Mr. Knowitall
Most people have changes in their needs and desires over the course of 20+ years. Odds are the requirements of your undisclosed state haven't changed. I also won't promise you that a recipient won't look askance at a 20+-year-old power of attorney.
You would be better off attaching an addendum with the current address, or drafting and executing a new document with a current address. Making changes to a notarized document could create significant issues for somebody trying to rely upon the document.
If your present healthcare proxy is not HIPAA-complaint, you can consider either drafting a new one that is HIPAA complaint (you can probably find a free form for your undisclosed states - many hospitals distribute them and some states have statutory forms), or executing an appropriate additional document to address the issue.
We ask for a reason.
