you are covered by prescription drug benefits under the Fund and
   you also have "other prescription drug coverage".

"Other prescription drug coverage" means coverage under any insurance arrangement for prescription drug benefits other than coverage under the Fund, including coverage provided by another employer or your spouse's employer. If you and our spouse both have coverage under this Fund through your respective Contributing Employers, you are not eligible for this Program, unless you or your spouse also has "other  prescription drug coverage" (for example, through another employer).
