About coding colon ptosis
The ICD-10-CM code for colon ptosis is K63.4 (Enteroptosis).
Within K63 (other diseases of intestine), K63.4 is specifically for Enteroptosis. Related codes cover abscess of intestine (K63.0), perforation of intestine (nontraumatic) (K63.1), fistula of intestine (K63.2), ulcer of intestine (K63.3), polyp of colon (K63.5), other specified diseases of intestine (K63.8) and disease of intestine, unspecified (K63.9).
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 393 (Other Digestive System Diagnoses with MCC, relative weight 1.5881), DRG 394 (Other Digestive System Diagnoses with CC, relative weight 0.9228) and DRG 395 (Other Digestive System Diagnoses without CC/MCC, relative weight 0.6382), 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.
