Vitamin D Deficiency ICD 10: Causes, Symptoms and Treatment

Before exploring Vitamin D Deficiency ICD 10 must have general knowledge of Vitamin D for better understanding. Vitamin D is one of the vitamins which is a basic need for the body to work properly and it is a fat-soluble vitamin that absorbs and uses calcium and phosphorus, which are important for building and maintaining strong bones. It also plays a role in regulating the immune system, reducing inflammation, and supporting muscle function. The sources of Vitamin D are exposure to sunlight, consuming foods that have Vitamin D, and taking supplements.

Why is Vitamin D called Vitamin D?

After vitamins A, B, and C, vitamin D was the fourth vitamin to be discovered, hence its name. Research into the disease rickets, which was common in the 19th century and brought on by a deficiency in vitamin D in the diet, cause the discovery of vitamin D.

The term “vitamin” refers to a group of organic compounds that are essential for normal growth and nutrition but cannot be produced by the body in sufficient quantities and must be obtained from the diet or supplements to maintain a healthy life.

Vitamin D Deficiency ICD 10:

Vitamin D Deficiency is a condition when the body is not producing the required amount of Vitamin D and this lead to shortness of Vitamin D which is called Vitamin D deficiency.

ICD-10 (International Classification of Diseases, 10th Revision) is a system used by healthcare providers to classify and code diseases, injuries, and other health conditions. It is just like a Roll No or Serial Number which we have in college universities and schools as a unique identifier and helps a lot in the record-keeping of students same as the ICD 10 coding system helps in the world of diseases to code every disease differently. Vitamin D deficiency ICD 10 which is also called Vit D deficiency ICD 10  is E55.9.

History Of Vitamin D Deficiency ICD 10:

The specific ICD-10 code for vitamin D deficiency, E55.9, was established as part of this revision. Before ICD-10, there were no specific codes for vitamin D deficiency and it has no unique code, and it was typically classified under more general categories such as “other nutritional deficiencies” or “other specified diseases of the bone and cartilage.”

Healthcare professionals may now identify and code cases of vitamin D deficiency more precisely and explicitly thanks to the inclusion of the E55.9 code in the ICD-10.The ICD-10 system has undergone upgrades and alterations over time, adding new codes and changing some already existing ones. The E55.9 code, on the other hand, continues to indicate vitamin D insufficiency. Here is a study on the deficiency of Vitamin D by Oxford Academic which explores that Vitamin D Deficiency is now becoming a problem in the overall world.

Types of vitamin D Deficiency:

There are 2 major types of Vitamin D Deficiency:

Dietary vitamin D deficiency:

This occurs when a person’s diet does not provide enough vitamin D. This can happen in people who follow a strict vegan diet or who have a malabsorption disorder that prevents them from absorbing enough vitamin D from their food.

Vitamin D Deficiency ICD 10

Sunlight vitamin D deficiency:

This occurs when a person’s skin does not produce enough vitamin D from exposure to sunlight. This can happen in people who live in areas with limited sunlight, wear clothing that covers most of their skin, or spend most of their time indoors. People with darker skin may also be more prone to sunlight vitamin D deficiency because melanin, the pigment that gives skin its color, reduces the skin’s ability to produce vitamin D from sunlight.

Causes of Vitamin D Deficiency ICD 10:E55.9

Every disease has several causes so here are several causes of vitamin D deficiency, including:

Insufficient sun exposure:

The skin produces vitamin D when exposed to sunshine. You might not be getting enough vitamin D if you spend a lot of time indoors or if you reside in an area with little sunlight.

Low dietary intake:

Natural sources of vitamin D include fatty fish, egg yolks, and certain mushrooms. Nevertheless, the majority of people do not consume enough vitamin D in food.

Vitamin D Deficiency ICD 10

Malabsorption disorders:

The body’s capacity to absorb vitamin D from food can be hampered by illnesses like celiac disease, Crohn’s disease, and cystic fibrosis.


As a fat-soluble vitamin, vitamin D is stored in fat tissue, which contributes to obesity. Vitamin D levels in obese people may be reduced because it is stored in fat rather than being available in the bloodstream.

Kidney or liver disease:

The liver and kidneys are involved in the conversion of vitamin D to its active form. People with liver or kidney disease may have impaired vitamin D metabolism, leading to deficiency.

