Official Description

Calciferol (Vitamin D)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 82307 refers to the laboratory test for Calciferol, commonly known as Vitamin D. This test involves the analysis of a blood sample to measure the concentration of vitamin D in the body. Vitamin D is a crucial nutrient that plays a significant role in maintaining bone health, supporting immune function, and regulating calcium levels. The assessment of vitamin D levels is essential for diagnosing deficiencies or excesses, which can lead to various health issues, including osteoporosis, rickets, and other metabolic disorders. By determining the vitamin D status in patients, healthcare providers can make informed decisions regarding supplementation, dietary recommendations, and overall health management.

1. Indications

The CPT® Code 82307 is indicated for the assessment of vitamin D levels in patients who may be experiencing symptoms or conditions related to vitamin D deficiency or excess. The following are specific indications for performing this test:

  • Bone Health Assessment Patients with osteoporosis or at risk for bone fractures may require vitamin D level evaluation to ensure adequate bone mineralization.
  • Symptoms of Deficiency Individuals presenting with symptoms such as fatigue, muscle weakness, or bone pain may be tested to determine if low vitamin D levels are contributing to their condition.
  • Monitoring Supplementation Patients undergoing vitamin D supplementation may need periodic testing to monitor their serum levels and adjust dosages accordingly.
  • Chronic Illness Management Patients with chronic illnesses, such as kidney disease or malabsorption syndromes, may require vitamin D level assessments as part of their overall management.

2. Procedure

The procedure for obtaining a vitamin D level using CPT® Code 82307 involves several key steps, which are outlined below:

  • Step 1: Patient Preparation Prior to the blood draw, the patient may be instructed to avoid certain medications or supplements that could affect vitamin D levels. It is essential to ensure that the patient is adequately informed about any necessary preparations.
  • Step 2: Blood Sample Collection A healthcare professional will perform a venipuncture to collect a blood sample, typically from a vein in the arm. The collected blood is then placed in a suitable container for laboratory analysis.
  • Step 3: Laboratory Analysis The blood sample is sent to a laboratory where it undergoes analysis to measure the concentration of calciferol (vitamin D) in the serum. Various methods, such as immunoassays or chromatography, may be employed to obtain accurate results.
  • Step 4: Result Interpretation Once the analysis is complete, the laboratory will provide a report detailing the vitamin D levels. Healthcare providers will interpret these results in the context of the patient's clinical picture and make recommendations based on the findings.

3. Post-Procedure

After the blood sample has been collected for the vitamin D level test, there are generally no specific post-procedure care requirements. Patients may resume their normal activities immediately following the blood draw. However, it is advisable for patients to discuss the results with their healthcare provider to understand the implications of their vitamin D levels and any necessary follow-up actions, such as dietary changes or supplementation. If any adverse reactions occur at the venipuncture site, such as excessive bleeding or signs of infection, patients should seek medical attention.
