What has happened to this code

Official coding rules
Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.
Inherited from D37 Neoplasm of uncertain behavior of oral cavity and digestive organs
Excludes1 - never coded here
- stromal tumors of uncertain behavior of digestive system (D48.1-)
Inherited from the D37-D48 section Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes (D37-D48)
Excludes1 - never coded here
- neoplasms of unspecified behavior (D49.-)
Note
- Categories D37-D44, and D48 classify by site neoplasms of uncertain behavior, i.e., histologic confirmation whether the neoplasm is malignant or benign cannot be made.
