What Are Medical Billing Companies in Tennessee?
Medical billing companies in Tennessee manage claims, payments, denials, appeals, patient balances and related revenue cycle work for healthcare practices. Their work has to account for Tennessee payer rules, including the 21-day payment clock on electronic clean claims under Tenn. Code Ann. section 56-7-109 and a TennCare filing window that closes 120 days after the date of service.
Tennessee Practices Are Losing Revenue in Places They Cannot See
Two clocks decide how much a Tennessee practice keeps. Most practices only watch one of them.
The first is TennCare’s. A claim to a TennCare managed care plan has to arrive within 120 calendar days of the date of service. Fee-for-service TennCare allows a year, and so does most of the country. A billing routine built on a 365-day habit bleeds TennCare money every month, and the denials it throws off look like coding problems, so that is how they get worked.
The second clock runs backwards. Tennessee replaced its recoupment statute effective July 1, 2024, and a payer now has 15 months from the day it paid to come back for the money. Six months if it verified eligibility first. Those letters land long after the account was closed and the person who worked it moved on.
Between the two sits the revenue that gets written off by habit: prior authorizations that were deemed approved and never billed that way, credentialing periods nobody claimed retroactive payment for, statutory interest nobody invoiced. That work needs eligibility verification before the visit, certified medical coding on the claim, and someone still watching the account after the money lands.
Medical Billing Services for Tennessee Practices
Full-Service Medical Billing
Our full-service medical billing team manages the revenue cycle from eligibility through payment posting and zero balance. Your dedicated team works inside your existing practice management or EHR system instead of forcing you through a disruptive software migration.
Medical Coding
Our certified medical coders review documentation and apply the appropriate coding workflows for your specialty and payer mix. Better coding upstream can prevent avoidable denials downstream.
Denials and AR Recovery
Old accounts are often the fastest place to find recoverable revenue. Our denials and AR recovery service prioritizes aged accounts, identifies denial patterns, works payer responses, and pursues appropriate appeals and follow-up until the account reaches resolution.
Eligibility and Benefits Verification
Eligibility problems can create avoidable write-offs and patient-balance confusion. We verify coverage and benefits so your team has the information needed before claims and patient statements move forward.
Prior Authorization
Authorization requirements vary by payer, plan, service, and specialty. We manage prior authorization workflows so required approvals are addressed before services become preventable billing problems.
Patient Billing
Patient balances are part of the revenue cycle too. Our patient billing support keeps statements, balances, and follow-up organized so your practice is not leaving the final portion of earned revenue unattended.
Credentialing
Credentialing problems can delay payments before the first claim is ever submitted. We support provider enrollment and credentialing so practices stay operational with the plans they serve.
RCM, CCM and Telehealth
Practices increasingly need billing workflows that account for multiple care models and remote services. We support revenue-cycle processes for RCM, chronic care management, and telehealth programs, with medical virtual assistant support where a practice needs front-office coverage alongside billing.
Dashboards and Automations
You should not need to wait for a monthly spreadsheet to understand what is happening to your revenue. We use reporting and workflow automation to make trends in AR, denials, collections, and billing performance easier to identify and act on.
How Our Medical Billing Process Works
1. Start With a Billing Review
We begin with a 30-minute review of your AR aging, denial patterns, payer mix, and current billing workflow. The goal is simple: identify what is actually costing you money and where we would start.
2. Build the Revenue Recovery Plan
We identify the accounts, payer issues, coding patterns, workflow gaps, and filing risks that deserve attention first. You get a clear view of what should be worked immediately and what needs a process change.
3. Start With the Oldest Money
Working aged AR comes first because it represents revenue you have already earned. Our team works the backlog while establishing a consistent process for new claims and daily billing.
4. Run the Full Cycle
Once the foundation is in place, we take over the agreed portion of the revenue cycle: eligibility, coding, submissions, payment posting, denials, appeals, AR follow-up, patient billing, and reporting.
5. Improve the System, Not Just the Claims
The goal is not to create a permanent cycle of denials and appeals. We look for repeatable patterns so the practice can prevent the same billing problems from occurring again.

Medical Billing in Tennessee: Understanding the Payer Landscape
One carrier sets the tone for commercial billing in Tennessee. BlueCross BlueShield of Tennessee held 71% of the fully insured large group market and 72% of small group in 2024, on KFF’s numbers. Cigna and UnitedHealthcare split most of what is left, and the top three together take 96.6% of large group and 99.4% of small group. In daily terms that means one payer’s edit logic, one payer’s authorization list and one payer’s appeal queue account for most of a Tennessee practice’s commercial denials.
