Gastroenterology Billing Services in Maryland
Maryland's gastroenterology practices face unique billing challenges shaped by CareFirst BlueCross BlueShield's commercial rules, Maryland Medicaid (HealthChoice managed care program) requirements, and Novitas Solutions (Jurisdiction L) Medicare policies. Our AAPC-certified coders specialize in both MD payer rules and gastroenterology coding complexity.
Why Maryland Gastroenterology Practices Need Specialized Billing
Maryland's healthcare market includes 22,000+ physicians, and gastroenterology 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 gastroenterology procedure coverage and medical necessity requirements. Generic billing teams without MD specific knowledge leave revenue on the table.
Gastroenterology billing itself is complex. GI billing centers on endoscopy coding. When a screening colonoscopy (45378) finds a polyp, it becomes a diagnostic procedure with different coding and cost-sharing rules. Getting this conversion right affects both provider reimbursement and patient billing. 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 gastroenterology practices from Baltimore to Frederick and across Maryland.
2026 Maryland Medicare Allowables for Gastroenterology CPT Codes
These are the 2026 Medicare allowable amounts for gastroenterology CPT codes in Maryland, processed under Novitas Solutions (Jurisdiction L). Allowables are locality-adjusted, so MDrates differ from other states — the highest-value gastroenterology code below pays $834.35 non-facility here. Compare any code across states with our Medicare fee calculator by state.

Commercial CareFirst BlueCross BlueShield rates typically run above these benchmarks; Maryland Medicaid (HealthChoice managed care program) rates run below. Figures for reference, not a guarantee of payment.
The Maryland Market Context for Gastroenterology Practices
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.
Maryland-specific factors that shape gastroenterology reimbursement: Maryland is the only state with an All-Payer Model under federal waiver. Hospital rates are set by the Health Services Cost Review Commission and apply equally to Medicare, Medicaid, commercial, and self-pay. The model has been in place since 1977 and was renewed as the Total Cost of Care Model in 2019.; Maryland's HealthChoice program runs through nine MCOs, including provider-owned plans like Priority Partners (Johns Hopkins HealthCare) and MedStar Family Choice (MedStar Health). 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.. Our MD coders build these into every gastroenterologyclaim — see how this works alongside our Maryland medical billing and gastroenterology billing teams.
