Diverticulitis is rated by the VA under Diagnostic Code 7327, with three possible levels in 2026: 0%, 20%, or 30%. The rating depends almost entirely on whether you've been hospitalized for a flare-up in the past 12 months and whether that flare-up involved a serious complication like a perforation or abscess. Veterans whose diverticulitis is managed with diet and medication alone, without hospitalization, typically receive a 0% rating, which confirms service connection but pays no compensation on its own.
This guide breaks down exactly how each rating level works, what evidence the VA looks for, how diverticulitis interacts with other digestive conditions in your claim, and how to file or appeal.
What Is Diverticulitis and Why the VA Rates It Differently Now
Diverticulitis occurs when small pouches (diverticula) that form in the wall of the colon become inflamed or infected. It's distinct from diverticulosis, which is simply the presence of those pouches without active inflammation. Both conditions are rated under the same diagnostic code.
Effective May 19, 2024, the VA overhauled its digestive system rating schedule, including how diverticulitis and diverticulosis are evaluated. Before that update, digestive conditions like this were often rated by analogy to other codes, which produced inconsistent results. The current framework under DC 7327 is built around a single, objective question: has this condition required hospitalization, and if so, was there a serious complication?
VA Diverticulitis Rating Levels (Diagnostic Code 7327)
| Rating | Criteria |
|---|
| 30% | Hospitalization within the past 12 months for abdominal distress, fever, and leukocytosis (elevated white blood cell count), plus one or more serious complications: hemorrhage, obstruction, abscess, peritonitis, or perforation |
| 20% | Hospitalization within the past 12 months for abdominal distress, fever, and leukocytosis, without the serious complications listed above |
| 0% | Asymptomatic, or symptomatic diverticulitis/diverticulosis managed through diet and medication without hospitalization |
Notice there is no rating between 0% and 20%, and none between 20% and 30%. Diverticulitis under DC 7327 tops out at 30%. If your condition is severe enough to require a colectomy or colostomy, that surgical outcome is rated separately under Diagnostic Code 7329, which allows ratings from 10% up to 100% depending on how the surgery affects bowel function.
Why Hospitalization Is the Deciding Factor
The current rating schedule doesn't ask how often you experience abdominal pain or how many days of work you've missed. It asks specifically whether you were hospitalized for the condition in the 12 months before your VA exam or claim decision. This is a stricter evidentiary bar than some veterans expect. If your flare-ups are managed entirely through outpatient visits, antibiotics, or emergency room visits that stop short of admission, you may still land at 0%, even if the symptoms themselves are disruptive.
This makes documentation critical. If you are hospitalized for a diverticulitis flare, make sure your discharge paperwork clearly states the admission, the diagnosis, your white blood cell count, and any complications identified by your treating physician.
Grandfathering: What Happens If You Were Already Rated
Veterans who had an existing rating for diverticulitis or diverticulosis before the May 19, 2024 rule change are generally grandfathered in under whichever set of criteria, old or new, produces the higher rating. The VA cannot reduce a grandfathered rating simply because the new rules are stricter. A reduction can only happen if medical evidence shows sustained improvement measured against the criteria that were in effect when the rating was assigned.
If your claim was pending as of May 19, 2024, the VA is required to evaluate it under both the old and new criteria and apply whichever produces the higher outcome. If you believe your claim wasn't evaluated this way, that's a valid basis for a supplemental claim or appeal.
Combined Ratings: Diverticulitis, IBS, and Other Digestive Conditions
One rule trips up a lot of veterans filing digestive claims. Diagnostic codes 7301 through 7329 cover most of the gastrointestinal system, including diverticulitis (7327) and irritable bowel syndrome (7319). Under 38 CFR 4.114, the VA generally will not assign separate ratings for two or more conditions within that code range if they produce overlapping symptoms. Instead, the VA rates you once, under whichever diagnostic code reflects your predominant symptoms, to avoid what the regulation calls "pyramiding," or double-counting the same impairment.
In practice, this means you likely won't get a combined rating for diverticulitis plus IBS if both are causing similar abdominal symptoms. You will get one rating for the condition that best captures your overall disability picture. Conditions outside that code range, such as GERD, may still be rated separately since they aren't considered part of the same functional system in the same way.
