Code Description

ICD-10 O23.32 is a billable code used to indicate a diagnosis of infections of other parts of urinary tract in pregnancy, second trimester.

Key Diagnostic Point:

Infections of the urinary tract during pregnancy can pose significant risks to both the mother and the developing fetus. O23.32 specifically refers to infections occurring in the second trimester, which is a critical period for fetal development. These infections may include pyelonephritis, cystitis, or urethritis, and can lead to complications such as preterm labor, low birth weight, and increased maternal morbidity. Symptoms may include dysuria, frequency, urgency, and flank pain. Diagnosis typically involves urinalysis and urine culture to identify the causative organism. Treatment often includes antibiotics that are safe for use during pregnancy, such as penicillins or cephalosporins, while avoiding those that may pose risks to fetal development. Close monitoring and follow-up are essential to ensure resolution of the infection and to mitigate any potential complications.
