Code Description

ICD-10 Q87.43 is a billable code used to indicate a diagnosis of marfan syndrome with skeletal manifestation.

Key Diagnostic Point:

Marfan syndrome is a genetic disorder that affects the connective tissue in the body, leading to a variety of skeletal manifestations. Individuals with Marfan syndrome often exhibit tall stature, long limbs, and arachnodactyly (long, slender fingers). Skeletal abnormalities may include scoliosis, pectus excavatum (sunken chest), and joint hypermobility. The condition is caused by mutations in the FBN1 gene, which encodes the protein fibrillin-1, essential for the structural integrity of connective tissue. Patients may also experience cardiovascular complications, such as aortic dilation or dissection, and ocular issues like lens dislocation. Early diagnosis and management are crucial to prevent serious complications. The skeletal manifestations are particularly significant in pediatric patients, as they can impact growth and development. Comprehensive care often involves a multidisciplinary approach, including genetic counseling, orthopedic evaluation, and regular monitoring of cardiovascular health.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation among patients
  • Need for genetic testing and interpretation of results
  • Potential for associated conditions requiring additional codes
  • Documentation of family history and genetic counseling

Audit Risk Factors

  • Inadequate documentation of genetic testing results
  • Failure to document associated skeletal abnormalities
  • Misclassification of Marfan syndrome with other connective tissue disorders
  • Lack of family history documentation

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Pediatric documentation should include growth measurements, skeletal assessments, and developmental milestones.

Common Clinical Scenarios

Common scenarios include routine check-ups for growth monitoring, referrals for orthopedic evaluation, and assessments for cardiovascular complications.

Billing Considerations

Special considerations include the need for regular monitoring of skeletal development and cardiovascular health, as well as the psychosocial impact of the condition on the child.

Genetics

Documentation Requirements

Genetic documentation should include results of genetic testing, family history, and counseling notes.

Common Clinical Scenarios

Genetic counseling sessions for families, diagnosis confirmation through genetic testing, and discussions about inheritance patterns.

Billing Considerations

Considerations include the interpretation of genetic test results and the implications for family members, as well as the need for ongoing genetic surveillance.
