Diagnostic Process Guide

Step 1: Visit Your PCP. Illinois PCPs can screen for adult ADHD and either diagnose or refer to a specialist. Most Illinois insurance plans cover an annual wellness visit that can include ADHD screening at no additional cost.

Step 2: Get a Referral if Needed. For HMO plans, a PCP referral is required for specialist visits. PPO plan members can self-refer. For Medicaid, your PCP or managed care plan can coordinate the referral.

Step 3: Verify Insurance Benefits. Call your insurer's behavioral health line. Confirm: in-network status of your chosen provider, prior authorization requirements, and your copay or coinsurance.

Step 4: Complete the Evaluation. Bring insurance card, photo ID, and any prior records. Evaluations typically include a clinical interview and standardized questionnaires. Comprehensive neuropsychological testing is available but may require separate authorization.

Step 5: Begin Treatment. In Illinois, psychiatrists, PCPs, and Advanced Practice Nurses (APNs) can prescribe ADHD medications. Illinois requires prescribers to check the Illinois Prescription Monitoring Program (PMP) before issuing controlled substance prescriptions.

Local Resources FAQ

How much cheaper is an ADHD evaluation downstate compared to Chicago?

Downstate evaluations (Springfield, Peoria, Champaign) typically cost $600-$1,200 -- roughly 40-50% less than comparable evaluations in Chicago and its suburbs ($1,000-$2,500). University training clinics downstate offer the lowest rates at $100-$400.

Does Illinois Medicaid require prior authorization for ADHD medication?

Illinois Medicaid covers most generic ADHD medications (methylphenidate, amphetamine salts) without prior authorization. Brand-name medications like Vyvanse or Concerta may require prior authorization or a step therapy protocol (trying a generic first). Your prescriber can submit a prior authorization request if a specific brand is clinically necessary.

Can I get a same-day ADHD prescription from a Chicago urgent care or walk-in clinic?

Generally, no. Walk-in clinics and urgent care centers in Illinois are not the appropriate setting for an initial ADHD diagnosis or controlled substance prescription. ADHD evaluation requires a structured clinical assessment with a qualified provider. However, some telehealth platforms can offer evaluations within 1-2 weeks, which is faster than most in-person options.
