About J68.1

J68.1 is the ICD-10-CM diagnosis code for pulmonary edema due to chemicals, gases, fumes and vapors. It belongs to category J68 (respiratory conditions due to inhalation of chemicals, gases, fumes and vapors), block J60-J70 (lung diseases due to external agents) 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 J68 (respiratory conditions due to inhalation of chemicals, gases, fumes and vapors), J68.1 is specifically for pulmonary edema due to chemicals, gases, fumes and vapors. Related codes cover bronchitis and pneumonitis due to chemicals, gases, fumes and vapors (J68.0), upper respiratory inflammation due to chemicals, gases, fumes and vapors, not elsewhere classified (J68.2), other acute and subacute respiratory conditions due to chemicals, gases, fumes and vapors (J68.3), chronic respiratory conditions due to chemicals, gases, fumes and vapors (J68.4), other respiratory conditions due to chemicals, gases, fumes and vapors (J68.8) and unspecified respiratory condition due to chemicals, gases, fumes and vapors (J68.9).

Don't report J68.1 together with the conditions in its Excludes1 note: pulmonary edema (acute) (chronic) NOS (J81.-).

Code first: (T51-T65) to identify cause.

Use an additional code to identify associated respiratory conditions, such as: acute respiratory failure (J96.0-).

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 189 (Pulmonary Edema and Respiratory Failure, relative weight 1.2108), 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 506.1 (acute pulmonary edema due to fumes and vapors).