TennCare covered 1,357,979 people in July 2026 and runs on three at-risk managed care organizations, all three statewide: BlueCare, UnitedHealthcare Community Plan and Wellpoint, which carried the Amerigroup name until 2023. TennCare Select, operated by BlueCare Tennessee, handles foster care, SSI children and Katie Beckett enrollees. Dental benefits moved to Renaissance on November 1, 2025, and pharmacy sits with OptumRx. Any practice that verified a dental benefit against the old administrator in October and billed it in November already knows about that one.
Tennessee has not expanded Medicaid. TennCare runs under the TennCare III aggregate cap waiver, approved in January 2021 and running through 2030, which lets the state keep a share of savings when spending stays under the cap. The billing consequence of no expansion is the uninsured rate: 9.65% in 2024, eleventh highest in the country, against 8.2% nationally. Self-pay balances are a bigger line here than in most states, and they are collectible only if someone works them.
Medicare is the other half of the mix. Tennessee had 1,532,665 eligibles in August 2026 and 823,562 of them in Medicare Advantage, a penetration rate of 53.7% against 51.7% nationally. Part A and Part B fee-for-service runs through Palmetto GBA, the A/B MAC for Jurisdiction J, covering Alabama, Georgia and Tennessee. Advantage plans do not. Each carries its own authorization rules, filing window and appeal path, so re-checking plan assignment at eligibility is what keeps a Medicare claim from being worked against the wrong set of rules.
Tennessee Billing Rules That Can Affect Your Revenue
120 days TennCare managed care, 1 year TennCare fee-for-service
Timely filing
21 days electronic, 30 days paper
Prompt-pay requirement
TennCare
State Medicaid program
Commercial claims run on Tenn. Code Ann. section 56-7-109. A health insurance entity has 21 days to pay a clean claim filed electronically and 30 days for a paper claim, and it has to process and pay 95% of clean claims inside those windows. A clean claim is one with no defect, impropriety or missing documentation that prevents timely payment. Late payment carries interest at 1% per month. The Commissioner of Commerce and Insurance can penalize an entity that misses the 95% threshold, up to $10,000.
The rule most worth knowing is newer than that. Tennessee deleted and replaced section 56-7-110 in 2024, effective July 1, and what replaced it is the most provider-friendly recoupment rule of any state we bill in. A payer has 15 months from the date it paid to recoup a claim, 18 months for the state employee plan, and only 6 months if the payer or its verification agent confirmed the patient was covered and your practice relied on that confirmation. Fraud is the only exception.
The notice rules are where most recoupments fall apart. Before recouping, the payer has to give at least 30 days written or electronic notice, and that notice has to carry eight specific things: the CPT codes or a description of the services, a detailed explanation including the codes it believes should have been billed and the policies behind them, the claim numbers, the patient’s full legal name and identification numbers, the dates of service, the estimated amount, the payment date and method for each claim with its check or EFT identifier, and the appeal process. A notice missing any of that is not a compliant notice.
Most practices pay them anyway.
Two more provisions matter and almost nobody uses them. Appeal within 30 days of the notice and the payer cannot withhold payment until every appeal is exhausted. And a recoupment cannot be based on extrapolating from a sample of audited claims. None of this can be waived by contract. Where a payer violates it, the commissioner can impose twice the claim amount or $750, whichever is less, and the practice can go to chancery or circuit court where it practices. Structured AR recovery tests the notice, the payment date and the extrapolation question before any money leaves the account.
Prior authorization changed too. The Prior Authorization Fairness Act took full effect on January 1, 2025, and it gives Tennessee something most states still do not have: a deemed-approved rule. A non-urgent request is deemed approved if the plan does not approve it, deny it, or request all additional information within 7 calendar days. Urgent requests run on 72 hours plus one business day. Once information is requested the plan gets 5 more calendar days, and the whole process is capped at 17 days. An approval has to hold for at least 6 months. A prior plan’s authorization has to be honored for the first 90 days after a patient changes coverage. A plan that approves an authorization has to pay the contracted rate, with four narrow exceptions, and it has to publish its denial statistics including its top five denial reasons. The act does not reach ERISA self-funded plans, TennCare or CoverKids.
Credentialing carries a payment right most groups never claim. Under section 56-7-1001 an insurer has 5 business days to say whether an application is complete and 90 calendar days after that to deliver a decision. Hold the claims while it is pending. When the decision arrives, submit them, and the insurer has to pay the in-network contracted rate for covered services delivered between the date it received the complete application and the date it issued its decision. The right applies to services billed under an existing group contract, and it disappears if the applicant leaves the application incomplete for 30 days. TennCare, CoverKids and the state group plan are excluded.
