Billing Category III Cpt code (for Morph device)

Good morning again (just posted a similar question on a different device) I was approached about an implantable device for pain control: The Morph Device (https://themorphdevice.com/) The billable codes theyre saying are 0720T and 64553. Now 64553 is payable by medicare (this device is not payable to podiatrists, but it is to NPs to which I employ). The 0720T code don't show in the Medicare fee schedule, neither code is linked to any LCD, but the rep provided EOBs showing payments. Which I know isnt guarantee of being a legitimate. I'd like to be buy the book if possible. While avoiding future clawbacks as well. 1-How does one look at the documentation or program requirements to properly document these codes? 2-Any other advice? Thank you! Luke
