TennCare Provider Registration and Credentialing: The Medicaid ID, CAQH, the Three MCOs and Palmetto GBA Medicare

A Tennessee practice that wants to be paid for Medicaid patients needs every row below. Each is a separate filing with its own clock, and the timing column repeats only what the agency, the contract or the plan has put in writing.

Physicians are licensed by the Tennessee Board of Medical Examiners, which also ratifies physician assistant and other certificates; renewal notices go out 60 days before expiration and licenses renew online in that window (Board of Medical Examiners). The Department of Health's public license verification site is what TennCare and the plans check against, so confirm your status there before you file.

TennCare's Provider Enrollment home page lists four things a valid TennCare/Medicaid ID number is required for: getting prescriptions covered by the TennCare pharmacy benefit, submitting Medicare/Medicaid crossover claims for members with Medicare primary, contracting with a TennCare managed care organization, and verifying member eligibility. Notice what is missing from that list: fee-for-service billing. TennCare's own policy PRO 11-001 says the program's fee-for-service providers are essentially private ICFs/IID and Medicare crossover providers; everyone else is paid by a plan.

Federal law also puts clinicians who never bill TennCare on the hook. PRO 19-001 requires electronic enrollment for "providers who order, refer, or prescribe services for TennCare members," citing section 5005(b) of the 21st Century Cures Act, and the FAQ adds that a prescriber needs an active Medicaid ID for TennCare to pay for a covered prescription under 42 CFR 455.410. A hospitalist, a radiologist reading for a group, or a physician who only writes orders for TennCare children still needs the ID.

TennCare's How to apply page describes individual registration as a two-step process, and the state has outsourced most of the data entry to CAQH:

1. Complete the TennCare registration request on the Individual Provider Registration Portal. The portal home page says every individual, new or existing, "must have a CAQH ID in order for TennCare to enroll and/or update your information." If you have no CAQH ID, TennCare submits your registration to CAQH, which assigns one and sends instructions to the credentialing address you entered; the portal says to email TennCare if the ID has not arrived within one week. If you already have a CAQH ID, TennCare recommends that your profile list every service location before you register.
2. Complete the Data Spring application. Data Spring is the platform formerly called CAQH ProView, and the road map says providers "must grant Global Authorization or authorize TennCare access to their data." The portal adds that the CAQH ID "must be in an attested status" before TennCare can receive the information.

Once both steps are done and the individual is linked to a group or organization, the Medicaid ID is emailed to the primary address on file as a welcome letter. From then on TennCare pulls the profile automatically every time it is updated, which is why the Current Providers page says licenses, practice locations and credentialing changes for individuals are made in CAQH ProView, not in the TennCare portal. Individual providers, the FAQ notes, "only need to visit the TennCare Provider Registration website once." Our CAQH explained page covers attestation and authorization in detail.

A group practice, clinic or facility does not use CAQH for its own enrollment. The Groups & Entities Road Map lays out six steps: create an account in the TennCare Provider Enrollment Portal and activate it from the emailed link; enter and upload any license or certification issued to the provider type; complete the ownership section; wait for the enrollment team's review, which notifies you by email of status and errors; receive the welcome letter with the group's Medicaid ID and effective date; then contract with the MCOs. The road map carries a warning worth reading twice: if TennCare notifies you of errors and "does not receive an updated application, you will not receive a Medicaid ID."

The group account is also where you add individual providers to the roster, change addresses and update the Disclosure of Ownership declaration (Provider Enrollment FAQs). Which NPI belongs on which application is covered on our NPI Type 1 vs Type 2 page; TennCare's revalidation page adds that providers must obtain and use a unique NPI for each service location and provider type enrolled.

TennCare says the ownership section "must be completed to prevent enrollment delays," and gives one instruction that catches practices already enrolled in Medicare: if the entity is in PECOS, the ownership information "must MATCH or be updated prior to submitting the TennCare enrollment for approval" (How to Complete the Ownership section). A for-profit entity must list its managing employee, anyone with a control interest such as directors, and owners with the percentage held; a non-profit lists managing employees and control interest. The How to Revalidate guide restates it as a CMS requirement for "3 lines of ownership" on a for-profit enrollment, with ownership percentages that are not 0%.

