About D35.0

D35.0 is the ICD-10-CM diagnosis code for benign neoplasm of adrenal gland. It belongs to category D35 (benign neoplasm of other and unspecified endocrine glands), 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 3 subcodes must be used instead.

Within D35 (benign neoplasm of other and unspecified endocrine glands), D35.0 is specifically for benign neoplasm of adrenal gland. Related codes cover parathyroid gland (D35.1), pituitary gland (D35.2), craniopharyngeal duct (D35.3), pineal gland (D35.4), carotid body (D35.5), aortic body and other paraganglia (D35.6), other specified endocrine glands (D35.7) and endocrine gland, unspecified (D35.9).

To report this condition, pick the subcode that matches the documentation: D35.00 (gland), D35.01 (gland) and D35.02 (gland).

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.
