ICD 10 Code For Hypothyroidism (2023) (2023)

The ICD 10 code is used by doctors to document problems like Hypothyroidism. The ICD 10 code for hypothyroidism is used to indicate a diagnosis of hypothyroidism listed by the World Health Organization under a range of Endocrine, nutritional and metabolic diseases. ICD 10 Code For Hypothyroidism is E03. 9 for unspecified and E03.8 for specified hypothyroidism.

In the medical world, different codes are used for different diseases. The ICD-10 code E03 is used for hypothyroidism. Hypothyroidism is a medical condition or disease where the thyroid gland fails to produce enough hormones for the body to function smoothly. icd 10 code The most common causes of hypothyroidism are autoimmune diseases (Hashimoto’s thyroiditis).

ICD 10 code for hypothyroidism is E03. The full code is E03.0, which stands for “primary hypothyroidism.” This code is used to describe a condition in which the thyroid gland does not produce enough hormones, resulting in decreased metabolism and a wide range of symptoms, including fatigue, weight gain, cold intolerance, and Depression included.

Hypothyroidism can cause symptoms such as fatigue, weight gain, cold intolerance, constipation, dry skin and depression. It is diagnosed through a blood test that measures thyroid hormone levels and TSH. To know in detail about icd 10 code for hypothyroidism, read today’s article completely.

What is Hypothyroidism?

Hypothyroidism is a common and lifelong health condition that cannot be prevented. It can basically be defined as the situation where the thyroid gland does not produce enough hormones for maintaining good health.

Hypothyroidism is a condition in which the thyroid gland stops producing enough hormones to regulate metabolism in the body. This can result in a range of symptoms including fatigue, weight gain, cold intolerance, constipation, depression and dry skin. icd 10 code for hypothyroidism is used, it can be caused by autoimmune diseases such as Hashimoto’s thyroiditis, radiation therapy, surgery to remove the thyroid gland, and certain medications. Although in some cases, the cause may be unknown.

Hypothyroidism is usually diagnosed through a blood test that measures levels of thyroid hormones and thyroid-stimulating hormone (TSH). Treatment involves taking daily hormone replacement therapy in the form of levothyroxine, which is a synthetic form of the thyroid hormone thyroxine. It is diagnosed under icd 10 code for hypothyroidism.

These hormones that are released by the thyroid gland help in regulating the body and providing energy to almost every organ present in the body.

Besides that, it also promotes the health of the heart and the working of the digestive system. Hypothyroidism is caused due to Hashimoto’s Thyroiditis which is an autoimmune condition.

The risk of hypothyroidism is higher in women and people who are 60 years of age, can go under such health hazards. Even the ones with a family history of hypothyroidism or who are going through any kind of autoimmune conditions like type 1 diabetes are likely to get hypothyroidism as well.

What causes Hypothyroidism?

icd 10 code hypothyroidism is a condition characterized by an underactive thyroid gland, which results in reduced or stopped production of thyroid hormones. There are many causes of hypothyroidism, including:


● Autoimmune disorders:- The most common cause of hypothyroidism is Hashimoto’s thyroiditis, an autoimmune disorder that occurs when the immune system attacks and destroys the thyroid gland.

●Iodine Deficiency:- Iodine is an essential component of thyroid hormones, and iodine deficiency can lead to hypothyroidism.

● Thyroid surgery:- Surgical removal of the thyroid gland for the treatment of thyroid cancer can lead to hypothyroidism.

●Radiation therapy: Radiation therapy to the neck and head, such as for cancer treatment, can damage the thyroid gland and cause hypothyroidism.

●Certain medications: Some medications, such as lithium and amiodarone, can interfere with the production of thyroid hormones and cause hypothyroidism.

What Complications One Might Suffer in Hypothyroidism?

If a person develops hypothyroidism then chances are that the person will suffer from the complications that are mentioned below.

  • Balance problems
  • Goiter
  • Heart problems
  • Infertility
  • Joint pains
  • Mental illness
  • Obesity and
  • Peripheral neuropathy

If a pregnant lady suffers from hypothyroidism then the chances of affecting the baby in different ways are high. It is possible that the child can be born with undeveloped mental health.

What are the Common Signs of Hypothyroidism?

The signs of hypothyroidism can vary from one person to another where the early symptoms can include gaining weight and fatigue. Other than that, some of the common signs of hypothyroidism include,

  • Fatigue
  • Sensitive face
  • Depression
  • Constipation
  • Weight gain
  • Feeling cold
  • Less sweating
  • Reduced heart rate
  • Dry skin and hair
  • Menstrual problems
  • Problems with Fertility
  • Pain in joints
  • Weakness in muscles and more

Hypothyroidism is a condition where the thyroid gland does not produce enough hormones, causing the body’s metabolism to slow down. The six common symptoms of hypothyroidism are as follows:

Feeling tired with light exertion:- People with hypothyroidism often feel tired and have low energy levels, even after getting enough sleep.

Persistent weight gain :- A slow metabolism can cause weight gain, even if the person’s diet and activity level remain unchanged.

Cold intolerance: People with hypothyroidism feel cold even in hot weather. Or in addition their tolerance to cold temperatures may be reduced.

