Code Description

ICD-10 Q23.82 is a billable code used to indicate a diagnosis of congenital mitral valve cleft leaflet.

Key Diagnostic Point:

Congenital mitral valve cleft leaflet is a specific type of congenital heart defect characterized by a cleft or split in one of the leaflets of the mitral valve. This malformation can lead to significant hemodynamic consequences, including mitral regurgitation, which may result in volume overload of the left atrium and ventricle. The condition is often associated with other congenital heart defects, such as atrial septal defects or ventricular septal defects, and may be part of syndromic presentations. Diagnosis typically involves echocardiography, which can visualize the cleft and assess its impact on cardiac function. Management may require surgical intervention, particularly if the defect leads to symptomatic heart failure or significant regurgitation. Early detection and appropriate management are crucial to improving outcomes in affected pediatric patients.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and severity of the defect
  • Potential for associated congenital heart defects
  • Need for detailed echocardiographic findings
  • Documentation of clinical symptoms and management plans

Audit Risk Factors

  • Inadequate documentation of echocardiographic findings
  • Failure to document associated congenital conditions
  • Misclassification of severity or type of mitral valve defect
  • Lack of clarity in treatment plans or surgical interventions

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

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

Common Clinical Scenarios

Common scenarios include routine pediatric check-ups where a heart murmur is detected, leading to further investigation and diagnosis of the cleft mitral valve.

Billing Considerations

Consideration should be given to the patient's age, growth, and any associated syndromic features that may impact management.

Genetics

Documentation Requirements

Genetic documentation should include family history of congenital heart defects and any syndromic associations.

Common Clinical Scenarios

Genetic counseling may be sought for families with a history of congenital heart disease, particularly if there are multiple affected family members.

Billing Considerations

Genetic testing may be indicated to rule out chromosomal abnormalities associated with congenital heart defects.
