According to a crosswalk I located, there are literally like 20 NDC codes listed. I also compared the new vials to the old ones and the NDC codes are definitely different. Both codes are now converting to the one J1010 but J1030 and J1040 had different NDC codes so this is very confusing to me as well. In addition, is this going to affect billing wastage. In a Medicare previous example when the JZ modifier was introduced, it indicated that J1030 would not have wastage because they are intended for a one time use vial. I do have that in writing from CMS website. So now with this new code, is there going to be wastage to be considered if we only use 30 mg of a 40 mg vial. I am assuming not because it is still considered to be a single use vial. This is all too confusing. I have received denials this week from literally every payer for the new code that I had no idea was coming
