Question: Are we allowed to charge the patient for extra catheter supplies that we send the patient home with? Nevada Subscriber Answer: According to the Medicare Learning Network (MLN) Fact Sheet, “Medicare makes a single payment to ASCs for covered surgical procedures, including ASC facility services furnished in connection with the covered procedure.” Included in this payment are the following: In this example, you may consider the catheter equipment as surgical “supplies” and therefore include them in the global ambulatory surgery center (ASC) payment. Note: In a freestanding ASC, when billing on a CMS-1500, you should not typically charge the patient for any services the physician renders outside of the surgical procedure. Ina hospital-based ASC, which you typically bill on the UB-04, non-routine sterile surgical supplies may be included in the surgical procedure or separately reported under revenue code 0272.
