29 U.S. Code § 1191 - Preemption; State flexibility; construction
Subject to paragraph (2) and except as provided in subsection (b), this part shall not be construed to supersede any provision of State law which establishes, implements, or continues in effect any standard or requirement solely relating to health insurance issuers in connection with group health insurance coverage except to the extent that such standard or requirement prevents the application of a requirement of this part.
Nothing in this part shall be construed to affect or modify the provisions of section 1144 of this title with respect to group health plans.
Subject to paragraph (2), the provisions of this part relating to health insurance coverage offered by a health insurance issuer supersede any provision of State law which establishes, implements, or continues in effect a standard or requirement applicable to imposition of a preexisting condition exclusion specifically governed by section 1181 of this title which differs from the standards or requirements specified in such section.
Except as provided in section 1185 of this title, nothing in this part shall be construed as requiring a group health plan or health insurance coverage to provide specific benefits under the terms of such plan or coverage.
The term “State law” includes all laws, decisions, rules, regulations, or other State action having the effect of law, of any State. A law of the United States applicable only to the District of Columbia shall be treated as a State law rather than a law of the United States.
