The Patient-Centered Outcomes Research Institute (PCORI) was created by the Affordable Care Act to promote research that compares the effectiveness of medical treatments. PCORI is funded by an annual fee paid by health insurers and sponsors of self-insured health plans. Plan sponsors must calculate the average number of lives covered and pay the PCORI fee of $2 per life for plan years ending before October 1, 2014 or $2.08 per life after on Form 720 by July 31 of the year following the plan year. Responsibility for paying the fee lies with the health insurer for fully insured plans and the plan sponsor for self-insured plans.
