State-by-State Market Position

Sentara Health Management Group shows a clear regional concentration in the Southeast, with its strongest presence in Virginia and a modest foothold in Florida. The Southeast is the dominant region for this payer, while the Northeast, Midwest, West, and Southwest show no reported presence in the provided data. The payer's top-ranked state is Virginia, which drives the majority of premium and membership.

For multi-state provider groups, the distribution implies that contracting and network development efforts should be weighted toward Virginia to capture the greatest share of encounters and premium. Florida represents an opportunity to expand but on a far smaller scale — roughly $607M in premium versus $6.52B in Virginia — so resource allocation should reflect that disparity.

Estimated Members by State

SENTARA HLTH MGMT GRP's estimated membership is highly concentrated in Virginia, with 999,807 members, accounting for the vast majority of its national insured base. Florida is the next largest state, with an estimated 68,839 members. No other states have reported member estimates, indicating a focused geographic footprint.

This distribution aligns with the payer's market share dominance in Virginia, where it holds a 15.47% share and ranks #2 in the state. In Florida, despite a much lower market share (0.47%), the large population base results in a meaningful member count. For providers, this means that contracting and care delivery strategies should be tailored to the unique needs and competitive dynamics of these two states, with particular emphasis on Virginia as the primary market.
