It's OK to Change EVLT Code

Question: Our physician performed anesthesia during endovenous laser treatment (EVLT) on the lower leg. The surgeon reported CPT 37799 (Unlisted procedure, vascular surgery), but I'm unsure of the anesthesia code.

Answer: Surgical code 37799 crosses to the 10-unit anesthesia code 00350 (Anesthesia for procedures on major vessels of neck; not otherwise specified). However, you won't report this because the physician treated the patient's lower leg, not the neck. Report 01520 (Anesthesia for procedures on veins of lower leg; not otherwise specified) instead. This is only a 3-unit procedure, but is a much more accurate code. Remember that the Crosswalk gives us a lot of good information regarding appropriate anesthesia codes, but it's OK to report something other than the Crosswalk code if it fits the situation better.
