Medicaid billing for mental health, substance use disorder (SUD), and psychiatric rehabilitation programs operates under some of the most stringent regulations in healthcare. Short timely filing windows, specialized state HCPCS codes, complex MCO authorizations, and strict audit rules make Medicaid revenue management uniquely challenging.

IOU Billing delivers end-to-end Medicaid revenue cycle management and enrollment support. Our team includes specialists who understand state-specific behavioral health framework rules inside and out—ensuring clean claims, maximum reimbursement, and ironclad compliance.

Deep Regional Medicaid Expertise

Unlike general billing companies that struggle with state-level Medicaid quirks, IOU Billing’s team includes specialists with direct experience inside regional behavioral health MCOs. We know exactly how state auditors and MCO medical directors evaluate claims, giving your facility an unprecedented advantage in clean collections.

what’s included:

State Medicaid & MCO Credentialing — Complete group facility and individual clinician enrollment across fee-for-service Medicaid and regional Managed Care Organizations (MCOs) like Carelon, Optum, and Aetna Better Health.
Specialized Behavioral Health Coding — Expert mapping of state-specific HCPCS codes (H-codes, T-codes), revenue codes, and required clinical modifiers for SUD, PRP, IOP, and residential services.
Service Authorization Tracking — Cross-referencing active treatment plans and state authorization approvals prior to claim generation to prevent non-authorized service denials.
Strict Timely Filing Management — Rapid claim scrubbing and electronic batch submissions to satisfy tight Medicaid filing deadlines (often 30, 60, or 90 days depending on the state).
Audit Defense & Compliance Safeguards — Pre-submission claim verification aligned with state rules (such as Maryland COMAR and BHA guidelines) to protect your practice against recoupments and clawbacks.
MCO Denial Resolution & Grievance Appeals — Direct resolution of MCO claim rejections, coordination with state medical directors, and formal clinical appeal filings for denied claims.

Operating a PRP, SUD, or Residential Medicaid Program?

Psychiatric Rehabilitation Programs (PRP), Intensive Outpatient (IOP), Substance Use Disorder (SUD), and residential facilities face intense regulatory oversight under state behavioral health authorities (such as Maryland’s BHA and COMAR regulations). IOU Billing’s Medicaid specialists help you set up compliant documentation workflows, navigate Carelon and Optum rules, and keep your billing operating without administrative interruptions.

Common questions

Straight answers, before you call

The questions practice owners and directors ask us most about Medicaid billing — answered plainly.

Why is Medicaid billing more complex than commercial insurance billing?

Medicaid relies on state-specific coding guidelines, specialized HCPCS/modifier combinations, and strict service authorization requirements. Additionally, Medicaid programs enforce significantly shorter timely filing deadlines and conduct rigorous post-payment audits. A single documentation gap can trigger recoupments across months of claims.

Which Medicaid Managed Care Organizations (MCOs) do you work with?

We manage enrollment and billing across all major state Medicaid programs and regional MCOs, including Carelon Behavioral Health, Optum, Aetna Better Health, AmeriHealth Caritas, Maryland Physicians Care, UnitedHealthcare Community Plan, and Priority Partners.

How do you help our practice prevent Medicaid audit clawback?

We audit claims prior to submission to ensure that the billed CPT/HCPCS code, units, renderers, and rendering taxonomy match both the patient’s active service authorization and state regulations (such as COMAR). This proactive scrubbing ensures that paid claims stand up to post-payment state audits.

Can you assist with new provider and facility Medicaid enrollment?

Yes. We manage complete Medicaid group facility enrollment, individual rendering provider enrollment, and rendering-to-group linkage across state fee-for-service systems and regional MCO panels—ensuring your clinicians are fully paneled before billing.
