Answer. According to the MP/H 2007 Rules, cell differentiation is not coded in bladder tumors. Use Rule H3 and code 8120 (Transitional cell/urothelial cell carcinoma). Rule H3 indicates to code 8120 (transitional cell urothelial carcinoma) when there is: Pure transitional cell carcinoma, flat (non-papillary) transitional cell carcinoma, transitional cell carcinoma with squamous differentiation, transitional cell carcinoma with glandular differentiation, transitional cell carcinoma with trophoblastic differentiation, nested transitional cell carcinoma, or microcystic transitional cell carcinoma.
