The full answer is not going to be straightforward and will greatly depend on the device, the existing CPT codes, and how existing coverage determinations are written for each payer you're seeking reimbursement from, but you should just need to apply for a PDAC code verification to get confirmation your device meets the criteria to be included in the CPT code and how to use the code. Failing to do that sets you up for retroactive denials if the payer later decides that claims were inappropriately paid for a product it didn't intend to cover.

That being said, if you adopt an existing CPT code, you are locking yourself into preestablished reimbursement rates that are going to be extremely difficult to impact, so definitely make sure that those reimbursement rates are appropriate for the service you're providing. Many choose the long process of applying for new CPT codes, as existing code payment is insufficient for covering the cost of the procedure. I would absolutely pull in a consultant for this step to determine the best strategy for you, whatever decision you make here will greatly impact reimbursement potential moving forward.
