Question:

EOD-Extension--Bladder: Both papillary transitional cell ca in situ and sessile (flat) transitional cell ca in situ are diagnosed simultaneously in the bladder. We code the higher histology (8130/2). For extension, do we use the code that corresponds to the histology (01), or to the higher extension code (06)?

Discussion:

Answer:

For cases diagnosed between 1998-2003:

Code the EOD-Extension field to 06 [sessile (flat) (solid) carcinoma in situ], the higher extension code.
