Pricing Model
EnterpriseFDA-cleared AI clinical care coordination for neurovascular and cardiology — Institutional hospital and health system annual contracts
EnterpriseAbridge does not publish pricing and sells exclusively through enterprise contracts with health systems and hospital groups; there is no self-serve signup or individual-clinician plan. Third-party market analyses and reseller estimates place costs at roughly $200-$800+ per provider per month depending on integration depth (Epic, Oracle Health, or athenahealth), contract scale, and support level, with some estimates for full enterprise rollouts running $600-$1,200+ per provider per month. Implementation typically includes a multi-week to multi-month pilot and IT integration phase before system-wide deployment.
