Primary Site--Lung: What are the guidelines for coding primary site when a lung tumor is described as a hilar mass? See discussion.

At a recent meeting, one registry stated that they apply the following guidelines.

1) If the tumor is described as a hilar mass and there is no mention of LN involvement, Primary Site is coded to hilum (C340)

2) If there is LN involvement along with the mention of a hilar mass, then Primary Site is coded to C349

Assign primary site code C340 when a lung tumor is described as a hilar mass.
