ICD-10 code for pancreas pseudocyst

The ICD-10-CM code for pancreas pseudocyst is K86.3 (Pseudocyst of pancreas).

Within K86 (other diseases of pancreas), K86.3 is specifically for pseudocyst of pancreas. Related codes cover alcohol-induced chronic pancreatitis (K86.0), other chronic pancreatitis (K86.1), cyst of pancreas (K86.2), other specified diseases of pancreas (K86.8) and disease of pancreas, unspecified (K86.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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), DRG 440 (Disorders of Pancreas Except Malignancy without CC/MCC, relative weight 0.5965), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 07 (Diseases and Disorders of the Hepatobiliary System and Pancreas) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
