Code Description

ICD-10 O23.11 is a billable code used to indicate a diagnosis of infections of bladder in pregnancy, first trimester.

Key Diagnostic Point:

Infections of the bladder, commonly referred to as urinary tract infections (UTIs), are prevalent during pregnancy, particularly in the first trimester. These infections can arise due to physiological changes such as increased urinary stasis and hormonal alterations that affect the urinary tract. Symptoms may include dysuria, frequency, urgency, and suprapubic pain. If left untreated, UTIs can lead to more severe complications, including pyelonephritis, which poses risks to both the mother and fetus. Diagnosis typically involves urinalysis and urine culture to identify the causative organism. Treatment is crucial and often involves antibiotics that are deemed safe for use during pregnancy. Commonly prescribed antibiotics include nitrofurantoin and amoxicillin, while certain medications like tetracyclines and fluoroquinolones are contraindicated due to potential teratogenic effects. Regular screening and prompt treatment of UTIs in pregnant women are essential to ensure maternal and fetal health.
