Benign neoplasm of pineal gland

This code signifies the presence of a non-cancerous tumor originating in the pineal gland, a small endocrine gland in the brain. These neoplasms are typically slow-growing and do not metastasize, but their location can still cause symptoms due to compression of surrounding brain structures.

Use this code for documented cases of a benign pineal gland tumor, often identified through imaging studies like MRI or CT scans. This diagnosis is typically confirmed by a pathologist's report following biopsy or surgical excision.

• Ensure documentation explicitly states "benign" to differentiate from malignant or uncertain behavior neoplasms.
• Do not confuse with pineal cysts, which are typically non-neoplastic and coded differently.
• Sequence as a primary diagnosis when the benign pineal neoplasm is the reason for the encounter, or as a secondary diagnosis if it's an incidental finding or comorbidity.
