Each carries its own prior authorization workflow and medical necessity criteria, so the Denver payer mix drives the local denial profile.

Colorado Medicaid and Denver routing.
Health First Colorado covers ABA billing for eligible Colorado beneficiaries, delivering most of that benefit through managed care organizations with a remaining fee-for-service population. The most common Colorado Medicaid denials seen in Denver 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 Denver visit is decisive for clean first-pass payment. Across Denver's 96 organizations, even a few percentage points of MCO-routing error compounds into material rework.

Because Denver carries 19.5 percent of Colorado's ABA provider organizations and ranks 2 of 3 in the state, its denial exposure scales with that footprint. In Denver 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 96 ABA provider organizations.
