Colon Cancer VA Disability Ratings and Service Connection

Colon cancer is recognized (and compensated) as a VA disability when it is connected to military service. If you have qualifying service, you are entitled to monthly payments, healthcare priority, and other VA benefits. For many Gulf War-era and post-9/11 veterans with qualifying toxic exposure service, colon cancer is a VA presumptive condition under the PACT Act.

VA assigns a 100% rating to colon cancer while it is active and during treatment. Six months after treatment ends, VA conducts a mandatory examination to determine whether the 100% rating should continue or whether residuals should be rated instead.

How Can You Get VA Disability for Colon Cancer?

1. PACT Act presumptive service connection. This is the easiest route for many Gulf War-era and post-9/11 veterans. If you served in a qualifying location during the required time period and have colon cancer, rectal cancer, or another covered gastrointestinal cancer, VA should presume the condition is service connected.
2. Direct service connection. Veterans who do not qualify under the PACT Act can still prove colon cancer is related to military service. This usually requires evidence of an in-service exposure and a medical nexus opinion.
3. Secondary service connection. Colon cancer may also be claimed through secondary service connection if it was caused or aggravated by an already service-connected condition. This may apply when a service-connected digestive disorder, inflammatory bowel disease, or cancer treatment contributed to the colon cancer.

You do not need to know which theory applies before you file. Filing early protects your effective date and potential back pay. If you have a diagnosis, the next step is filing VA Form 21-526EZ and submitting the strongest evidence available.

When Is Colon Cancer a VA Presumptive Condition?

A presumptive condition means VA does not require you to prove the cancer was caused by military service. You still need to prove two things:

1. A current diagnosis
2. Qualifying service in a covered location during a covered time period

The PACT Act and Colon Cancer

The PACT Act is the most important development for many colon cancer claims. It created a presumption for several cancers linked to burn pits and airborne hazards, including gastrointestinal cancer of any type. Colon cancer and rectal cancer (collectively called colorectal cancer) fall under that umbrella.

Veterans who served in covered locations during the required timeframes are generally presumed exposed to burn pits or airborne hazards. They do not need to prove they personally worked near a burn pit.

Qualifying Era and Locations

For Gulf War-era service beginning August 2, 1990, qualifying locations include:

• Bahrain
• Iraq
• Kuwait
• Oman
• Qatar
• Saudi Arabia
• Somalia
• the United Arab Emirates
• the airspace above these locations

For service beginning September 11, 2001, qualifying locations include:

• Afghanistan
• Djibouti
• Egypt
• Jordan
• Lebanon
• Syria
• Uzbekistan
• Yemen
• the airspace above these locations

Qualifying Cancer Diagnoses

The law uses the phrase gastrointestinal cancer of any type. That can include colon cancer, colorectal cancer, rectal cancer, anal cancer, stomach cancer, esophageal cancer, pancreatic cancer, liver cancer, gallbladder cancer, and other GI tract malignancies.

A pathology report or physician diagnosis is usually the key medical evidence. Precancerous colon polyps alone do not qualify as PACT Act gastrointestinal cancer, but they may matter in a separate colon polyps claim or as part of the medical timeline.

Timing of the Claim

There is no deadline to file an initial PACT Act claim, but earlier filing matters. Your effective date usually controls how much back pay VA may owe you.

If VA denied your colon cancer claim before the PACT Act and you have qualifying Gulf War-era or post-9/11 service, you can file a Supplemental Claim.

How to Prove Colon Cancer Is Related to Military Service

Not every colon cancer claim fits the PACT Act. Veterans outside the PACT Act window still have possible service connection pathways.

Agent Orange Exposure

Colon cancer is not presumptive for Agent Orange exposure. Vietnam-era veterans usually need a direct service connection theory or a secondary service connection theory.

A direct claim should include a medical nexus opinion from a qualified physician, preferably an oncologist or gastroenterologist. The opinion should discuss the exposure history, risk factors, pathology, and why service exposure is at least as likely as not connected to the cancer.

See how to claim colon cancer from Agent Orange exposure.

Camp Lejeune Water Contamination

Veterans who served at Camp Lejeune or MCAS New River for at least 30 total days between August 1, 1953, and December 31, 1987, may qualify for certain presumptions. However, colon cancer is not on VA’s Camp Lejeune presumptive condition list.

That does not mean the claim is impossible. Camp Lejeune veterans may still pursue direct service connection with a medical nexus opinion. Some may also explore separate legal rights under the Camp Lejeune Justice Act.

