Medical Billing Services in Mississippi
Mississippi carries the nation's heaviest chronic-disease burden into a payer market with narrow coverage: a non-expansion state where MississippiCAN MCOs — Magnolia Health (Centene), Molina and TrueCare (the provider-sponsored newcomer) — carry most Medicaid members, while low-income adults outside the categories remain uninsured. The commonly published state window is 365 days, plan manuals set working deadlines, and BCBS of Mississippi leads a commercial market shaped by the state's rural economics. UMMC in Jackson is the state's only academic medical center — the referral spine for everything.
Mississippi Medicaid / MississippiCAN: filing rules that decide whether you get paid
Administered by the Mississippi Division of Medicaid (DOM)
Mississippi Medicaid's commonly published window is 365 days from the date of service, with most members in MississippiCAN managed care — Magnolia Health, Molina Healthcare of Mississippi and TrueCare, the provider-sponsored plan backed by the state's hospitals — whose manuals set working filing limits and auth rules; CHIP runs through the same carriers. As a non-expansion state, adult eligibility is among the narrowest in the country, so eligibility category screening and retroactive coverage checks on qualifying events are core Mississippi revenue work, not edge cases.
Deadlines for every major payer — including Mississippi Medicaid — live in our timely filing limits tool, with an interactive deadline checker.

Mississippi billing rules that move real money
TrueCare and provider-sponsored billing
Mississippi's newest MCO is owned by the state's hospital community — a provider-sponsored counterweight to the national carriers. Its manuals and edit behavior are still maturing, which cuts both ways: more provider-friendly instincts, less settled precedent. We track its bulletins as a developing rulebook.
Non-expansion economics
Mississippi's coverage gap is among the nation's largest relative to need — low-income adults outside pregnancy, disability and caretaker categories have no Medicaid pathway. Practices manage the gap with retroactive eligibility screening, disciplined self-pay workflows and hospital presumptive-eligibility coordination.
