Peds here. We do lots of immunizations. In the past week UHC has started to reject claims with the vaccines/injection code 90460 and referencing smart edit P4999S45DN. I reviewed the edit and did not see anything about 90460. I Know they Its NOT an add-on code, but I've seen payers write wacky edits. I did see that an Add-on Code policy was updated on 6.28.21 (policy # 2021R0071A) stemming from an CMS update, but again nothing about that code in particular. On a somewhat good note, while they rejected in my clearinghouse they were actually accepted by the UHC and they paid the WCC, the imms, and even the 90461 (the true add on code) but denied the 90460. Was curious if anyone else is running into this issue?