Every entity answers 11 disclosure questions, and a "yes" opens follow-up questions. An incorrect ownership section is returned and delays the Medicaid ID. After enrollment, any change of ownership or change of ownership interest must be reported within 35 days, using the CHOW or CHOI road maps TennCare publishes. The ClaimCarePro intake list for a Tennessee file is on what we need from you to start credentialing.

Federal rules require every state Medicaid agency to screen providers at a limited, moderate or high risk level (42 CFR 455.450). TennCare's PRO 16-001 (Rev. 4, September 3, 2026) publishes the state's table. Physicians, nonphysician practitioners, medical groups and clinics are limited risk: license verification, eligibility verification, ownership review and database checks. Physical therapists "enrolling as individuals or as group practices" are moderate risk and get a site visit, as do independent labs, IDTFs, CMHCs and ambulance suppliers. Newly enrolling home health agencies, DMEPOS suppliers, hospices and skilled nursing facilities are high risk, with fingerprint-based criminal background checks for any owner with 5% or more interest. Screening runs at enrollment, at revalidation and through ongoing monitoring.

The application fee in 42 CFR 455.460 almost never reaches a Tennessee practice. PRO 11-001 (Rev. 16, February 9, 2026) explains that individual physicians and nonphysician practitioners are exempt by federal rule, that managed care providers are exempt under the preamble to the 2011 final rule, and that "the only provider type that is subject to the application fee is private ICFs/IID not enrolled in another state's Medicaid or CHIP program." For them the fee is $730 in calendar year 2025 and $750 in 2026.

TennCare does not publish a processing standard for a new enrollment. PRO 19-001 says only that TennCare "strives to process complete ('clean') provider enrollment applications within established service standards," and that time varies with completeness, accuracy, response to requests and screening. Two numbers do exist. The individual road map says to contact Provider.Registration@tn.gov "if you do not receive communication from TennCare within 10 business days." And the revalidation FAQ says complete revalidation reviews "generally ... take no longer than 30 days," longer when information is incomplete or screening is required.

Status. Groups and entities check status by logging in with the credentials issued during enrollment; individuals watch for the welcome email. TennCare Provider Services is 1-800-852-2683, option 5 for registration questions (the revalidation page says option 4), and Provider.Registration@tn.gov answers by email. If registration assigns you a new Medicaid ID when you already had one, the FAQ asks you to report it so the old number can be restored. Effective dates are set by TennCare, and PRO 19-001 says retroactive enrollment "may be approved when permitted under applicable policy and program requirements," without stating a window. National guidance on status checks is on our Medicaid provider enrollment hub.

TennCare providers revalidate at least every three years on a rolling schedule counted from the approval date of the enrollment, and providers with several locations approved at different times revalidate each location separately. The notice goes by email about 45 days before the deadline to the primary and primary-correspondence addresses on the enrollment, with a phone call as a last attempt. From the date on the notice you have 45 days; after that a termination notice is generated and the Medicaid ID is terminated, which "may also cause your MCO contract to be terminated" (TennCare Revalidation). Reactivation is requested by email, and claims may go unpaid while the ID is lapsed.

Two Tennessee details change how practices should plan. First, the Current Providers page says any update submitted through the portal "will push out the revalidation due date": a license renewal filed on June 1, 2022 against a June 1, 2023 due date produced a new due date of June 1, 2025. Second, CMS has ordered an off-cycle revalidation. TennCare must revalidate all high-risk providers by February 15, 2027, other targeted providers including those without an NPI by June 30, 2027, and all other providers by June 5, 2028, so a practice whose three-year date is far off may still be selected. Individual revalidations run through CAQH ProView; group revalidations follow the nine steps in the How to Revalidate guide, the last of which, clicking "Submit to TennCare," is the one the guide calls "the most important step."

The consequences page spells out what a lapse costs: every MCO and CoverKids contract ends, crossover claims stop, no single case agreements or out-of-network payment even with an authorization number, no eligibility-portal access, and orders, tests and prescriptions written by the individual are not paid. Recredentialing with the plans is a separate 36-month cycle, covered on our recredentialing page.

