What hepatitis B ICD codes can I use?

If you’re looking for hepatitis B ICD codes to use, we’d like you to know that there are eight that you can pick from:

B16.0 - Acute hepatitis B with delta-agent with hepatic coma: This ICD-10 code is meant to be used on a patient confirmed to have acute Hepatitis B with a delta-agent (Hepatitis D) and the patient is in a hepatic coma.
B16.1 - Acute hepatitis B with delta-agent without hepatic coma: This is the same as Item 1, but the patient is not in a hepatic coma this time.
B16.2 - Acute hepatitis B without delta-agent with hepatic coma: This is the same as Item 1, but this time, they don’t have a delta-agent (Hepatitis D), but they are in a hepatic coma.
B16.9 - Acute hepatitis B without delta-agent and without hepatic coma: This is the same as Item 3, but the patient is not in a hepatic coma this time.
B18.0 - Chronic viral hepatitis B with delta-agent: This ICD-10 code is meant to be used on a patient confirmed to have chronic Hepatitis B and is accompanied by a delta-agent (Hepatitis D).
B18.1 - Chronic viral hepatitis B without delta-agent: This is the same as Item 5, but there is no delta-agent this time.
B19.10 - Unspecified viral hepatitis B without hepatic coma: This is the same as all the other items, but this time, it’s not specified if the Hepatitis B is chronic or acute. The patient is not in a hepatic coma.
B19.11 - Unspecified viral hepatitis B with hepatic coma: This is the same as Item 7, but the patient has a hepatic coma this time.

Are these hepatitis B ICD codes billable?

Yes. All the aforementioned hepatitis B-related ICD-10 codes are valid and billable.

Clinical information about Hepatitis B:

Hepatitis B is a viral infection of the liver. Not only that, but it is also the most common liver viral infection, too. What it does is that it causes the liver to become inflamed.

There are two types of Hepatitis B, which you can see in the list of Hepatitis B-related ICD-10 codes listed above—acute and chronic. If a patient has Hepatitis B but loses it after a while, we refer to that as acute. If it sticks around for too long, even with minor symptoms, we refer to that as chronic.

Whether a patient has acute or chronic Hepatitis B, it should be addressed as soon as possible because, if left unchecked, it can lead to unwanted complications and spell doom for the patient.

What starts as inflammation can lead to the emergence of Hepatitis D (which amplifies the stress of the liver twofold), cirrhosis (scar tissue replaces healthy tissue in the liver), liver failure (both Hepatitis D and cirrhosis can lead to this), or even liver cancer.

Those with Hepatitis B will likely have the following symptoms:

They will feel weak and tired
They will feel pain in their abdomen and joints
They will lose their appetite, feel nauseated, and may even vomit
They will have jaundice and fever
Their urine will be darker, and their poop will have a light color
Swelling may occur in the belly, arms, and legs. The node may have fluid in it, too

Synonyms include:

Hepatic coma due to acute hepatitis B
Hepatic coma due to acute hepatitis B with delta agent
Hepatic coma due to viral hepatitis B
Hepatic coma due to viral hepatitis D
Chronic type B viral hepatitis
Chronic viral hepatitis B with hepatitis D
Chronic viral hepatitis D

Commonly asked questions

Yes, there are distinct codes. For acute hepatitis B with delta-agent, the ICD code is B16.0, while for acute hepatitis B without delta-agent, the code is B16.9. These specific codes ensure precise diagnosis recording and facilitate effective treatment planning.

Luckily, vaccines exist for Hepatitis B, which should lower the chance of them getting it. It’s best to discuss this with your patients and convince them to get vaccinated.

Depending on the severity, some conditions may resolve without treatment. Healthcare professionals typically administer IV fluids, IV nutrition, and pain relief for acute, severe cases. In chronic instances, the action involves immune modulators and oral anti-viral medication, complemented by suggested lifestyle adjustments like adhering to a balanced, low-fat, low-sugar diet and minimizing or ceasing alcohol consumption. Surgery becomes a consideration only in instances where the liver is irreparably damaged.