Other Toxic Exposures

• asbestos
• ionizing radiation
• JP-4, JP-5, or JP-8 jet fuel
• diesel exhaust
• PFAS or firefighting foam
• solvents, degreasers, or industrial chemicals
• occupational chemical exposure tied to MOS or duty assignment

How the VA Rates Colon Cancer

VA rates colon cancer under 38 CFR § 4.114, Diagnostic Code 7343, which covers malignant neoplasms of the digestive system, excluding skin growths.

When colon cancer is active, VA assigns a 100% disability rating. The 100% rating applies while the cancer is active and during treatment such as surgery, radiation, chemotherapy, or another therapeutic procedure.

The 6-Month Mark and Mandatory Reexamination

Six months after treatment ends, VA should schedule a mandatory medical examination. This exam determines whether the cancer has recurred, metastasized, or left lasting residuals.

If there is recurrence or metastasis, the 100% rating can continue. If the cancer is no longer active, VA rates the condition based on residuals. The residuals review is where many ratings get reduced, so veterans should document every post-treatment symptom before the reexamination.

VA Ratings for Colon Cancer Residuals

Colon cancer residuals can affect digestion, bowel control, nutrition, nerves, scars, and mental health. After the active-cancer rating period ends, VA should rate each distinct residual when the evidence supports it.

This can include bowel dysfunction, sphincter loss, resection of the large intestine, adhesions, ostomy complications, scars, chemotherapy neuropathy, anemia, or depression.

Resection of the Large Intestine

Many veterans undergo partial or total colectomy. VA may rate those residuals under DC 7329, depending on the type of resection and the remaining symptoms.

Symptoms may include diarrhea, urgency, abdominal pain, malabsorption, weight changes, or complications from reconnection of the bowel.

Colostomy or Ileostomy

A temporary or permanent colostomy or ileostomy can significantly affect daily life. VA may rate these issues under digestive-system codes such as DC 7329, DC 7330, or DC 7332, depending on the main disability.

The strongest evidence includes surgical reports, ostomy clinic records, supply use, skin complications, leakage history, and statements describing daily management.

Impaired Sphincter Control

Rectal cancer surgery and pelvic treatment may cause impaired sphincter control. VA rates sphincter impairment under DC 7332, with ratings based on severity, leakage, pad use, and loss of control. Document frequency, urgency, leakage, pad changes, nighttime symptoms, accidents, and whether the problem affects work or travel.

Adhesions and Abdominal Surgery Residuals

Abdominal surgery can cause adhesions, chronic pain, bowel obstruction symptoms, or pulling sensations. VA may rate adhesions under DC 7301 when the evidence supports persistent symptoms. Surgical reports, emergency room records, imaging, and statements describing pain or obstruction-like symptoms can help.

Functional Bowel Symptoms

Some veterans have chronic diarrhea, constipation, urgency, cramping, or alternating bowel patterns after treatment. VA may rate these symptoms under digestive-system criteria such as DC 7319 when appropriate. A bowel log can help show frequency and severity.

Surgical Scars

Colon cancer surgery often leaves abdominal scars. Report scar pain, tenderness, breakdown, pulling, numbness, and limitation of movement: painful, unstable, or large scars may qualify for separate ratings under VA’s skin rating criteria. See VA ratings for scars.

Chemotherapy Neuropathy

Chemotherapy can cause peripheral neuropathy in the hands, feet, arms, or legs. VA rates neuropathy under the nerve affected and the severity of impairment. Medical evidence may include oncology notes, neurology records, nerve testing, and statements about balance, grip strength, walking, or fine motor problems.

Mental Health Conditions

A cancer diagnosis and treatment can contribute to depression, anxiety, adjustment disorder, or post-treatment fear of recurrence. If a mental health condition is caused or aggravated by service-connected colon cancer, it may be claimed through secondary service connection.

How Rectal and Colorectal Cancers Are Rated

If your medical reports say colorectal cancer or rectal cancer instead of colon cancer, that does not mean you are outside the PACT Act or VA rating framework.

Colorectal cancer is an umbrella term that includes cancers of the colon and rectum. VA generally uses the same active-cancer rating framework for colon and rectal cancers because both fall under malignant neoplasms of the digestive system.

That means active colorectal cancer is generally rated at 100% during active disease and treatment, followed by a post-treatment review. After that review, VA rates any remaining residuals based on the affected body system.

The main difference is often the type of residuals. Rectal cancer may be more likely to cause sphincter damage, bowel leakage, pelvic radiation effects, urinary problems, sexual dysfunction, or permanent colostomy.

Colon cancer may more often involve colectomy residuals, bowel frequency changes, adhesions, anemia, ostomy issues, or chemotherapy-related neuropathy.

Can You Get a Colon Polyps VA Rating?

Colon polyps are generally benign, but some are precancerous and removed during colonoscopy. You can get a colon polyps VA rating if VA service connects them to military service and it may help document the disease timeline if cancer develops later.

