ICD-10 code for esophagus congenital diverticulum

The ICD-10-CM code for esophagus congenital diverticulum is Q39.6 (Congenital diverticulum of esophagus). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q39.6.

Within Q39 (congenital malformations of esophagus), Q39.6 is specifically for congenital diverticulum of esophagus. Related codes cover 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), other congenital malformations of esophagus (Q39.8) 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.