TennCare keeps its own clocks and they are short. Managed care claims are due within 120 calendar days of the date of service. Fee-for-service TennCare and pharmacy allow a year, school-based IEP services allow a year, and a Medicare crossover claim sent directly to TennCare allows 6 months from the Medicare notice. The plans themselves are held to section 56-32-126: 90% of clean claims processed and paid within 30 calendar days and 99.5% within 60, with the CHOICES and ECF CHOICES long-term care programs on a tighter 14 and 21 day standard.
Two things Tennessee does not have. There is no state surprise billing statute, no state out-of-network payment benchmark and no state arbitration process, so the federal No Surprises Act governs. The Department of Commerce and Insurance told CMS it lacks authority to enforce most of the act, which means CMS enforces those provisions directly here and the federal IDR process sets out-of-network rates. There is also no gold-carding law. The nearest thing to it is the 90-day portability rule above.
Workers’ compensation is a separate system with better margins than most practices assume. Under Bureau of Workers’ Compensation rule 0800-02-17 a payer has to pay a properly submitted, undisputed bill within 30 calendar days, and it has 15 business days to tell you a bill was not properly submitted. Preauthorization for non-emergency surgery, hospitalization and inter-facility transfer is deemed approved if no decision arrives in 7 business days. The fee schedule pays 200% of the Tennessee Medicare rate for evaluation and management, surgery, radiology, pathology and emergency care, 180% for therapy and laboratory work, and 275% for surgical codes billed by a board-certified or board-eligible orthopaedic surgeon or neurosurgeon. Late electronic bills carry penalties from $50 to $5,000.
Tennessee Medical Practices We Serve
Behavioral health is where the Tennessee rules bite hardest. TennCare carries a large share of behavioral health volume across all three plans, so the 120-day filing window covers most of it, and the Prior Authorization Fairness Act does not, because TennCare is carved out of the act. Commercial behavioral health gets the opposite deal. The 7-day deemed-approval rule applies there, and a request that went unanswered is an approval somebody billed as a denial.
Emergency medicine and hospital-based groups carry the out-of-network exposure. With no Tennessee balance billing statute and no state arbitration, every disputed out-of-network claim goes to federal IDR, and those are won on batching, deadlines and a documented record of every offer. Anesthesiology, radiology and pathology groups sit in the same position. Tennessee has 915 anesthesiologists, 989 diagnostic radiologists and 513 pathologists in active practice, and most of them bill through hospital-based arrangements where nobody owns the appeal.
Orthopedics and occupational medicine should be looking hard at their workers’ compensation mix. A board-certified orthopaedic surgeon bills workers’ compensation surgery at 275% of the Tennessee Medicare rate under modifier ON. That is the highest-paying line in most orthopedic practices and it gets underbilled because the modifier is missed.
Rural practices are a fourth group. Tennessee has 333 Rural Health Clinics, 15 Critical Access Hospitals and two Rural Emergency Hospitals, and it has lost 14 rural hospitals since 2012, second only to Texas. The practices still standing absorb that referral volume, and they need provider credentialing current with all three TennCare plans before a claim goes out.
Serving Major Tennessee Markets
- Nashville
- Memphis
- Knoxville
- Chattanooga
- Clarksville
- Murfreesboro
- Franklin
- Johnson City
Nashville and Memphis are two different billing markets that happen to share a state. Nashville carries the commercial and Medicare Advantage weight, along with the corporate health systems headquartered there. Memphis and Shelby County carry the heaviest TennCare concentration in Tennessee, 230,511 enrollees in July 2026, more than Davidson, Knox and Hamilton counties put together. Knoxville and the Tri-Cities sit inside a hospital footprint that crosses into Virginia and North Carolina, so a group up there is often billing three states under one tax identification number. Clarksville’s payer mix carries a military share that Murfreesboro’s does not. A practice with locations in Nashville and Memphis is running two payer mixes on one credentialing calendar. We work remotely inside your existing system, so those markets stay visible separately instead of averaging into a single statewide number.
We run the same model in other states, with the payer rules, filing windows and Medicaid structure rebuilt for each one. See Georgia medical billing, Alabama medical billing, Virginia medical billing, North Carolina medical billing, Florida medical billing, Texas medical billing, Ohio medical billing, Washington medical billing, Iowa medical billing, Rhode Island medical billing, Hawaii medical billing, Alaska medical billing, and Montana medical billing, or start from the full list of medical billing companies.
