D43.0 is the authoritative medical code for Neoplasm of uncertain behavior of brain, supratentorial. This classification is used in medical billing and clinical recording to specify the clinical criteria for neoplasm of uncertain behavior of brain, supratentorial (ICD-10-CM D43.0), ensuring healthcare documentation aligns with 2026 federal coding standards.
Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.
