2007 MP/H Rules
Question:
MP/H Rules/Histology--Bladder: What is the correct histology code for this situation? See discussion.
Discussion:
Patient has 2 bladder tumors, both invasive -- one is transitional cell carcinoma (8120/3) and the other is papillary TCC (8130/3). They have the same extent of disease, both involve the lamina propria. Is this 8120, because of the Note under rule H11 or is this 8130 because under rule H12, it says 'papillary carcinoma and transitional cell carcinoma'? If so, what is the meaning of the note under rule H11?
Answer:
Rule H12 applies, code to 8130.
The note under H11 is intended to explain the order of the rules; that is, why the rule to code papillary transitional/urothelial cell carcinoma (H12) follows the rule to code transitional/urothelial cell carcinoma (H11).
