About coding Oddi's sphincter spasm
The ICD-10-CM code for Oddi's sphincter spasm is K83.4 (Spasm of sphincter of Oddi).
Within K83 (other diseases of biliary tract), K83.4 is specifically for spasm of sphincter of Oddi. Related codes cover cholangitis (K83.0), obstruction of bile duct (K83.1), perforation of bile duct (K83.2), fistula of bile duct (K83.3), biliary cyst (K83.5), other specified diseases of biliary tract (K83.8) and disease of biliary tract, unspecified (K83.9).
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 444 (Disorders of the Biliary Tract with MCC, relative weight 1.6665), DRG 445 (Disorders of the Biliary Tract with CC, relative weight 1.0872) and DRG 446 (Disorders of the Biliary Tract without CC/MCC, relative weight 0.8124), 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.
