Medical Billing Services by State

Medical billing is federal on paper and state-by-state in practice. Every state runs its own Medicaid program with its own filing window — from New Mexico's 90 days to Ohio's full year — its own prompt-pay statute, its own Blue Cross plan, and its own enrollment portal. Our guides cover all 50 states with the rules that actually decide whether your claims get paid, verified against state Medicaid agencies and insurance statutes. We bill for practices nationwide from our Philadelphia base.

Why state rules change your revenue

Three things vary state to state and each one costs real money when missed. Medicaid filing windows range from 90 days (New York, New Mexico, MassHealth) to 12 months (Ohio, Michigan, Florida) — a biller working multi-state claims to a single internal deadline is either leaving margin on the table or losing claims outright. Prompt-pay statutes give providers enforceable payment deadlines with interest — 18% annually in Texas and North Carolina — that most practices never invoice. And payer landscapes are genuinely local: the "Blue Cross" on the card is a different company with different rules in Philadelphia, Chicago and Detroit, and some states run structures that exist nowhere else — Oregon's Prioritized List, Maryland's all-payer model, Arkansas's private option, Connecticut's no-MCO Medicaid.

Our team bills to each state's actual rulebook — verified against the state Medicaid agency and insurance statutes, not a generic national cheat sheet. Read our complete 2026 state regulations guide, start with our timely filing tool or get a free billing audit benchmarked to your state.
