Prior Authorization

Diagnosis and authorization: Illinois Medicaid covers medically necessary Adaptive Behavior Support (ABS) services for eligible members under age 21 with autism spectrum disorder.

How Our Multi-Payer ABA Billing Services Handle Different Payers
Our multi-payer ABA billing services are built to reduce avoidable denials, prevent authorization-related billing errors, and keep claims moving across different insurance plans.
At Cube Therapy Billing, we do not use one billing process for every payer. We adjust claim setup, authorization checks, modifiers, provider details, and follow-up based on the specific rules of each commercial payer, Medicaid program, and managed care plan.
New Jersey's autism mandate requires state-regulated plans to cover medically necessary ABA. It took effect in February 2010 and is one of the stronger mandates in the country.
The original under-21 age cap and the 30-visit limits on OT, PT, and speech came off through later amendments, so adults with autism can now access covered ABA under state-regulated plans.
Illinois law requires applicable state-regulated insurance plans to cover autism diagnosis and treatment for individuals under age 21, subject to statutory coverage terms. Self-funded employer plans may follow different federal requirements.
Under Illinois HFS rules, CPT codes 97153–97158 require prior authorization, while 97151–97152 require authorization when assessment services exceed six hours.
Payer policies change often. Cube therapy billing verifies the current version of each payer's policy, fee schedule, and authorization requirements at intake and monitors updates for every client. The summary above reflects publicly posted payer policy at the time of writing and is not a guarantee of coverage.

What We Handle for Illinois ABA Therapy Practices
One team owns your full billing cycle. Nothing falls between vendors, and nothing depends on one overworked in-house biller.
01
Eligibility and benefit verification
Every client verified before intake: plan type, ABA benefit, deductible status, and whether the state mandate applies. No surprises at claim time.
02
Prior authorization management
We track approved dates, CPT codes, units, renewal activity, and payer requirements so authorization information stays connected to billing.
03
Clean claim submission
97151 through 97158, 0362T, 0373T, correct modifiers, correct rendering NPI, per each payer's rules. That's how we hold a 98.9% clean claim rate.
04
Root-cause denial management
Denials get worked in 24 to 48 hours, and the cause gets fixed upstream so the same denial doesn't come back next month.
05
AR follow-up and payment posting
Aggressive follow-up on every unpaid claim, ERA posting, and underpayment catches against your contracted rates.
06
Credentialing and MCO enrollment
We support payer enrollment, CAQH maintenance, credentialing, revalidation, and related setup so provider participation stays aligned with billing.
How switching works
From first call to first clean claim batch
Switching billing partners feels risky. Our onboarding is built so your cash flow never skips a cycle.
01
Billing review call
We look at your current AR, denial patterns, and payer mix. You get honest findings on the call, whether or not you sign.

Setup inside your EHR
Role-based access in your existing system. CentralReach, AlohaABA, Rethink, and 20+ others. No data migration drama.
03

04
Claims go live
New claims submitted clean under each payer's current NJ rules while we work your aging AR in parallel.

Denials worked at the root
Each denial gets appealed fast and traced back to its cause. Denial rate trends down month over month.

Weekly visibility into claims, collections, AR aging, and auth status through SparkzABA. No mystery deposits.
Why choose Cube
Why Illinois ABA Practices Choose to Work With Us
We understand Illinois Medicaid (HFS) billing rules, HealthChoice Illinois MCO requirements, and ABA claim challenges. Our team helps practices reduce denials, manage authorizations, and improve collections.
ABA-specialized, not general medical billing
Our team lives in 97151 to 97158, concurrent billing rules, supervision modifiers, and authorization cycles. Your claims aren't learning material for a generalist biller.
Built Around Illinois Medicaid HFS Rules
Illinois ABA billing involves Adaptive Behavior Support (ABS) requirements, prior authorizations, treatment plans, provider qualifications, and supervision documentation. We review claims against HFS and payer-specific requirements before submission.
First in the industry
SparkzABA: AI powered RCM workflow management
Every Cube client runs on SparkzABA, our RCM workflow management software with AI powered workflows, the first of its kind in the ABA billing industry. It tracks every claim, authorization, credentialing file, and eligibility check in real time, flags risks before they become denials, and gives you a live window into your revenue instead of a month-old PDF report.
Proactive denial prevention
We catch problems before claims go out: missing auths, wrong modifiers, unit overages against Horizon's daily limits. That's how our denial rate stays under 3%.
Credentialing and billing under one roof
From Illinois Medicaid IMPACT enrollment and HealthChoice Illinois MCO credentialing to CAQH updates, authorizations, claims, denials, and A/R recovery, we manage your complete billing cycle.
Transparent reporting, HIPAA-compliant operations
Signed BAAs, role-based access, 2FA, and reporting that shows real numbers. You always know your clean claim rate, AR days, and what we're chasing this week.

Illinois ABA Therapy Billing Questions
These are the questions ABA practice owners actually ask us on the first call.
ABA medical billing covers the full insurance billing process for applied behavior analysis services. That usually includes eligibility verification, prior authorization tracking, claim preparation, CPT and modifier review, claim submission, payment posting, denial management, AR follow-up, and credentialing support. The goal is to make sure the service delivered, the authorization, the documentation, and the claim all match before the payer processes it. Cube Therapy Billing already structures its ABA billing services around that full revenue cycle.
Cube Therapy Billing works with the core ABA CPT code set, including 97151 through 97158, along with 0362T and 0373T where applicable. Claims are reviewed for coding, modifiers, rendering provider details, place of service, authorization, and payer-specific requirements before submission.
Yes. Cube manages ABA prior authorizations by tracking approved units, authorization dates, payer requirements, and upcoming expirations to help prevent avoidable claim denials. We also coordinate authorization details for different care settings, including Virtual ABA Therapy in New Jersey, where coverage and approval requirements may vary by health plan.
Yes. Cube’s denial management process includes reviewing the denial reason, correcting claim issues, appealing when appropriate, following up with the payer, and identifying the root cause so the same denial is less likely to repeat. The site positions denial work as part of the full billing cycle rather than simple claim resubmission.
Yes. Cube works with Medicaid programs, Medicaid managed care plans, and commercial payers. On its current site, Cube specifically references payer experience that includes Medicaid MCOs and commercial insurers such as Aetna, Cigna, UnitedHealthcare, and BlueCross BlueShield.
Yes. Aging AR cleanup is usually part of onboarding. We audit unpaid claims, rework what's recoverable within timely filing limits, and give you an honest write-off recommendation on what isn't. Many practices recover meaningful revenue from claims they'd assumed were dead.
In most cases, yes. Cube says it works with more than 25 EHR and practice-management systems, including platforms such as CentralReach, AlohaABA, Rethink, Lumary, and Theralytics. The goal is to work inside the practice’s existing setup rather than force a full system migration.
