2007 MP/H Rules. Colon (H18)

Question:

MP/H Rules/Histology--Colon: If a tubulovillous (TV) adenoma is in situ and other polyp(s) have an invasive component, does the in situ TV adenoma still have priority and should rule H18 be applied?

Discussion:

Answer:

For cases diagnosed 2007 or later, always give precedence to coding the invasive. Rule H18 applies UNLESS the adenocarcinoma in the TV is in situ and the others are invasive. In this case, code the histology of the invasive adenocarcinoma.

This clarification will be added when the MP/H manual is revised.
