Commercial coverage in Georgia concentrates around a small number of carriers. Anthem Blue Cross Blue Shield of Georgia carries the largest share of the commercial market, so its medical policy and prior-authorization requirements touch a disproportionate share of any practice's claims. Kaiser Permanente runs a closed-panel model in metro Atlanta that pays and processes claims differently from an open-network plan, and UnitedHealthcare, Aetna, Cigna, and Ambetter round out the rest of the commercial mix.
Georgia Medicaid is administered by the Department of Community Health and covers roughly 1.87 million residents, most of them through managed care rather than fee-for-service. Four plans — CareSource, Humana, Molina, and UnitedHealthcare — are positioned to take over that managed-care program from the carriers holding it today. Only one of the four is an incumbent, which means new provider files, new payer IDs, and new authorization rules for most of the state's Medicaid population.
