B06 — Rubella [German measles]

Non-billable headerICD-10-CM

B06 is a non-billable header ICD-10-CM code for rubella [german measles]. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

congenital rubella (P35.0)

Other codes that can never be billed with B06

These codes carry an Excludes1 note pointing at B06. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading B06 alone.

G02Meningitis in other infectious and parasitic diseases classified elsewhere
G05Encephalitis, myelitis and encephalomyelitis in diseases classified elsewhere
G99.8Other specified disorders of nervous system in diseases classified elsewhere
J17Pneumonia in diseases classified elsewhere
M01Direct infections of joint in infectious and parasitic diseases classified elsewhere
M02Postinfective and reactive arthropathies

Risk adjustment

B06 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 history

B06 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead B06

3 child codes. Green means billable.
