D33Benign neoplasm of brain and other parts of central nervous system

D33 is the ICD-10-CM diagnosis code for benign neoplasm of brain and other parts of central nervous system. 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: D33.0 (supratentorial), D33.1 (infratentorial), D33.2 (unspecified), D33.3 (nerves), D33.4 (cord), D33.7 (system) and D33.9 (unspecified).

Don't report D33 together with the conditions in its Excludes1 note: angioma (D18.0-), benign neoplasm of meninges (D32.-), benign neoplasm of peripheral nerves and autonomic nervous system (D36.1-), hemangioma (D18.0-) and 2 more.

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