Upon approval of enrollment (the provider has met all necessary requirements); the enrollment date of the provider’s effective date will retroactively begin 90 days prior to the date of receipt of the application. However, depending on the provider’s type/ specialty, if the provider is required to sign a contractual agreement in addition to the provider enrollment agreement, the enrollment date is the effective date of the contract. Note: Medicaid will not pay for claims prior to an enrollment effective date or before the provider’s licensure/certification date.
