Benign neoplasm of brain

This code represents a non-cancerous growth originating within the brain tissue or its immediate coverings. These benign tumors do not metastasize to other parts of the body but can still cause significant neurological symptoms due to compression of brain structures.

Use this code when documentation clearly indicates a benign neoplasm of the brain, such as an astrocytoma (grade I or II), meningioma, or pituitary adenoma, that has been definitively diagnosed as non-malignant. This code is appropriate for initial diagnosis, treatment, and follow-up care for such conditions.

• Always confirm the benign nature of the neoplasm; if malignant, a code from the 191 series would be appropriate.
• Specify the exact location of the benign neoplasm (e.g., cerebrum, cerebellum) if known, using a more specific subcategory if available.
• Do not use this code for secondary metastatic brain tumors; those would be coded as secondary malignant neoplasms.
