I just finished my CPC Coding/Billing course, and am currently studying for the big exam.

I had an assignment that I got an A on (A for effort), but my instructor never got back to me (I emailed her twice) of what the correct code was for the following:

Right ureteroscopy, retrograde pyelogram, and right ureteral biopsy
Dx: Hematuria

I was told there should only be one code, so I coded the first procedure. However, after reading the guidelines, I put that I would also code the biopsy. I also stated that because there can only be one code, I chose 0TJ98ZZ.

My instructor wrote that she understood my logic (I won’t paste my whole reasoning here). But: what is the correct procedue to code, and why? Thank you!
