Billable / specific codeICD-10-CM

O23.30 is a billable, specific ICD-10-CM code for infections of other parts of urinary tract in pregnancy, unspecified trimester. It is valid for submission on a claim.

Risk adjustment

O23.30 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.
