Code Description

ICD-10 Q87.418 is a billable code used to indicate a diagnosis of marfan syndrome with other cardiovascular manifestations.

Key Diagnostic Point:

Marfan syndrome is a genetic disorder that affects connective tissue, leading to a variety of systemic manifestations. Patients with Marfan syndrome often exhibit cardiovascular abnormalities, including aortic dilation, mitral valve prolapse, and other structural heart defects. In addition to cardiovascular issues, individuals may present with other congenital malformations such as scoliosis, pectus excavatum, and arachnodactyly. The condition can also be associated with congenital malformations of the skin, such as striae, and abnormalities of the breast, spleen, and adrenal glands. These additional manifestations complicate the clinical picture and require careful documentation and coding to ensure accurate representation of the patient's condition. The complexity of Marfan syndrome lies in its variable expressivity and the potential for overlapping symptoms with other genetic disorders, necessitating a thorough clinical evaluation and genetic testing to confirm the diagnosis and assess the full spectrum of congenital anomalies present.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Variable expressivity of Marfan syndrome leading to diverse clinical presentations.
  • Need for comprehensive documentation of associated congenital malformations.
  • Differentiation from other connective tissue disorders with similar symptoms.
  • Potential for multiple co-existing congenital conditions requiring accurate coding.

Audit Risk Factors

  • Inadequate documentation of associated congenital malformations.
  • Failure to specify the type of cardiovascular manifestations present.
  • Misclassification of Marfan syndrome severity or associated conditions.
  • Lack of genetic testing documentation to support the diagnosis.

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Pediatric documentation should include growth parameters, developmental milestones, and specific congenital anomalies observed during physical examination.

Common Clinical Scenarios

Common scenarios include routine evaluations for growth and development in children with known Marfan syndrome, assessments for scoliosis, and monitoring for cardiovascular complications.

Billing Considerations

Consideration must be given to the age of the patient, as manifestations may evolve over time, requiring ongoing assessment and documentation.

Genetics

Documentation Requirements

Genetic documentation should include family history, results of genetic testing, and any genetic counseling provided to the patient and family.

Common Clinical Scenarios

Scenarios may involve genetic counseling for families with a history of Marfan syndrome, interpretation of genetic test results, and discussions regarding the risk of transmission to offspring.

Billing Considerations

Accurate coding requires understanding the genetic basis of Marfan syndrome and its implications for associated congenital anomalies.

Coding Guidelines

Inclusion Criteria

Use Q87.418 When
  • Follow official coding guidelines for congenital conditions, ensuring that all manifestations are documented and coded accurately
  • Use additional codes to capture specific congenital anomalies associated with Marfan syndrome

Exclusion Criteria

Do NOT use Q87.418 When
No specific exclusions found.

Frequently Asked Questions

What documentation is required to support the diagnosis of Marfan syndrome?

Documentation should include clinical findings consistent with Marfan syndrome, results from genetic testing, and any associated congenital anomalies. It is essential to provide a comprehensive overview of the patient's condition to support accurate coding.
