Under what circumstances would I not be able to see my medical records?

The Health Insurance Portability and Accountability Act of 1996 (HIPAA) Privacy Rule gives you the right to inspect, review and receive a copy of your health and billing records that are held by health plans and healthcare providers covered under HIPAA. In a few special cases, you may not be able to get all of your information. For example, your doctor may decide that something in your file could physically endanger you or someone else and may not have to give this information to you.
