About J04.11

J04.11 is the ICD-10-CM diagnosis code for acute tracheitis with obstruction. It belongs to category J04 (acute laryngitis and tracheitis), block J00-J06 (acute upper respiratory infections) and chapter 10 (diseases of the respiratory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within J04.1 (acute tracheitis), J04.11 is specifically for acute tracheitis with obstruction. Related codes cover without obstruction (J04.10).

Use an additional code (B95-B97) to identify infectious agent.

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 202 (Bronchitis and Asthma with CC/MCC, relative weight 0.9474) and DRG 203 (Bronchitis and Asthma without CC/MCC, relative weight 0.6512), in MDC 04 (Diseases and Disorders of the Respiratory 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 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 464.11 (acute tracheitis with obstruction).
