Payer Overview
Medical Associates GRP is the #189 largest US A&H payer by reported premium, operating with a US premium of $130.31M and a US market share of 0.01%. The company reports a presence across 3 states, and serves an estimated total membership of 20K, operating through 2 affiliated subsidiaries. The payer does not hold a #1 position in any state.
