Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Hypostatic bronchopneumonia
- Passive pneumonia
Other codes that can never be billed with J18.2
These codes carry an Excludes1 note pointing at J18.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading J18.2 alone.
Risk adjustment
J18.2 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.
Medicare coverage
J18.2 is named in 13 Medicare coverage policies — 13 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
