D37 vs D48.1
D37 (Neoplasm of uncertain behavior of oral cavity and digestive organs) compared with D48.1 (Neoplasm of uncertain behavior of connective and other soft tissue), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. D37 carries an Excludes1 note covering D48.1: “stromal tumors of uncertain behavior of digestive system (D48.1-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
