Wellmark Blue Cross and Blue Shield is Iowa's dominant commercial carrier, and for ABA it is also the least transparent one: its behavioral health provider guide is behind a provider login, its public code-level Medical Authorization Table lists no ABA or behavioral-health codes at all, and its public medical-policy index lists no ABA policy. So the public floor for a Wellmark family is the Iowa mandate itself, which changed on January 1, 2026: H.F. 330 (2025 Iowa Acts ch. 162) struck the mandate's age limits and dollar caps for large-group and public-employee plans issued or renewed on or after that date. The first intake question on every Wellmark card is therefore which kind of plan it is.
Iowa Code section 514C.31 requires a "group policy, contract, or plan" to cover "applied behavior analysis provided by a practitioner to covered individuals for the treatment of autism spectrum disorder pursuant to a treatment plan" when it is issued to an employer that employed "more than fifty full-time equivalent employees" on at least half its working days in the prior year, or is a chapter 509A plan for public employees other than State of Iowa employees. State employees are covered separately by section 514C.28, which reaches both the diagnostic assessment and treatment of autism. Until 2026 both sections had age limits (under 19 and under 21) and dollar caps ($36,000 a year to age six, $25,000 for ages seven to 13 and $12,500 for ages 14 to 18 under 514C.31; a $36,000 CPI-indexed cap under 514C.28). H.F. 330 struck them for plans "delivered, issued for delivery, continued, or renewed in this state on or after January 1, 2026," and amended section 514C.22 so that a covered group plan "shall not impose an aggregate annual or lifetime limit on biologically based mental illness coverage benefits for autism spectrum disorder." Visit limits were already barred.[1][2][3][4]
What the mandate still allows: deductibles, copayments and coinsurance that apply to other medical services, and "care management provisions ... including prior authorization and prior approval." The practitioner must be a licensed physician, a licensed psychologist, or a behavior analyst licensed under chapter 154D, and the treatment plan must be developed by a licensed physician or psychologist after a comprehensive evaluation consistent with the American Academy of Pediatrics. The plan may review a treatment plan "not more than once every three months during the first year" and then no more than every six months, at its own cost, and "shall not change the provisions of a treatment plan until the completion of a review." The mandate does not reach individual policies or small-group plans (section 514C.22 makes ASD a covered biologically based mental illness for small-group plans that cover mental illness, but does not name ABA), and self-funded employer plans answer to ERISA.[1][2][3][4]
Wellmark's public medical-policy index is an alphabetical list of medical policies; it contains no ABA policy. The page says InterQual criteria are used "to evaluate whether a medical procedure or equipment is medically necessary," and points to the Authorization Table as "your first stop in learning whether an authorization is required." That table carries no ABA rows: searched on 2026-10-11, 97151 through 97158, 0362T, 0373T, H2019 and even 90791 return nothing, so it cannot tell you whether ABA needs review. Behavioral health rules live in the Behavioral Health and Chemical Dependency section of the Wellmark Provider Guide, updated August 2026, which is served from a provider-only location and returned no public copy. We therefore do not state Wellmark's ABA criteria, unit limits or telehealth rules on this page. Treat every clinical-policy question as a verification call, and cite the mandate when a plan subject to it applies an age or dollar limit.[8][9][14]
Iowa licenses behavior analysts and assistant behavior analysts under Iowa Code chapter 154D, administered by the Board of Behavioral Health Professionals. A license is granted "upon submitting to the board proof of the applicant's current certification as a behavior analyst or behavior analyst-doctoral by a certifying entity" (the BACB or another NCCA- or ANSI-accredited body); assistant analysts must also show "ongoing supervision by a licensed behavior analyst." Technicians need no license: chapter 154D exempts "paraprofessional technicians who deliver applied behavior analysis services under the extended authority and direction of a licensed behavior analyst or licensed assistant behavior analyst," who must use titles such as "behavior technician."[5][6]
For fully insured plans, Iowa Code 514F.8 sets the prior-authorization clock: a determination "within forty-eight hours after receipt for urgent requests," "within ten calendar days after receipt for nonurgent requests," or fifteen days for complex cases or unusually high volume, with a receipt to the provider within 24 hours. An approved authorization is valid "for not less than ninety days," and a plan may not revoke or restrict it after the service has been delivered, except for listed reasons such as fraud, loss of coverage, or coordination of benefits. Self-funded plans follow the federal ERISA claims rule instead. Commercial ABA rates are negotiated in your Wellmark contract and are not published.[5][6]
