All healthcare providers, payers, and facilities use CPT® codes. There are certain codes that can only be billed by certain specialists. And each code has its own rule on how it can be used. A provider does not need to be enrolled in Medicare to report and get paid when billing CPT codes. Now, whether or not they will be reimbursed is another issue, I would suggest to you to read guidelines, LCD’s and articles pertaining to the codes in question. Even if a provider is not a Medicare provider there are a lot of payers that follow Medicare’s guidelines. If you are asking due to a matter of licensure, it will depend on the scope of practice under the license and the payer.
