A prior authorization, or pre-certification, is a review and assessment of planned services that helps to distinguish the medical necessity and appropriateness to utilize medical costs properly and ethically. Prior authorizations are not a guarantee of payment or benefits.

How do I submit an authorization?

Prior authorization requests should be submitted electronically using the CareFirst BlueCross BlueShield Provider Portal (CareFirst Direct).

Clinical Guidelines

Our medical prior authorization system automatically triggers MCG guidelines and requires providers to complete additional information depending on the combination of the diagnosis and procedure codes. Maryland Medicaid inpatient reviews leverage MCG's Inpatient Care Guidelines. Access detailed information on MCG's Care Guidelines.

What services require a prior authorization?


Medical Drug Prior Authorizations

CareFirst CHPMD will require prior authorization on certain medical drugs. Prescribers must complete the entirety of the medical injection preauthorization request form with supporting medical documentation and send to CareFirst CHPMD to render medical necessity coverage determination. Failure to do so will result in non-payment. You will not be reimbursed without an approved prior authorization.
