Tennessee Medical Billing and Payer Rules
Tennessee Medicaid is TennCare, run by the Division of TennCare, and most claims go to a managed care plan rather than to the state. Medicare Part A and B claims go to Palmetto GBA (JJ) with a one-year filing limit. This page separates what is verified from what you must confirm.
In short: most Tennessee Medicaid claims go to TennCare managed care plans, and Medicare claims go to Palmetto GBA (JJ) within one calendar year. Out-of-network disputes run through the federal No Surprises Act unless you confirm a state pathway in writing.

Tennessee and the Federal No Surprises Act
This page cites no Tennessee surprise billing statute for state-regulated plans. The federal Act supplements state laws and applies wherever a state law does not.
Major Payers
How Does TennCare Work for Billing?
Tennessee runs Medicaid as TennCare, administered by the Division of TennCare inside the Tennessee Department of Finance and Administration. The state's own quarterly monitoring report to CMS names the Division of TennCare as the agency behind the TennCare III demonstration (Project No. 11-W-00369) and describes the program as a single, statewide managed care service delivery system.
For a billing team the practical meaning is simple. Most TennCare claims do not go to one state claims system. They go to a managed care organization (MCO), and each MCO has its own portal, provider manual and claim edits. Learn the plan before you learn the program. The general rules are in our Medicaid billing guide.
Which Plans Does TennCare List?
TennCare's managed care organizations page lists the same four health plans in West, Middle and East Tennessee: Wellpoint (formerly Amerigroup), BlueCare, UnitedHealthcare Community Plan and TennCare Select. Each region's list also names the counties it covers. The CMS-hosted TennCare III monitoring report for January to March 2024 shows the same four plan names, plus DentaQuest and Optum columns for the dental and pharmacy contractors.
Plan names and contracts change, so confirm the current list with the Division of TennCare before you load a payer table.
What the Claim Path Looks Like
- Verify eligibility and the member's assigned plan for the date of service. The plan, not the Division, adjudicates the claim.
- Submit the claim to that plan in the format its manual requires. Hospital claims are institutional (UB-04 data sent as an 837I), physician claims are professional (CMS-1500 data sent as an 837P).
- Read the remittance and the denial reasons. Correct and resubmit when the denial is a data problem, and appeal only when the plan decision itself is wrong.
- Start the plan's appeal clock on the day the denial is issued.
What Is the TennCare Timely Filing Limit?
TennCare managed care organization (MCO) claims must be filed within 120 calendar days. TennCare's policy PAY 13-001 (Rev. 2, June 1, 2022) sets that limit for MCOs and for the dental benefits manager, one year for the pharmacy benefits manager, and one year for claims TennCare pays itself on a fee-for-service basis, such as ICF/IID, certain waiver and Department of Children's Services claims, and Medicare crossovers.
Timely filing is normally counted from the date of service. If a member's eligibility was made retroactive, the clock for an MCO starts on the date TennCare notifies the MCO of the enrollment, and for TennCare itself on the date the record is loaded. School-based therapy and audiology claims under an IEP have a one year limit with an MCO. If a Medicare claim did not cross over automatically and is past one year, the provider has six months from the Medicare payment or denial notice to ask TennCare for crossover payment directly. Federal rule 42 CFR 447.45(d)(1) sets the 12 month ceiling under all of this.
