About coding cytomegaloviral pancreatitis
The ICD-10-CM code for cytomegaloviral pancreatitis is B25.2 (Cytomegaloviral pancreatitis).
Within B25 (cytomegaloviral disease), B25.2 is specifically for cytomegaloviral pancreatitis. Related codes cover cytomegaloviral pneumonitis (B25.0), cytomegaloviral hepatitis (B25.1), other cytomegaloviral diseases (B25.8) and unspecified (B25.9).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" 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.