Wellmark has not published one. Its public medical-policy index has no ABA policy. The page says InterQual criteria are used "to evaluate whether a medical procedure or equipment is medically necessary." Behavioral health rules sit in the provider-only Behavioral Health and Chemical Dependency section of the Wellmark Provider Guide (updated August 2026), which returned no public copy. Iowa's ABA mandate (§ 514C.31) defines a treatment plan by who writes it and on what evaluation, not by goal format. Ask Wellmark which criteria and treatment-plan template the reviewer applies.[8][9]
No Wellmark parent-training requirement or hours figure is public, for the same reason: the behavioral health section of the Provider Guide is provider-only, and the medical-policy index has no ABA policy. Confirm with Wellmark whether 97156/97157 are authorized separately and in what amount.[8][9]
Iowa requires insurers and HMOs to “either accept and pay or deny a clean claim” (Iowa Code § 507B.4A), and the Insurance Division’s rule sets the clock: within 30 days after the insurer receives the claim, with any request for information needed to make it clean due within the same 30 days (191 IAC 15.32(2)). A clean claim not paid within 30 days carries 10% annual interest from the thirty-first day. The rule applies to policies issued, delivered or renewed in Iowa. These statutes bind fully insured plans issued in the state; a self-funded employer plan (ERISA) is not subject to them and follows its plan documents and your contract.[10][11]
Wellmark says BlueCard "typically applies when a provider contracted with Wellmark is servicing a member of another BCBS Plan." Claims go through the treating provider's local plan. A Wellmark provider "submits the claim to Wellmark," and Wellmark "recognizes the BlueCard member and transmits the claim to the member's BCBS Plan," which "adjudicates the claim according to member's benefit Plan." Wellmark then reimburses the provider. Its filing tips: "File the claim to the provider's local BCBS Plan," and "Verify BlueCard member benefits, check applicable medical policies and initiate an out-of-area member authorization." Network status follows the ID card. A PPO-lettered suitcase means the provider "will be reimbursed for covered services in accordance with the provider's PPO contract with the local BCBS Plan." A blank suitcase marks HMO or POS coverage, where "Out-of-network benefits may be available." No suitcase means no BlueCard coverage.[12][13]
When a Wellmark member is treated outside Iowa and South Dakota, the provider checks eligibility "through your local BCBS Plan's website," using the first three characters of the Wellmark ID, or calls 800-676-2583. For pre-service review, "Providers outside Iowa and South Dakota seeing Wellmark members should log in to their local plan website and navigate to the out-of-state pre-service review information page." Non-Wellmark providers can instead "call the number on the member's ID card." Wellmark warns that for services on its Authorization Table, "If the prior approval is not approved or not completed prior to the service being provided, the claim will be denied." Whether ABA codes are on that table for a given member is the open question this guide records under prior authorization.[12][13]
The questions that decide whether a family can start with Wellmark Blue Cross and Blue Shield of Iowa, and what they have to bring. Each maps onto something intake should ask on the first call.
Iowa's COB rule governs fully insured plans: for a child whose parents are married or living together, "the plan of the parent whose birthday falls earlier in the calendar year is the primary plan; or if both parents have the same birthday, the plan that has covered one of the parents the longest is the primary plan"; for divorced or separated parents, a court decree naming the responsible parent controls. Self-funded plans follow their plan document. If the child also has Medicaid, Wellmark pays first (Medicaid is payer of last resort under 42 CFR 433.139); TRICARE pays after Wellmark ("TRICARE last pay," 32 CFR 199.8) and "CHAMPVA is the last payer to OHI" (38 CFR 17.276(d)).[7][16][17][18]
Depends on the plan. For large-group and non-state public-employee plans (§ 514C.31) and the State of Iowa employee plan (§ 514C.28) issued or renewed on or after January 1, 2026, the mandate has no age limit: H.F. 330 struck "under nineteen years of age" and "under twenty-one years of age." Plans renewed earlier keep the old limits until renewal. Individual, small-group and self-funded plans follow their plan documents.[1][4]
Ask the plan: Wellmark Provider Services: confirm group size, funding type and plan renewal date for the member.
Only the State of Iowa employee plan has a statutory rule: under § 514C.28 "the results of a diagnostic assessment of autism spectrum disorder shall be valid for a period of not less than twelve months, unless a licensed physician or licensed psychologist determines that a more frequent assessment is necessary." Wellmark's own rule for other plans is not public.[2]

