Insurers Administrative Corporation (IAC) is a Third Party Administrator for a number of insurance companies and self-funded corporations. We utilize many different PPO's throughout the country and to determine the method of submitting electronic claims to IAC you will need to know the PPO (if any) that is shown on the front of the member's ID card.

If the front of the ID card shows PHCS, CCN, First Health, Accountable Health Plans, ppoNEXT, Ohio Health Choice, InterWest or Multiplan as the member's PPO (the logo will be in the upper middle of the card), then you may submit your electronic claims to either WebMD/Envoy or ENS or THIN. For WebMD/Envoy our payor id is 86304.  For ENS and THIN, our payor id is IAC01. If you cannot have your electronic claims reach any of these 3 networks, please continue to send paper claims to the address shown on the card : IAC, PO Box 828, Park Ridge, IL 60068-0828.

For all other PPO's, if you are a participating provider in that PPO shown on the front of the card, you should follow the instructions you have received from that PPO to submit electronic claims to them. Your PPO will then forward the claims to IAC.

If there is no PPO Network logo on the front of the card OR if you are not a participating provider in the network shown on the front of the card, you may submit your electronic claims to WebMD/Envoy with our payor id of 86304 or to either ENS or THIN with our payor id of IAC01.

If you are a dental provider, please continue to send paper claims to the address on the card. We are not yet ready to accept electronic dental claims.

Should you require further assistance, please call IAC at 1-602-906-6251.
