Evidence Checklist: Cholecystitis
DC 7314
Significant gaps — claim likely to be denied or underrated
Specialist Opinion (Highest Value)
Abdominal ultrasound showing gallstones, wall thickening, or pericholecystic fluidCritical
Ultrasound report documenting cholelithiasis, gallbladder wall thickening (>3 mm), pericholecystic fluid, or positive sonographic Murphy's sign consistent with cholecystitis.
HIDA scan (hepatobiliary scintigraphy) documenting gallbladder function
HIDA scan results showing gallbladder ejection fraction — a low ejection fraction (<35%) confirms chronic cholecystitis (biliary dyskinesia), especially when ultrasound is inconclusive.
Nexus opinion linking cholecystitis to service ("at least as likely as not")Critical
A medical opinion connecting cholecystitis to service-related factors including rapid weight changes during service, high-fat military diet, or service-connected metabolic conditions.
Treatment Records
Labs during acute episodes (WBC, bilirubin, liver function, lipase)
Lab results from acute cholecystitis episodes showing leukocytosis, elevated bilirubin (if common duct involved), and liver enzyme elevation consistent with biliary inflammation.
Treatment records (hospitalization, cholecystectomy, ERCP)
Records documenting antibiotic treatment, laparoscopic or open cholecystectomy, ERCP for choledocholithiasis, and post-operative course.
Lay Statements & Personal Documentation

Medical records or personal log documenting recurrent biliary colic attacks, ER visits, and dietary restrictions required to manage symptoms.
Buddy statement from spouse, family, or fellow service member
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.
Disability Benefits Questionnaire (DBQ)
Completed DBQ Gallbladder and Pancreas ConditionsCritical
Standardized form capturing cholecystitis diagnosis, imaging results, treatment history, and functional impact.
Service Records
Service treatment records (STRs)Critical
Military medical records showing in-service treatment, complaints, or injuries related to this condition.
