For the most part, access to your medical records is limited to only those who need access to provide care or to provide payment. If you are over 18 years of age, your parents should no longer have access without your permission. Your spouse or a close relative may have access if you are incapacitated. If you want to assign someone to manage your health care choices if you become unable, you can use a Health Care Power of Attorney document to appoint a health care proxy.
