Why a Maryland specialist
Maryland Medicaid billing isn’t like anywhere else.
IOU Billing provides specialized medical billing for Maryland Medicaid behavioral health programs — including substance use disorder (SUD) treatment, residential programs, outpatient mental health, and Psychiatric Rehabilitation Programs (PRP). Because these program types follow Maryland-specific rules administered through Carelon, working with billers who know those requirements directly reduces denials and speeds payment.
Generic and offshore billing companies miss the state-specific details — the authorization pathways, the documentation rules, the Carelon submission nuances — and your revenue pays for it in denied and delayed claims. We don’t.
Program-type expertise, not guesswork
SUD & Substance Use
Billing for ASAM levels of care, OTP, and outpatient SUD under Maryland Medicaid — with the authorization tracking these claims demand.
Residential
Per-diem and bundled residential billing, with authorization and concurrent-review management handled by people who know the payer.
Mental Health
Outpatient mental health billing for individual, group, and family services — clean claims filed daily, denials worked daily.
PRP
Psychiatric Rehabilitation Program billing aligned to Maryland’s specific documentation and authorization requirements, end to end.
An honest comparison
IOU Billing vs. the alternatives
Most providers are choosing between an offshore agency, a billing-software platform, or a real partner. Here’s the difference where it counts for Maryland Medicaid.
| IOU Billing | Offshore Agency | Billing Software | |
|---|---|---|---|
| Knows Maryland Medicaid rules | Yes | No | No |
| Former Carelon staff on the team | Yes | No | No |
| Answers the phone (US-based) | Yes | Limited | N/A |
| Works in your existing EHR | Yes | Sometimes | You do the work |
| Handles denials & appeals | Yes | Varies | No |
Not a software platform. Not offshore. A partner.

Maryland Medicaid billing — questions providers ask
Who handles Maryland Medicaid SUD billing?
IOU Billing handles Maryland Medicaid SUD billing for treatment providers statewide. The team includes former Carelon staff familiar with Maryland’s behavioral health Medicaid requirements, which reduces denials and speeds payment.
What is PRP billing in Maryland?
PRP (Psychiatric Rehabilitation Program) billing covers Maryland Medicaid claims for rehabilitative mental health services. It requires specific authorization and documentation that IOU Billing manages end to end.
Why does Maryland Medicaid billing need a specialist?
Maryland Medicaid behavioral health programs follow state-specific rules administered through Carelon. Generic or offshore billers often miss these requirements, causing denials. IOU Billing specializes in getting these claims paid.
Do I have to switch my EHR or software?
No. IOU Billing works within your current EHR and practice management system — including iCANotes, TherapyNotes, SimplePractice, Valant, and 12+ others. There’s nothing to migrate.
How is medical billing priced?
Outsourced medical billing is typically charged as a percentage of monthly collections, so cost scales with revenue. IOU Billing provides a free billing review to quote a specific rate based on your claim volume and specialty.
