This document contains interim rules governing access, portability and renewability requirements for group health plans and issuers of health insurance coverage offered in connection with a group health plan. The rules contained in this document implement changes made to certain provisions of the Internal Revenue Code of 1986 (Code), the Employee Retirement Income Security Act of 1974 (ERISA), and the Public Health Service Act (PHS Act) enacted as part of the Health Insurance Portability and Accountability Act of 1996 (HIPAA). Interested persons are invited to submit comments on the interim rules for consideration by the Department of Health and Human Services, the Department of Labor, and the Department of the Treasury (Departments) in developing final rules.
