Final answer:
When coding for bladder tumor removal during cystourethroscopy, two separate CPT codes should be used with the modifier -59 to indicate separate locations.
Step-by-step explanation:
Bladder Tumors and Coding
When coding for bladder tumor removal during cystourethroscopy, the coding rule to apply is to use two separate CPT codes.
Each tumor's size and location should be separately coded, along with the appropriate modifier, -59, to indicate that the two lesions are in separate locations. In this case, you would code for the 1.5-cm bladder tumor on the anterior wall and the 0.75-cm tumor on the lateral wall.
Thus, two CPT codes should be used with the modifier -59.
