Hello all. I'm wondering if anyone can help.

I'm auditing an outpatient UB that has 96365 on 10/9/18 and 96367 on 10/10/18. I'm new to Outpatient coding and was wondering if billing these on different dates of service is allowed. The itemized bill does not have times or anything like that attached. If it is or is not allowed, can you please let me know what source you used and possibly the URL? I have to be able to defend my audits.

Thanks!
Yvonne
