Medicaid billing for mental health, substance use disorder (SUD), and Psychiatric Rehabilitation Programs (PRP) in Maryland runs under some of the most strictest rules in the country. Short timely-filing windows, Maryland-specific HCPCS codes, Carelon service authorizations, and rigorous COMAR audit standards make Maryland Medicaid revenue uniquely challenging.

IOU Billing delivers end-to-end Maryland Medicaid revenue cycle management and enrollment support. Our team includes specialists with direct hands-on experience inside Carelon — Maryland Medicaid’s behavioral health ASO — and the state Medicaid system. That means claims, maximum reimbursement, and compliance you can defend in an audit.

Deep Regional Maryland Medicaid Expertise

Unlike general billing companies that struggle with Maryland’s Medicaid quirks, IOU Billing’s team includes specialists who have worked inside Carelon and know exactly how Maryland auditors and MCO medical directors evaluate claims. That gives your facility a real advantage in clean collections.

Common questions

Straight answers, before you call

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

Why is Maryland Medicaid billing harder than commercial insurance billing?

Maryland Medicaid uses state-specific coding, specialized HCPCS/modifier combinations, and Carelon service authorization requirements. It also enforces significantly shorter timely filing deadlines and conducts rigorous post-payment COMAR audits. One documentation gap can trigger recoupments across months of claims.

Which Maryland Medicaid MCOs do you work with?

We manage enrollment and billing across Maryland HealthChoice MCOs, including Maryland Physicians Care, Priority Partners, UnitedHealthcare Community Plan, Aetna Better Health of Maryland, Wellpoint, Jai Medical Systems, MedStar Family Choice, and CareFirst Community Health Plan Maryland — plus Carelon for the public behavioral health system.

How do you help our practice prevent Maryland Medicaid audit clawback?

We audit claims before submission so the billed CPT/HCPCS code, units, renderer, and taxonomy match both the patient’s active Carelon authorization and COMAR regulations. Proactive scrubbing means paid claims stand up to post-payment state audits.

Can you help with new provider and facility Maryland Medicaid enrollment?

Yes. We manage full Maryland Medicaid group facility enrollment, individual rendering-provider enrollment, and rendering-to-group linkage across fee-for-service and MCO panels — so your clinicians are fully paneled before billing.