What Tennessee Practices Say About Working With Luxen
Our procedure, pathology, and professional charges were being handled as separate transactions, so missing components were difficult to spot. Luxen introduced case-level reconciliation, reduced unresolved charge exceptions by 70%, and recovered $56,700 that had never reached the claim stage.
Practice Administrator, Gastroenterology Group, Nashville, Tennessee
Incomplete orders and unsigned plans of care were holding up a significant portion of our billing. Luxen created a documentation-aging workflow that reduced claims waiting on records from $137,000 to $29,000 in four months and gave our clinical team a clear list of what needed attention.
Director of Operations, Home Health Practice, Knoxville, Tennessee
The same approach, documented end to end: our ambulance billing case study and dental practice case study.
What Does Medical Billing Cost in Tennessee?
3% to 6% of collections
Luxen's pricing generally falls between 3% and 6% of collections, depending on claim volume, specialty, payer mix, and how much of the revenue cycle your practice hands over.
Larger-volume practices can generally access the lower end of the range because billing economics improve as claim volume increases. A smaller or more complex practice may fall toward the higher end because the amount of work per account is greater.
For comparison, published billing-industry pricing guides commonly place percentage-based medical billing somewhere around the mid-single digits, with higher ranges for smaller or more complex practices.
The more important question, however, is not whether a billing company charges 3%, 4%, 5%, or 6%.
It is what happens to collections after you hire them.
A lower fee attached to weak billing is still expensive.
The Risks of Outsourcing Your Medical Billing
Outsourcing is not automatically the right choice for every practice.
A billing company is a poor fit if you are unwilling to share operational visibility, if the vendor uses a rotating pool of people who do not learn your practice, or if the company cannot explain why your claims are being denied.
There is also a real risk in choosing a vendor that promises aggressive collection improvements without understanding your payer mix and specialty.
That is why Luxen starts with the numbers.
You should see the AR aging. You should understand your major denial categories. You should know what is being worked. And you should know what your billing company believes is realistically recoverable.
The right outsourcing relationship should make your revenue cycle more visible, not less.
How Much Revenue Are You Missing?
Look at your AR aging.
- How much is sitting past 90 days?
- How much is past 120 days?
- Which payers represent the largest outstanding balances?
- What are your top five denial reasons?
- How many claims are repeatedly resubmitted without a clear resolution?
- How much patient responsibility remains uncollected?
- How many claims are approaching a filing deadline?
Those numbers tell a story.

A Message From the Luxen Founder
I started Luxen because medical practices should not have to choose between doing great clinical work and running a financially healthy business.
Billing is too important to be treated as an afterthought. When claims are submitted incorrectly, denials sit untouched, or aged AR is ignored, the practice feels it everywhere, from cash flow and payroll to staffing decisions and growth.
Our job is to bring discipline to that part of the business.
We work inside the systems practices already use, build accountable billing workflows, and focus on the revenue that is actually recoverable.
We believe your billing partner should know your numbers, your specialty, your payers, and your practice, not just your account number.

Tennessee Medical Billing FAQs
Why outsource medical billing in Tennessee?
Outsourcing puts someone on work that never survives a front desk’s daily list. TennCare managed care claims die at 120 days, a third of the window most states allow. Payers can recoup a paid claim for 15 months and have to meet eight separate notice requirements to do it, and most of those notices are never tested. Prior authorizations left unanswered past 7 days are approvals in law and write-offs in practice.
Do you work with TennCare?
Yes. We work TennCare claims across BlueCare, UnitedHealthcare Community Plan and Wellpoint, plus TennCare Select, to the 120-day filing deadline for managed care and the one-year window for fee-for-service. We track the November 2025 move of dental benefits to Renaissance, and the 6-month deadline for Medicare crossover claims sent directly to TennCare rather than through a plan.
How do you handle denied claims?
We assign every denial, correct what can be corrected, appeal the rest, and follow each account to payment or a documented disposition. Repeat denials get traced back to the cause, whether that is eligibility, coding, authorization, filing or routing. Tennessee adds one hard limit worth using: under section 56-7-110 a payer cannot recoup a claim paid more than 15 months earlier, 6 months if it verified eligibility, and it cannot extrapolate from a sample.
Is this cost-effective for a small Tennessee practice?
Luxen generally charges 3% to 6% of collections. For a small practice the fee is worth measuring against money nobody is currently touching: recoupments taken without a compliant 30-day notice, claims lost to the 120-day TennCare window, authorizations deemed approved and billed as denials, and in-network payment never claimed for a credentialing period under section 56-7-1001. None of that needs new software.
