Billing Expertise Built Around Your Specialty
Every specialty has its own coding rules, payer requirements, and documentation standards. Our teams are trained specifically for each one — so nothing falls through the cracks.
ABA billing is built on unit-based claims, strict authorization tracking, and payer-specific coverage rules. We manage every session code, supervision ratio, and prior auth renewal so your BCBA team stays focused on clients, not paperwork.
Behavioral health practices deal with telehealth claim rejections, mental health parity disputes, and high denial rates from commercial payers. Our billing team handles appeals, resubmissions, and follow-up so your collections stay consistent.
Pediatric billing involves well-child visits, vaccine administration codes, dual-coverage coordination, and Medicaid compliance. We handle the full billing cycle for pediatric practices to keep claim approval rates high and payment timelines short.
Mental health billing is frequently delayed by missing authorization, incorrect session codes, or payer-specific documentation gaps. We verify benefits upfront, submit clean claims, and follow up aggressively on every pending payment.
PT practices lose revenue to therapy cap limits, functional reporting errors, and KX modifier issues. Our billers stay current with CMS therapy rules and payer contract updates so every claim goes out clean and gets paid on time.
OT billing requires precise procedure code selection, accurate units, and strong medical necessity documentation. We manage every part of the billing process from charge entry to ERA posting so your OTs can focus entirely on patient outcomes.
Denied Insurance Payments Claimed Back. Revenue Fully Recovered.
A real look at how MZ Medical Billing recovered nearly $40,000 for a mental health provider after a major insurance recoupment threatened to permanently wipe out months of earned revenue.
The provider originally submitted claims using the insurance details available at the time of verification, and Anthem processed and paid them without issue. Months later, Anthem issued a recoupment request and reversed those payments — stating the claims needed to be billed under a different active policy the member had never disclosed.
Our team made repeated attempts to verify the member's correct coverage. Each time, the member confirmed no other active insurance existed on the dates of service. After persistent escalation through multiple channels, Anthem finally confirmed that a separate active Anthem student plan had in fact been in force the entire time — information the payer had never communicated.
Corrected claims were submitted immediately on 01/21/2026 — but the payer denied them for exceeding timely filing limits. The delay had been caused entirely by the recoupment investigation and the payer's own failure to confirm the correct policy. The provider was now at risk of permanently losing tens of thousands of dollars despite acting correctly at every step.
"This case demonstrates how complex insurance discrepancies, recoupments, and timely filing denials can threaten provider revenue — especially in mental health billing. By combining detailed eligibility investigation, structured appeal documentation, and persistent payer follow-up, MZ Medical Billing successfully overturned the denial and recovered nearly $40,000 that was at risk of being permanently lost."

Heard Directly from the Practices We Serve
These are the words of real practice owners and administrators who trusted MZ Medical Billing to turn their revenue cycle around.
We had no idea how much revenue we were losing every month until MZ did our audit. Within 90 days they had recovered more than we thought was even possible. Our AR days went from 62 to 17. I wish we had made this move three years earlier.
ABA billing is incredibly specific and most billing companies just don't get it. MZ not only understood our authorization structure and unit limits — they built a tracking system that has completely eliminated our expired auth problems. Our denials dropped by over 80%.
Our mental health practice was in serious trouble financially even though our schedule was full. MZ identified that we had nearly $300,000 in recoverable claims sitting untouched. They recovered most of it in four months and rebuilt our entire billing workflow. We now have full clarity on where every dollar stands.
