The IRS guidance on the availability and implementation of the ARPA 100 percent COBRA premium assistance provides some useful guidance on specific scenarios that employers and employees may now be facing. Generally, individuals remain assistance-eligible individuals (AEIs) during eligibility waiting periods if the period overlaps with the subsidy period. For example, the individual will be an AEI during periods outside the open enrollment period for a spouse's employer-sponsored health coverage. Employers who change health plan options must place the AEI in the plan that's most similar to their pre-termination plan, even if it's more expensive (and the 100 percent subsidy will continue to apply). Importantly, employers who are no longer covered by federal COBRA requirements may still be required to advance the subsidy (for example, if the employer terminated employees so that the federal rules no longer apply). If the employer was subject to COBRA when the individual experienced the reduction in hours or involuntary termination, the employer must offer the subsidy.
