# UnitedHealthcare Community Plan of Tennessee ABA coverage (TennCare MCO).

_Payer Guide · UHC Community Plan (TN) · Last updated September 2026 · 6 primary sources_

> Shared TennCare baseline + UHC's own Level of Care rules: physician order, 20-hr gate.

UnitedHealthcare Community Plan of Tennessee administers the TennCare ABA benefit under the shared tri-MCO program description — but unlike the other two MCOs, UHC layers its own Level of Care Guidelines (revised December 2024) on top. Those add real operational teeth: an explicit physician-order requirement, extra scrutiny for comprehensive programs above 20 hours/week, a device-attention test for telehealth ABA, and a three-month no-progress discharge rule. If a family carries UHC, plan the request against both documents.

This plan administers the **TennCare** ABA benefit: the state rules are the floor, and this page covers what the plan layers on top. Read it together with the [TennCare (Tennessee Medicaid) guide](https://carelu.com/payers/tenncare-tennessee-medicaid).

## Prior authorization and diagnosis at a glance

- **Prior auth for the assessment**: Required — universal form + comprehensive clinical evaluation AND a physician order recommending ABA [2][1]
- **Prior auth for treatment**: Required — initial + concurrent review; no measurable progress over 3 months can end medical necessity [2]
- **Autism diagnosis required?**: ASD or another qualifying DSM-5-TR diagnosis — not strictly autism-only [2]

## At a glance

- **Plan type:** TennCare MCO (UnitedHealthcare / Optum platform)
- **Clinical rules:** Shared tri-MCO program + UHC Level of Care Guidelines (12/2024)
- **Prior auth:** Required — universal form via Provider Express, fax, or secure email
- **Physician order:** Explicitly required for ABA initiation (strictest of the 3 MCOs)
- **Intensity gate:** >20 hrs/week comprehensive ABA gets extra scrutiny (severity 2–3, early in treatment)
- **Progress rule:** No measurable change over 3 months of optimal treatment ends medical necessity

## The UHC overlay: what it adds to the TennCare baseline

UHC's Level of Care Guidelines require a comprehensive clinical evaluation by a Tennessee-licensed clinician and a physician order or script recommending ABA before initiation — the most explicit ordering requirement among the TennCare MCOs. Comprehensive programs above 20 hours/week "should generally only be considered" when the member has multiple needs, is within roughly the first two years of ABA, and presents at DSM-5 severity level 2–3; intensity must also leave room for rest, family time, and other activities. And maintenance-phase ABA must step down: lower intensity, caregiver-training-focused, not full-time. [2]

## Authorization mechanics

Requests use the universal tri-MCO form, submitted via Provider Express, fax (877) 217-6068, or secure email (tn_medicaid_aba@uhc.com); the ABA line is (800) 690-1606. Authorization lengths are set per individual need (the universal form models 26-week periods), with reassessment at the end of each authorized period. Two rules to design intake around: caregiver training is required with a documented caregiver plan — refusal or non-participation is a discharge criterion — and direct telehealth ABA is only medically necessary when the member can attend to a device for an extended period. [1][5]

## Intake gates

The questions that decide whether a family can start with UnitedHealthcare Community Plan of Tennessee, and what they have to bring.

