CPT code 82306 describes a test measuring the level of 25-hydroxyvitamin D in a patient’s blood. This procedure is considered the most accurate measure of vitamin D status and usually requires a blood sample.
What Is CPT Code 82306?
CPT 82306 describes a test measuring the level of 25-hydroxyvitamin D in a patient’s blood.
This test is considered the most accurate method for measuring vitamin D status because 25-hydroxyvitamin D is the main form of vitamin D circulating in the bloodstream and is known for its accuracy and precision.
82306 usually requires a blood sample, and it is performed in a laboratory.
The CPT book describes CPT code 82306 as: “Vitamin D; 25 hydroxy, includes fraction(s), if performed.”
The lab analyst quantifies vitamin D levels in a blood sample, typically using an immunoassay method. This method relies on the reaction between an antigen (the analyte) and an antibody to accurately measure the hormone level.
The test explicitly measures the primary circulating form of vitamin D and helps regulate calcium and phosphorus levels in the body.
Vitamin D has many other effects on the body, as it can regulate the expression of hundreds of genes through its receptors.
Practitioners use this test to diagnose and treat deficiency, malabsorption, and related disorders. It is typically ordered when deficiency is suspected or when a patient is being monitored while taking vitamin D supplements.
How To Use CPT 82306
Using CPT code 82306 is appropriate when a lab analyst measures the level of total vitamin D in a patient’s blood.
This test is considered the most accurate method for measuring vitamin D status because 25-hydroxyvitamin D is the main form of vitamin D circulating in the bloodstream and can be measured with a high degree of accuracy and precision.
The lab also performs measurements of fractions of vitamin D2 and/or vitamin D3. These are included in the same code and are not billable separately.
This means that if the lab performs additional testing or measurements on the same sample, such as measuring a specific fraction of 25-hydroxyvitamin D, that would be included in the same code, and it is not necessary to bill additional codes for those tests.
Providers may also order this test with other names, such as 25-OH vitamin D, 25-hydroxycholecalciferol, 25(OH)D, calcifediol, and calcidiol.
However, you can use CPT 82652 for a test for 1,25-dihydroxy vitamin D.
