J68Respiratory conditions due to inhalation of chemicals, gases, fumes and vapors

Non-billable headerICD-10-CM

J68 is a non-billable header ICD-10-CM code for respiratory conditions due to inhalation of chemicals, gases, fumes and vapors. It cannot be billed on its own: choose one of the more specific child codes below.

Code first

The underlying condition must be sequenced before this code.

Use additional code

Add a secondary code to capture the detail described below.

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

Other codes that can never be billed with J68

These codes carry an Excludes1 note pointing at J68. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading J68 alone.

  • J18Pneumonia, unspecified organism
  • J39Other diseases of upper respiratory tract
  • J40Bronchitis, not specified as acute or chronic
  • J67Hypersensitivity pneumonitis due to organic dust
  • J68.4Chronic respiratory conditions due to chemicals, gases, fumes and vapors
  • J81Pulmonary edema

Risk adjustment

J68 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead J68

7 child codes. Green means billable.
