When You Quit A Job When Does Health Insurance End? 
Depending on the plan design and how your employer approaches it , either the last day of work or the last day of the month . After that , if your employer has 20 people at work on any given day , you should be offered COBRA continuation coverage . The 20 headcount for COBRA continuation can inlcude part time employees that are not part of the health plan . If your health plan was with a company of less than 20 active employees on any given day , you may still get some extended coverage . it 's going to depend on the state and plan design . In my state some insurers offer 3 months extended coverage for people who are n't COBRA eligible because of the size of the group .
