Benign neoplasm of parathyroid gland

This code signifies the presence of a non-cancerous growth originating from the parathyroid glands. These glands, typically four in number, are located in the neck near the thyroid and are responsible for regulating calcium levels in the blood. A benign neoplasm, such as an adenoma, can lead to hyperparathyroidism.

Use this code when documentation explicitly states a benign tumor or adenoma of the parathyroid gland. This is often identified during workups for hypercalcemia or incidentally during neck imaging. Supporting documentation would include pathology reports confirming benignity or imaging reports describing a well-circumscribed parathyroid lesion consistent with an adenoma.

• Do not use this code for malignant parathyroid neoplasms; refer to the appropriate malignancy codes.
• Ensure the documentation specifies "benign" to differentiate from uncertain or unspecified behavior.
• Consider sequencing this code as the primary diagnosis if the benign neoplasm is the reason for the encounter (e.g., for surgical removal of a parathyroid adenoma).
