The prior authorization lookup tool attempts to provide the most current information for the provider. Please note that this information may be subject to change, and a prior authorization is NOT a guarantee of payment. Payment is dependent on a number of factors, including but not limited to member eligibility on the date of service, coverage limitations and exclusions, provider contracts, and correct coding and billing for the services at issue. AmeriHealth Caritas DC reserves the right to adjust any payment made following a review of the medical records and determination of medical necessity for the services rendered. All non-participating providers must submit requests for prior authorization, except as may be required by law. For additional details, or if you are uncertain that prior authorization is needed, please see the provider manual on the AmeriHealth Caritas DC website.
