The Medicare Advantage (MA) landscape in the United States is sustained by an intricate network of healthcare Providers, Beneficiaries, and Payors. Payors, private health insurance organizations which provide health coverage for MA beneficiaries, cleverly steer the course of care management, wisely balancing the demands of maintaining care quality, managing costs, and maintaining appeal in the market.

This article underscores the fluidity and fierce competition among Payors within the MA market. Despite the fluctuating dynamics, this piece continues to cover the facts on the landscape of Payors with different sub-entities and the positioning of the same in terms of enrollment.

In the Medicare Advantage market, roughly 300 Parent Organizations (POs) are currently providing individual and group Medicare Advantage plans nationwide in 2023, marking a slight decrease from 307 POs in the previous year. Here is a breakdown of the number of POs providing different types of plans:

Trinity and Centene Corporation (Centene) also have a notable presence, each containing 13 MOs. Across all SNP types, Elevance surpasses others with the highest number of subsidiary entities. The sole exception to this is in the I-SNP category, where the PO Mark T. Mitchell takes the lead.
