Which MS-DRGs does K82.2 group to?
K82.2 sits in MDC 07 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 444Disorders of the Biliary Tract with MCCmedical
- 445Disorders of the Biliary Tract with CCmedical
- 446Disorders of the Biliary Tract without CC/MCCmedical
As a secondary diagnosis, K82.2 is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together

- Perforation of gallbladder in cholecystitis (K82.A2)
Inclusion terms
Alternative wording in documentation that is classified to K82.2.
- Rupture of cystic duct or gallbladder
Excludes1 — never code together — inherited from K82
The conditions below can never be reported together with K82.2 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 11
The conditions below are not part of K82.2, but a patient may have both at the same time. When documentation supports it, K82.2 and the excluded code may both be reported.

- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
