ICD-10:

Answer 'Where?' for Adenomatous Colon Polyps

You’ll need more info in 2015.

When your pathologist diagnoses an adenomatous polyp submitted from a colonoscopy, you’ll need to know much more information to choose the proper ICD-10 code. 
 
Make sure you train your pathologists to document the proper details so you can properly code these cases when ICD-10 goes into effect on Oct. 1, 2015.
From One to Many
 
You just need one code for adenomatous colon polyp under ICD-9: 211.3 (Benign neoplasm of colon).
But once ICD-10 goes into effect, things get more complicated. That’s because the ICD-10 diagnosis varies based on location, as you can see in the following codes: 
  • D12.2 — Benign neoplasm of ascending colon
  • D12.3 — Benign neoplasm of transverse colon
  • D12.4 — Benign neoplasm of descending colon
  • D12.5 — Benign neoplasm of sigmoid colon.
Saving grace: If the surgeon doesn’t document where the polyp came from, or your pathologist doesn’t pass on that information in the pathology report, you still have an option for reporting the diagnosis: D12.6 (Benign neoplasm of colon, unspecified).
