We've recently begun to receive Medicare denials on claims submitted by PAs and NPs for CPT 61108. The denial states “This provider type/provider specialty may not bill this service”. This has never been an issue until this calendar year. We changed MACs from Cahaba to Palmetto effective Feb 26 but some dates of service are prior to that change. I've not been able to find anything on this and was curious if anyone else was having this issue.
