About Q39.2

Q39.2 is the ICD-10-CM diagnosis code for congenital tracheo-esophageal fistula without atresia. It belongs to category Q39 (congenital malformations of esophagus), block Q38-Q45 (other congenital malformations of the digestive system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Q39, choose Q39.2 (Congenital tracheo-esophageal fistula without atresia) 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 stenosis and stricture of esophagus (Q39.3), esophageal web (Q39.4), congenital dilatation of esophagus (Q39.5), congenital diverticulum of esophagus (Q39.6), other congenital malformations of esophagus (Q39.8) and congenital malformation of esophagus, unspecified (Q39.9).

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 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.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 750.3 (tracheoesophageal fistula, esophageal atresia and stenosis).
