ICD-10 code for esophagus duplication

The ICD-10-CM code for esophagus duplication is Q39.8 (Other congenital malformations of esophagus).

Within Q39, choose Q39.8 (Other congenital malformations of esophagus) only when documentation doesn't support a more specific option: atresia of esophagus without fistula (Q39.0), atresia of esophagus with tracheo-esophageal fistula (Q39.1), congenital tracheo-esophageal fistula without atresia (Q39.2), congenital stenosis and stricture of esophagus (Q39.3), esophageal web (Q39.4), congenital dilatation of esophagus (Q39.5), congenital diverticulum of esophagus (Q39.6) and congenital malformation of esophagus, unspecified (Q39.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" 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 368 (Major Esophageal Disorders with MCC, relative weight 1.6433), DRG 369 (Major Esophageal Disorders with CC, relative weight 0.9922) and DRG 370 (Major Esophageal Disorders without CC/MCC, relative weight 0.6744), 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.
