Code Description

ICD-10 O23.23 is a billable code used to indicate a diagnosis of infections of urethra in pregnancy, third trimester.

Key Diagnostic Point:

Infections of the urethra during the third trimester of pregnancy can pose significant risks to both the mother and the fetus. These infections are often caused by bacteria that can ascend from the lower urinary tract, leading to conditions such as cystitis or pyelonephritis. Symptoms may include dysuria, increased urinary frequency, and suprapubic pain. In pregnant women, the physiological changes, such as increased blood volume and altered immune response, can make them more susceptible to urinary tract infections (UTIs). Prompt diagnosis and treatment are crucial to prevent complications such as preterm labor or low birth weight. Antibiotic therapy is typically initiated based on culture results, with a focus on agents that are safe for use during pregnancy. Commonly prescribed antibiotics include nitrofurantoin and amoxicillin, which are generally considered safe in the third trimester. However, caution is advised, and the choice of antibiotic should always consider the potential risks and benefits for both the mother and the fetus.
