Code first
The underlying condition must be sequenced before this code.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Post-acute sequela of COVID-19
Notes
Additional guidance from the ICD-10-CM tabular list.
- This code enables establishment of a link with COVID-19.
- This code is not to be used in cases that are still presenting with active COVID-19. However, an exception is made in cases of re-infection with COVID-19, occurring with a condition related to prior COVID-19.
Other codes that can never be billed with U09.9
These codes carry an Excludes1 note pointing at U09.9. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading U09.9 alone.
- Z86.16Personal history of COVID-19
Risk adjustment
U09.9 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
U09.9 is named in 7 Medicare coverage policies — 7 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