- **Age limit**: Follows the TennCare rule: EPSDT covers “children from birth through age 20 who have TennCare.” UHC’s own Level of Care Guidelines for ABA set no age limit — they instead add adolescent and young-adult content, directing that “when adolescents, young adults, or adults are receiving ABA services, it’s important to include a focus on transition to adulthood.” [6][2][1]
- **Diagnosis recency**: Follows the TennCare rule — no recency limit on the diagnosis itself, with updated functional evaluation by standardized tools expected at least every two years. UHC’s overlay puts its clock on progress rather than the diagnosis: “the patient must be reassessed at the end of each authorized period,” and “if the patient shows no meaningful measurable changes, on a norm based assessment, for period of 3 months of optimal treatment, then ABA may no longer be considered medically necessary.” [2][1]
- **Who may diagnose**: Stricter than the shared baseline. UHC requires “a comprehensive clinical evaluation by a TN licensed clinician supporting medical necessity for ABA” and that “the member has been assigned a DSM-5 TR diagnosis of Autism or another identified diagnosis for which ABA is the least restrictive and most clinically appropriate treatment.” The guidelines name no single license for the diagnostician, but the evaluation must be a TN-licensed clinician’s and must be separate from the physician order that follows it. [2]
- **Diagnostic tools required**: No named instrument, but a named battery. UHC requires that “assessments should include norm referenced assessments, skills assessments, a risk assessment, and a behavioral assessment,” and gates prior authorization on “a reasonable expectation on the part of a treating healthcare professional that the individual’s behavior will improve significantly, as measured by norm referenced assessments.” Progress and discharge decisions both turn on norm-referenced scores, so the instrument you choose at intake is the one you will be re-scored against at concurrent review. [2]
- **Referral required?**: The strictest of the three TennCare MCOs: “the member will need a physician order/script recommending ABA services, based on their review of the diagnostic assessment.” That order is an initiation criterion in its own right, on top of the comprehensive clinical evaluation, and the universal form’s “Doctor’s Order Attached” checkbox is where it lands. Chase it at intake, not at submission. UHC also notes that while “the initial evaluation may be ordered by the primary care provider or specialist, the number of hours proposed by the ABA provider must be substantiated as medically necessary.” [2][4]
- **Telehealth**: Per-code on the universal form, with a UHC-specific clinical gate on top: “direct Telehealth services may only be considered medically necessary when the provider has assessed that a member has core skills to attend to a device for an extended period of time.” The guidelines add that “telehealth service delivery for ABA should include an ongoing review of ethical, efficacy, and scope of practice considerations.” So document device-attention skills before requesting telehealth hours — it is a medical-necessity element, not a logistics preference. [2][4]
- **Prior-auth decision time**: UnitedHealthcare's 2026 TennCare manual sets the standard pre-service decision "Within 5 working days of receipt of medical record information required but no longer than 7 calendar days of receipt." Urgent/expedited pre-service decisions come "Within 3 days of request receipt." The TennCare contract caps expedited decisions at 72 hours from receipt and allows a 14-day extension on either track. Retrospective review takes "Within 30 calendar days of receiving all pertinent clinical information." ABA is requested through Optum Behavioral Health on the shared tri-MCO form, with 26-week authorization periods. Neither the manual nor the form publishes a reauthorization lead time. [7][8][9]
- **Other insurance (who pays first)**: UnitedHealthcare Community Plan "is, by law, the payer of last resort." You "must bill and obtain an EOB from any other insurance or health care coverage resource before billing," then "attach a copy of the EOB to the submitted claim." The EOB "must be complete to understand the paid amount or denial reason." At authorization, providers should "Determine if the covered person has other insurance that should be billed first." Unlike Wellpoint and BlueCare, the manual publishes no pay-and-chase list. It is also silent on whether the Optum ABA authorization is still needed when UnitedHealthcare is secondary. The TennCare contract lets the MCO deny a claim the primary plan denied for "failure to obtain prior authorization." Get the commercial PA. TRICARE by statute pays only after other coverage "except in the case of a plan administered under title XIX" (Medicaid), so TRICARE goes before TennCare. CHAMPVA is the reverse: "If you are eligible under Medicaid, CHAMPVA will pay first." [7][8][10][11]
  - Ask the plan: Optum Behavioral Health for UnitedHealthcare Community Plan of Tennessee (1-800-690-1606) — ask whether an ABA authorization is required when a commercial plan is primary, and whether ABA for members under 21 is paid first and recovered later.

## Delivery and billing rules

Coverage decides whether UnitedHealthcare Community Plan of Tennessee pays. These decide whether the claim survives: staffing and supervision, concurrent billing, per-day ceilings, who signs the note, where the service is payable, and whose NPI the claim goes out under.

