We billed primary code (99291-25) with add-on code (99292) along with 36620. The claim denied. Stating that procedure code 99292 needed an add-on code.
Now, first I wanted to append a 59 modifier to procedure code 36620. The insurance company is stating that a modifier needed to be appended to procedure 99292. It was my understanding that you never add a modifier to an add-on (according to the CPT book).
Can someone please help clear this up for me? I would greatly appreciate it.
