Code Description

ICD-10 N39.46 is a billable code used to indicate a diagnosis of mixed incontinence.

Key Diagnostic Point:

Mixed incontinence is a condition characterized by the simultaneous presence of both stress incontinence and urge incontinence. Stress incontinence occurs when physical activities such as coughing, sneezing, or exercise put pressure on the bladder, leading to involuntary leakage of urine. Urge incontinence, on the other hand, is the sudden, intense urge to urinate followed by involuntary loss of urine. This dual presentation can complicate diagnosis and treatment, as patients may experience varying symptoms that can overlap. Mixed incontinence is often associated with underlying conditions such as urethritis, urethral strictures, and other urinary system disorders. It can significantly impact a patient's quality of life, leading to social embarrassment, anxiety, and depression. The management of mixed incontinence typically involves a combination of behavioral therapies, pelvic floor exercises, medications, and in some cases, surgical interventions. Accurate coding is essential for proper treatment planning and reimbursement, making it crucial for coders to understand the nuances of this condition and its related disorders.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between stress and urge incontinence symptoms
  • Potential overlap with other urinary disorders
  • Need for comprehensive patient history and documentation
  • Variability in treatment approaches based on underlying causes

Audit Risk Factors

  • Inadequate documentation of symptoms
  • Failure to specify type of incontinence
  • Misclassification of mixed incontinence as solely stress or urge
  • Lack of supporting clinical evidence for diagnosis

Specialty Focus

Medical Specialties

Urology

Documentation Requirements

Detailed patient history, including symptom onset, frequency, and severity; results of urodynamic studies if performed.

Common Clinical Scenarios

Patients presenting with urinary leakage during physical activity or sudden urges; patients with history of urinary tract infections or pelvic surgeries.

Billing Considerations

Consideration of comorbidities such as diabetes or neurological disorders that may affect bladder function.

Gynecology

Documentation Requirements

Documentation of pelvic examinations, assessment of pelvic floor strength, and any relevant obstetric history.

Common Clinical Scenarios

Women experiencing incontinence post-childbirth or with pelvic organ prolapse.

Billing Considerations

Understanding the impact of hormonal changes on urinary function in menopausal patients.

Inclusion Criteria

Use N39.46 When
  • According to ICD
  • 10 guidelines, mixed incontinence should be coded when both stress and urge incontinence are documented
  • Coders should ensure that the diagnosis is supported by clinical findings and that other urinary disorders are ruled out

Exclusion Criteria

Do NOT use N39.46 When
