Nashville Mental Health Billing Service: 7 Easy Essentials
A Nashville mental health billing service handles insurance claims for therapy and psychiatry practices, from submission to payment posting and denial follow-up. Nashville practices usually bill commercial plans, Medicare and TennCare, Tennessee’s Medicaid program. Each follows different rules. This guide covers that mix and seven essentials to confirm before you hand off billing.
What a Nashville mental health billing service has to sort out first
A Nashville mental health billing service has to match every claim to the right payer type, because commercial, Medicare and TennCare claims follow different rules. The payer decides where the claim goes, how long you have to file and who answers a denial. Sort your caseload into those groups before you compare vendors.
Private payers
BlueCross BlueShield of Tennessee (BCBST) describes itself in its provider site footer as an independent licensee of the Blue Cross Blue Shield Association. That site links to Availity for log-in. Our BCBST billing guide covers plan details.
Never carry a rule from another Blue plan, or from another carrier, over to BCBST. Each plan publishes its own manual, so pull the rules for every plan you bill.
Medicare and Medicaid
Original Medicare claims from Tennessee go to Palmetto GBA, the Medicare Administrative Contractor (MAC) for Jurisdiction J. A Centers for Medicare & Medicaid Services (CMS) page lists Alabama, Georgia and Tennessee in that jurisdiction, and Palmetto GBA’s site shows the same states.
Nashville is in Davidson County, which TennCare places in Middle Tennessee. Its health plans page (last modified October 24, 2025) lists four plans for every region: Wellpoint, BlueCare, UnitedHealthcare Community Plan and TennCare Select. Our Tennessee Medicaid billing guide adds codes and payers.
To bill TennCare, a practice needs a TennCare provider ID. The provider registration page says that ID is needed to contract with a managed care organization (MCO) and for Medicare crossover claims. TennCare moved behavioral health into the same plans as medical care in a 2009 integration, so one plan covers both.
TennCare’s 2026 prompt pay report measures plans on paying 90% of clean claims within 30 days and 99.5% within 60 days. Your filing deadline comes from each plan’s provider manual and your contract, so read both.
State rules
The Tennessee Department of Commerce and Insurance (TDCI) issued a bulletin saying Tennessee law, Tenn. Code Ann. 56-7-109, requires insurers to pay clean claims within 30 calendar days of receipt. Read the statute for electronic-claim timing, and check your contract.
For telehealth, Public Chapter 990 (2016) amended Tenn. Code Ann. 56-7-1002 so insurers cover telehealth at the same level as in-person care, from January 1, 2017. TennCare’s audio-only program description (August 2021) cites a 2021 change allowing audio-only behavioral health care when other methods are unavailable.

Seven essentials for a Nashville mental health billing service
Use the same seven questions with every Nashville mental health billing service you compare. Write the answers down.
| Essential | What to confirm |
|---|---|
| 1. Payer type | Fully insured, self-funded, Medicare or TennCare, for each client |
| 2. TennCare plan | Wellpoint, BlueCare, UnitedHealthcare Community Plan or TennCare Select on the date of service, through insurance verification |
| 3. Enrollment | A TennCare provider ID, plus payer credentialing for each commercial plan |
| 4. Filing clock | The deadline in each plan’s manual and your contract, written next to the payer name |
| 5. Telehealth | Video or audio-only, with the audio-only conditions documented |
| 6. Out of network | Whether the service bills out-of-network claims |
| 7. Reports | A monthly view of paid, denied and open claims |
On essential 5, TennCare’s audio-only description asks providers to confirm the client’s identity, document the format and medical necessity, and plan for emergencies.
How do I choose a Nashville mental health billing service?
Pick a Nashville mental health billing service that can name your payer types, show how it tracks each filing deadline and send a written report monthly. Ask for a sample report and the HIPAA business associate agreement before any client record moves. Get fee terms in writing, and confirm in writing that the service bills in Tennessee.
What to do Monday morning
- Export your client list with each payer and plan type.
- Mark every TennCare client and note the plan name on the card.
- Write each payer’s filing window next to its name.
- Read an electronic remittance advice from your largest payer to see what it denied.
- Record your clean claim rate, so you can judge any change.
