Wiki E/M submitted to payer on 9/30, labs submitted for payment on 10/2:

[Bjornson]

In our clinic we are wondering about the following scenario. If one of our providers bills for an office visit on 9/30 but the labs for that visit are not performed and submitted until 10/2 should the labs be submitted with ICD-9 diagnosis codes or ICD-10 diagnosis codes? Thank you, Nan

If the date of service of the labs is in October, then bill it with ICD-10.
It's date of service, not date of submission.
