Official Description

Thyroid uptake; single determination

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 78000 refers to a diagnostic procedure known as thyroid uptake, specifically a single determination. This procedure involves the introduction of radioactive iodine isotopes into the patient's body, which allows for the assessment of the thyroid gland's ability to absorb iodine. The thyroid gland, located in the neck, plays a crucial role in regulating metabolism and overall hormonal balance in the body. By measuring how quickly the iodine is absorbed, healthcare providers can gain valuable insights into the functioning of the thyroid. This single determination is essential for diagnosing various thyroid conditions, including hyperthyroidism or hypothyroidism. It is important to note that if multiple determinations of iodine absorption are required, CPT® Code 78001 should be used. Additionally, if the test is conducted after administering a hormone to enhance iodine uptake, CPT® Code 78003 is applicable. Understanding these distinctions is vital for accurate coding and billing in medical practice.

1. Indications

The thyroid uptake procedure is indicated for various clinical scenarios where assessment of thyroid function is necessary. The following conditions may warrant the use of this procedure:

  • Hyperthyroidism - A condition characterized by an overactive thyroid gland, leading to excessive production of thyroid hormones.
  • Hypothyroidism - A condition where the thyroid gland is underactive, resulting in insufficient hormone production.
  • Thyroid nodules - Abnormal growths within the thyroid that may require evaluation to determine their nature and function.
  • Thyroid cancer - Assessment of thyroid function may be necessary in the context of cancer diagnosis and management.

2. Procedure

The thyroid uptake procedure involves several key steps to ensure accurate measurement of iodine absorption by the thyroid gland. The following outlines the procedural steps:

  • Step 1: Preparation - The patient is prepared for the procedure, which may include fasting or avoiding certain medications that could interfere with iodine absorption. The healthcare provider explains the procedure to the patient, addressing any questions or concerns.
  • Step 2: Administration of Radioactive Iodine - A radioactive iodine isotope is administered to the patient, typically in the form of a capsule or liquid. This isotope is crucial for the subsequent measurement of thyroid uptake.
  • Step 3: Imaging and Measurement - After a specified period, the patient is positioned for imaging. A gamma camera is used to detect the radiation emitted by the absorbed iodine in the thyroid gland. The healthcare provider measures the amount of iodine absorbed, which is recorded as a single determination.

3. Post-Procedure

After the thyroid uptake procedure, the patient may be monitored for any immediate reactions to the radioactive iodine. It is generally advised that patients drink plenty of fluids to help flush the radioactive material from their system. The healthcare provider will discuss any specific post-procedure care instructions, including potential side effects and when to expect results. Follow-up appointments may be scheduled to discuss the findings and any necessary further evaluations or treatments based on the results of the uptake test.
