About D37.03

D37.03 is the ICD-10-CM diagnosis code for neoplasm of uncertain behavior of the major salivary glands. It belongs to category D37 (neoplasm of uncertain behavior of oral cavity and digestive organs), 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 4 subcodes must be used instead.

Within D37.0 (neoplasm of uncertain behavior of lip, oral cavity and pharynx), D37.03 is specifically for neoplasm of uncertain behavior of the major salivary glands. Related codes cover lip (D37.01), tongue (D37.02), the minor salivary glands (D37.04), pharynx (D37.05) and other specified sites of the oral cavity (D37.09).

To report this condition, pick the subcode that matches the documentation: D37.030 (glands), D37.031 (glands), D37.032 (glands) and D37.039 (unspecified).

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