K87Disorders of gallbladder, biliary tract and pancreas in diseases classified elsewhere

K87 is the ICD-10-CM diagnosis code for disorders of gallbladder, biliary tract and pancreas in diseases classified elsewhere. It belongs to block K80-K87 (disorders of gallbladder, biliary tract and pancreas) and chapter 11 (diseases of the digestive system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Don't report K87 together with the conditions in its Excludes1 note: cytomegaloviral pancreatitis (B25.2), mumps pancreatitis (B26.3), syphilitic gallbladder (A52.74), syphilitic pancreas (A52.74) and 2 more.

Code first: underlying disease.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 444 (Disorders of the Biliary Tract with MCC, relative weight 1.6665), DRG 445 (Disorders of the Biliary Tract with CC, relative weight 1.0872) and DRG 446 (Disorders of the Biliary Tract without CC/MCC, relative weight 0.8124), in MDC 07 (Diseases and Disorders of the Hepatobiliary System and Pancreas), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is a manifestation code, so it describes the effect of an underlying disease and can't be the principal diagnosis. Code the underlying condition first.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 576.8 (other specified disorders of biliary tract) and 577.8 (other specified diseases of pancreas).
