Question:

CS Extension--Bladder: How should this field be coded for a high grade urothelial carcinoma with "focal micropapillary features and invasion of lamina propria, with a note stating there is invasive carcinoma focally involving thin muscle bundles...difficult to distinguish whether muscularis propria or muscularis mucosae"?

Discussion:

Answer:

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Assign CS Extension code 15 [Invasive tumor confined to subepithelial connective tissue (tunica propria, lamina propria, submucosa, stroma)]. The information provided confirms invasion of the lamina propria (code 15) but is not definitive enough to assign a code higher than 15.
