B10.0 — Other human herpesvirus encephalitis

Non-billable headerICD-10-CM

B10.0 is a non-billable header ICD-10-CM code for other human herpesvirus encephalitis. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

herpes encephalitis NOS (B00.4)
herpes simplex encephalitis (B00.4)
human herpesvirus encephalitis (B00.4)
simian B herpes virus encephalitis (B00.4)

Other codes that can never be billed with B10.0

These codes carry an Excludes1 note pointing at B10.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading B10.0 alone.

Risk adjustment

B10.0 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.

Code to one of these instead B10.0
