About coding pancreas disease
The ICD-10-CM code for pancreas disease is K86.9 (Disease of pancreas, unspecified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K86.9.
Within K86, choose K86.9 (Disease of pancreas, unspecified) only when documentation doesn't support a more specific option: alcohol-induced chronic pancreatitis (K86.0), other chronic pancreatitis (K86.1), cyst of pancreas (K86.2), pseudocyst of pancreas (K86.3) and other specified diseases of pancreas (K86.8).
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.
