The Health Insurance Portability and Accountability Act (HIPAA) of 199
6 (PL. 104-191) brings the federal government fully into insurance reg
ulation for the first time. Despite the Republican majority's rhetoric
about stale control, election-year politics trumped federalism. HIPAA
's immediate impact on coverage may be modest, but its ultimate signif
icance is great because it creates a template for more far-reaching fe
deral involvement in regulating insurance. HIPAA amends the Employee R
etirement Income Security Act (ERISA), the Public Health Service Act,
and the Internal Revenue Code, creating a complicated structure dictat
ed by efforts to avoid an unfunded mandate. The history of insurance r
egulation and the activity surrounding the enactment of P.L. 104-191 s
uggest that HIPAA continues an incremental process of transition betwe
en stale insurance regulation and federal oversight driven by recent a
nd accelerating changes in the structure of the health-care marketplac
