I just started work in a family practice clinic and noticed they are having Medicare pts sign ABN for PT/INR, but are using the QW modifier for CLIA waived testing with the dx of HX of DVT and long term use of anti coag.....can someone please tell me if this is correct? It seems like overkill to have them sign the waiver if Medicare covers it under this DX.
