When Does Health Insurance End When Leaving A Job? 
If you leave your job or are terminated your health insurance usually ends at the end of the month you left your job . At that time you would be eligible for COBRA continuation coverage for 18 months or you could purchase indivdiual health insurance . COBRA used to be the best option if you had a pre-exisitng condition but under the Affordable Care Act , commonly known as Obamacare , you can purchase individual coverage with no issues . You have to prove that you have a qualifying event under the IRS code which is a letter of Creditable Coverage from your former health insurance company or employer .
