About coding Omphalomesenteric duct persistence
The ICD-10-CM code for Omphalomesenteric duct persistence is Q43.0 (Meckel's diverticulum (displaced) (hypertrophic)).
Within Q43 (other congenital malformations of intestine), Q43.0 is specifically for Meckel's diverticulum (displaced) (hypertrophic). Related codes cover Hirschsprung's disease (Q43.1), other congenital functional disorders of colon (Q43.2), congenital malformations of intestinal fixation (Q43.3), duplication of intestine (Q43.4), ectopic anus (Q43.5), congenital fistula of rectum and anus (Q43.6), persistent cloaca (Q43.7), other specified congenital malformations of intestine (Q43.8) and 1 more.
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 380 (Complicated Peptic Ulcer with MCC, relative weight 1.9245), DRG 381 (Complicated Peptic Ulcer with CC, relative weight 1.0838) and DRG 382 (Complicated Peptic Ulcer without CC/MCC, relative weight 0.7281), 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.
