Written on A98 — Other viral hemorrhagic fevers, not elsewhere classified

chikungunya hemorrhagic fever (A92.0)
dengue hemorrhagic fever (A91)

Other codes that can never be billed with A98.5

These codes carry an Excludes1 note pointing at A98.5. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A98.5 alone.

Risk adjustment

A98.5 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.
