I am having some confusion with skin biopsy codes (11100/11101) and shave excision codes (113 series codes).
Here is a scenario as to why:
I performed a billing audit on patient: Jane Doe
Doctor documents: Biopsy/removal via shave technique and/or shave biopsy. check pathology. wound care instructions given.
Diameter of suspicious lesion removed: 1cm verruca like papule
The doctor billed a 11100.
I know that a biopsy was performed, typically with skin biopsies you do not need a diameter, because only part of the lesion is removed. If documentation supports it: the doctor stated he removed the lesion (1cm) and not just a portion would it not be considered a shave excision? Is code selection based on "technique" (shave) or whether or not part of or all of the lesion was removed?
I know with some doctors they just document: biopsy performed or skin biopsy performed with no diameter documented. 11100 is applicable. For some reason the "shave biopsy" verbiage is confusing me. Does this make sense? I am pretty sure it is just the actual "verbiage" that is tripping me up.
