Medical Billing Services in Tennessee.
Tennessee’s healthcare market is defined by a contrast between its two largest institutions: Vanderbilt University Medical Center — the top-revenue hospital in the state with $5.4 billion in net patient revenue — and HCA Healthcare, the for-profit giant headquartered in Nashville that operates 17 hospitals in Tennessee alone. Between TennCare’s three-MCO managed care structure, the Tennessee Hospital Assessment Act that shapes Medicaid reimbursement, and BlueCross BlueShield of Tennessee’s dominant commercial position, billing in Tennessee rewards payer-specific expertise. Happy Billing delivers it.
Why Tennessee Practices Choose Happy Billing
TennCare — Three-MCO Medicaid Structure
TennCare is Tennessee’s managed care implementation of Medicaid, established in 1994 as one of the first comprehensive state Medicaid managed care programs in the country. As of mid-2024, TennCare covers approximately 1.44 million individuals — roughly 20% of Tennessee’s population. All TennCare members are enrolled in one of three managed care organizations: BlueCross BlueShield of Tennessee (TennCare), Amerigroup Tennessee (now part of Elevance Health), and UnitedHealthcare Community Plan of Tennessee. Each MCO administers a full HMO with its own provider network, prior authorization requirements, and claim submission portals.
Happy Billing manages credentialing and billing workflows with all three TennCare MCOs. TennCare inpatient reimbursement is primarily based on the MS-DRG system; outpatient payments use APC-based methodologies or payer-developed fee schedules. We track each MCO’s authorization requirements, manage timely filing compliance, and handle TennCare Provider Administered Drug (PAD) and FQHC Prospective Payment System (PPS) billing for practices operating under those programs.
Tennessee Hospital Assessment Act and DSH Payments
Under the Tennessee Hospital Assessment Act, hospitals pay an assessment fee that funds increased Medicaid reimbursement. VUMC and other major hospital systems receive payments tied to their proportional share of unreimbursed TennCare costs, creating a complex supplemental payment dynamic. Additionally, Tennessee’s Disproportionate Hospital Share (DSH) program provides supplemental payments to hospitals serving high volumes of uncompensated care. While these programs primarily affect hospital billing, physician group practices billing under employed or contracted arrangements with TennCare hospitals need to understand how global billing arrangements and split-billing arrangements interact with these supplemental payment mechanisms.
TennCare CHOICES — Long-Term Care
TennCare CHOICES in Long-Term Care is Tennessee’s 1915(c) home and community-based services waiver program, organized into CHOICES Group 1 (nursing facility residents) and CHOICES Group 2 (community-based long-term care). CHOICES is administered by the same three TennCare MCOs but with distinct authorization processes and benefit packages from the standard TennCare managed care program. Providers offering personal care, attendant care, or home health services to CHOICES members must follow MCO-specific service authorization requirements and outcome documentation standards. Happy Billing manages CHOICES billing as a specialized service line.
Major Payers and Health Systems
Vanderbilt University Medical Center (VUMC) is Tennessee’s largest and most complex health system — the state’s highest-revenue hospital ($5.4 billion NPR) and one of the top 10 transplant programs in the country. VUMC operates 1,175-bed Vanderbilt University Hospital, Monroe Carell Jr. Children’s Hospital, and Vanderbilt Psychiatric Hospital on its Nashville campus. VUMC has a significant ACO presence and contracts with all three TennCare MCOs. In late 2024, VUMC’s network dropped BlueCross BlueShield of Tennessee’s Medicare Advantage Blue Advantage plans effective January 1, 2025 — a market development that reshuffled Medicare Advantage enrollment across Middle Tennessee.
HCA Healthcare, headquartered in Nashville, operates 17 hospitals in Tennessee under the TriStar Health brand, including TriStar Centennial Medical Center (741 beds) and numerous community hospitals. HCA is the nation’s largest for-profit health system ($70.6 billion 2024 revenue) and the largest graduate medical education sponsor in the US. Ascension Saint Thomas operates multiple Nashville-area hospitals and is part of Ascension Health (the largest Catholic health system). West Tennessee Healthcare anchors the Jackson market (Jackson-Madison County General Hospital, 642 beds). The dominant commercial insurer in Tennessee is BlueCross BlueShield of Tennessee (BCBST), which operates Networks P and S for commercial PPO, individual exchange plans, and the TennCare managed care contracts. Happy Billing maintains active credentialing and billing workflows across all major Tennessee payers and systems.

Tennessee Medical Billing FAQs
How does billing differ across TennCare's three MCOs?
While all three TennCare MCOs — BlueCross BlueShield of Tennessee, Amerigroup/Elevance, and UnitedHealthcare Community Plan — cover the same TennCare benefit package, each has its own provider portal, prior authorization requirements, timely filing windows (typically 90-180 days), and claim adjudication rules. BCBST TennCare uses its own authorization platform; Amerigroup and UHC use the Availity and Optum portals respectively. Happy Billing maintains active workflows with all three MCOs and monitors policy updates published through each plan’s provider bulletin system.
