ICD-10-CM Q32.0
CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

Q32.0 is a billable ICD-10-CM diagnosis code for congenital tracheomalacia. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 11 through 13, 154 through 156. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 18 closely related codes. The code is exempt from POA reporting. Coders also document this condition as congenital anomaly of tracheal cartilage. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Respiratory congenital malformations.

Is Q32.0 (Congenital malformations of trachea and bronchus) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report congenital tracheomalacia on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

CMS lists Q32.0 as a CC (complication or comorbidity) for FY 2026. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 18 closely related codes in its exclusion list.

Is Q32.0 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for congenital tracheomalacia on inpatient claims. The code appears in the Congenital malformations of the respiratory system (Q30-Q34) range of the CMS exempt list.
