ICD-10-CM K83.2
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

K83.2 is a billable ICD-10-CM diagnosis code for perforation of bile duct. 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 5 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.

Patient EducationClinical

Bile Duct Diseases

Your liver makes a digestive juice called bile. Your gallbladder stores it between meals. When you eat, your gallbladder pushes the bile into tubes called bile ducts. They carry the bile to your small intestine. The bile helps break down fat. It also helps the liver get rid of toxins and wastes.

Questions About K83.2Overview

What is the ICD-10 code for perforation of bile duct?

The ICD-10-CM code for perforation of bile duct is K83.2 (sometimes written as K832). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is K83.2 (Other diseases of biliary tract) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report perforation of bile duct on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does K83.2 group to?

When perforation of bile duct 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 K83.2 a CC or MCC?

CMS lists K83.2 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 5 closely related codes in its exclusion list.

Can K83.2 be reported with K91.5?

Not as a rule. The Excludes1 note at K83, which applies to K83.2, lists "postcholecystectomy syndrome (K91.5)". 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).
