Notice 2019-45 responds to President Trump’s recent Executive Order that directed the Secretary of Treasury to issue guidance to expand the ability of patients to select HDHPs that: (i) can be used alongside a health savings account and (ii) cover low-cost preventive care, before the deductible, that helps to maintain health status for individuals with chronic conditions.
In prior guidance, under Notice 2004-23, the Treasury Department and the IRS had stated that “preventive care” does not generally include any service or benefit intended to treat an existing illness, injury, or condition. However, in this new notice, the Treasury Department and the IRS acknowledge that cost barriers to care have resulted in some individuals with chronic conditions failing to seek effective and necessary care that would prevent the exacerbation of that condition. They also note that failure to address these chronic conditions has been demonstrated to lead to consequences such as amputation, blindness, heart attacks and strokes that require considerably more extensive medical intervention.
As a result, the Treasury Department and the IRS, in consultation with the Department of Health and Human Services, have detailed specific medical care services received and items purchased that may now be classified as “preventive care” for purposes of HDHPs if prescribed to treat an individual diagnosed with the associated chronic condition, as specified below.

The specified services and items listed above are only treated as preventive care when they have been prescribed (i) to treat an individual diagnosed with the associated chronic condition specified above, and (ii) for the purpose of preventing the exacerbation of the chronic condition or the development of a secondary condition. Services or items that are not listed in Notice 2019-45 that are for secondary conditions or complications are not treated as preventive care for purposes of the HDHP rules.
Notice 2019-45 does not change the services and items that are considered preventive care for purposes of the provisions of the Patient Protection and Affordable Care Act requiring non-grandfathered group health plans to provide benefits for certain preventive health services without imposing cost-sharing requirements.
Considerations for Plan Sponsors
Plan sponsors that maintain HDHPs may wish to review their existing policies and practices with respect to those plans to ensure proper administration given the new guidance.
