CPT® Code 60502

The CPT® Code 60502 refers to the procedure known as parathyroidectomy or exploration of the parathyroid glands, specifically indicating a re-exploration. This surgical intervention is typically performed when there is a need to investigate or remove one or more of the parathyroid glands, which are small endocrine glands located behind the thyroid gland. There are four parathyroid glands, with two situated in each lobe of the thyroid, positioned at the upper and lower lateral aspects. These glands play a crucial role in regulating calcium levels in the bloodstream by secreting parathyroid hormone (PTH). When blood calcium levels decrease, the parathyroid glands release PTH to elevate those levels, and conversely, they cease secretion when calcium levels normalize. The procedure is often indicated in cases of parathyroid adenomas, which are benign tumors that lead to hyperparathyroidism due to excessive production of PTH. During the surgery, a transverse incision is made in the neck, allowing access to the thyroid and parathyroid glands. The surgeon elevates the thyroid to expose the enlarged parathyroid gland, which is then dissected from surrounding tissues and excised. If additional parathyroid glands are found to be enlarged, they may also be removed. In instances where all four glands are excised, a parathyroid autotransplantation may be performed, where small pieces of normal parathyroid tissue are implanted into a muscle, often the sternocleidomastoid or forearm muscle, to preserve parathyroid function. This procedure is critical for managing conditions related to abnormal calcium metabolism and ensuring the patient's long-term health.
