D37Neoplasm of uncertain behavior of oral cavity and digestive organs

Non-billable headerICD-10-CM

D37 is a non-billable header ICD-10-CM code for neoplasm of uncertain behavior of oral cavity and digestive organs. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

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

  • stromal tumors of uncertain behavior of digestive system (D48.1-)

Other codes that can never be billed with D37

These codes carry an Excludes1 note pointing at D37. 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 alone.

  • D38.0Neoplasm of uncertain behavior of larynx
  • D44Neoplasm of uncertain behavior of endocrine glands
  • D48.5Neoplasm of uncertain behavior of skin

Risk adjustment

D37 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.

Code to one of these instead D37

9 child codes. Green means billable.
