Serving Practices Across Middle, East, and West Tennessee
A2Z provides medical billing services in Tennessee for practices working through one of the country’s most concentrated Medicaid markets. TennCare runs entirely through three managed care organizations, with no fee-for-service fallback if a contract lapses. BlueCross BlueShield of Tennessee shapes network access for nearly every commercial claim in the state. A clean electronic claim has 21 days to get paid before interest starts accruing. We bill for practices in Nashville, Memphis, Knoxville, Chattanooga, and everywhere between them.
A Tennessee practice manager evaluating medical billing companies in Tennessee should know what makes this market different before comparing pricing. Medical billing services Tennessee practices actually need look different from a generic national package.
TennCare has run entirely through managed care since 1994, with the Division of TennCare contracting three MCOs to cover the state’s Medicaid population: BlueCare Tennessee, UnitedHealthcare Community Plan, and Wellpoint Tennessee. There’s no statewide fee-for-service program sitting behind them. A practice without an active contract with a given MCO simply can’t bill that MCO’s members, full stop.
BlueCross BlueShield of Tennessee carries outsized weight here too. Between its commercial line and its BlueCare Tennessee Medicaid affiliate, BCBST touches a larger share of Tennessee claims than any single payer touches in most other states. Cigna and UnitedHealthcare round out the commercial market, but a Tennessee medical billing company that doesn’t know BCBST’s specific network and authorization rules is working at a real disadvantage.
Tennessee also hasn’t adopted Medicaid expansion, which pushes more of the financial risk onto patient balances and high-deductible plans than in expansion states. That reality shapes collections strategy as much as it shapes coding.
Medicare adds one more layer worth knowing. Palmetto GBA processes Part A and B claims statewide under Jurisdiction J. A Memphis-area group with a Mississippi or Arkansas location deals with a second contractor entirely, Novitas Solutions, under Jurisdiction H, since the two states sit in different MAC territories despite being minutes apart.
Since TennCare has no fee-for-service fallback, a lapsed or missing contract with any one of the three MCOs means every claim for that MCO's members gets rejected outright. It's never just underpaid; it's rejected. Checking which MCO a patient belongs to before the visit is the single highest-value habit a front desk can build here.
Each MCO sets its own filing deadline, and they run tighter than most commercial timelines. A claim held even briefly for coding review can miss the window entirely.
A provider credentialed with BCBST commercial isn't automatically in network for BlueCare Tennessee, its Medicaid product. These are separate participation agreements, and assuming one covers the other produces denials that look like credentialing errors because they are.
With no Medicaid expansion, more patients land on high-deductible plans or no coverage at all, which means a larger share of practice revenue depends on collecting directly from patients rather than a payer.
Long-term services and supports under CHOICES, and the employment-focused ECF CHOICES track, both require authorization through the member's MCO before services start. Skipping that step is a common, avoidable denial.
TennCare billing starts with TennCare provider registration, a separate step from contracting with any individual MCO, and skipping straight to MCO paperwork is the most common setup mistake we see.
Once registered, a practice contracts separately with each MCO it wants to bill: BlueCare Tennessee (operated by Volunteer State Health Plan, a BCBST affiliate), UnitedHealthcare Community Plan of Tennessee, and Wellpoint Tennessee, the plan most people still call by its former name, Amerigroup. Each MCO runs its own fee schedule, its own claims address, and its own authorization rules. BlueCare Tennessee billing and UnitedHealthcare Community Plan billing are two genuinely different processes, never two doors into the same room.
Administered by Volunteer State Health Plan under a separate, non-risk agreement, covering defined special populations rather than the general TennCare pool.
Long-term services and supports, and the employment-focused Employment and Community First CHOICES track for people with intellectual and developmental disabilities. Both run through the member's MCO.
A TennCare pathway for children with disabilities or complex medical needs whose family income would otherwise disqualify them.
Tennessee's CHIP program, run alongside TennCare with its own eligibility rules.
Pharmacy runs separately from everything above. OptumRx has been TennCare’s single statewide pharmacy benefit manager since January 1, 2020, regardless of which of the three MCOs a member is enrolled with. And for members eligible for both Medicare and TennCare, each MCO carries its own aligned dual-eligible plan: BlueCare Plus under BCBST, UnitedHealthcare Dual Complete, and Wellpoint’s own dual product, so coordinating Medicare and TennCare benefits stays inside the same MCO relationship a practice already has.
See our home health billing and nursing home billing pages for how CHOICES affects those specialties, our ABA billing and mental health billing pages for behavioral health authorization through the MCOs, and our pediatric billing page for how CoverKids and Katie Beckett fit into a pediatric practice.