| Payer | Limit | Where it comes from |
|---|---|---|
| Medicare Part A and B (Palmetto GBA) | 1 calendar year after the date of service | 42 CFR 424.44(a)(1) |
| Medicaid agency, federal requirement | Providers must submit all claims within 12 months of the date of service | 42 CFR 447.45(d)(1) |
| TennCare MCO claims | 120 calendar days from the date of service, with retroactive eligibility and third party liability exceptions | TennCare policy PAY 13-001, Rev. 2 (June 1, 2022) |
| TennCare fee-for-service (including Medicare crossover) | 1 year | TennCare policy PAY 13-001, Rev. 2 (June 1, 2022) |
| TennCare appeal windows | Not stated on this page. Read the denial notice and the plan manual | Each plan and the Division of TennCare |
How the Medicare Clock Can Move
Under 42 CFR 424.44(b), the one-year limit is extended in four situations: an administrative error by a Medicare contractor or agent, retroactive Medicare entitlement, retroactive entitlement where a state Medicaid agency recovered its payment six months or more after the service, and retroactive disenrollment from a Medicare Advantage plan after the plan recovered its payment. In each case the extension runs through the last day of the sixth calendar month after the triggering event. An administrative error request made more than four years after the date of service is not eligible.
Under 42 CFR 424.44(c), a deadline that falls on a weekend or federal holiday moves to the next workday.
Who Is the Medicare Contractor for Tennessee?
Palmetto GBA, LLC is the Medicare Administrative Contractor (MAC) for Tennessee. CMS states that JJ processes fee-for-service Medicare Part A and Part B claims for Alabama, Georgia and Tennessee. One contractor therefore handles Part A hospital claims and Part B professional claims for the whole state, so your rejection and denial handling stays consistent across both.
| Claim type | Contractor | Jurisdiction on the CMS list |
|---|---|---|
| Part A and Part B | Palmetto GBA, LLC | J (JJ) |
| Home health and hospice (HH+H) | Palmetto GBA, LLC | M |
| Durable medical equipment | CGS Administrators, LLC | DME C |
The home health, hospice and DME rows come from the CMS MACs-by-state list dated March 2023, the newest version we found. Recheck it before you route those claims.
Medicare Timely Filing and Appeals
Medicare fee-for-service claims must be filed within one calendar year of the date of service under 42 CFR 424.44(a)(1). If Palmetto GBA denies a claim and the denial is wrong, the first appeal is a redetermination. Under 42 CFR 405.942, a request must be filed within 120 calendar days from the date the party receives the notice. Receipt is presumed to be 5 calendar days after the date of the notice unless evidence shows otherwise, and the contractor may extend the window if you show good cause.
The next level is reconsideration by a qualified independent contractor. Under 42 CFR 405.962 that request must be filed within 180 calendar days from the date the party receives the redetermination notice, with the same 5-day presumption of receipt.
For payer-level detail on Medicare billing, see Medicare billing rules.
Does Tennessee Have a Prompt Pay Law, and What Does Federal Medicaid Timing Require?
Tennessee regulates how fast commercial insurers must pay in Tenn. Code Ann. 56-7-109. A 2014 Department of Commerce and Insurance bulletin says the section requires clean claims to be paid no later than 30 calendar days after the insurer receives the claim, and defines a clean claim as one with no defect, impropriety or missing required documentation. An earlier Department citation, from 2003, described the section as giving 30 calendar days for paper claims and 21 days for electronic claims, with three allowed responses: pay the claim, pay the undisputed part and explain the rest in writing, or explain in writing why it is not clean. We have not confirmed the current statute text or the late-payment interest rate, so check the code before you cite a figure in a dispute letter.
The Medicaid side has a federal rule we did open. Under 42 CFR 447.45(d), a Medicaid agency must pay 90 percent of clean claims from practitioners within 30 days of receipt and 99 percent within 90 days. A clean claim there is one that can be processed without obtaining additional information from the provider, and the date of receipt is the date the agency receives the claim, as shown by its date stamp.
Managed care is covered by 42 CFR 447.46. A contract with an MCO must provide that the organization will meet the same requirements. The MCO and its providers may, by mutual agreement, set an alternative payment schedule, and any alternative schedule must be stipulated in the contract.
Does Tennessee Have Its Own Surprise Billing Law?
This page cites no Tennessee surprise billing statute for state-regulated plans, and we state none. The CMS Questions and Answers on the No Surprises Act and State Laws, revised August 2023, lays out how the layers fit: the federal No Surprises Act supplements state surprise billing laws and does not replace them. If a state has a law that does not apply to a specific item or service, the federal Act applies to it.
