About K86.89
K86.89 is the ICD-10-CM diagnosis code for other specified diseases of pancreas. It belongs to category K86 (other diseases of pancreas), 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.
Within K86.8, choose K86.89 (Other specified diseases of pancreas) only when documentation doesn't support a more specific option: Exocrine pancreatic insufficiency (K86.81).
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 438 (Disorders of Pancreas Except Malignancy with MCC, relative weight 1.5765), DRG 439 (Disorders of Pancreas Except Malignancy with CC, relative weight 0.8402) and DRG 440 (Disorders of Pancreas Except Malignancy without CC/MCC, relative weight 0.5965), 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 was added in FY2017, effective October 1, 2016.
Before ICD-10, this condition was coded in ICD-9-CM as 577.8 (other specified diseases of pancreas).
