    • Viral hepatitis (B15-B19)
      • Unspecified viral hepatitis (B19)

B19.21 is a billable diagnosis code used to specify a medical diagnosis of unspecified viral hepatitis c with hepatic coma. The code B19.21 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code B19.21 might also be used to specify conditions or terms like hepatic coma due to viral hepatitis c.

Unspecified diagnosis codes like B19.21 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Information for Patients


Coma

A coma is a deep state of unconsciousness. An individual in a coma is alive but unable to move or respond to his or her environment. Coma may occur as a complication of an underlying illness, or as a result of injuries, such as brain injury.

A coma rarely lasts more than 2 to 4 weeks. The outcome for coma depends on the cause, severity, and site of the damage. People may come out of a coma with physical, intellectual, and psychological problems. Some people may remain in a coma for years or even decades. For those people, the most common cause of death is infection, such as pneumonia.

Hepatitis C

What is hepatitis C?

Hepatitis is inflammation of the liver. Inflammation is swelling that happens when tissues of the body are injured or infected. Inflammation can damage organs.

There are different types of hepatitis. One type, hepatitis C, is caused by the hepatitis C virus (HCV). Hepatitis C can range from a mild illness lasting a few weeks to a serious, lifelong illness.

Hepatitis C can be acute or chronic:

How is hepatitis C spread?

Hepatitis C spreads through contact with the blood of someone who has HCV. This contact may be through

Before 1992, hepatitis C was also commonly spread through blood transfusions and organ transplants. Since then, there has been routine testing of the U.S. blood supply for HCV. It is now very rare for someone to get HCV this way.

Who is at risk for hepatitis C?

You are more likely to get hepatitis C if you

If you are at high risk for hepatitis C, your health care provider will likely recommend that you get tested for it.

What are the symptoms of hepatitis C?

Most people with hepatitis C have no symptoms. Some people with acute hepatitis C do have symptoms within 1 to 3 months after they are exposed to the virus. These symptoms may include

If you have chronic hepatitis C, you probably will not have symptoms until it causes complications. This can happen decades after you were infected. For this reason, hepatitis C screening is important, even if you have no symptoms.

What other problems can hepatitis C cause?

Without treatment, hepatitis C may lead to cirrhosis, liver failure, and liver cancer. Early diagnosis and treatment of hepatitis C can prevent these complications.

How is hepatitis C diagnosed?

Health care providers diagnose hepatitis C based on your medical history, a physical exam, and blood tests.

If you do have hepatitis C, you may need additional tests to check for liver damage. These tests may include other blood tests, an ultrasound of the liver, and a liver biopsy.

What are the treatments for hepatitis C?

Treatment for hepatitis C is with antiviral medicines. They can cure the disease in most cases.

If you have acute hepatitis C, your health care provider may wait to see if your infection becomes chronic before starting treatment.

If your hepatitis C causes cirrhosis, you should see a doctor who specializes in liver diseases. Treatments for health problems related to cirrhosis include medicines, surgery, and other medical procedures. If your hepatitis C leads to liver failure or liver cancer, you may need a liver transplant.

Can hepatitis C be prevented?

There is no vaccine for hepatitis C. But you can help protect yourself from hepatitis C infection by
