0.000What This Code Means
A non-cancerous tumor located in the upper portion of the brain above the tentorium cerebelli.
Coding Tips
- •Supratentorial refers to the area above the tentorium; document this location clearly in the medical record
- •Distinguish between supratentorial and infratentorial locations as they have different treatment implications
Clinical Significance
Benign neoplasm of the supratentorial brain encompasses benign tumors located above the tentorium cerebelli, including tumors of the cerebral hemispheres, basal ganglia, thalamus, and ventricular system. Common supratentorial benign tumors include low-grade gliomas, craniopharyngiomas, and choroid plexus papillomas. Despite their benign histology, these tumors can cause significant morbidity due to mass effect, seizures, and hydrocephalus.
Documentation Requirements
- ✓MRI brain documenting the tumor location as supratentorial with characteristic imaging features.
- ✓If resected, pathology must confirm benign WHO grade.
- ✓Document the specific location within the supratentorial compartment, tumor dimensions, associated symptoms (seizures, headaches, neurological deficits), and management approach.
- ✓Surveillance imaging interval should be specified.
Excludes 1 — Do NOT code together
- benign neoplasm of fourth ventricle (D33.1)
Commonly Confused Codes
D33.1 (infratentorial brain) is for tumors in the posterior fossaD33.2 (brain, unspecified) is used when the supratentorial vs. infratentorial distinction is not documentedD32.0 (cerebral meninges) is for meningeal rather than parenchymal tumorsD43.0 (neoplasm of uncertain behavior, supratentorial) is for tumors with indeterminate biological behavior.
