I have a surgeon who less than 30 days prior perfomed a 19125 for bloody discharge from left nipple. Excised the duct and submitted it to pathology. Now the surgeon wants a 99215 for a 45 minute, 100% consultation for DCIS.

Would the 99215 be billable with a 24 modifier? Nothing documented about carcinoma in the procedure visit, everything was nipple discharge. However, because it is the same anatomy, would that place this encounter unbillable?

Appreciate any feedback
