Question about how to handle billing when a patient returns due to a leaking chemo pump. The patient had an Adrucil pump started on 05/11, but called on 05/13 reporting it leaked overnight. THen came back in to complete the remaining 25mL of the infusion with a new CADD pump after confirming the original was visibly soiled and likely leaked at the OnGuard adapter connection. The pump was then replaced and the infusion restarted, with plans for disconnection at another facility. We billed them 95,416 on 05/11, but there was a confusion about whether we can bill it again on 05/13. Since this wasnt a new infusion, just finishing the original dose, I don't believe 95,416 or 95,521 are appropriatee. The only possible billing I see is maybe an E/M code, but Im not too sure since the visit was handled entirely by the infusion RN and not the oncology provider. Urgent help please.
