What This Code Means
O23.32 is the ICD-10-CM diagnosis code for infections of other parts of urinary tract in pregnancy, second trimester. A bacterial or fungal infection affecting parts of the urinary system (such as the ureters or urethra) during the second three months of pregnancy. O23.32 sits in the ICD-10-CM chapter for pregnancy, childbirth and the puerperium (o00-o9a), within the section covering other maternal disorders predominantly related to pregnancy (o20-o29).
O23.32 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Confirm documentation explicitly states second trimester or weeks 14-27 of pregnancy.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for O23.32 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Confirm documentation explicitly states second trimester or weeks 14-27 of pregnancy
