Code Description

ICD-10 O23.30 is a billable code used to indicate a diagnosis of infections of other parts of urinary tract in pregnancy, unspecified trimester.

Key Diagnostic Point:

Infections of the urinary tract during pregnancy can pose significant risks to both the mother and fetus. This code specifically refers to infections occurring in parts of the urinary tract that are not classified under other specific codes. Common infections include cystitis and pyelonephritis, which can lead to complications such as preterm labor, low birth weight, and increased maternal morbidity. The diagnosis is often made based on clinical symptoms such as dysuria, frequency, urgency, and flank pain, along with urinalysis and culture results. Treatment typically involves antibiotics, which must be chosen carefully to ensure safety for both the mother and the developing fetus. Certain antibiotics, such as nitrofurantoin and amoxicillin, are generally considered safe during pregnancy, while others may pose risks. Close monitoring and follow-up are essential to prevent recurrent infections and manage any complications that may arise.

  • Need for accurate trimester specification when coding
  • Potential overlap with other urinary tract infection codes
  • Consideration of antibiotic safety and maternal health

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings
  • Failure to specify the trimester of pregnancy
  • Incorrect coding of related urinary tract conditions
  • Lack of follow-up documentation for recurrent infections
