ICD-10 Code K82.A2 – Perforation of gallbladder in cholecystitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K82.A2 – Perforation of gallbladder in cholecystitis
What it is
This code identifies a gallbladder perforation that occurs as a complication of cholecystitis. Use it when the record clearly states perforation of the gallbladder with cholecystitis.
Clinical signs
Clinical features vary; refer to documentation. Findings may include acute abdominal pain, fever, localized tenderness, or imaging evidence of gallbladder wall disruption with surrounding inflammation.
When to use this code
Use K82.A2 when the provider documents perforation of the gallbladder in the setting of cholecystitis. This applies whether the perforation is suspected clinically or confirmed by imaging, surgery, or pathology, if documented that way.
Choose this code when the chart links the perforation to cholecystitis rather than to trauma or another cause. If the note is vague, check documentation before assigning the code.
Do not use for
Do not use this code for gallbladder perforation without cholecystitis, or when perforation is due to trauma, surgery, or another non-inflammatory cause. Check documentation.
Coding tip
Code the condition only when the provider explicitly connects the perforation to cholecystitis.
