Code Description

ICD-10 O23.3 is a billable code used to indicate a diagnosis of infections of other parts of urinary tract in pregnancy.

Key Diagnostic Point:

Infections of the urinary tract during pregnancy can significantly impact maternal and fetal health. O23.3 specifically refers to infections that occur in parts of the urinary tract other than the bladder and kidneys, such as the urethra or ureters. These infections can lead to complications such as pyelonephritis, preterm labor, and low birth weight. Symptoms may include dysuria, frequency, urgency, and suprapubic 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 and cephalosporins, while avoiding those that may pose risks to the fetus. Close monitoring and follow-up are essential to ensure resolution of the infection and to prevent recurrence, as untreated urinary tract infections can lead to serious complications for both mother and child.
