BILATERAL PROCEDURE: 50 MODIFIER

Date: Jul 7, 2021

Question:

Some of my claims came back denied for -50 modifier. Per CPT Codebook, if bilateral procedures are performed at the same session, should be appended 50 modifier. The insurance paid for one and denied the other. Am I using the wrong modifier? Or should I just billed two units?

ex: 34713

34713-50

37609

37609-50
