How Long Does Health Insurance Last After Quitting Your Job? 
Your employer health insurance plan can stop at any time after you quit your job . It depends on how the plan summary is written . Some plan benefits cease the last day you work . Others continue through the end of the month and some continue for 30 - 90 days . Check your policy or ask HR how your plan works . If you exercise your COBRA options you can keep your group plan for up to 18 months in most situations .
