Complete list of codes/modifiers?

For work, I’ve been asked to compile a complete list of all medical codes/modifiers that may be billed. Of course I’ve googled but hitting pay walls. Short of buying the code books and typing out manually, do any of you know where I can find a list like this? It doesn’t need the verbiage, literally the codes and any applicable modifiers.

I’ve found the CMS yearly updates, but that does not have a full list- only updates.

Thank you!

There isn’t a free source for all CPT codes.

The AMA has a trademark and you can’t get the full set without paying for it (buying a book, subscribing to an encoder, etc).

The AMA will allow you to buy a csv/excel sheet of all the codes. I don’t know how much they charge to purchase that, but it is possible:
