About coding colonic pseudo-obstruction intestine
The ICD-10-CM code for colonic pseudo-obstruction intestine is K59.81 (Ogilvie syndrome).
Within K59.8 (other specified functional intestinal disorders), K59.81 is specifically for Ogilvie syndrome. Related codes cover other specified functional intestinal disorders (K59.89).
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 391 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders with MCC, relative weight 1.2392) and DRG 392 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCC, relative weight 0.7645), in MDC 06 (Diseases and Disorders of the Digestive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
