ICD-10: N99.521

The ICD-10 code N99.521 specifically refers to an infection of an incontinent external stoma of the urinary tract. This code is part of the broader category of codes that address complications related to urinary stomas, which are surgically created openings that allow urine to exit the body when normal urinary function is impaired.

Clinical Description

Definition

An incontinent external stoma is an artificial opening created in the abdominal wall to divert urine from the bladder, typically due to conditions such as bladder cancer, severe urinary incontinence, or neurological disorders affecting bladder control. The term "incontinent" indicates that the stoma does not have a mechanism to control the flow of urine, leading to continuous drainage.

Infection Overview

Infections associated with external urinary stomas can arise from various factors, including:
- Bacterial colonization: The stoma site can become colonized by bacteria, leading to infection.
- Poor hygiene: Inadequate care of the stoma can increase the risk of infection.
- Skin irritation: Leakage of urine can irritate the surrounding skin, creating an environment conducive to infection.
- Underlying health conditions: Patients with compromised immune systems or other comorbidities may be at higher risk for infections.

Symptoms

Patients with an infection of an incontinent external stoma may present with:
- Redness and swelling around the stoma site.
- Discharge that may be purulent or foul-smelling.
- Pain or tenderness at the stoma site.
- Fever or systemic signs of infection, indicating a more severe condition.

Diagnosis

Diagnosis typically involves:
- Clinical examination: Assessing the stoma and surrounding skin for signs of infection.
- Cultures: Obtaining samples from the stoma site to identify the causative organism.
- Imaging: In some cases, imaging studies may be warranted to evaluate for complications such as abscess formation.

Treatment

Management of an infection of an incontinent external stoma generally includes:
- Antibiotic therapy: Based on culture results to target the specific bacteria involved.