Symptoms of Vitamin D Deficiency ICD 10:E55.9

Symptoms of vitamin D deficiency can change depending on the level of the deficiency. Some common symptoms of vitamin D deficiency include:

Bone pain or tenderness:

Vitamin D is important for maintaining bone health, so a deficiency can lead to bone pain or tenderness.

Weakness Of Muscle:

Vitamin D helps to regulate muscle function, so a deficiency can cause muscle weakness.


Vitamin D deficiency has been associated with increased fatigue and decreased energy levels.


Some studies have linked vitamin D deficiency with an increased risk of depression.

Impaired wound healing:

Vitamin D is important for wound healing so a deficiency can impair the body.

These all are generalized symptoms of vitamin D deficiency. If any person feels symptoms continuously should go to the doctor.

Health Risks Associated with Vitamin D Deficiency ICD 10:

Every disease increases the risk of many other diseases. Vitamin D deficiency can increase the risk of several health problems, including:

Vitamin D Deficiency ICD 10


Vitamin D insufficiency can result in decreased bone density, which makes bones more brittle and raises the risk of fractures. Vitamin D is essential for bone health.

Cardiovascular disease:

Heart disease, high blood pressure, and stroke are all at an elevated risk when there is a vitamin D deficit.

Type 2 diabetes:

Vitamin D deficiency has been linked to an increased risk of type 2 diabetes, although more research is needed to fully understand this connection.

Respiratory infections:

Vitamin D is important for immune function, and a deficiency may increase the risk of respiratory infections, such as the common cold, flu, and pneumonia.

Cognitive impairment:

Some studies have suggested that vitamin D deficiency may be associated with an increased risk of cognitive impairment and dementia.

Diagnosis and Treatment of Vitamin D Deficiency:


The level of vitamin D in the blood can be used to diagnose vitamin D insufficiency. The standard test is called the 25-hydroxyvitamin D blood test (25(OH)D), which measures the level of vitamin D in the bloodstream. A level below 20 nanograms per milliliter (ng/mL) is considered deficient, while levels between 20 and 30 ng/mL are considered insufficient.


Increasing vitamin D intake through diet, supplements, or sunshine exposure is the primary treatment for vitamin D deficiency. The degree of the deficiency and the underlying cause will determine the recommended course of treatment. Increasing sunshine exposure and including foods high in vitamin D in the diet may be adequate for mild cases. Supplementing with high-dose vitamin D may be required in more severe situations.

Prevention Of Vitamin D Deficiency ICD 10:

Prevention of vitamin D deficiency involves ensuring adequate intake of vitamin D through:


Include vitamin D-rich foods in your diet, such as fatty fish (e.g. salmon, tuna, mackerel), egg yolks, fortified dairy products, and fortified cereals.


Consider taking a vitamin D supplement if you are at risk of deficiency or if you have been diagnosed with a deficiency.

Sun exposure:

Spend some time outdoors in the sun each day, especially when the sun is strongest (usually between 10 a.m. and 3 p.m.).


What is the ICD code 10 for vitamin D deficiency?
The ICD-10 code for vitamin D deficiency is E55.9. This code falls under the category of “nutritional deficiencies” and specifically refers to “Vitamin D deficiency, unspecified”.
What causes vitamin D deficiency?
Limited sun exposure and poor diet and certain medical conditions lead to vitamin D deficiency.
What is vitamin D deficiency ICD-9?
The ICD-9 code for vitamin D deficiency is 268.9. However, it’s important to note that the ICD-9 code system was replaced by the ICD-10 system on October 1, 2015. Therefore, healthcare providers now use the ICD-10 code system to diagnose and report vitamin D deficiency. The ICD-10 code for vitamin D deficiency is E55.9.



In summary, vitamin D deficiency is a common disorder that can be brought on by a variety of things, including insufficient sun exposure, a poor diet, malabsorption, obesity, kidney or liver disease, and some drugs can cause lake of vitamin D. A lack of vitamin D can cause a variety of symptoms, such as muscle weakness, bone discomfort, and an increased risk of fractures and chronic illnesses. E55.9 is the ICD-10 code for a lack of vitamin D.

Thankfully, vitamin D deficiency is quickly detected by blood testing, and it can be treated with vitamin D supplements and lifestyle changes like more sun exposure and a healthy diet. To avoid long-term health issues, vitamin D insufficiency must be treated right away. It is not a deadly disease but if we don’t consider it may lead to serious conditions.

In order to promote the best possible health and wellness, it is critical for healthcare professionals and individuals to understand the causes, symptoms, and treatment of vitamin D deficiency.
