Hi Dr. O!
Great question. Yes it is recommended that you register for a personal NPI if you do not already have one, as insurers prefer the use of your personal NPI to indicate the "rendering provider" with an NPI rather than a social security number.
You can search to see if you already have a personal NPI at the NPI registry search using your first name, last name, and state if necessary:

You of course can use your corporate NPI for your billing information in Box 33 of the CMS 1500 claim form.
Hope this helps, please let us know if you have any further questions!
