What to do

02If not yet adopted, billing and front-desk staff should log into NaviNet, navigate to Horizon Plan Central, select Eligibility and Benefits, and use the Cost Share Estimator to check member eligibility, coverage, estimated out-of-pocket costs, and prior authorization requirements before calling Provider Services.
03For member IDs without '3HZN', continue calling the Provider Services number on the member's ID card.
