That will depend upon what type of health insurance you have and what your coverage status is. I will presume that you are a young person who has taken advantage of the changing age definition for dependent coverage under the Affordable Care Act (ObamaCare) that allows dependent children to stay on their parent's health insurance until they turn 26. In that case, once you turn 26 you are no longer eligible to be covered as a dependent under your parent's policy. This means you will have to take out health insurance coverage if it is available through your place of employment, purchase your own individual health insurance policy, or enroll in a government based health plan such as Medicaid if you meet the low income requirements for such a program.
If you are already enrolled in your employer's group health insurance plan or have already obtained individual health insurance then the fact that you are turning 26 will have no impact on your eligibility for health insurance coverage under that policy.

What happens to your health insurance when you turn 26? Well, if you are the primary insured as a policy holder or employee on a benefit plan, absolutely nothing happens. If you are a dependent on your parents coverage, you will now have to seek your own coverage in the marketplace. You are given an open window to move to your own plan.

If you are on a group policy from your employment then nothing happens to it until you separate from your employer. But, if you are your parent's policy then at the time you turn 26 you must get a policy of your own. This is considered a special event and you don't have to wait until Obamacare open enrollment.
If you are already enrolled in your employer's group health insurance plan or have already obtained individual health insurance then the fact that you are turning 26 will have no impact on your eligibility for health insurance coverage under that policy.
