You will need a modifier 59 on the 11900 but we do this all the time and have had no issue getting paid and we have yet to be asked for notes or medical proof. However going into doing this the forst time we did think that might be an issue. so far so ok!You are going to run into problems. They carrier is going to think you are treating the "same" warts with the claim.
They will also question why you chose one method over the other and not the same treatment for all.
Also, reimbursement for J3490 is "iffy" and you may have trouble getting paid for that. (Unclassified drug). This will require a manual claim and a cover letter.
Perhaps on this claims cover letter, you can also CLEARLY let them know that some were destroyed with candida antigen and others destroyed traditionally with LN2. I.e., separate lesions and why some were treated one way vs the other.
11900 and 17110 are also bundled.
Put an XS (or 59) on the 11900 to indiciate separate lesion(s) that were treated with injection.
17110
11900 -XS (or 59)
