vitamin D levels repeat after 3-6 months on recommended replacement therapy. 7 Whilst on maintenance vitamin D doses recheck bone profile and vitamin D levels if symptoms suggestive of vitamin D toxicosis or hypercalcaemia (confusion, polyuria, polydipsia, anorexia, vomiting or muscle weakness) are present.

How do you know if you have low vitamin D?
2. For 82306: If more than one LCD-listed condition contributes to Vitamin D deficiency in a given patient and/or is improved by Vitamin D administration, coders should use: ICD-10 E55. 9 UNSPECIFIED VITAMIN D DEFICIENCY. This code should not be used for any other indication.
Reference Range. The major circulating form of vitamin D is 25-hydroxyvitamin D (25(OH)D); thus, the total serum 25(OH)D level is currently considered the best indicator of vitamin D supply to the body from cutaneous synthesis and nutritional intake. The reference range of the total 25(OH)D level is 25-80 ng/mL.
The test can determine if your vitamin D levels are too high or too low. The test is also known as the 25-OH vitamin D test and the calcidiol 25-hydroxycholecalcifoerol test. It can be an important indicator of osteoporosis (bone weakness) and rickets (bone malformation).
ICD-10 code E55. 9 for Vitamin D deficiency, unspecified is a medical classification as listed by WHO under the range - Endocrine, nutritional and metabolic diseases .
Low vitamin D levels can cause health problems, such as rickets and osteomalacia. A 25-hydroxy vitamin D test can help someone determine whether they have a deficiency or are at risk of developing one. It is possible to get enough vitamin D by going outside in the sunlight each day.
Lower than normal 25-OH vitamin D levels can result from a dietary deficiency, poor absorption of the vitamin or impaired metabolism of the sterol in the liver. A 25-OH vitamin D deficiency can lead to bone diseases such as rickets and osteomalacia. Above normal levels can lead to hypercalcemia.
There are several reasons for this. The circulating half life of circulating 1,25(OH)D is only 4-6 hours. Circulating levels of 1,25(OH)D are a thousand fold less than 25(OH)D. As a patient becomes vitamin D deficient, there is a decrease in intestinal calcium absorption which lowers ionized calcium transiently.
What's the difference between vitamin D and vitamin D3? There are two possible forms of vitamin D in the human body: vitamin D2 and vitamin D3. Both D2 and D3 are simply called “vitamin D,” so there's no meaningful difference between vitamin D3 and just vitamin D.
Vitamin D3 is cholecalciferol and comes from animal-based sources. Both supplements are processed in the body by the liver to 25-hydroxyvitamin D, though vitamin D3 is thought to provide higher levels of 25D.
Measurement of 1, 25-OH Vitamin D level is indicated for patients with: unexplained hypercalcemia (suspected granulomatous disease or lymphoma) unexplained hypercalciuria (suspected granulomatous disease or lymphoma) suspected genetic childhood rickets.

History/Background and/or General Information Vitamin D, a group of fat-soluble prohormones, is an essential Vitamin. There are two major types of Vitamin D (Vitamin D2 and Vitamin D3) which are collectively known as calciferol.
This test is not the same as Calcitriol (1,25 di-OH Vitamin D) [081091] (vitamin D 3 ), which must be ordered separately.
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
If tube other than a gel-barrier tube is used, transfer separated serum to a plastic transport tube.
Values of vitamin D vary with exposure to sunlight.
Immunochemiluminometric assay (ICMA). This assay is performed on the DiaSorin LIAISON® instrument in multiple laboratories throughout LabCorp. This highly automated test measures both D 2 and D 3 together and reports a total 25-hydroxy vitamin D.
The majority of 25-OH vitamin D (25-D) in the circulation is derived from the conversion of 7-dehydrocholesterol in the skin that is irradiated with ultraviolet radiation in the UVB range (wavelength 290 nm to 315 nm).
