Senior ABA Billing Specialist
Bill ABA correctly the first time: the right code, the right units, against a live authorization and a signed note.
The role
What this job actually is
Mastery of the RCM metric set is mandatory: net collection rate, gross collection rate, days in AR, AR over 90 days, denial rate, first-pass resolution rate, clean claim rate, cost to collect, charge lag and DNFB. You must be able to read them, explain what moves them, and act on them.
You own ABA claim production for a set of clients: matching every session to its authorization, confirming units and rendering provider, and getting the claim out clean. ABA denials usually trace to one of three things, a unit mismatch, a rendering configuration error, or an expired authorization, and your job is to catch all three before submission. Use BCBA and RBT terminology precisely; it drives the billing rules.
Ownership
What you will own
Clean ABA claim production
Correct CPT (97151, 97153, 97155, 97156, 97158 and Category III where required), units and modifiers.
Three-way matching
Authorization, session note and claim must agree before the claim goes out.
Rendering integrity
Ensure the rendering provider configuration matches what the payer expects for RBT versus BCBA delivered services.

Convert time to units correctly and never bill past the authorized balance.
Denial prevention
Track recurring ABA denial causes and eliminate them at the source.
Client rule currency
Keep payer-specific and client-specific billing rules documented and current.

Why ASP-RCM
Why this seat is different
We are senior-led by design. A senior partner is named on accounts and shows up in the work, which is why clients renew and why this role carries real authority rather than a title. Our AI suite is in production, not in a roadmap deck, and our compliance posture is independently audited: SOC 2 Type II with HITRUST, ISO 27001 and HIPAA.
We pay for certifications and run upskilling cohorts, because coding and revenue cycle are crafts that need investment. You will work across Dallas HQ, six US states and Chennai, India, with colleagues who have run these functions at scale.
