbursement: Colorado uses Regional Accountable Entities (RAEs) instead of traditional MCOs for most Medicaid members. The Accountable Care Collaborative (ACC) program coordinates physical and behavioral health through RAEs rather than fully capitated managed care plans.; ACC Phase III launched July 2025 with new RAE contracts, updated behavioral health benefits, and changed credentialing requirements.; Kaiser Permanente Colorado is one of Kaiser's largest regions outside California and operates an integrated payer-provider model along the Front Range. It competes with Anthem BCBS for commercial market share..
