ABN and acne treatment

I've searched CMS's site for LCD/NCD information for acne treatment, CPT 10040, and can find no information. I also see that this CPT code is active in the physician fee schedule. Do I need to provide an ABN for Medicare patients undergoing this type of treatment?

Abn

I would provide an ABN, just in case.
