11200-XS and 17110 or 17110 alone? Insurance is Medicare. From the CPT descriptions, I think both can be billed, but some providers think it should be 17110 alone when the skin tags are destroyed with cryotherapy. I'm doubting myself because I'm being questioned a lot!

Verruca Vulgaris, on the scalp
Procedure: Destruction with cryotherapy
Number: 1
Discussed procedure and expectations including risks and benefits. Verbal consent obtained. Treated with LN2. There were no complications. Patient tolerated the procedure well. Post-procedure expectations and wound care were reviewed.

Skin tags on neck
Procedure: Destruction with cryotherapy
Number: 2
Discussed procedure and expectations including risks and benefits. Verbal consent obtained. Treated with LN2. There were no complications. Patient tolerated the procedure well. Post-procedure expectations and wound care were reviewed.

CPT descriptions:
11200 - The physician removes skin tag lesions. The physician uses sharp excision with scissors or scalpel, chemical cautery, electrical cautery, ligature strangulation, or any combination of these methods. (chemical cautery includes cryotherapy, doesn't it?)
17110 - The physician uses a laser, electrosurgery, cryosurgery, chemical treatment, or surgical curettement to obliterate or vaporize benign lesions other than skin tags or lesions such as cutaneous vascular proliferative lesions. Examples of lesions that may be removed under this code description include, but are not limited to, molluscum contagiosum or melanocytic nevi. (This specifically says "other than skin tags")
 
You are correct; stand your ground with the providers. As per the description you've given for CPT 17110, that code is for lesions 'other than skin tags or vascular proliferative lesions'. It would be incorrect coding to report treatment of skin tags with 17110. It could also cause an incorrect payment since the coverage rules for treatment of skin tags are different for those for other benign lesions. You need to use the 11200-11201 codes for the skin tags.
