About D35
D35 is the ICD-10-CM diagnosis code for benign neoplasm of other and unspecified endocrine glands. It belongs to block D10-D36 (benign neoplasms, except benign neuroendocrine tumors) 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: D35.0 (gland), D35.1 (gland), D35.2 (gland), D35.3 (duct), D35.4 (gland), D35.5 (body), D35.6 (paraganglia), D35.7 (glands) and 1 more.
Don't report D35 together with the conditions in its Excludes1 note: benign neoplasm of endocrine pancreas (D13.7), benign neoplasm of ovary (D27.-), benign neoplasm of testis (D29.2.-) and benign neoplasm of thymus (D15.0).
Use an additional code to identify any functional activity.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