TennCare's Managed Care Contractors page says medical, behavioral and long-term care services are covered by at-risk MCOs in each region, and "each participating MCO creates their own contracts with providers, maintains their own fee schedules, processes their own claims." The same three plans serve West, Middle and East Tennessee, and all three hold NCQA accreditation. TennCare Select is a fourth product, administered by BlueCare, for populations the state assigns rather than lets choose.

Members switch plans only in a regional change month: March in West Tennessee, May in Middle Tennessee and July in East Tennessee, effective the first of the following month (Provider Enrollment FAQs). A practice in Memphis that joins only one plan therefore locks out two-thirds of its potential TennCare patients for most of the year. Dental is carved out: since November 1, 2025 Renaissance is TennCare's Dental Benefits Manager, reached at 866-864-2526, and a dentist still needs the Medicaid ID first (Dental Providers).

Tennessee is unusual in writing the plans' credentialing deadlines into the state contract rather than leaving them to each insurer. Section A.2.11.10 of the Statewide MCO Contract with Amendment 25 (July 1, 2026) requires each MCO to use NCQA standards and to "completely process and either approve or deny new credentialing applications and recredentialing applications from all types of providers ... within thirty (30) calendar days of receipt of a complete credentialing application." The rest of the section:

• A complete application is defined by Tenn. Code Ann. § 56-7-1001(a)(2) "in addition to having an active Medicaid identification number." No TennCare ID, no complete application, no clock.
• An incomplete application draws written notice within 5 business days listing what is outstanding. If the provider does not complete it within 30 calendar days of that notice, the plan must discontinue credentialing, tell the provider within 5 business days, and the provider starts over.
• Once the provider agreement is signed, the plan has 30 calendar days to load the provider into its enrollment file and claims system.
• Recredentialing may run up to 36 months, in line with NCQA.
• Files that fail initial criteria and need heightened Credentialing Committee review are exempt from the 30 days.
• Missing the deadlines triggers liquidated damages under Section E.29.2 or a corrective action plan.

The contract also tells prospective providers to submit credentialing applications "at least one hundred and twenty (120) days prior to initiating the delivery of services," which is the honest planning number: the 30 days starts only when the file is complete and the Medicaid ID is already in hand. BlueCare's own Provider Administration Manual (effective October 1, 2026) sets its enrollment goal at 60 calendar days and lists what it wants first: a CAQH profile attested no more than 90 calendar days before BCBST is given access, EFT enrollment, an Availity account, and, for groups in the BlueCare and TennCare Select networks, "a Medicaid ID from TennCare before applying with us." It also notes that a practitioner joining a contracted group must participate in every network the group holds. Wellpoint's Tennessee join page likewise credentials from CAQH ProView. National plans' steps are on our payer-by-payer credentialing hub.

For commercial plans Tennessee has had a credentialing statute for years. As published by FindLaw (current as of January 2, 2024; the official code could not be read today), Tenn. Code Ann. § 56-7-1001 requires a health insurance entity to notify a provider whether it will contract within 90 calendar days of receiving a clean CAQH application, and defines a clean application as one with no defect, misstatement or missing documentation. Subsection (f) adds a written status notice within 5 business days of receipt, a decision within 90 calendar days after the application is complete, and discontinuation if the applicant does not cure an incomplete file within 30 calendar days. It bars a new applicant from submitting claims while the application is pending, but once credentialing is approved held claims are paid at the in-network rate for the interim period. An insurer may not list a provider as in-network, or as pending, until the contract is signed by both sides.

Two limits matter for Medicaid. Subsection (f)(6) exempts TennCare, CoverKids and the other state-managed plans, which is why the 30-day contract clock above, not the statute, governs the MCOs. And SB 2436 in the 114th General Assembly, which would require approval within two weeks when an already-credentialed provider relocates to another group the insurer has credentialed, was referred to the Senate Commerce and Labor Committee on February 5, 2026 and showed no further action when we read the bill page.

