I’m hoping to get an opinion on the correct coding for this. Physician performed 64483 bilaterally on one level, however, had issues and could not complete the left side. It was billed as 64483-RT, 64483-53-59-LT. Medicare paid the right side, but denied the left as information submitted does not support this many/frequency of services. Documentation was sent, but it still denied.

I thought about changing the left to 64484-53-LT, although the definition of 64484 is for each additional level and this was the same level as the right side. The only other thing I can think of is to bill the bilateral as 64483-53-50, but I wasn’t sure if the completed side would get paid at the full rate if I do this.

Thanks!
