D37Neoplasm of uncertain behavior of oral cavity and digestive organs

D37 is the ICD-10-CM diagnosis code for neoplasm of uncertain behavior of oral cavity and digestive organs. It belongs to block D37-D48 (neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 9 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: D37.0 (pharynx), D37.1 (stomach), D37.2 (intestine), D37.3 (appendix), D37.4 (colon), D37.5 (rectum), D37.6 (ducts), D37.8 (organs) and 1 more.

Don't report D37 together with the conditions in its Excludes1 note: stromal tumors of uncertain behavior of digestive system (D48.1-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
