Patient presents in the OP hospital with intractable pain/muscle spasms. Has a diagnosis of Ehlers-Danlos Syndrome. They are frequently treated in the OP hospital for 2 days with the PCA pump. Should a continuous IV infusion, 96365-96366, be billed or would this be a situation when a C8957, IV infusion for therapy/diagnosis;initiation of prolonged infusion (>8 hours), requiring use of portable or implantable pump, and have one charge? The one other option would be to charge a push each time they load the cartridge but I don't believe that is correct at all. We are leaning towards the 96365-96366 but with the Medicare audits, we really want to make sure we are correct. Any suggestions? Thanks!!
