Research steps
- Confirm that the employer plan includes an out-of-network benefit and check its filing limit. NOT PUBLISHED: CareFirst Administrators does not publish a universal deadline because it administers employer plans. https://www.carefirst.com/cfa/members/resources-for-members/forms.html
- Prepare the MEDICAL CLAIM FORM and a legible itemized bill. The public form does not enumerate the bill fields. https://www.carefirst.com/cfa/docs/medical-claim-form.pdf
- Have the employee and patient sign the authorization. Leave the assignment section blank when payment should go to the member. https://www.carefirst.com/cfa/docs/medical-claim-form.pdf
- Log in to the member portal, select Submit an Out-of-Network Claim, and follow the instructions. https://www.carefirst.com/cfa/members/faqs/faqs.html
- NOT PUBLISHED: accepted file types, per-file size, maximum file count, single versus separate files, and submission confirmation. The signed-in controls are UNREADABLE. https://www.carefirst.com/cfa/members/faqs/faqs.html