When a state law does apply, the CMS document says the state law generally controls as long as it gives protections equal to or stronger than the federal Act. A "specified state law" is one that provides a method for determining the total amount payable to an out-of-network provider or facility, and where one applies it sets the out-of-network rate and the amount behind patient cost sharing.
- States have primary enforcement authority over insurers, facilities and providers, and CMS enforces any provision a state fails to substantially enforce.
- A state cannot enforce its surprise billing protections against a self-funded plan unless the plan has opted into the state law.
- The No Surprises Help Desk, 1-800-985-3059, can tell a caller whether federal or state law applies and which state agency to contact.
The practical consequence for a Tennessee emergency group or hospital: until you confirm a state pathway in writing from the Tennessee Department of Commerce and Insurance, run out-of-network disputes through the federal route. That means open negotiation and then federal IDR for items and services the Act covers. Our overview of state surprise billing laws explains how to check each state.
Balance Billing for Ground Ambulances
The federal Act covers air ambulance services. This page cites no official source that settles ground ambulance balance billing for Tennessee state-regulated plans, so it states no rule for it. Ask the plan and the Department of Commerce and Insurance in writing before you bill a patient above the plan's allowed amount.
Which Payers Matter in Tennessee?
Name only the payers you can show are in your state. For Tennessee Medicaid the official roster is the TennCare managed care organizations page: Wellpoint, BlueCare, UnitedHealthcare Community Plan and TennCare Select. For Medicare the contractor is Palmetto GBA. For commercial and Medicare Advantage business, this page cites no Tennessee Department of Commerce and Insurance market share report, so this page lists no commercial payers and gives no market share figures.
| Payer type | Who adjudicates | Your first check |
|---|---|---|
| TennCare | The member's MCO | Assigned plan on the date of service |
| Medicare fee-for-service | Palmetto GBA (JJ) | Medicare Part A or Part B, and the one-year filing limit |
| Commercial fully insured | The insurer, regulated by the state | Contract terms, then state law |
| Commercial self-funded | The plan or its administrator, under ERISA | Federal No Surprises Act applies unless the plan opted in to a state law |
Plan type decides which law applies. A fully insured plan is regulated by the state, a self-funded plan is governed by ERISA.
How Do You Appeal a Denial from a TennCare Plan?
Start with the denial notice and the plan's provider manual. TennCare claims are decided by the MCO, so the first appeal normally goes to the plan, using the form and address the plan names. This page does not state the TennCare appeal deadlines, so the steps below are the method, not the dates.
- Pull the remittance and match every denial reason to a CARC and RARC. A denial for missing data is a correction, not an appeal.
- Check the date on the denial notice and the plan's written deadline. Record both in your tracker the same day.
- Assemble the claim, the notice, the medical record pages that answer the denial reason and any authorization number.
- Send the appeal by the route the plan's manual names, and keep proof of the date it reached the plan.
Our denial management team works denials within 48 hours of posting, which leaves most of the appeal window for building the case.
How We Handle Billing in Tennessee
For Tennessee clients we separate the claim paths first: TennCare plans, Palmetto GBA Medicare, and commercial payers. Each path gets its own filing clock, held to the shortest written deadline in the plan manual or contract. Claims go out within 24 hours of charge entry, and denials are worked within 48 hours.
For out-of-network emergency and facility claims we run eligibility checks first, because the plan type decides whether a state process could apply, then open negotiation and federal IDR where the Act covers the service. Hospitals and facilities can see how we run UB-04 claims, and the out-of-network billing and IDR service covers the dispute work end to end.

Common Questions
Straight answers from the team that does the work.
Ask a billing lead directly. A 20-minute call, Monday to Friday, 9am to 5pm Eastern.
