[Histonet] billing question

[Eck, Allison]

I am looking for advice on a current billing problem.

Breast specimens: We recieve the lumpectomy with orienting sutures - 88307
along with that are the accompanying margins (inferior, superior, medial, etc).  Our breast surgeon has been placing orienting sutures on all of her margins.  We had previously been billing under the assumption that the unsutured margins were 88305, but now with the sutures should we be billing an 88307 or still 88305 since they are margins?

Thank you in advance for your help

Allison
