D37.8

D37.8 — Neoplasm of uncertain behavior of other specified digestive organs

Billable / specific codeICD-10-CM

D37.8 is a billable, specific ICD-10-CM code for neoplasm of uncertain behavior of other specified digestive organs. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

neoplasm of uncertain behavior of anal margin (D48.5)
neoplasm of uncertain behavior of anal skin (D48.5)
neoplasm of uncertain behavior of perianal skin (D48.5)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Neoplasm of uncertain behavior of anal canal
Neoplasm of uncertain behavior of anal sphincter
Neoplasm of uncertain behavior of anus NOS
Neoplasm of uncertain behavior of esophagus
Neoplasm of uncertain behavior of intestine NOS
Neoplasm of uncertain behavior of pancreas

Other codes that can never be billed with D37.8

These codes carry an Excludes1 note pointing at D37.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D37.8 alone.

D44Neoplasm of uncertain behavior of endocrine glands
D48.5Neoplasm of uncertain behavior of skin

Risk adjustment

D37.8 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

D37.8 is named in 30 Medicare coverage policies — 30 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
