Change in Participating Effective Date Policy
Effective April 1, 2008, all physicians and other health care professionals must be credentialed before they can participate in a Regence provider network.

Beginning April 1, 2008, the following policy will apply to all participating providers:

• New provider agreements will have an effective date of the first day of the month in which the provider was credentialed (e.g., if credentialing was approved on June 14, the agreement will be effective on June 1).
• If Regence does not receive a signed agreement in the same month as credentialing is completed, the agreement effective date will be the first of the month in which credentialing is approved or the signed agreement is received, whichever is later.
• A new provider joining a group or clinic agreement will have an effective date of the first day of the month in which he or she was credentialed (e.g., if credentialing was approved on June 14, the effective date of participation will be June 1).
• If a provider already participating with Regence adds an additional network, the effective date of the new network will be the first day of the month the signed agreement is received.
• Regence will no longer establish retroactive agreement effective dates.
• Claims submitted to Regence for dates of service prior to the provider’s effective date will be processed as out-of-network.
