Care settings
How CMS programs treat this code. These are CMS claim edits and list entries, not coverage or eligibility rules.
Hospice: not accepted as primary
Not accepted as the principal diagnosis on a hospice claim (bill types 081x and 082x). The Integrated OCE returns an edit for this code.
Reason: Supplementary or additional code, not allowed as principal diagnosis.
Hospital MCC
Counts as a major complication or comorbidity (MCC) when reported as a secondary diagnosis on an inpatient claim. No principal diagnosis cancels it. Some MS-DRGs also ignore a CC or MCC that defines the DRG.

Further defines or gives examples of the content of the category.
- bronchopneumonia due to viruses other than influenza viruses
Inclusion terms
Conditions classified to this code.
- Pneumonia due to 2019 novel coronavirus (SARS-CoV-2)
- Pneumonia due to COVID-19
Notes
Also from chapter/block level (1 note)
- When a respiratory condition is described as occurring in more than one site and is not specifically indexed, it should be classified to the lower anatomic site (e.g. tracheobronchitis to bronchitis in J40).
