Reader Question:

Why Excisions Don't Add Up

Published on Thu Oct 28, 2004

Question: Would you please explain adding excision sizes together? If the physician excises a lesion (malignant or not), should I add the sizes together?

Maryland Subscriber Answer: You should never add lesion excisions together. You should code excisions (11400-11646) according to the specific site, times the number of excisions the physician performed. For example, you would report 11400 (Excision, benign lesion including margins, except skin tag [unless listed elsewhere], trunk, arms or legs; excised diameter 0.5 cm or less) on the CMS-1500 if the physician removed four lesions.

You may be thinking of repairs, in which case you should add the total of the lengths of the wounds or lacerations repaired together in each type of repair category - simple, intermediate and complex (12001-13160) - according to the body area and location of the wounds or lacerations.
