Question:

MP/H Rules/Histology--Lung: How is histology coded for a diagnosis of squamous carcinoma and large cell undifferentiated neuroendocrine carcinoma?

Discussion:

Answer:

For cases diagnosed 2007 or later, apply rule H7 and code the numerically higher ICD-O-3 code, 8070/3 [Squamous cell carcinoma]. See Chart 1, the histology tree in lung equivalent terms. Large cell neuroendocrine carcinoma is histology code 8013/3. The other histology is squamous carcinoma, 8070/3. 8070/3 is higher numerically than 8013/3.
