Evidence Checklist: Diverticulitis

CT abdomen/pelvis confirming diverticulitis episodesCritical

CT scan with contrast documenting pericolic inflammation, diverticula with wall thickening, pericolic fat stranding, or abscess formation during acute diverticulitis attacks.

Colonoscopy confirming diverticulosis and ruling out malignancyCritical

Colonoscopy report performed after resolution of acute episode, documenting diverticulosis extent, luminal complications, and absence of colorectal cancer.

Nexus opinion linking diverticulitis to service ("at least as likely as not")Critical

A medical opinion connecting diverticulitis to service-related dietary factors (low-fiber MRE diet), chronic constipation, or in-service abdominal trauma predisposing to diverticular development.

Hospitalization records for acute diverticulitis episodes

Inpatient records for acute diverticulitis admissions including CT findings, antibiotic treatment, IV nutrition, and any abscess drainage procedures.

Surgical records for colon resection or ostomy (if applicable)

Operative reports for sigmoid colectomy, Hartmann's procedure, or colostomy formation for complicated diverticulitis — these may support additional ratings.

Incapacitating episode frequency documentationCritical

Medical records or personal log tracking acute attacks requiring hospitalization or bed rest per year — the central rating factor for intestinal conditions.

A written statement from someone who can describe observable symptoms and how your condition affects daily life.

Personal statement describing symptoms and functional impact

Your own written account of how this condition affects your daily activities, work, and relationships. Describe your worst days.
