Question:

MP/H Rules/Histology--Lung: How is micropapillary adenocarcinoma of the lung coded given that a literature search indicates that this is a distinct subtype of adenocarcinoma of the lung with poor prognosis?

Discussion:

Answer:

Code the histology to 8260/3 [papillary adenocarcinoma]. An expert pathologist states that the WHO notes micropapillary to be a pattern seen in papillary carcinomas, but does not specify it as a separate histologic type.
