Benign neoplasm of pituitary gland

This code signifies a non-cancerous growth originating from the pituitary gland. These benign tumors, often adenomas, can cause various symptoms due to hormone overproduction or mass effect on surrounding structures.

Use this code for documented cases of a benign pituitary neoplasm, such as a pituitary adenoma, identified through imaging (e.g., MRI) and/or confirmed by biopsy. It is appropriate when the tumor is not classified as malignant or of uncertain behavior.

• Distinguish carefully between benign, malignant (C75.1), and uncertain behavior (D44.3) pituitary neoplasms based on pathology reports or definitive clinical statements.
• Code any associated endocrine disorders (e.g., hyperprolactinemia, Cushing's disease) separately as secondary diagnoses.
• Ensure documentation specifies the benign nature of the neoplasm; "pituitary tumor" alone is insufficient for this specific code.
