Maryland Medicaid and Annapolis routing.
Maryland Medical Assistance Program covers ambulatory surgery 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 Annapolis 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 Annapolis visit is decisive for clean first-pass payment. Across Annapolis's 27 organizations, even a few percentage points of MCO-routing error compounds into material rework.
