Wiki how to bill for procedure 56420 for a Medicare patient

[crevoet]

Medicare denied claim for 56420 done bilaterally with modifier 50 on the second line. Any help with which modifier to use would be deeply appreciated.

I am pretty sure that you would only list the procedure once with a modifier 50 attached, 56420-50.

From the sound of your note, you listed it as 56420 and 56420-50, is this how you listed it?

Let me know. Not sure about this.

1 line, 1 unit, mod 50, double the charge. 2 lines will cause a denial.