Tennessee’s prompt pay law sets a real clock on commercial claims, and workers’ compensation runs on an entirely separate track.
Under Tenn. Code Ann. § 56-7-109, a health insurance entity has 21 calendar days from an electronic claim, or 30 days from a paper claim, to pay a clean claim, pay the undisputed portion, or tell the provider in writing exactly what’s missing. Interest of 1 percent per month starts accruing the day after payment was due. A paper claim can’t be denied on resubmission for documentation the provider already sent once. The gap between 21 and 30 days is a real financial argument for submitting electronically rather than by paper. It isn’t just a convenience. This Tennessee prompt pay law applies to commercial claims specifically, separate from Medicare, TennCare, and workers’ compensation.
The Tennessee Department of Commerce and Insurance enforces this. If an insurer fails to properly process at least 60 percent of its clean claims in a calendar year, the Commissioner can levy a penalty between $100,000 and $200,000, a real number worth knowing when a pattern of late payment looks intentional rather than occasional.
Tennessee workers’ compensation medical billing runs under the Bureau of Workers’ Compensation’s own medical fee schedule and treatment guidelines, separate from the commercial prompt pay statute above. See our orthopedic billing, physical therapy billing, chiropractic billing, and pain management billing pages for how that fee schedule plays out by specialty.

Non-expansion status makes self-pay and high-deductible balances a bigger share of Tennessee practice revenue than in most states, which makes collecting them well a real financial lever rather than an afterthought.
Confirming coverage, or the lack of it, before the appointment sets the right collection conversation from the start.
A patient who knows the number in advance pays a higher percentage of it than one who's surprised at checkout.
Required under the No Surprises Act for uninsured and self-pay patients, and a compliance obligation as much as a courtesy.
A statement that's easy to read and arrives promptly gets paid faster than one that shows up confusing and late.
Confirmed against the right TennCare MCO, commercial plan, or workers' compensation carrier before the visit.
ICD-10-CM, CPT, and HCPCS coding done right the first time. See our medical coding services Tennessee practices rely on.
Built to land inside the 21-day electronic window rather than the slower 30-day paper one.
Denials traced to the actual cause, whether that's a BCBST network mismatch or a missed TennCare filing deadline.
Every payment reconciled, with self-pay balances worked on their own track.
TennCare registration, individual MCO contracts, CAQH attestation, and Board of Medical Examiners license checks, as the separate steps they actually are.
Apple Health is Washington’s name for Medicaid and CHIP, and the Health Care Authority runs the whole program. ProviderOne enrollment comes first, before any managed care contract means anything.
Once enrolled, physical and behavioral health for most members flow through Integrated Managed Care, meaning one plan covers both instead of splitting them the way many other states still do. Washington completed this integration statewide in January 2020. Five MCOs currently participate: Community Health Plan of Washington, Coordinated Care of Washington, Molina Healthcare of Washington, UnitedHealthcare Community Plan, and Wellpoint Washington, the plan most people still know by its former name, Amerigroup. Which plans are actually available depends on the member’s county.
Not everything routes through the MCO, though. Dental care, long-term services and supports, developmental disabilities services, maternity support services, and inpatient psychiatric care all bill straight to ProviderOne, regardless of which managed care plan the member is enrolled in. Treat these as MCO claims, and they’ll come back denied.
Two more pieces sit alongside the main structure. Behavioral Health Administrative Services Organizations handle crisis services and behavioral health outside standard Medicaid coverage, region by region. Behavioral Health Services Only enrollment covers members, including many dual eligibles, who need behavioral health coverage without full medical benefits. And for members eligible for both Medicare and Medicaid, Apple Health Medicare Connect coordinates the two rather than leaving a provider to bill each program separately.

Three separate processes, handled as three. We don't fold them into one generic "credentialing" task.
Tennessee’s own Grand Divisions, East, Middle, and West, aren’t just geography; they’re three different practice environments.
Middle Tennessee centers on Nashville and carries the state’s most competitive billing vendor market, alongside HCA TriStar, Vanderbilt University Medical Center, and Ascension Saint Thomas. Medical billing services Nashville practices search for most often need to account for exactly that competitive payer environment.
East Tennessee runs on Knoxville and Chattanooga, home to Covenant Health, the University of Tennessee Medical Center, and BCBST’s own headquarters. Medical billing services Knoxville and medical billing services Chattanooga both run against this same East Tennessee payer mix.
West Tennessee centers on Memphis, with cross-border patient flow into Mississippi and Arkansas that touches a different Medicare contractor entirely. Practices searching for medical billing services Memphis providers trust should factor that cross-border reality into their billing setup from day one.
