If You Can't Reach Them

The number doesn't work, or it's the wrong place

Try another office above. See this doctor's own record in the NPI Registry. Then tell us. We check it against the source. We don't ask who you are, and we don't store your IP address.

You reached a hospital or a main line

Ask for Dr. Hyer's office or the cardiology department. If they can't find the doctor, tell us.

They aren't taking new patients or your plan

That's common, and only the office can say. See other cardiologists in Westerville, your plan's own directory, Medicare.gov Care Compare or call 1-800-MEDICARE. Read how to check for new patients.

You can't get through and it's urgent

In an emergency call 911. In a mental health crisis call or text 988.
