Medical Care Power of Attorney vs. HIPAA Waiver: What’s the Difference?

When planning for your health care, it’s important to understand the tools available to ensure your wishes are honored and your loved ones can act on your behalf. Two common documents that come up in this process are the Medical Care Power of Attorney (also called a Health Care Power of Attorney) and the HIPAA Waiver. While they may sound similar, they serve very different—but equally important—purposes.

Here’s a breakdown of what each document does and why you may need both.

1. What is a Medical Care Power of Attorney?

A Medical Care Power of Attorney (HCPOA) is a legal document that allows you to appoint someone you trust to make medical decisions for you if you are unable to make them yourself. This designated person—called your agent or proxy—can:

  • Discuss treatment options with your doctors
  • Approve or decline certain medical procedures
  • Make decisions about long-term care and end-of-life treatment

This document only goes into effect when you’re incapacitated or otherwise unable to communicate your wishes.

2. What is a HIPAA Waiver?

A HIPAA Waiver (also known as a HIPAA Authorization) is a document that allows your health care providers to share your private medical information with specific individuals you name. Without this authorization, your family and loved ones could be denied access to your medical status or history—even in emergencies.

A HIPAA Waiver does not grant decision-making authority; it only grants the right to access medical information.

4. Why You Likely Need Both

Having both documents in place creates a complete health care plan. Here’s why:

  • Your health care agent may need access to your records to make informed decisions.
  • You may want other family members informed, even if they aren’t making decisions.
  • Hospitals and doctors often require both documents to fully communicate with your support network.