Tennessee's Medicare Administrative Contractor is Palmetto GBA, LLC. CMS's A/B MAC Jurisdiction J page (modified July 8, 2026) says JJ "processes FFS Medicare Part A and Part B claims for Alabama, Georgia, and Tennessee" under contract 75FCMC24C0023, and Palmetto's EDI enrollment packet lists the same three states. Palmetto also holds Jurisdiction M next door (the Carolinas, Virginia and West Virginia), so a Tennessee practice with a Bristol or Chattanooga address on the wrong side of a state line can end up in the wrong queue; check which jurisdiction your practice location falls in before filing. The JJ Part B Provider Contact Center (page published January 17, 2025) takes enrollment questions at 877-567-7271, 8 a.m. to 6 p.m. Eastern, Monday through Friday, and the Contact Provider Enrollment page gives the documentation address: Palmetto GBA, Mail Code AG-310, P.O. Box 100306, Columbia, SC 29202-3306, or 2300 Springdale Drive, Building One, Camden, SC 29020-1728 for courier.

The enrollment itself is a CMS-855I or CMS-855B filed in PECOS, which Palmetto works against CMS's timeliness standard for every MAC: an online application with no site visit or development is finished 95% of the time within 15 calendar days and always within 50. Under 42 CFR 424.521 physicians and nonphysician practitioners may bill for up to 30 days before the effective date when circumstances kept them from enrolling sooner. Forms, PECOS and timelines are on our Medicare provider enrollment page. Remember TennCare's PECOS rule in reverse: the ownership data you file with TennCare has to match what Palmetto holds, and TennCare's revalidation page asks providers who bill Medicare to make sure each NPI is also enrolled with Medicare before revalidating.

Railroad Retirement Board beneficiaries' Part B claims go to Palmetto's separate Railroad Medicare unit. After JJ approves your enrollment, request a Railroad Medicare PTAN in the PTAN Lookup and Request Tool; Palmetto builds it from your Medicare record and asks you to allow up to 30 days. The same contractor and the same Medicaid-ID-first structure appear in our Georgia guide and Alabama guide, the two other JJ states.

Tennessee's process fails quietly, usually in the hand-off between systems rather than inside any one of them. What we check before a Tennessee file goes in:

• A CAQH profile that is not attested, or not shared. TennCare receives nothing until the profile is in attested status and TennCare is authorized; BlueCare separately wants attestation within the last 90 days.
• A CAQH profile missing a service location. TennCare pulls locations from CAQH, so a second office that is not in the profile is not in the enrollment.
• Ownership that disagrees with PECOS. TennCare returns the enrollment; fix PECOS first or update both the same week.
• A for-profit entity with fewer than three ownership lines, or an owner entered at 0%.
• An individual not linked to a group. The welcome letter issues only after the link, and a group that never added the clinician to its roster is the usual cause.
• An unread primary email. Error notices, the welcome letter and the 45-day revalidation notice all go there; the revalidation page asks you to confirm it.
• Applying to the plans before the Medicaid ID issues. The MCO contract says the application is not complete without it, so the 30-day clock never starts.
• Filing with one MCO. Members can only change plans in their region's month, so two plans' patients stay out of reach until then.

Our process is built around those hand-offs: one checked file compared field by field across the TennCare portal, CAQH, NPPES, PECOS and the Secretary of State before anything is submitted, then weekly follow-up with TennCare and each plan, with the representative's name, the date and the reference number logged.

Have these current before you start: each clinician's Type 1 NPI and the group's Type 2 NPI, with NPPES addresses matching the practice; the IRS letter for the legal name and FEIN; Tennessee professional licenses, verified on the Department of Health site; DEA and CLIA where they apply; malpractice coverage; the owners, directors and managing employees with percentages for a for-profit entity, matching PECOS; every service location; a CAQH login with the profile attested and TennCare authorized; EFT details for the plans; and the Medicare approval letter once Palmetto issues it.

If you are unsure which of these steps actually lets you bill, our explainer on what provider credentialing is separates enrollment, credentialing and contracting. The same process in a neighboring state: provider credentialing in Kentucky, where the portal is KY MPPA and the contractor is CGS.

ClaimCarePro registers providers and groups with TennCare, builds and attests the CAQH profile TennCare reads from, and credentials the practice with BlueCare, Wellpoint, UnitedHealthcare Community Plan and TennCare Select, plus Palmetto GBA Medicare, the Railroad Medicare PTAN, revalidation and the commercial plans, with weekly logged follow-up on every payer. Tennessee files are billed at our published flat prices: $250 per payer application per provider, CAQH setup $250, re-credentialing $250, maintenance $99 per provider per year, or the new-practice bundle at $1,750 per provider ($1,400 each additional provider on the same group and payers).
