About coding Pancreolithiasis
The ICD-10-CM code for Pancreolithiasis is K86.89 (Other specified diseases of pancreas).
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.
