Question:
MP/H Rules/Primary Site--Bladder: How is the primary site coded when a patient is diagnosed with synchronous, non-invasive papillary urothelial carcinomas of the bladder and renal pelvis? See Discussion.
Discussion:
This patient was diagnosed with at least three non-invasive papillary urothelial carcinomas of the bladder in 11/09. The patient subsequently underwent a complete nephroureterectomy in 12/09 showing a single non-invasive papillary urothelial carcinoma of the renal pelvis.
Per the MPH Rule M8, this is a single primary. Is the primary site to be coded C659 [renal pelvis] or C689 [urinary system, NOS]?
Answer:
Assign code C68.9 when multiple tumors are found in multiple urinary sites at the same time.
