Code Description

ICD-10 Q87.42 is a billable code used to indicate a diagnosis of marfan syndrome with ocular manifestations.

Key Diagnostic Point:

Marfan syndrome is a genetic disorder that affects the body's connective tissue, leading to a variety of systemic manifestations. In particular, ocular manifestations are common, including lens dislocation (ectopia lentis), myopia, and an increased risk of retinal detachment. Patients with Marfan syndrome may also exhibit other congenital malformations such as skeletal abnormalities, cardiovascular issues, and skin changes. The ocular features can significantly impact the patient's quality of life and require careful monitoring and management. Diagnosis is typically made based on clinical criteria, including family history, physical examination, and genetic testing. The presence of ocular manifestations in Marfan syndrome necessitates a multidisciplinary approach to care, involving pediatricians, ophthalmologists, and geneticists to ensure comprehensive management of the condition and its associated complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and severity of Marfan syndrome.
  • Need for detailed documentation of ocular manifestations.
  • Potential overlap with other connective tissue disorders.
  • Requirement for genetic testing results to confirm diagnosis.

Audit Risk Factors

  • Inadequate documentation of ocular findings.
  • Failure to include family history of Marfan syndrome.
  • Misclassification of Marfan syndrome with other connective tissue disorders.
  • Lack of genetic testing documentation.

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Detailed growth and development assessments, family history, and physical examination findings.

Common Clinical Scenarios

Routine check-ups for children diagnosed with Marfan syndrome, monitoring for ocular complications.

Billing Considerations

Pediatric coders should ensure that all manifestations are documented and coded accurately to reflect the complexity of the condition.

Genetics

Documentation Requirements

Genetic testing results, family pedigree, and detailed clinical evaluations.

Common Clinical Scenarios

Genetic counseling sessions for families with a history of Marfan syndrome, discussing risks and management options.

Billing Considerations

Genetic coders must ensure that the genetic basis of Marfan syndrome is clearly documented to support the diagnosis.
