A diverticulitis VA rating falls under Diagnostic Code (DC) 7327 in 38 CFR 4.114 at 0%, 20%, or 30%, depending on whether you required hospital admission in the past 12 months and whether severe complications occurred. At Rank and Pay, we track how the Department of Veterans Affairs (VA) evaluates gastrointestinal conditions. Diverticulosis refers to small pouches pushing outward through weak spots in the wall of the large intestine, while diverticulitis occurs when those pouches become inflamed or infected.

Diverticulitis VA Rating Schedule Under DC 7327

The Department of Veterans Affairs evaluates diverticulitis and diverticulosis under Diagnostic Code (DC) 7327 in 38 CFR 4.114. The rating schedule establishes three distinct evaluation tiers based on clinical findings, treatment methods, and inpatient stays.

The following comparison table outlines how the three evaluation levels under DC 7327 differ in criteria and documentation requirements:

Rating Level Core Diagnostic Criteria Hospitalization Required Required Clinical Evidence
0% Asymptomatic, or symptoms controlled through diet and medication No Outpatient treatment notes and pharmacy records
20% Abdominal distress, fever, and leukocytosis without structural complications Yes (1 or more times in past 12 months) Inpatient admission summaries and lab tests showing elevated white blood cells
30% Abdominal distress, fever, leukocytosis, plus at least one named complication Yes (1 or more times in past 12 months) Inpatient admission records documenting hemorrhage, obstruction, abscess, peritonitis, or perforation

The Hospitalization Requirement for Compensable Disability Ratings

Inpatient hospital admission records form the dividing line between a non-compensable 0% rating and a compensable 20% or 30% rating under DC 7327. The 20% description turns on hospitalization, so confirm with VA how an outpatient or same-day emergency room visit is treated.

To secure a 20% evaluation, your medical documentation must prove that you were formally admitted to a hospital inpatient unit during the 12 months preceding your claim or examination. That stay must document three specific findings: abdominal distress, fever, and leukocytosis. Leukocytosis means an elevated white blood cell count confirmed by laboratory blood tests. If any of these three elements is missing from your admission records, VA will rate the condition at 0%. If your hospital stay occurred 13 months ago rather than within the past 12 months, the schedule requires a 0% rating.

Complications That Trigger a 30 Percent Evaluation

A 30% rating requires an inpatient admission in the past 12 months with abdominal distress, fever, and leukocytosis, plus documentation of at least one structural complication. The rating schedule recognizes five specific complications: hemorrhage, obstruction, abscess, peritonitis, and perforation.

The regulation ties the 30% level to hospitalization together with one of these complications.

Surgical Resections and Large Intestine Diagnostic Codes

When severe diverticular disease leads to surgery such as a partial colectomy or colostomy, VA applies a specific rating comparison rule. Rating specialists evaluate the condition under either DC 7327 or DC 7329, which covers resection of the large intestine.

Under 38 CFR 4.114, VA must assign whichever diagnostic code results in the higher evaluation for your impairment. If your residual symptoms or digestive complications under DC 7329 provide a higher rating than the hospitalization criteria under DC 7327, VA assigns the DC 7329 code. Review your surgical records and pathology reports carefully to understand whether bowel resection residuals provide a better evaluation than your recent hospital admission records.

Establishing Service Connection for Diverticular Disease

Before VA considers rating percentages, you must establish service connection under VA eligibility rules. There are two primary pathways to establish service connection for diverticular disease.

The first path is direct service connection. You need three distinct elements: a current clinical diagnosis of diverticulitis or diverticulosis, an in-service illness, event, or injury documented in your military records, and a medical link connecting the two. You can review the basic evidence standards in our guide on service connection requirements. A formal medical assessment, detailed in our nexus letter guide, helps link your current gastrointestinal diagnosis to your active duty service.

The second path is secondary service connection under 38 CFR 3.310. If an established service-connected disability or the medications prescribed for it causes or aggravates your diverticular disease, you can file a secondary claim. A clinician can provide a supporting nexus opinion. Review our guide on secondary conditions to learn how medical opinions must connect primary and secondary disabilities.

What to Expect at a Diverticular Disease C&P Exam

When you file a claim, VA usually schedules a Compensation and Pension (C&P) examination.

The clinician conducts an interview regarding your gastrointestinal history, current medications, dietary changes, and functional limitations. Review our C&P exam tips before attending your evaluation. The examiner will verify whether you were admitted to a hospital inpatient ward during the prior 12 months. Bring copies of your hospital discharge summaries, complete blood count lab results showing white blood cell counts, and pharmacy lists. Describe how your flare-ups restrict your daily activities, including dietary adjustments and work interruptions.

Records Comparison Exercise for Your Diverticulitis VA Rating

Comparing your personal medical records against the rating schedule helps clarify which evaluation band aligns with your documentation. The following scenarios demonstrate how the rating criteria apply to different evidence profiles:

Combining a Diverticulitis VA Rating With Other Disability Ratings

VA does not add disability percentages together using standard arithmetic. Instead, VA combines ratings using a non-additive calculation based on your remaining whole-person efficiency.

For example, if you receive a 20% evaluation for diverticulitis and hold a separate 30% rating for a back disability, your combined rating is 44%, which VA rounds down to 40%. You can test different percentages with our free VA disability rating calculator to determine how an individual gastrointestinal rating changes your overall monthly compensation. Once VA issues a decision, review our walkthrough on reading a rating decision to verify that the regional office assigned the correct diagnostic code and effective date.

Steps to File a Diverticular Disease Claim

Organizing your medical records before submitting your claim reduces administrative delays. Follow these steps to file your application:

  1. Submit an intent to file online to lock in your potential effective date while you collect documentation.
  2. Gather hospital admission records, physician discharge summaries, and emergency department records covering all treatment in the past 12 months.
  3. Obtain complete blood count laboratory reports documenting leukocytosis recorded during any hospital stays.
  4. Collect pharmacy records and treatment progress notes showing ongoing prescription medications and dietary management.
  5. Assemble your service treatment records showing in-service symptoms, or obtain an independent medical nexus opinion linking your condition to your military service or an existing service-connected disability.
  6. Submit your completed application online through the official VA disability claim portal.

Who This Evaluation Guide Is Not For and Rating Schedule Updates

This guide is not for veterans who experience abdominal pain but do not have a formal clinical diagnosis of diverticulitis or diverticulosis from a licensed medical provider. If you have uncharacterized digestive symptoms, consult a physician to establish a definitive diagnosis before filing, because VA requires documented clinical evidence to grant service connection.

What would change our answer is a regulatory update to 38 CFR Part 4 by the Department of Veterans Affairs. VA periodically updates its disability evaluation schedules for the digestive system. If VA amends DC 7327 to remove the strict hospitalization rule or adjust the 12-month lookback period, rating determinations would change accordingly. Confirm current regulatory text directly with VA or an accredited representative before filing.

Gather your inpatient admission summaries from the past 12 months to verify your records against DC 7327 before submitting your diverticulitis VA rating application.
