ExplanationOfBenefit
Explanation of Benefit (EOB) is a FHIR resource ( JSON example) that contains a statement from a health insurance plan describing what costs will be covered for medical care received (e.g., a medical procedure or a prescription) by a covered person.
There are three main types of EOBs:
- Institutional - A claim for inpatient or outpatient institutional care. Based on UB-04 / CMS-1450. In Medicare, corresponds to Part A claims.
- Professional - A claim for physician or other professional care outside of an institution. Based on CMS-1500. In Medicare, corresponds to Part B claims.
- Pharmacy - A claim for a prescription or other pharmacy product. Based on NCPDP standards.
A history of EOBs can aid in workflows where the financial aspects of care are important, such as recommending the best health insurance plans during enrollment periods or calculating the patient's liability for a newly billed service.
As a core financial resource, almost all payers make this available and is one of the most important resources Flexpa uniquely provides access to today.

#Profiles
EOBs are profiled in the CARIN Blue Button 2.0 Implementation Guide to provide a standardized structure for EOBs. The following profiles are available in Flexpa:
