Code Description

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

Key Diagnostic Point:

Infections of the bladder during pregnancy, commonly referred to as urinary tract infections (UTIs), can pose significant health risks to both the mother and the developing fetus. These infections are characterized by the presence of bacteria in the urinary tract, leading to symptoms such as dysuria, frequency, urgency, and suprapubic pain. In pregnant women, the physiological changes, including increased urinary stasis and hormonal alterations, can predispose them to UTIs. The condition can occur in any trimester, but it is particularly concerning in the first and third trimesters due to the potential for complications such as pyelonephritis, preterm labor, and low birth weight. Diagnosis typically involves urinalysis and urine culture, and treatment often includes antibiotics that are safe for use during pregnancy. It is crucial for healthcare providers to monitor and manage UTIs effectively to prevent adverse outcomes.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of obstetric conditions, including UTIs. This specificity helps in better tracking of maternal health outcomes and improves the quality of care provided to pregnant patients.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of obstetric conditions, including UTIs. This specificity helps in better tracking of maternal health outcomes and improves the quality of care provided to pregnant patients.
