Code Description

ICD-10 O23.93 is a billable code used to indicate a diagnosis of unspecified genitourinary tract infection in pregnancy, third trimester.

Key Diagnostic Point:

Genitourinary tract infections (UTIs) are common during pregnancy, particularly in the third trimester, due to physiological changes that occur in the urinary system. These infections can lead to significant complications if left untreated, including preterm labor, low birth weight, and increased risk of maternal morbidity. 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 nitrofurantoin or amoxicillin, while avoiding those that may pose risks to the fetus. It is crucial for healthcare providers to monitor the patient closely for any signs of complications, such as pyelonephritis, which may require hospitalization and intravenous antibiotics. Proper coding of this condition is essential for accurate billing and to ensure that the patient receives appropriate care throughout their pregnancy.

Complexity Factors

  • Variability in symptoms and presentation of genitourinary infections.
  • Need for accurate documentation of the infection type and treatment plan.
  • Differentiation between acute and chronic infections.
  • Potential for complications that may require additional coding.

Audit Risk Factors

  • Inadequate documentation of symptoms and treatment.
  • Failure to specify the type of infection.
  • Misclassification of the infection severity.
  • Lack of follow-up documentation for treatment efficacy.
