ICD 10 Code For Fever – R50.9

When you have a fever, your body temperature is elevated above its normal temperature. In most people, a fever is considered to be a body temperature of 100.4°F (38°C) or higher. A fever can be caused by many different things, such as infection, illness, or injury. There are many different types of fevers, and each has its own icd 10 code.

Here are some of the most common types of fevers: -A low-grade fever is a body temperature that is slightly elevated above normal. It is usually not harmful and does not require treatment. -A high-grade fever is a body temperature that is significantly elevated above normal. It can be dangerous and requires immediate medical attention. -A recurrent fever is a fever that comes and goes over a period of time. It may be caused by an underlying medical condition and requires treatment. -A remittent fever is a fever that fluctuates between high and low temperatures over a period of time. It may be caused by an underlying medical condition and requires treatment.

What are the Different Types of Fevers?

There are three main types of fever:

  1. Low-grade fever: This is a mild fever that doesn’t require treatment. A low-grade fever is usually caused by a viral infection, such as the common cold or the flu.
  2. High-grade fever: This is a more serious type of fever that requires treatment. A high-grade fever can be caused by bacterial infections, such as pneumonia or meningitis.
  3. Fever of unknown origin: This is a fever that can’t be attributed to any specific cause. Fever of unknown origin is often seen in people with cancer or other chronic illnesses.

Symptoms of Fever

There are a few different symptoms that may be indicative of a fever, which is why it is important to consult with a medical professional if you are experiencing any of the following:

-A temperature reading of 100.4 degrees Fahrenheit or higher using a thermometer
-Persistent feeling of warmth
-Flushed appearance
-Muscle aches and pains
-Loss of appetite
-Fatigue or weakness

Causes of Fever

Fever is a common symptom of many different conditions. It occurs when the body’s temperature rises above its normal range. Fever can be caused by infections, inflammatory diseases, autoimmune diseases, and cancer. It can also be caused by certain medications, such as steroids and chemotherapy drugs.

Infections are the most common cause of fever. They can be caused by bacteria, viruses, or fungi. The body responds to these invaders by releasing chemicals that raise the temperature, in an effort to kill the infection.

Inflammatory diseases such as arthritis and lupus can also cause fever. In these conditions, the body’s immune system attacks healthy tissue, causing inflammation. The resulting increase in temperature is thought to help fight the disease.

Autoimmune diseases like Graves’ disease can also lead to fever. In these conditions, the body produces antibodies that attack healthy tissues. This can cause inflammation and lead to a rise in temperature.

Cancer can also cause fever, though this is less common. Cancer cells release substances that can trigger a febrile response from the body. Medications used to treat cancer, such as chemotherapy drugs, may also cause fever as a side effect.

Treatment for Fever

There are a variety of treatments available for fever. The most common and effective treatment is ibuprofen. This medication can be taken orally or rectally. Ibuprofen works by reducing inflammation and pain.

Other medications that can be used to treat fever include acetaminophen, naproxen, and aspirin. Acetaminophen is typically used for children and infants. Naproxen is a non-steroidal anti-inflammatory drug (NSAID) that is used for adults. Aspirin is also an NSAID, but it should not be given to children or adolescents due to the risk of Reye’s syndrome.

If the fever is very high, the individual may need to be hospitalized so that they can be monitored closely and treated with intravenous (IV) fluids and medications. In some cases, surgery may be necessary to remove the source of the infection.

When to See a Doctor for Fever

If you have a fever, it is important to seek medical attention. A fever is a sign that your body is fighting an infection, and it can be a serious health concern. If you have a fever, you should see a doctor to find out the cause and to get treatment.


The ICD 10 code for fever is R50.0. Fever is a common health condition caused by a variety of things, such as infection, inflammation, or heat exposure. While most fevers go away on their own, some can last for days or even weeks and may require medical treatment. If you think you have a fever, it’s important to see a doctor to make sure that there isn’t an underlying cause that needs to be treated.