01What is the timely filing limit for Tennessee Medicaid claims and how does it differ for managed care plans?
TennCare MCO claims must be filed within 120 calendar days, per TennCare policy PAY 13-001 (Rev. 2, June 1, 2022). Claims TennCare pays directly, including Medicare crossovers, have one year. Retroactive eligibility moves the start date. The federal ceiling is 12 months under 42 CFR 447.45(d)(1), and plan manuals can be stricter.
02Who is the Medicare MAC for Tennessee, and which jurisdiction is it?
Palmetto GBA, LLC. CMS states that JJ processes fee-for-service Medicare Part A and Part B claims for Alabama, Georgia and Tennessee. Home health and hospice claims for Tennessee sit in Jurisdiction M, also Palmetto GBA, and durable medical equipment claims go to CGS Administrators in DME Jurisdiction C, per the CMS list dated March 2023.
03Does Tennessee have its own surprise billing law, or do out-of-network disputes go to federal IDR?
This page cites no Tennessee surprise billing statute for state-regulated plans, so we do not state one. The federal No Surprises Act applies wherever a state law does not, and it applies to self-funded plans unless they opt into a state law. Confirm with the Tennessee Department of Commerce and Insurance before relying on a state process.
04How do I file a billing complaint or ask a question with the Tennessee Department of Commerce and Insurance?
Use the consumer and complaint pages of the Tennessee Department of Commerce and Insurance on tn.gov, which regulates fully insured plans. Self-funded employer plans are governed by ERISA, not the state. For help deciding whether federal or state law applies, CMS lists the No Surprises Help Desk at 1-800-985-3059.
05What is the prompt payment rule for insurers in Tennessee and what interest applies when a claim is paid late?
Tenn. Code Ann. 56-7-109 requires clean claims to be paid no later than 30 calendar days after receipt, per a 2014 Department of Commerce and Insurance bulletin. A 2003 citation described 21 days for electronic claims. We have not confirmed the interest rate or current text. For Medicaid, 42 CFR 447.45(d) requires 90 percent of clean claims paid within 30 days.
06How do I appeal a denied claim with Tennessee Division of TennCare and what are the deadlines?
The member's MCO decides the claim, so the first appeal goes to the plan under its provider manual. This page does not state the TennCare appeal deadlines, so take the date from the denial notice and the plan manual, and record it the day the denial arrives. Medicare is different: redetermination is 120 days under 42 CFR 405.942.
07Which commercial payers and Medicare Advantage plans matter most for a hospital or ER group in Tennessee?
This page cites no Tennessee market share report, so we do not rank commercial payers. TennCare's managed care organizations page lists Wellpoint, BlueCare, UnitedHealthcare Community Plan and TennCare Select. Pull your own remittances for the last 12 months to see which payers carry your volume.
08Can an out-of-network ER physician group in Tennessee balance bill a patient for emergency care?
Under the federal No Surprises Act, nonparticipating emergency providers cannot balance bill patients covered by plans the Act reaches, and the dispute goes to open negotiation and federal IDR. This page cites no separate Tennessee rule, so confirm any state-law exception with the Department of Commerce and Insurance before billing a patient.
09How should a Tennessee hospital bill UB-04 claims to Tennessee Medicaid compared with Medicare under Palmetto GBA?
Both use the UB-04 data set on an 837I for institutional claims. TennCare claims go to the member's MCO under that plan's manual and edits, while Medicare Part A claims go to Palmetto GBA, which has a one-year filing limit under 42 CFR 424.44. Check bill type and revenue code requirements in each manual.
10What steps do I follow to dispute an out-of-network underpayment in Tennessee: open negotiation, state process or federal IDR?
Confirm the plan type first. For self-funded plans and for services a state law does not cover, start the federal open negotiation period, then federal IDR if it fails. This page cites no Tennessee state dispute process. Use the Department of Commerce and Insurance to confirm whether one applies to a fully insured plan.
