B97.4 — Respiratory syncytial virus as the cause of diseases classified elsewhere
B97.4 is a billable, specific ICD-10-CM code for respiratory syncytial virus as the cause of diseases classified elsewhere. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
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.
- RSV as the cause of diseases classified elsewhere
Other codes that can never be billed with B97.4
These codes carry an Excludes1 note pointing at B97.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading B97.4 alone.
- B34Viral infection of unspecified site
Risk adjustment
B97.4 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
B97.4 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How B97.4 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to B97.4.
- Respiratory›syncytial virus, as cause of disease classified elsewhere
- Virus, viral›respiratory syncytial›as cause of disease classified elsewhere
- Infection, infected, infective›virus, viral NOS›respiratory syncytial›as cause of disease classified elsewhere
