Benign neoplasm of brain, infratentorial

This code signifies the presence of a non-cancerous tumor located in the infratentorial compartment of the brain. This region includes structures such as the cerebellum and brainstem. The neoplasm is characterized by slow growth and a lack of metastatic potential.

Apply this code when documentation confirms a benign intracranial tumor specifically localized below the tentorium cerebelli. This diagnosis is typically established through imaging studies (e.g., MRI, CT) and often confirmed by biopsy. Use this code for initial diagnosis, follow-up, or management of such a lesion.

• Ensure documentation explicitly states "benign" and "infratentorial" to support this specific code.
• Distinguish from D33.0 (supratentorial) and D33.2 (unspecified) based on precise anatomical location.
• Do not use for malignant or uncertain behavior neoplasms; refer to C71.- or D43.- series, respectively.
