VA Disability Rating for Hepatitis B: Tiers, Evidence, and Appeals

The VA disability rating for hepatitis B runs from 0 percent to 100 percent under Diagnostic Code 7345, and in 2026 that translates to monthly compensation between $180.42 at the 10 percent level and $3,938.58 at 100 percent for a veteran with no dependents.¹² Where you land on that scale depends on how much the disease disrupts daily life, whether you need ongoing medication, and what kind of antiviral therapy your treatment requires. Before any rating attaches, though, you have to show that your hepatitis B is connected to your military service.

The Rating Tiers Under Diagnostic Code 7345

The VA overhauled its digestive-system rating criteria in a final rule that took effect on May 19, 2024.³ Under the current version of 38 CFR § 4.114, hepatitis B is graded on the progression of chronic liver disease, the medication required to control it, and a defined set of symptoms.¹

0 percent — A documented history of liver disease with no current symptoms. This rating produces no monthly payment but preserves service connection.
20 percent — Chronic liver disease with at least one of intermittent fatigue, malaise, anorexia, hepatomegaly, or pruritus.
40 percent — Progressive chronic liver disease requiring continuous medication, with minor weight loss and at least two symptoms from a list that includes daily fatigue, malaise, anorexia, hepatomegaly, pruritus, and arthralgia.
60 percent — The same picture as 40 percent, but with substantial weight loss.
100 percent — Progressive chronic liver disease requiring both parenteral antiviral therapy and parenteral immunomodulatory therapy such as interferon. The 100 percent rate continues for six months after treatment ends, then a mandatory VA examination sets the ongoing rating.

If your claim was pending before May 19, 2024, or you are seeking an increase for a period before that date, the earlier criteria — which turned on “incapacitating episodes” and included a 10 percent tier — can still apply to that timeframe.⁴

Getting Service Connection for Hepatitis B

The VA will not rate the condition until you have established service connection. That takes three pieces: a current diagnosis, an in-service event or exposure that could have caused the infection, and a medical opinion linking the two.⁵ Hepatitis B is not on any VA presumptive list. In fact, the presumptive schedule mentions it only as a disqualifier: liver cancer is presumptive for atomic veterans exposed to ionizing radiation, but not if hepatitis B or cirrhosis is indicated.⁶p>

Exposure Routes the VA Recognizes

The most familiar pathway involves jet injector guns, used across the military for mass vaccinations from the 1950s through the late 1990s. The devices could carry blood between shots, and a CDC investigation documented a 24 percent acute hepatitis B infection rate among people injected with a contaminated jet injector, against zero percent among those who received standard syringe injections.⁷ Wiping the nozzle with alcohol did not deactivate the virus. The VA has acknowledged that transmission through jet injectors is “biologically plausible,” a position first stated in VBA Fast Letter 04-13 (June 2004) and later folded into the Adjudication Manual.⁸

Combat exposure is another recognized risk factor. A study in Clinical Gastroenterology and Hepatology found that combat-zone service and being wounded in combat are independently associated with hepatitis B exposure, likely from contact with infected blood during battlefield care or casualty handling.⁹ Universal hepatitis B vaccination for all U.S. service members did not begin until after 2000, so anyone who served earlier had no vaccine-based protection.

Other accepted risk factors include blood transfusions (particularly before 1992, when screening was less rigorous), health care duties involving blood exposure, tattoos or body piercings with non-sterile equipment, and high-risk contact while stationed where the virus is endemic.¹⁰

The Nexus Letter

A nexus letter from a qualified physician is usually the piece of evidence that decides the claim. The doctor needs to identify the specific in-service risk factor, explain how hepatitis B can stay subclinical with normal liver enzymes for decades, and address any competing post-service risk factors. In one Board of Veterans’ Appeals decision, private physician letters carried substantial weight because they identified the exposure, applied expert knowledge about the disease’s long latency, and gave a reasoned rebuttal to a conflicting VA opinion.⁵ When the evidence for and against is roughly even, the VA must resolve reasonable doubt in the veteran’s favor.

What Happens at the C&P Exam

Once a claim is filed, the VA schedules a Compensation and Pension exam using the “Hepatitis, Cirrhosis and Other Liver Conditions Disability Benefits Questionnaire.” The examiner reviews your medical history, current symptoms, and lab results.¹¹

The examiner is specifically looking for the symptoms that drive the rating tiers: fatigue (intermittent or daily), malaise, anorexia, hepatomegaly, pruritus, arthralgia, and weight loss measured against your baseline. They also record whether you are on continuous medication or on parenteral antiviral and immunomodulatory therapy. Lab studies (AST, ALT, alkaline phosphatase, bilirubin, INR, creatinine) and imaging or biopsy results are reviewed.¹¹ The examiner also documents how the disease affects your ability to stand, walk, lift, and sit at work. That functional-impact section matters not only for the initial rating but for any later unemployability claim.