Secondary Service Connection
Diverticulitis can sometimes be connected to service on a secondary basis, meaning it developed because of, or was aggravated by, a condition that's already service-connected. Veterans have successfully argued secondary connection in a few scenarios:
- Chronic stress and gut-brain axis disruption from service-connected PTSD or anxiety contributing to digestive dysfunction
- Long-term use of medications prescribed for a service-connected condition (such as NSAIDs or opioids) that affect bowel health
- Other service-connected GI conditions, like GERD or gastritis, that a physician links to the development of diverticulitis
Secondary claims require a nexus letter from a medical provider explicitly connecting the two conditions. A general statement that "stress can affect digestion" usually isn't enough. You need a doctor willing to state, to at least a 50% probability, that your service-connected condition caused or worsened your diverticulitis.
How to File a VA Claim for Diverticulitis
- Gather medical evidence. Collect hospital discharge summaries, colonoscopy or CT scan results, lab reports showing elevated white blood cell counts, and any surgical records.
- Get a diagnosis on record. Your claim needs a current diagnosis of diverticulitis or diverticulosis from a treating physician.
- Establish the service connection. For direct service connection, you need evidence linking the condition to an in-service event, injury, or exposure. For secondary connection, you need a nexus letter tying it to an existing service-connected condition.
- File your claim through VA.gov, by mail using VA Form 21-526EZ, or with help from an accredited Veterans Service Organization (VSO) representative.
- Attend your Compensation and Pension (C&P) exam. The VA examiner will review your hospitalization history and complication history over the past 12 months, so bring documentation with you or make sure it's already in your VA medical records.
- Wait for your decision. If you disagree with the rating assigned, you can file a Supplemental Claim with new evidence, request a Higher-Level Review, or appeal to the Board of Veterans' Appeals.
Increasing an Existing Rating
If your diverticulitis has worsened since your last rating decision, such as a new hospitalization or a complication that wasn't present before, you can file for an increased rating. The key is fresh medical evidence covering the 12 months before your new claim. A single ER visit without admission generally won't move you from 0% to 20%. A documented inpatient hospitalization with the required symptoms will.
TDIU and Diverticulitis
Because diverticulitis caps at 30% on its own, it's uncommon for this condition alone to prevent someone from working. However, if diverticulitis combines with other service-connected conditions to the point where you can't maintain substantially gainful employment, you may be eligible for Total Disability based on Individual Unemployability (TDIU), which pays at the 100% rate even if your combined schedular rating is lower.
Frequently Asked Questions
What is the highest VA disability rating for diverticulitis?
The highest schedular rating under Diagnostic Code 7327 is 30%. This requires hospitalization within the past 12 months plus a serious complication such as hemorrhage, obstruction, abscess, peritonitis, or perforation. If diverticulitis has progressed to the point of requiring a colectomy or colostomy, that outcome is rated separately under DC 7329, which can go as high as 100%.
Can I get a 0% rating and still receive VA disability pay?
A 0% rating confirms your diverticulitis is service-connected, but it does not add to your monthly compensation on its own. It can still matter for future claims, since it establishes the condition on record, and it can support secondary claims for related conditions down the line.
Does the VA require surgery to rate diverticulitis at 30%?
No. Surgery is not required for a 30% rating under DC 7327. What's required is hospitalization for a flare-up along with a documented complication like an abscess or perforation. If surgery does occur, such as a colectomy, it's typically rated separately and can produce a higher combined outcome.
Can I get separate ratings for diverticulitis and IBS?
Generally no. Diagnostic codes 7301 through 7329, which include both diverticulitis (7327) and IBS (7319), are treated as one functional system. The VA typically assigns a single rating based on your predominant symptoms rather than combining ratings for overlapping digestive conditions.
What happened to diverticulitis ratings in 2024?
Effective May 19, 2024, the VA updated its digestive system rating criteria across multiple diagnostic codes, including diverticulitis and diverticulosis under DC 7327. The new criteria focus specifically on hospitalization history and complications rather than more subjective symptom descriptions used previously. Veterans rated before that date are generally grandfathered under whichever criteria produce the higher rating.
How do I prove my diverticulitis is connected to my military service?
You need medical evidence linking your current diagnosis to an event, injury, exposure, or condition from your time in service, or to an already service-connected condition through secondary connection. This usually requires a nexus opinion from a physician stating it's at least as likely as not that your diverticulitis is related to your service or to a service-connected condition.
