ICD-10 code for gastroschisis

The ICD-10-CM code for gastroschisis is Q79.3 (Gastroschisis).

Within Q79 (congenital malformations of musculoskeletal system, not elsewhere classified), Q79.3 is specifically for gastroschisis. Related codes cover congenital diaphragmatic hernia (Q79.0), other congenital malformations of diaphragm (Q79.1), Exomphalos (Q79.2), prune belly syndrome (Q79.4), other congenital malformations of abdominal wall (Q79.5), Ehlers-Danlos syndromes (Q79.6), other congenital malformations of musculoskeletal system (Q79.8) and congenital malformation of musculoskeletal system, unspecified (Q79.9).

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 393 (Other Digestive System Diagnoses with MCC, relative weight 1.5881), DRG 394 (Other Digestive System Diagnoses with CC, relative weight 0.9228), DRG 395 (Other Digestive System Diagnoses without CC/MCC, relative weight 0.6382), 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 06 (Diseases and Disorders of the Digestive System) 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.
