Code Description

ICD-10 Q25.3 is a billable code used to indicate a diagnosis of supravalvular aortic stenosis.

Key Diagnostic Point:

Supravalvular aortic stenosis (SVAS) is a congenital heart defect characterized by a narrowing of the aorta just above the aortic valve. This condition can lead to increased pressure in the left ventricle, resulting in hypertrophy and potential heart failure if left untreated. SVAS is often associated with Williams syndrome, a genetic disorder caused by a deletion of genetic material on chromosome 7. Clinically, patients may present with symptoms such as exercise intolerance, chest pain, or heart murmurs. Diagnosis typically involves echocardiography, which can visualize the narrowing and assess the severity of the stenosis. Treatment options may include surgical intervention to relieve the obstruction and improve blood flow. Long-term follow-up is essential to monitor for potential complications, including re-stenosis or other associated cardiovascular anomalies.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and severity of the condition
  • Association with genetic syndromes like Williams syndrome
  • Need for detailed echocardiographic findings for accurate coding
  • Potential for co-occurring congenital heart defects

Audit Risk Factors

  • Inadequate documentation of associated conditions
  • Failure to specify the severity of the stenosis
  • Lack of follow-up documentation post-surgery
  • Misclassification of the condition with other aortic stenoses

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Pediatric documentation should include growth parameters, developmental milestones, and specific symptoms related to cardiac function.

Common Clinical Scenarios

Common scenarios include routine pediatric check-ups where a heart murmur is detected, leading to further evaluation and diagnosis of SVAS.

Billing Considerations

Consideration must be given to the age of the patient and the potential for growth-related changes in cardiac function.

Genetics

Documentation Requirements

Genetic documentation should include family history, genetic testing results, and any associated syndromic features.

Common Clinical Scenarios

Scenarios may involve genetic counseling for families with a history of Williams syndrome or other genetic conditions associated with SVAS.

Billing Considerations

Coders should be aware of the implications of genetic syndromes on the management and prognosis of SVAS.

Coding Guidelines

Inclusion Criteria

Use Q25.3 When
  • According to the ICD
  • CM coding guidelines, congenital conditions should be coded based on the specific anatomical and physiological characteristics
  • Documentation must support the diagnosis, including any associated conditions or syndromes

Exclusion Criteria

Do NOT use Q25.3 When
No specific exclusions found.
