Amerigroup is a managed care organization focused on Medicaid and Medicare populations, operating as a subsidiary of Elevance Health (formerly Anthem). Amerigroup serves approximately 2 million members across 15 states, primarily through state Medicaid managed care contracts. For providers serving low-income and underserved communities, Amerigroup enrollment is an important pathway to serving this population.
As an Elevance Health subsidiary, Amerigroup's credentialing leverages the parent company's infrastructure and CAQH integration. Providers already enrolled with Anthem's commercial plans may find Amerigroup credentialing comparatively straightforward, though separate applications are still required for each subsidiary's network.
Amerigroup's primary focus on Medicaid means its reimbursement rates reflect Medicaid fee schedules, which vary significantly by state. Providers should evaluate Amerigroup enrollment in the context of their overall Medicaid payer mix strategy and the specific rates in their state. Some states offer managed care rates that are more competitive than traditional fee-for-service Medicaid.