- **Supervision**: “ABA services must be located in TN and must be provided by or supervised by a TN board-certified Behavior Analyst (BCBA) or a health professional permissible under TN state law. Unlicensed persons may deliver applied behavior analysis (ABA) services under the extended authority and direction of an LBA or an LABA who is supervised by an LBA. Such persons shall not represent themselves as professional behavior analysts.” UHC also splits the work by tier: assessment, plan development, revision, caregiver observation, effectiveness monitoring and on-site crisis assistance “may be performed by a Behavioral Analyst,” while only the last four may be performed by a Behavioral Specialist. No numeric ratio is published, so the shared program description’s incorporation of the BACB supervision requirements governs. [2][1]
- **Daily limits / MUEs**: No per-day unit ceiling, but the only real intensity gate among the TennCare MCOs: “High frequency/Comprehensive ABA (greater than 20 hours per week) should generally only be considered when the member has multiple needs related to behaviors and social communication challenges, is early in receiving ABA services (i.e. within the first 2 years of ABA), and has a symptom severity of at least 2 or 3 per DSM-V criteria.” Proposed intensity must also leave room for “appropriate rest breaks, nutrition breaks, family time and time for play or non-learning activities,” and maintenance-phase ABA “should be at a lower intensity of services… these programs should not be comprehensive or full time in nature.” Authorization length is set by the MCO to the individual’s needs. [2]
- **Place of service**: Follows the TennCare rule — Clinic, Home, Community, School, Telehealth and Other are all requestable on the universal form, and medically necessary school-based behavioral health services need not sit in an IEP to be reimbursable. UHC adds two conditions of its own: services “must be located in TN,” and “the rationale for services and schedule of treatment with location should be a part of the treatment plan” — so setting is a documented clinical choice, not a scheduling convenience. Treatment protocols are expected to be “implemented repeatedly, frequently, and consistently across environments until the client can function independently in multiple situations.” [2][1][4]
- **Bill as provider**: Follows the TennCare rule: the claim rides on the group or servicing provider identified on the universal form, with the practitioner level carried as a modifier — HO on analyst-delivered codes, HM on technician-delivered, and 97153 split between the two. UHC’s guidelines describe who may perform which component rather than whose NPI the claim carries, and no separate UHC rendering-versus-supervising convention is published for TennCare ABA. [4][2]
- **Concurrent billing (97153 + 97155)** _(ask the plan)_: Not answered for 97153 with 97155. The Level of Care Guidelines address intensity and medical necessity rather than claim edits, and the shared program description bars only two overlaps — more than one licensed analyst serving a member during a specific time interval, and ABA delivered simultaneously with OT, speech, PT or psychotherapy. [2][1]
  - Ask the plan: UnitedHealthcare’s TN ABA line (800) 690-1606 or tn_medicaid_aba@uhc.com, and the UHC Community Plan of Tennessee reimbursement policies on uhcprovider.com.

## What intake should collect for UnitedHealthcare Community Plan of Tennessee

- **Physician order for ABA:** UHC explicitly requires the order/script at initiation — chase it at intake, not at submission.
- **Comprehensive evaluation:** By a TN-licensed clinician; attach with the diagnostic report.
- **Severity level + time in ABA:** Requests above 20 hrs/week need severity 2–3 and early-in-treatment framing.
- **Caregiver participation commitment:** A documented caregiver plan is required; non-participation is a discharge criterion.
- **Telehealth suitability:** Direct telehealth ABA needs documented device-attention skills.

Code notes:

- **97153:** Continuation requests must report % of authorized units used on this code — under 90% requires a written explanation. UHC overlay: comprehensive programs above 20 hrs/week (across all direct-treatment codes combined) get extra scrutiny — expected only with multiple needs, roughly the first two years of ABA, and DSM-5 severity level 2-3.
- **97156:** Parent-training volume delivered is tracked separately at continuation. UHC overlay: a documented caregiver participation plan is required; non-participation is a discharge criterion.
- **0362T, 0373T:** Verify via: this MCO's provider services, or the Universal Request form's blank "Other" code line — the shared tri-MCO documents' own printed code lists stop at 97158.

### Contacts

- **Provider services phone:** (800) 690-1606 — the dedicated ABA authorization line, per the Tri-MCO ABA Overview of Updates ("For authorization requests, questions or submission, please contact: 800-690-1606"); UnitedHealthcare Community Plan of TN's general Provider Services line is (877) 222-6720, per the Universal Request form's "Additional MCO Contact Information" table

- **Fax:** (877) 217-6068

Questions to ask on a verification call:

- Is ABA administered directly by UnitedHealthcare Community Plan, or through a separate behavioral health vendor like Optum — and if a vendor, is there a second EDI hop for eligibility/benefits?
- Does this member's plan cover 0362T and 0373T in addition to the shared tri-MCO 97151-97158 code set?
- Can eligibility be checked in real time, or only via batch, for this payer ID?

## Common questions

### Does UnitedHealthcare Community Plan of Tennessee cover ABA?

Yes — it administers the TennCare ABA benefit (EPSDT, under 21) under the shared tri-MCO program description, plus UHC's own Level of Care Guidelines with additional requirements like an explicit physician order.

### How is UHC different from the other TennCare MCOs for ABA?

It's the only one with a distinct clinical overlay: physician-order requirement, extra scrutiny above 20 hours/week of comprehensive ABA, a device-attention test for telehealth, and a 3-month no-measurable-progress discharge rule.

### How do I submit a UHC TennCare ABA authorization?

The universal tri-MCO ABA request form via Provider Express, fax (877) 217-6068, or secure email tn_medicaid_aba@uhc.com; ABA line (800) 690-1606.
