SECTION 2. BACKGROUND
Internal Revenue Bulletin 2004-15 · 2026-10-03 edition · updated 2026-10-04 · United States
Section 1201 of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, Pub. L. No. 108–173, added section 223 to the Internal Revenue Code to permit eligible individuals to establish HSAs for taxable years beginning after December 31, 2003. Generally, an “eligible individual” is an individual who is covered by an HDHP and no health plan that is not an HDHP. Revenue Ruling 2004–38, clarifies that an individual who is covered by a health plan that provides prescription drug benefits before the minimum annual deductible of an HDHP has been satisfied, is not an “eligible individual” under section 223(c)(1)(A) and may not make contributions to an HSA. Because of the short period between the enactment of HSAs and the effective date of section 223, many employers and health insurance providers have been unable to
modify the benefits provided under their existing health plans to conform to the statutory requirements for an HDHP. Thus, it is appropriate to provide transition relief to allow individuals to contribute to an HSA who would otherwise qualify as eligible individuals but for coverage by a prescription drug benefit provided under a separate plan or rider that is not an HDHP.
