CPT® Code 78020

Add-On Code

The CPT® Code 78020 refers to the procedure of assessing thyroid carcinoma metastases through uptake measurements. This procedure is specifically designed to evaluate the functionality of metastatic disease within the thyroid. During the thyroid uptake process, healthcare professionals may conduct single or multiple measurements to ascertain the extent to which iodine is absorbed by the metastatic tissues and the rate of absorption. The procedure involves the administration of radioactive iodine isotopes, such as I-123 or I-131, which can be given orally in either liquid or capsule form. This administration typically occurs approximately four hours prior to the imaging phase of the procedure. Following the administration of the radioactive material, a stationary probe is strategically placed over the area where the metastatic disease is located, allowing for the capture of detailed images. These images are subsequently analyzed by a physician, who provides a written interpretation of the findings, contributing to the overall assessment and management of the patient's condition.
