K82.2 is a billable ICD-10-CM diagnosis code for perforation of gallbladder. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 444 through 446. As a secondary diagnosis, it counts as a major complication or comorbidity (MCC) and places an inpatient stay in the highest severity level of its MS-DRG family. It does not count, however, when the principal diagnosis is one of 10 closely related codes. Coders also document this condition as injury of bile duct. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Biliary tract disease and Gastrointestinal and biliary perforation.

Gallbladder Diseases
Your gallbladder is a pear-shaped organ under your liver. It stores bile, a fluid made by your liver to digest fat. As your stomach and intestines digest food, your gallbladder releases bile through a tube called the common bile duct. The duct connects your gallbladder and liver to your small intestine.

Questions About K82.2Overview
What is the ICD-10 code for perforation of gallbladder?
The ICD-10-CM code for perforation of gallbladder is K82.2 (sometimes written as K822). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is K82.2 (Other diseases of gallbladder) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report perforation of gallbladder on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does K82.2 group to?
When perforation of gallbladder is the principal diagnosis on an inpatient stay, it groups to MS-DRG 444, 445, 446, with relative weights from 0.8121 to 1.6662 depending on complications. Higher weights mean higher Medicare reimbursement.
Is K82.2 a CC or MCC?
CMS lists K82.2 as an MCC (major complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it places the inpatient stay in the highest-weighted DRG of its severity family. It does not count when the principal diagnosis is one of the 10 closely related codes in its exclusion list.
Can K82.2 be reported with K82.A2?
Not as a rule. The Excludes1 note on K82.2 lists "Perforation of gallbladder in cholecystitis (K82.A2)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
