I was asked by a payer to review a claim submitted by a hospital. The hospital billed ICD 10 PCS code ODH673Z. This code is listed as an operating room procedure in CMS Appendix E, however, it was performed at the bedside and there is no operative report. I am assuming that an "operating room procedure" must be performed in the operating room but I cannot find a guideline that states this. Can someone please offer some guidance on procedures performed at the bedside that are listed as operating room procedures in Appendix E. Thanks
