Question:

CS Lymph Nodes--Breast: Now that code 50 [fixed/matted ipsilateral axillary LNS, NOS] is obsolete, how is this field coded for a case in which there are clinically matted lymph nodes, no neoadjuvant therapy, and no lymph node size on the available pathology report?

Discussion:

Answer:

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.From the American College of Surgeons: The pathologic information always takes precedence over the clinical information when there is no neoadjuvant therapy. The size reference is that this is not ITC or micromets. Clinically, I don't think you can have fixed or matted nodes that aren't greater than micromets. This would be coded to 52. The mapping for all of these codes is not taken from this, but from the value of SSF3 per the note at the bottom of the table. See CS Lymph Nodes note 2.
