Question: The urologist performed what she documented as “laparoscopic right renal hilar skeletonization.” This is a new procedure for me; what is the best code for it? Minnesota Subscriber Answer: The current CPT® manual does not include a code appropriate for renal hilar skeletonization. Your best option is to report unlisted code 50549 (Unlisted laparoscopy procedure, renal). Include a cover letter with your claim, explaining why you are reporting an unlisted procedure code. Also include clear documentation (in simple, easily understood terms) of exactly what the physician did and why, indicating clearly the diagnosis for the renal hilar skeletonization. Benchmark code 64722 (Decompression; unspecified nerve(s) (specify)) for comparison purposes when suggesting an appropriate payment to the insurer.
