Maryland Medicaid and Columbia routing.
Maryland Medical Assistance Program covers ABA billing for eligible Maryland beneficiaries, delivering most of that benefit through managed care organizations with a remaining fee-for-service population. The most common Maryland Medicaid denials seen in Columbia are prior authorization missing or expired, plan-of-record mismatch (patient assigned to different MCO), medical necessity documentation insufficient, timely filing exceeded, and managed care vs FFS routing errors. Because each MCO credentials providers separately and enrollment runs 60-120 days from clean application, confirming plan assignment and credentialing status before the first Columbia visit is decisive for clean first-pass payment. Across Columbia's 20 organizations, even a few percentage points of MCO-routing error compounds into material rework.

In Columbia these are where ABA billing margin is won or lost, so clean documentation, accurate plan assignment, and tight authorization tracking pay back fastest for the city's 20 ABA provider organizations.
