I'm sure you have all heard there is a BCG shortage. The latest recommendation for subsequent treatments is to use 1/3 dosage and treat 3 patients from one vial. We have been searching for proper coding since 90586 and J9031 just say each use and it is typically a one dose vial. We have reached out to Medicare, they are researching, have contacted AUA and await their response. Any suggestions of modifier? I have not found anything that looks appropriate for the drug. We don't want to be fraudulent so seeking advice.
