2025 ICD-10-CM Diagnosis Code B19.20

Approximate Synonyms

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

Clinical Classification

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

MS-DRG Mapping for ICD-10-CM Code B19.20

Diagnosis-Related Groups (DRGs) are used to classify hospital cases for billing and healthcare management. They help standardize how hospitals and other providers are reimbursed for inpatient care. Patients are grouped based on their principal diagnosis into broader categories called Major Diagnostic Categories (MDCs).

Once assigned to a DRG, the hospital receives a set payment for the patient’s care, regardless of the actual services provided. This fixed rate is intended to cover the typical cost of treating patients within that group. The payment amount depends on the DRG's relative weight, which reflects the expected complexity and cost of care based on the severity of the patient’s condition.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V42.0 applicable from 10/01/2024 through 09/30/2025.

Convert B19.20 to ICD-9-CM

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

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:

• Acute hepatitis C is a short-term infection. The symptoms can last up to 6 months. Sometimes your body is able to fight off the infection and the virus goes away. But for most people, an acute infection leads to chronic infection.
• Chronic hepatitis C is a long-lasting infection. If it is not treated, it can last for a lifetime and cause serious health problems, including liver damage, cirrhosis (scarring of the liver), liver cancer, and even death.

How is hepatitis C spread?

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

• Sharing drug needles or other drug materials with someone who has HCV. In the United States, this is the most common way that people get hepatitis C.
• Getting an accidental stick with a needle that was used on someone who has HCV. This can happen in health care settings.
• Being tattooed or pierced with tools or inks that were not sterilized after being used on someone who has HCV.
• Having contact with the blood or open sores of someone who has HCV.
• Sharing personal care items that may have come in contact with another person's blood, such as razors or toothbrushes.
• Being born to a mother with HCV.
• Having unprotected sex with someone who has HCV.

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 more likely to get hepatitis C?

You are more likely to get hepatitis C if you:

• Have injected drugs
• Had a blood transfusion or organ transplant before July 1992
• Have hemophilia and received clotting factor before 1987
• Have been on kidney dialysis
• Have been in contact with blood or infected needles at work
• Have had tattoos or body piercings
• Have worked or lived in a prison
• Were born to a mother with hepatitis C
• Have HIV
• Have had more than one sex partner in the last 6 months
• Have had a sexually transmitted infection (STI)
• Are a man who has had sex with men (MSM)

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:

• Dark yellow urine
• Fatigue
• Fever
• Gray- or clay-colored stools
• Joint pain
• Loss of appetite
• Nausea and/or vomiting
• Pain in your abdomen (belly)
• Jaundice (yellowish eyes and skin)

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?

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 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:

• Not sharing drug needles or other drug materials.
• Wearing gloves if you have to touch another person's blood or open sores.
• Making sure your tattoo artist or body piercer uses sterile tools and unopened ink.
• Not sharing personal items such toothbrushes, razors, or nail clippers.
• Using a latex condom during sex. If your or your partner is allergic to latex, you can use polyurethane condoms.
