Post-operative wound care

We have a physician who recently started seeing patients at a Wound Care Center. We are questioning whether we can bill for this or not. The majority of these patients are in their post-op 90 day global period and are coming to the wound center for dressing changes. He wants to bill an e/m visit.

Has anyone dealt with this situation before? Any resources that you could share?

I'm looking everywhere, but all I find is in regards to wound treatment. Sometimes he performs debridement, but he never performs treatment that require cpt codes 95797-97610.

Any help would be appreciated.

Thanks!
