Ambulatory Surgical Center Billing Services in Maryland

Maryland's healthcare market includes 22,000+ physicians, and ambulatory surgical center practices here face a payer market dominated by CareFirst BlueCross BlueShield on the commercial side and Maryland Medicaid (HealthChoice managed care program) on the public payer side. Medicare claims are processed through Novitas Solutions (Jurisdiction L), which applies its own Local Coverage Determinations that directly affect ambulatory surgical center procedure coverage and medical necessity requirements. Generic billing teams without MD specific knowledge leave revenue on the table.

Ambulatory Surgical Center billing itself is complex. ASCs bill facility fees on UB-04 forms with HCPCS codes while surgeons bill professional fees on CMS-1500. Implant billing, multiple procedure discounting, and ASC-specific fee schedules add complexity. When you combine this coding complexity with Maryland's specific payer rules, authorization requirements, and 9 Maryland Medicaid (HealthChoice managed care program) 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 ambulatory surgical center practices from Baltimore to Frederick and across Maryland.

Maryland has about 22,000 physicians and the most unusual hospital reimbursement structure in the country. Under a federal waiver, the Maryland Health Services Cost Review Commission sets hospital rates that apply equally to all payers including Medicare, Medicaid, commercial insurers, and self-pay patients. This means a Maryland hospital charges the same rate for the same service regardless of payer. The All-Payer Model has been in place in some form since 1977 and was renewed as the Total Cost of Care Model in 2019. The HealthChoice Medicaid managed care program runs through nine MCOs, including unique provider-based plans like Priority Partners (Johns Hopkins HealthCare) and MedStar Family Choice (MedStar Health). The Baltimore-Washington corridor concentrates most of the state's physicians, with Johns Hopkins, MedStar Health, and University of Maryland Medical System as the three anchor academic systems. Maryland's Medicaid program ran a 2024 health equity incentive program that distributed payments based on socioeconomic disadvantage scores across the state.

Hospital rates are set by the Health Services Cost Review Commission and apply equally to Medicare, Medicaid, commercial, and self-pay.

This is more provider-affiliated MCOs than any other state.; The 2024 HealthChoice agreement allocated health equity incentive payments ranging from about $226,000 for Aetna to about $2.2 million for Priority Partners, based on MCO membership in jurisdictions with the highest socioeconomic disadvantage scores..
