Medical Billing Services in Tennessee
Tennessee abolished fee-for-service Medicaid in 1994 — TennCare was the first fully managed-care Medicaid program in the country, and thirty years on there is still no FFS lane: every TennCare claim bills to one of three MCOs, with 120 days the commonly published filing window. The commercial market belongs overwhelmingly to BlueCross BlueShield of Tennessee, whose BlueCare product is also the largest TennCare plan — meaning one Chattanooga-based company touches most Tennessee claims one way or another. And Nashville is the healthcare industry's corporate capital (HCA and a dense cluster of health services companies call it home), which shapes an employer market unusually fluent in its own billing.
TennCare: filing rules that decide whether you get paid
Administered by the Division of TennCare
TennCare has no fee-for-service program — every member is enrolled with one of three statewide MCOs: BlueCare (BlueCross BlueShield of Tennessee), UnitedHealthcare Community Plan and Wellpoint (formerly Amerigroup). The commonly published filing window is 120 days from the date of service, but each MCO's provider manual is the controlling document for filing, prior auth and appeals — and they differ in real ways. Providers register with TennCare for a Medicaid ID, then contract separately with each MCO; skipping a plan means losing access to a third of the TennCare population.

Tennessee billing rules that move real money
No FFS lane — MCO manuals control everything
Because TennCare is entirely managed care, there is no state FFS rulebook to fall back on: BlueCare, UHC and Wellpoint manuals are the law of the land for filing windows, auth lists and appeal deadlines. Multi-state billers who work Tennessee claims to generic Medicaid assumptions lose money here — every rule is plan-specific.
Tennessee prompt-pay requirements
Tennessee law holds carriers to statutory claim-processing deadlines with interest on late payment, enforced through the Department of Commerce and Insurance. Combined with BCBST's market share, systematically documenting one dominant payer's turnaround pays off disproportionately in this state.

Credentialing & enrollment in Tennessee
Physician licensing in Tennessee runs through the Tennessee Board of Medical Examiners, and payer enrollment is its own workstream on top of it — state Medicaid enrollment, CAQH upkeep, and individual plan contracting each on their own timeline. Our credentialing service manages the full stack for Tennessee providers, and our credentialing calculator estimates realistic timelines by payer.
Tennessee billing FAQs
What is the timely filing limit for TennCare?
TennCare has no fee-for-service program — the commonly published MCO window is 120 days from the date of service, but each plan's manual (BlueCare, UnitedHealthcare Community Plan, Wellpoint) is controlling. We work each plan to its own deadline.
Do I need to contract with all three TennCare MCOs?
If you want access to the full TennCare population, yes — members are split across BlueCare, UHC and Wellpoint statewide. We handle TennCare registration plus the three separate MCO contracting and credentialing tracks.
Why does BCBST matter so much in Tennessee?
BlueCross BlueShield of Tennessee holds the largest commercial share and runs BlueCare, the biggest TennCare plan — one company's edits, auth lists and portal behavior touch most claims in the state. We know its rulebook cold.
Do you bill Farm Bureau Health Plans?
Yes — Farm Bureau coverage is common in rural Tennessee and doesn't behave like standard commercial insurance. We handle its submission and follow-up rules alongside conventional payers.
