CPT® Code 60500

The procedure described by CPT® Code 60500 refers to a parathyroidectomy or exploration of the parathyroid glands. The parathyroid glands are small, pea-sized glands located behind the thyroid gland, with two glands situated in each lobe of the thyroid. Their primary function is to regulate calcium levels in the bloodstream by secreting parathyroid hormone (PTH). When blood calcium levels drop, the parathyroid glands release PTH to increase calcium levels, and conversely, they cease secretion when calcium levels normalize. This procedure is typically indicated when there is an enlargement of one or more parathyroid glands, often due to a parathyroid adenoma, which leads to hyperparathyroidism characterized by excessive production of PTH. During the parathyroidectomy, a transverse incision is made in the neck, allowing the surgeon to access the thyroid and parathyroid glands. The enlarged gland is carefully dissected from surrounding tissues and excised. The surgeon may also examine the remaining parathyroid glands to ensure they are of normal size, removing any additional enlarged glands as necessary. In cases where all four parathyroid glands are removed, a parathyroid autotransplantation is performed, where small pieces of normal parathyroid tissue are implanted into a muscle, typically the sternocleidomastoid muscle or a muscle in the forearm, to preserve parathyroid function. This procedure is critical for managing conditions related to abnormal calcium metabolism and ensuring the patient's long-term health and hormonal balance.