Dry skin :- The skin may become dry, rough and flaky and the hair may become brittle and dull.

Symptoms of constipation: – In hypothyroidism, the digestive system slows down, due to which constipation occurs.

Depression: Hypothyroidism can cause a persistent feeling of sadness and fatigue, which can lead to depression and lead to depression.

Sometimes the symptoms are hard to find but they might get easily identified as the thyroid slows down. Though the problem is lifelong it can be maintained if treated properly and through regular medication help.

The main aim of the treatment for hypothyroidism includes reduction and normalization in the production of thyroid hormones. Make sure that you take the medications regularly as prescribed by the doctor to avoid the complications from coming back again.

What is Subclinical Hypothyroidism?

Subclinical hypothyroidism is a condition where a person has an elevated TSH (thyroid-stimulating hormone) level and normal levels of T4 (thyroxine), which is the main hormone produced by the thyroid gland. This means that the thyroid gland is not producing enough thyroid hormone, but not enough to cause noticeable symptoms. It can often be detected during routine blood tests and is generally considered a mild form of hypothyroidism. Some people with subclinical hypothyroidism may not require treatment, while others may need to take thyroid hormone replacement therapy to prevent the progression of hypothyroidism. The exact treatment will depend on the person’s symptoms and other health conditions. It also has Diagnosis code for hypothyroidism icd 10.

How to protect ourself from Hypothyroidism?

Icd 10 code that represents Hypothyroidism can be caused by a number of factors, including genetics, autoimmune disorders, and radiation exposure. To protect yourself, you can take the following steps:

Maintain a healthy diet:– Eating a balanced diet that includes foods rich in iodine, such as seafood and dairy products, can help keep your thyroid healthy.

Manage stress:– Chronic stress can impact thyroid function, so it’s important to find healthy ways to manage stress levels, such as exercise, meditation, or therapy.

Avoid exposure to radiation:– Limit your exposure to radiation from medical procedures, such as X-rays, as well as environmental sources like nuclear power plants.

Know your family history :–If you have a family history of hypothyroidism, be sure to talk to your doctor about your risk and what you can do to monitor your thyroid function.

Get regular check-ups :– Regular medical check-ups can help detect thyroid problems early, when they’re easiest to treat.

How is Hypothyroidism Treated ?

Hypothyroidism, a condition in which the thyroid gland does not produce enough hormones, is usually treated with hormone replacement therapy. icd 10 code The main treatment for hypothyroidism is to take a daily tablet of levothyroxine, which is a synthetic form of thyroid hormone.

This helps in restoring normal hormone levels in the body and reducing the symptoms. In addition to hormone replacement therapy, other treatments for hypothyroidism may include dietary changes, such as increasing iodine intake, and addressing underlying causes of the condition, such as autoimmune disorders.

It is important for individuals with hypothyroidism to have regular checkups with their healthcare provider so that their hormone levels can be monitored and their treatment can be adjusted as needed. It can take several weeks for hormone replacement therapy to start working and several months to find the right dose, so patience and persistence are key.

What are the 5 risk factors for hypothyroidism?

There are many risk factors for hypothyroidism, including:

● Women over the age of 60 are more likely to develop hypothyroidism.

● People with a family history of thyroid disease are at higher risk.

● Exposure to radiation, such as from X-rays or radiation therapy, can increase the risk of developing hypothyroidism.

● People whose thyroid gland has been removed or damaged are at higher risk of hypothyroidism.

● People with autoimmune diseases, such as type 1 diabetes or lupus, are at increased risk of hypothyroidism.

What is Hypothyroidism Hereditary?

Hypothyroidism is a condition in which the thyroid gland does not produce enough hormones. While this may be due to environmental factors, it may also have a genetic component. Family history and certain genetic mutations can increase the risk of developing icd 10 code hypothyroidism. However, it is not always inherited and can occur in people without a family history of the condition.


Icd 10 code Hypothyroidism, also known as underactive thyroid, is a condition in which the thyroid gland is not producing enough hormones to meet the body’s needs. This can cause a variety of symptoms, including fatigue, weight gain, etc. In this article, we have discussed in detail about icd 10 code for hypothyroidism.

In medical billing and coding, hypothyroidism is classified using the International Classification of Diseases, 10th Revision (ICD-10) code E03. The specific code used depends on the underlying cause of hypothyroidism as well as any associated conditions that may be present. For example, code E03.0 is used for primary hypothyroidism, while E03.1 is used for hypothyroidism secondary to pituitary or hypothalamic disease.

Through today’s post, we have tried to touch almost all the aspects of hypothyroidism. We have discussed all these topics in detail, what is hypothyroidism and what causes it, how it can be treated and how to protect yourself from hypothyroidism. It is important to seek medical attention if you experience symptoms of hypothyroidism, such as fatigue, weight gain, cold intolerance and constipation, should you consult a doctor.

Frequently Asked Questions:

Q1. What TSH ICD-10 code ?

Ans. The ICD-10 code for Thyroid-Stimulating Hormone (TSH) measurement is R94.5. It is used to describe elevated TSH levels in the blood, which can indicate an underactive thyroid (hypothyroidism). The ICD-10 code is used in medical billing and coding to accurately record and categorize a patient’s diagnosis for insurance and medical records purposes.