VA typically rates benign digestive system growths under Diagnostic Code 7344, based on the main residuals.

• Asymptomatic polyps removed during colonoscopy may receive a 0% rating if service connected.
• Polyps causing chronic bowel symptoms may be rated based on the dominant digestive symptoms.
• Polyps requiring bowel surgery may be rated under the residual surgical code.
• Polyps that progress to colon cancer are rated under DC 7343 once cancer is diagnosed.

How to Win VA Disability for Colon Cancer

A strong colon cancer claim connects the diagnosis to the correct service connection pathway and documents the full rating picture. The goal is to show VA why the cancer is service connected and how the cancer or treatment still affects you.

Step 1: Confirm Qualifying Service

For PACT Act claims, gather records showing service in a covered location during the required period. This may include DD-214, deployment orders, personnel records, pay records, unit records, or performance reports.

For non-presumptive claims, gather evidence showing the actual exposure. This may include MOS records, ship records, base records, safety reports, environmental reports, or buddy statements.

Step 2: Document the Diagnosis

VA needs medical proof of the cancer diagnosis. Submit:

• pathology reports
• colonoscopy reports
• surgical reports
• oncology notes
• imaging records
• chemotherapy or radiation summaries
• staging information

Step 3: File VA Form 21-526EZ

File the claim as soon as possible after diagnosis. Effective dates matter, and delay can reduce back pay.

Include the cancer and any secondary conditions or residuals, such as neuropathy, scars, bowel dysfunction, erectile dysfunction, depression, anemia, or ostomy complications.

Step 4: Prepare for the C&P Exam

The C&P exam may decide both service connection and rating. Bring records and be clear about symptoms.

Do not only tell the examiner the cancer is in remission. Explain what remains: bowel urgency, leakage, pain, fatigue, anemia, neuropathy, scars, ostomy management, or work limits.

Step 5: Claim Secondary Conditions

Secondary conditions should be claimed separately when they are caused or aggravated by the colon cancer or its treatment. Examples include:

• depression or anxiety
• erectile dysfunction secondary to pelvic surgery or radiation
• urinary problems secondary to pelvic treatment
• peripheral neuropathy secondary to chemotherapy
• surgical scars secondary to colon cancer surgery
• anemia secondary to chronic GI bleeding or treatment

Survivor Benefits for Colon Cancer

If a veteran dies from service-connected colon cancer, surviving family members may qualify for VA survivor benefits.

The most important benefit is usually Dependency and Indemnity Compensation (DIC). DIC is a tax-free monthly benefit for eligible survivors when the veteran’s death resulted from a service-connected condition.

Survivors may also qualify for:

• Accrued benefits
• Survivors Pension
• CHAMPVA
• Chapter 35 Dependents’ Educational Assistance
• Burial and memorial benefits

If colon cancer appears as the primary cause of death in the death certificate, the evidence is stronger. If it appears as a contributing condition, DIC may still be possible.

If colon cancer is not listed on the death certificate, survivors may need medical records or a doctor’s opinion explaining how the cancer or its treatment substantially contributed to death.

Why Colon Cancer Claims Get Denied and How to Fix Them

Colon cancer claims are often denied because the evidence does not match the correct service connection path. The fix depends on why VA denied the claim.

VA Cannot Confirm PACT Act Qualifying Service

VA may deny the claim if it cannot verify service in a covered location during the required time period. You’ll have to submit deployment orders, pay records, unit histories, buddy statements, or other proof showing service in the qualifying area during the required period.

The Claim Was Denied Before the PACT Act

Some veterans filed before August 10, 2022, and VA denied the claim under older rules.

Rectify this by filing a Supplemental Claim. Hill & Ponton can handle the appeal on your behalf, our VA-accredited lawyers specialize in winning denied VA disability claims, with no upfront costs.

The Claim Lacks a Current Diagnosis

VA needs a confirmed diagnosis, not only symptoms or suspicion of cancer. To fix this, submit pathology reports, oncology records, colonoscopy findings, or surgical records confirming colon cancer or colorectal cancer.

VA Drops the Rating After Treatment

VA may reduce the rating after treatment if the exam does not capture residuals. Appeal the rating and submit evidence of ongoing residuals such as bowel dysfunction, ostomy management, neuropathy, anemia, scars, or mental health symptoms.

A Vietnam-Era Veteran Filed Under Agent Orange

Colon cancer is not currently presumptive for Agent Orange exposure. Pursue direct service connection with a nexus opinion or a secondary service connection theory when supported by medical evidence.

Colon cancer claims do become complicated for veterans trying to handle them alone if the VA denies service connection, misapplies the PACT Act, or doesn’t fully evaluate residuals.
