Major Missouri hospitals & health systems
Missouri health care spans major systems such as BJC HealthCare (St. Louis), SSM Health (St. Louis), Mercy (St. Louis), Saint Luke's Health System (Kansas City).

The Missouri healthcare landscape
- Missouri's hospital market is anchored by large nonprofit systems including BJC HealthCare and SSM Health in the St. Louis region and Saint Luke's and Children's Mercy in the Kansas City metro.
- MO HealthNet, Missouri's Medicaid program administered by the Department of Social Services, delivers benefits through a mix of managed care plans and a fee-for-service program.
- Academic medical centers such as University of Missouri Health Care in Columbia, Washington University and Saint Louis University in St. Louis, and UMKC in Kansas City support teaching, research, and statewide referral networks.
- Missouri's two major metros sit on state borders, so St. Louis and Kansas City providers frequently bill payers and patients across Illinois and Kansas lines alongside in-state commercial and government plans.

How does Missouri not expanding Medicaid affect our billing?
Missouri has not expanded Medicaid and has one of the highest uninsured rates in the country, so practices see more self-pay and charity-care work — making clean coding and clear patient billing especially important.
Can FYNQ work with our existing EHR or practice-management system?
Yes. We work inside your current system, so your Missouri practice does not have to switch software to start out-of-network (oon) billing.
Is FYNQ HIPAA-aware and U.S.-based?
Yes. FYNQ uses HIPAA-aware workflows and is U.S.-based, with offices in Houston, TX and Little Rock, AR. Our public website never collects patient health information.
Does Missouri's balance-billing law (SB 1264) affect out-of-network billing?
Yes. Missouri's SB 1264 protections, layered with the federal No Surprises Act, make out-of-network billing and patient cost estimates more complex — an area our team handles directly.
Does FYNQ guarantee a specific clean-claim rate or revenue increase?
No. FYNQ never guarantees specific revenue or collection results. We focus on the process — clean claims, worked denials, and clear reporting — designed to improve billing performance over time.
