Join the IEFMC Network

Membership in the IEFMC network brings many benefits to physicians and other healthcare providers. Our no-risk, fee-for-service contracts offer our members reimbursement rates that are comparable to Medicare's. Also, because of our affiliation with the California Foundation for Medical Care, our members belong to one of the largest PPOs in California. The combined IEFMC/CFMC network features a large patient base and a variety of payers. All medical specialties are represented in the network, with no restrictions on referrals.

Because IEFMC is a nonprofit entity governed by physicians, the network is designed to support our members rather than to squeeze them for profits. All members are automatically enrolled in our PPO network. We also offer an exclusive provider organization (EPO) network and a worker’s compensation organization (WCO) network. See the types of networks section below for more details.

Physicians and other providers in the IEFMC service area are welcome to apply for membership at any time. Our staff handles the entire credentialing process, and most applications can be approved within a matter of weeks.

Types of Networks

IEFMC administers three types of provider networks: a preferred provider organization (PPO), an exclusive provider organization (EPO), and a worker’s compensation organization (WCO).

Our PPO is part of the largest provider network in California and is used by a long list of health plans and self-insured employers. The EPO is a smaller network in which providers agree to greater discounts and expanded utilization review. The WCO is for worker’s compensation cases. All our providers are automatically enrolled in the PPO network and have the option of joining the EPO and WCO networks.

Providers in the networks agree to accept IEFMC’s fee schedule and to have their medical services reviewed by peers in their field. Providers also agree to bill on behalf of the patient and to accept the IEFMC allowable as payment in full, less the patient’s responsibility for copayments, deductible, or coinsurance. There are no restrictions on in-network referrals.

Apply for Membership

Physicians and other health care providers in the following California counties are eligible for membership in IEFMC: Riverside and San Bernardino. Providers in other California counties can join similar networks run by their local medical foundations. For a complete list of foundations, see our IEFMC Service Area map. The application process is straightforward. After you contact us, we will send you an application form, which you can return via fax or mail. Our staff handles all credentialing, saving you the trouble of credentialing with multiple payers. Completed applications are submitted to our physician-led board of trustees for final approval. The entire process can usually be completed in a matter of weeks. To apply for membership in the IEFMC Network, click the button above to download an application form.
