Z22.330 — Carrier of Group B streptococcus
Z22.330 is a billable, specific ICD-10-CM code for carrier of group b streptococcus. 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.
- Carrier of streptococcus group B (GBS) complicating pregnancy, childbirth and the puerperium (O99.82-)
Other codes that can never be billed with Z22.330
These codes carry an Excludes1 note pointing at Z22.330. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z22.330 alone.
- O99.82Streptococcus B carrier state complicating pregnancy, childbirth and the puerperium
Risk adjustment
Z22.330 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.
