All EOB instances should be from one of the four non-abstract EOB profiles defined in this Implementation Guide: Inpatient, Outpatient, Pharmacy, and Professional/NonClinician CARIN BB EOB Inpatient Facility:  The profile is used for Explanation of Benefits (EOBs) based on claims submitted by clinics, hospitals, skilled nursing facilities and other institutions for inpatient services, which may include the use of equipment and supplies, laboratory services, radiology services and other charges.

CARIN BB EOB Professional and NonClinician:  This profile is used for Explanation of Benefits (EOBs) based on claims submitted by physicians, suppliers and other non-institutional providers for professional services.
