About J67.1

J67.1 is the ICD-10-CM diagnosis code for Bagassosis. It belongs to category J67 (hypersensitivity pneumonitis due to organic dust), 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 J67 (hypersensitivity pneumonitis due to organic dust), J67.1 is specifically for Bagassosis. Related codes cover Farmer's lung (J67.0), Bird fancier's lung (J67.2), Suberosis (J67.3), Maltworker's lung (J67.4), Mushroom-worker's lung (J67.5), Maple-bark-stripper's lung (J67.6), air conditioner and humidifier lung (J67.7), hypersensitivity pneumonitis due to other organic dusts (J67.8) and 1 more.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 196 (Interstitial Lung Disease with MCC, relative weight 1.8336), DRG 197 (Interstitial Lung Disease with CC, relative weight 0.9492) and DRG 198 (Interstitial Lung Disease without CC/MCC, relative weight 0.7259), 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 495.1 (Bagassosis).
