Question:

Grade, Differentiation--Bladder: How is this field coded for a five grade system? See Description.

Discussion:

Example: Invasive, high grade transitional cell carcinoma (Grade 4-5/5)

Answer:

For this example, code grade as 4 based on the term "High grade." If "high grade" was not stated, the grade would be coded as 9, not determined. There is no SEER translation between the ICD-O grades and a five grade system for bladder. None of the pathololgist experts we querried knew of a five grade system for bladder.
