Question:

MP/H/Histology--Lung: Would you code a lung primary of "non-small cell carcinoma with neuroendocrine differentiation" to non-small cell carcinoma (8046/3) or carcinoma with neuroendocrine differentiation (8574/3)? See discussion.

Discussion:

The pathology report states "Right mediastinal mass: poorly differentiated non-small cell carcinoma with neuroendocrine differentiation." This is the only histologic confirmation of this lung primary that is collected.

Answer:

Code carcinoma with neuroendocrine differentiation (8574/3). MP/H rule H7 applies: code the higher ICD-O-3 code. There is non-small cell lung carcinoma (8046/3) and a carcinoma, NOS with neuroendocrine differentiation present (8574/3).