Evidence That Moves the Rating Up

Board decisions show what the VA actually credits. In one case, the Board granted 100 percent based on consistent reports of daily, chronic, and debilitating fatigue, malaise, nausea, vomiting, right upper quadrant pain, diarrhea, and weight loss; the veteran had already been granted Total Disability based on Individual Unemployability specifically for hepatitis B.¹²

In another case, the Board denied 100 percent even though private doctors said the veteran had “near constant debilitating symptoms” going back years. Actual treatment records from that period described the veteran as “doing well” with “no symptoms,” and the Board gave the longitudinal records more weight than the retrospective statements.¹³ The lesson is that steady documentation of symptoms as they occur, in your ongoing treatment notes, outweighs summaries produced later.

Lay evidence helps too. Personal statements, buddy letters, and statements from spouses or coworkers can be submitted on VA Form 21-10210, and they land best when they describe firsthand observations of specific symptoms — fatigue, pain, weight loss, limits on daily activity — rather than general conclusions.¹⁴ Lay evidence supplements medical records; it does not replace them.

When Hepatitis B Progresses

Hepatitis B can advance to more serious liver disease. The VA rates those complications under separate diagnostic codes, subject to the anti-pyramiding rule that bars counting the same symptom twice.¹

Cirrhosis

Cirrhosis is rated under DC 7312, using the Model for End-Stage Liver Disease (MELD) score or, if no MELD score is available, symptomatology. Ratings run from 0 percent (asymptomatic with a history of liver disease) to 100 percent, which requires either a MELD score of 15 or higher, or continuous daily debilitating symptoms with generalized weakness plus at least one serious complication such as ascites, hepatic encephalopathy, variceal hemorrhage, or hepatorenal syndrome.¹ Liver dysfunction must be confirmed by laboratory studies, imaging, or biopsy.

Liver Cancer

Hepatocellular carcinoma occurring with cirrhosis is rated under DC 7343 as a malignant neoplasm of the digestive system. It carries an automatic 100 percent rating during active disease and treatment. Six months after treatment ends, a mandatory examination rates the residuals.¹ If the cancer developed because of service-connected hepatitis B, it can be claimed as a secondary condition, and a nexus opinion is almost always required.

Secondary Mental Health Conditions and the Pyramiding Rule

Depression comes up often alongside hepatitis B claims because of the disease’s chronic course and effect on quality of life.⁴ A psychiatric condition can be claimed as secondary to hepatitis B if you have a current diagnosis and a medical opinion linking it to the service-connected liver disease.¹⁵ The limit is 38 CFR § 4.14, which prohibits pyramiding. A 2025 Board decision denied a separate rating for chronic fatigue secondary to hepatitis B, holding that fatigue was already compensated within the hepatitis B rating, particularly where the 100 percent rating rested on “near-constant debilitating symptoms” including daily fatigue.¹⁶ A genuinely separate diagnosis can be rated alongside hepatitis B; a symptom of the disease cannot be broken out into its own rating.

Reaching 100 Percent Pay Without a 100 Percent Schedular Rating

If hepatitis B keeps you from holding steady work, you may qualify for Total Disability based on Individual Unemployability even at a lower schedular rating. TDIU pays at the 100 percent rate — $3,938.58 per month for a single veteran in 2026 — while your official rating stays where it is.¹⁴ The standard schedular path requires one service-connected disability rated 60 percent or higher, or two or more with a combined rating of at least 70 percent and one condition rated at least 40 percent. You also must show you cannot maintain substantially gainful employment because of the service-connected condition. Marginal work — odd jobs or work below the federal poverty threshold — does not disqualify you. Extraschedular TDIU is available where the disability shows an exceptional pattern such as frequent hospitalization or marked interference with employment. The application is VA Form 21-8940, backed by medical evidence.

Veterans already rated at 100 percent may qualify for Special Monthly Compensation on top of the standard rate. SMC-S (housebound) applies when a veteran has a single disability rated at 100 percent plus a separate service-connected disability rated at least 60 percent, or when the veteran is substantially confined to the home due to service-connected conditions; the 2026 rate for a single veteran is $4,408.53 per month. SMC-L (aid and attendance) pays $4,900.83 per month and is available to veterans who are permanently bedridden or need daily help with basic activities such as eating, dressing, and bathing.¹⁷ SMC turns on functional limitation, not on any particular diagnosis.

If the Decision Is Wrong

Veterans who disagree with a rating decision have three review lanes, and they generally must be filed within one year of the decision letter.¹⁸

Supplemental Claim (VA Form 20-0995) is the path when you have new and relevant evidence the VA has not yet seen. Disability compensation supplemental claims were averaging about 61 days to complete as of early 2026.¹⁹
Higher-Level Review puts the existing evidence in front of a senior reviewer to check for error. No new evidence is allowed, but you can request an informal conference to point out specific factual or legal problems. VA targets 125 days.²⁰
Board Appeal sends the case to a Veterans Law Judge. It allows the most thorough reconsideration and typically takes the longest.

If a supplemental claim is denied, you can move to higher-level review, a Board appeal, or file another supplemental claim with additional evidence.

2026 Monthly Compensation

The 2026 rates took effect December 1, 2025. For a veteran with no dependents, the schedule pays $180.42 at 10 percent, $356.66 at 20 percent, $552.47 at 30 percent, $1,132.90 at 50 percent, and $3,938.58 at 100 percent; rates at 30 percent and above rise with a spouse, children, or dependent parents.² A veteran rated at 100 percent with a spouse and no other dependents receives $4,158.17 per month.
