TennCare Plans Share One ABA Rulebook. UHC Allows 3 Months Without Gains, Wellpoint 6

TennCare's three managed care plans publish one joint ABA program description, which we covered in September. That document doesn't say when a lack of progress ends care. The plans' own medical necessity guidelines do, and they don't agree. UnitedHealthcare Community Plan of Tennessee says ABA "may no longer be considered medically necessary" after 3 months without meaningful measurable change. Wellpoint Tennessee says six.

Same words, different clock

The two guidelines share most of their language, which makes the difference easy to miss. Both require reassessment at the end of each authorized period showing "measurable changes in the frequency, intensity and/or duration of the specific behavior of interest." Both define "optimal treatment" the same way: well-designed interventions from qualified staff "without significant interfering events such as serious physical illness, major family disruption, change of residence." Both say changes count only if they last beyond the session and generalize to home and community.

Then they split.

• UnitedHealthcare (Level of Care Guidelines, last revised December 13, 2024): no meaningful change "on a norm based assessment, for period of 3 months of optimal treatment."
• Wellpoint (ABA Medical Necessity Clinical Guidelines, revised June 24, 2024): no meaningful change "for six months of optimal treatment." Wellpoint authorizes continued care "for up to six months at a time," and separately lists discharge when a client "does not demonstrate progress towards goals for two or more successive authorization periods."

Other differences that change a request

• UnitedHealthcare, hours: more than 20 hours a week "should generally only be considered" when the member has multiple needs, is "within the first 2 years of ABA" and has "a symptom severity of at least 2 or 3 per DSM-V criteria." That ties hours to the severity level CMS also wants to use.
• UnitedHealthcare, telehealth: direct telehealth is medically necessary only when the provider has assessed that the member "has core skills to attend to a device for an extended period of time."
• Wellpoint, maintenance: a request for maintenance-only ABA needs "documented member barriers that necessitate continued ABA therapy."
• Wellpoint, gaps: for a gap in services longer than 90 days, contact the plan, because "a re-evaluation for care may be indicated."

The limits

Both guidelines say ABA "may" no longer be medically necessary, so neither clock is an automatic cutoff. Neither document is new. Both are the versions the plans link from their Tennessee provider pages today. We couldn't open BlueCare's continued-care guideline, so we don't know which clock, if any, the third plan uses.

What you must know or do

• Clinical directors: sort TennCare clients by plan. For each UnitedHealthcare client, check whether the last norm-based assessment shows change within the past three months. If it doesn't, the next reauthorization needs to show what changed in the intervention.
• When illness, a move or family disruption interrupted treatment, write it in the progress report. Both plans exclude those periods from "optimal treatment," but only if the record shows them.
• UnitedHealthcare requests over 20 hours a week: state the years in ABA and the DSM severity level in the request.
• Wellpoint maintenance requests: name the barriers. Call the plan before any break in services longer than 90 days.
