CPT® Code 80410

The CPT® Code 80410 refers to a specific laboratory test known as the calcitonin stimulation panel, which is utilized primarily for the diagnosis and monitoring of medullary thyroid cancer (MTC), benign C-cell hyperplasia, and multiple endocrine neoplasia type 2 (MEN2). This panel is essential in evaluating the function of C-cells in the thyroid gland, which produce the hormone calcitonin. Calcitonin plays a crucial role in regulating calcium levels in the bloodstream, and its measurement can provide valuable insights into thyroid health and potential malignancies. The procedure involves measuring the baseline level of calcitonin in the blood and observing the changes that occur following the intravenous administration of calcium and/or pentagastrin, both of which stimulate calcitonin release. The thyroid gland, shaped like a butterfly and located at the base of the throat, is responsible for producing not only calcitonin but also other vital hormones such as thyroxin (T4) and triiodothyronine (T3). The test requires the establishment of an intravenous line, which is a separately reportable procedure, and blood samples are collected at various intervals to assess the response of calcitonin levels to the administered stimulants. The analysis of serum or plasma is conducted using a quantitative chemiluminescent immunoassay, ensuring accurate measurement of calcitonin levels for diagnostic purposes.
