Benign neoplasm of brain, supratentorial

This code signifies the presence of a non-cancerous growth originating within the supratentorial compartment of the brain. These benign tumors, while not metastatic, can still cause neurological symptoms due to their mass effect on surrounding brain tissue.

Use this code for documented benign neoplasms located above the tentorium cerebelli, such as meningiomas, pituitary adenomas, or craniopharyngiomas, when they are confined to the supratentorial region. Documentation should clearly state the benign nature and the supratentorial location of the tumor.

• Ensure the documentation explicitly states "benign" and "supratentorial" to avoid miscoding.
• Do not use this code if the neoplasm is malignant or of uncertain behavior; refer to the appropriate C-series or D49 codes.
• Remember the Excludes1 note: never code this with D33.1 (benign neoplasm of fourth ventricle).
