B06Rubella [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.

  • M01Direct infections of joint in infectious and parasitic diseases classified elsewhere
  • M02Postinfective and reactive arthropathies
  • 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

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 to one of these instead B06

3 child codes. Green means billable.
