Produced when the body is exposed to sunlight, Vitamin D is necessary to absorb calcium and phosphorus needed to maintain bone strength. As every cell in the body had Vitamin D receptors, it plays a key role in important functions such as cell growth modulation, neuromuscular and immune function and inflammation reduction. Evaluation of vitamin D levels is done by measuring the level of 25-hydroxyvitamin D. Medical coding services for Vitamin D deficiency involve coding to the highest level of specificity to report medically necessary screening for Vitamin D deficiency. Medical News Today reports that a 2011 study found that, in general, more than 40 percent of the U.S. population was vitamin D deficient.
Today, the sunshine vitamin is in the news with a new study finding that vitamin D-3 is twice as effective at raising vitamin D levels in the body as vitamin D-2. Researchers say that this may change guidelines. Daily vitamin D dietary recommendations for adults have changed over the years. The Institute of Medicine’s recommended dietary allowance, or RDA, for vitamin D is 600 international units (IU) per day for young adults and 800 IU per day for adults older than 70. However, 1,000 to 2,000 IU per day of vitamin D from a supplement is generally considered safe and adequate. Screening for Vitamin D deficiency is recommended for people with osteoporosis or certain other health conditions. An excess of vitamin D is uncommon, but can lead to hypercalcemia.
Indications for Measurement of Vitamin D Levels
The Centers for Medicaid and Medicare Services (CMS) and commercial payers do not pay for Vitamin D testing for routine screening. According to CMS, measurement of Vitamin D levels is indicated for patients with the following conditions:
- Chronic kidney disease stage III or greater
- Osteoporosis
- Osteomalacia
- Osteopenia
- Hypocalcemia
- Hypercalcemia
- Hypercalciura
- Hypoparathyroidism
- Hyperparathyroidism
- Malabsorption states
- Cirrhosis
- Hypervitaminosis D
- Obstructive jaundice
- Osteosclerosis/petrosis
- Rickets
- Low exposure to sunlight
- Vitamin D deficiency to monitor the efficacy of replacement therapy

Guidelines for Utilization of Vitamin D Testing Services
According to CMS Ruling 95-1 (V), utilization of these services should be consistent with locally acceptable standards of practice. Reimbursement will be provided for only one 25 OH Vitamin D level in any 24 hour period:
- Only one 25 OH vitamin D level will be reimbursed in any 24 hour period. Storage and supplement components will not be reimbursed separately.
- Only one 1, 25-OH vitamin D level will be reimbursed in a 24 hour period if medically necessary.
- Assays of vitamin D levels for conditions other than ICD-10 codes E55.0, E55.9, E64.3, M83.0 – M83.5, and M83.8 – M83.9 are limited to once a year.
- Assays of the appropriate vitamin D levels for ICD-10 codes E55.0, E55.9, E64.3, M83.0 – M83.5, and M83.8 – M83.9 are limited to 4 per year, for the previously identified deficient form of vitamin D.
The patient’s medical record must contain documentation that fully supports the medical necessity for services included within this LCD. This includes, but is not limited to: relevant medical history, physical examination, and results of pertinent diagnostic tests or procedures.
According to the Centers for Disease Control and Prevention (CDC), the number of blood tests for vitamin D levels among Medicare beneficiaries, generally people 65 and older, rose 83-fold from 2000 to 2010, and testing rates rose 2.5-fold from 2009 to 2014 among patients with private insurance. In this scenario, outsourcing medical billing and coding can be a feasible option to ensure that claims are submitted to meet private payers and CMS reimbursement guidelines.
