Code Description

ICD-10 O23.13 is a billable code used to indicate a diagnosis of infections of bladder in pregnancy, third trimester.

Key Diagnostic Point:

Infections of the bladder, commonly referred to as urinary tract infections (UTIs), are prevalent during pregnancy, particularly in the third trimester. This condition arises due to physiological changes in the urinary tract, including increased urinary stasis and hormonal influences that can predispose pregnant individuals to infections. Symptoms may include dysuria, increased urinary frequency, urgency, and suprapubic pain. If left untreated, UTIs can lead to more severe complications such as pyelonephritis, which poses risks to both the mother and fetus. 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 contraindicated in pregnancy. Close monitoring and follow-up are essential to ensure resolution of the infection and to prevent recurrence.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between acute and chronic infections.
  • Understanding the implications of antibiotic safety in pregnancy.
  • Recognizing the potential for complications such as pyelonephritis.
  • Navigating documentation requirements for high-risk pregnancies.

Audit Risk Factors

  • Inadequate documentation of symptoms and treatment.
  • Failure to specify the trimester of pregnancy.
  • Misidentification of the infection type (e.g., cystitis vs. pyelonephritis).
  • Incorrect coding of antibiotic therapy.

Specialty Focus

Medical Specialties

Obstetrics and Gynecology

Documentation Requirements

Detailed documentation of symptoms, urinalysis results, and treatment plans is essential. Providers should also document any patient education regarding UTI prevention.

Common Clinical Scenarios

A pregnant patient presents with dysuria and increased urinary frequency; urinalysis confirms a UTI. Treatment with a safe antibiotic is initiated.

Billing Considerations

Coders must ensure that the documentation reflects the specific trimester and any complications that may arise.

Maternal-Fetal Medicine

Documentation Requirements

High-risk pregnancies require thorough documentation of maternal and fetal health, including any potential impacts of the infection.

Common Clinical Scenarios

A patient with a history of recurrent UTIs presents in the third trimester; close monitoring and tailored antibiotic therapy are necessary.

Billing Considerations

Consideration of the patient's overall health status and any comorbidities is crucial for accurate coding.

Coding Guidelines

Inclusion Criteria

Use O23.13 When
  • Coders should adhere to the official ICD
  • CM guidelines for obstetric coding, ensuring that the trimester is accurately documented and that any complications are noted
  • Specific criteria for coding infections in pregnancy must be followed

Exclusion Criteria

Do NOT use O23.13 When
No specific exclusions found.