For the State of Iowa employee plan, the diagnostic assessment is performed by "a licensed physician, licensed physician assistant, licensed psychologist, or licensed registered nurse practitioner" (§ 514C.28). Under § 514C.31 the treatment plan must come from a licensed physician or psychologist after a comprehensive evaluation. Wellmark's own diagnosing-provider rule is not public.[2][1]

The mandate requires a treatment plan developed by a licensed physician or licensed psychologist "after a comprehensive evaluation or reevaluation" (§ 514C.31), which functions as the order. Whether Wellmark also requires a separate referral is not public. The statute defines "treatment plan" as one "developed by a licensed physician or licensed psychologist after a comprehensive evaluation or reevaluation performed in a manner consistent with the most recent clinical report or recommendations of the American academy of pediatrics." It sets no expiry on the plan, but caps how often the carrier may review it: "not more than once every three months during the first year of the treatment plan and not more than once every six months during every year thereafter," unless the plan and the treating physician or psychologist agree otherwise.[1]
Ask the plan: Wellmark Provider Services and the member's benefit document.
Set by law, by funding type. Fully insured Wellmark plans follow Iowa Code 514F.8: a determination "within forty-eight hours after receipt for urgent requests," "within ten calendar days after receipt for nonurgent requests," or "within fifteen calendar days" for complex cases or unusually high volume, with a receipt to the provider within 24 hours; an approval is valid "for not less than ninety days" and cannot be revoked after the service is delivered except for listed reasons. The mandate also limits treatment-plan reviews to once every three months in the first year and once every six months after. Self-funded plans follow ERISA: a pre-service decision "not later than 15 days after receipt of the claim" (one 15-day extension) and 72 hours for urgent care.[6][1][15]
Ask the plan: Wellmark Provider Services: ask whether the plan is fully insured or self-funded, and how far before expiry Wellmark wants the ABA reauthorization.

Coverage decides whether Wellmark Blue Cross and Blue Shield of Iowa pays. These decide whether the claim survives: how sessions must be staffed and supervised, what may be billed concurrently, the per-day ceilings, who signs the note, where the service is payable, and whose NPI the claim goes out under.
No Wellmark standard is public. The legal floor: technicians practice only "under the extended authority and direction of a licensed behavior analyst or licensed assistant behavior analyst" (Iowa Code 154D.4), and under § 514C.31 the covered "treatment plan" includes supervisory services. No ratio is set by statute.[5][1]

Not published publicly by Wellmark. Iowa's mandates say coverage is not required "solely based on inclusion of the service in an individualized education program" (§ 514C.28) and do not affect obligations under an IFSP or IEP (§ 514C.31); they neither require nor bar school-setting ABA.[2][1]
Ask the plan: The member's benefit document and Wellmark Provider Services.
Not published publicly by Wellmark. Under § 514C.31 the covered practitioner is a licensed physician, a licensed psychologist, or "a behavior analyst licensed pursuant to chapter 154D"; technicians are unlicensed paraprofessionals under chapter 154D, so their work is billed through the licensed analyst in practice.

For large-group (more than 50 FTEs) and public-employee plans, Iowa law requires ABA coverage for autism under Iowa Code § 514C.31 or § 514C.28. For individual, small-group and self-funded plans, the plan document decides. Wellmark's ABA policy is not public, so verify each member.
Not for plans issued or renewed on or after January 1, 2026. H.F. 330 (2025) removed the under-19 and under-21 age limits and the $36,000 / $25,000 / $12,500 annual ABA maximums, and barred annual or lifetime limits on autism benefits. Plans that have not renewed since then may still apply the old caps until renewal.
For fully insured plans, Iowa Code 514F.8 requires 48 hours for urgent and 10 calendar days for non-urgent requests (15 for complex cases), and an approval lasts at least 90 days. Self-funded plans follow ERISA: 15 days, or 72 hours if urgent.
Wellmark publishes no ABA policy or treatment-plan template. Its behavioral health rules are in a provider-only Provider Guide section, so confirm the format with Wellmark.
None published. Confirm with Wellmark whether 97156/97157 are authorized and in what amount.
Iowa law (Iowa Code § 507B.4A; 191 IAC 15.32) requires a fully insured plan to pay or deny a clean claim within 30 days of receipt, with 10% annual interest after that. Self-funded employer plans are not bound by the statute.
The out-of-state provider files the claim with its own local Blue plan, which sends it to Wellmark to adjudicate on the member's benefits. Check eligibility through your local Blue's website with the Wellmark prefix, or call 800-676-2583. Find Wellmark's pre-service review requirements through your home plan's out-of-state pre-service review page, or call the number on the member's card. Wellmark denies claims for listed services when prior approval was not obtained first.
