About

Kestrel ABA

Read full description

Kestrel watches the payers you bill so you don't have to. For BCBAs and ABA clinic owners, a single quiet change to a Medicaid or commercial payer's policy — a new prior-authorization requirement, a revised fee schedule, a modifier rule, a change to covered CPT codes — can mean denied claims, failed audits, and lost revenue. These changes are buried in hundreds of provider manuals, bulletins, and fee schedules across all 50 states. Nobody has time to check them all. Kestrel does it for you, every day. WHAT KESTREL DOES • Monitors official Medicaid and commercial payer policy documents nationwide — provider manuals, bulletins, fee schedules, and coverage policies for ABA services. • Detects the moment a rule that affects ABA billing actually changes. • Sends a clear, plain-English alert: what changed, what it means for how you bill, the effective date, and a link to the source document. BUILT FOR HOW YOU WORK • Follow only the payers and states you care about — your alerts are scoped to your caseload. • Severity that respects your time: urgent billing changes notify you immediately; everything else arrives in a single daily digest. No noise. • Every alert is grounded in the source, linking straight to the official document so you can verify before you act. ASK KESTREL • Have a question about a payer's ABA policy? Ask in plain English and get an answer with citations to the exact documents — prior-auth rules, unit limits, covered codes, telehealth policies, and more. • If your payers' documents don't cover it, Kestrel says so instead of guessing. WHO IT'S FOR Board Certified Behavior Analysts (BCBAs), ABA clinic owners and administrators, and billing teams responsible for keeping a practice compliant and paid. SUBSCRIPTION Kestrel Pro is an auto-renewable subscription — $14.99/month, with a 3-day free trial. It unlocks unlimited alerts, full payer and state coverage, and Ask Kestrel.
