Healthcare Benefit Enrollment and Maintenance 834 Transaction

The EDI 834 transaction is a standard format used in Healthcare and Insurance Electronic Data Interchange (EDI) for the exchange of information related to the enrollment and maintenance of benefit plans, primarily in the context of healthcare benefits. Let’s take a look at some of its key components:


The EDI 834 transaction is used to transmit enrollment and maintenance information from employers, insurance companies, or benefit administrators to insurance carriers, third-party administrators, or other entities responsible for administering benefit plans. It facilitates the electronic exchange of data related to the enrollment of individuals in benefit plans, such as health insurance, dental insurance, vision insurance, and other types of benefits.

Data Elements

The EDI 834 transaction contains various data elements that convey information about the enrollment and maintenance of benefit plans. These data elements include demographic information about covered individuals (such as name, address, date of birth, and Social Security number), details of the benefit plan being enrolled in (such as plan type, coverage levels, effective dates), and other relevant information necessary for administering the benefits.


The EDI 834 transaction supports various types of enrollment and maintenance transactions, including initial enrollments, changes in coverage, terminations, reinstatements, and other updates to benefit plan information.


The EDI 834 transaction format is governed by the Accredited Standards Committee (ASC) X12 standards, which define the structure and syntax for EDI transactions in various industries, including healthcare. Compliance with these standards ensures that the data exchanged between different entities is consistent and interoperable.
