Yes — Oscar and Ambetter both participate in the Seminole County small group market and typically offer Bronze and Silver HMO premiums 10–18% below Florida Blue for the same tier. For a 10-person Seminole business, switching from Florida Blue Silver HMO to Oscar or Ambetter Silver HMO can save $3,500–$7,000/year. The trade-off is a narrower provider network — both Oscar and Ambetter have more limited specialist networks than Florida Blue in Seminole County. For professional services firms where employees expect access to Lake Mary and Altamonte Springs specialists, a broker comparison of network adequacy alongside premium is essential.
