Code Description

ICD-10 Q18.3 is a billable code used to indicate a diagnosis of webbing of neck.

Key Diagnostic Point:

Webbing of the neck, also known as cervical webbing or pterygium colli, is a congenital malformation characterized by the presence of excess skin or tissue that connects the neck to the shoulders. This condition can vary in severity and may be associated with other congenital anomalies, particularly those affecting the musculoskeletal and cardiovascular systems. The webbing can restrict neck movement and may be accompanied by other facial deformities or syndromes, such as Turner syndrome or Noonan syndrome. Clinical evaluation often includes physical examination and imaging studies to assess the extent of the webbing and any associated anomalies. Treatment may involve surgical intervention to improve neck mobility and cosmetic appearance. Accurate coding requires thorough documentation of the condition and any related congenital anomalies, as well as consideration of the patient's overall health status and any syndromic associations.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and severity of webbing
  • Potential association with other congenital anomalies
  • Need for detailed documentation of associated conditions
  • Differentiation from similar conditions (e.g., pterygium)

Audit Risk Factors

  • Inadequate documentation of associated congenital anomalies
  • Failure to specify the severity of the webbing
  • Misclassification of the condition with similar diagnoses
  • Lack of surgical documentation if applicable

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Documentation should include a detailed physical examination, family history, and any associated congenital conditions. Growth and developmental assessments are also crucial.

Common Clinical Scenarios

Common scenarios include newborn assessments revealing neck webbing, referrals for surgical evaluation, and follow-up visits post-surgery.

Billing Considerations

Consideration of syndromic associations is essential, as many children with neck webbing may have other congenital anomalies.

Genetics

Documentation Requirements

Genetic counseling notes should document family history, genetic testing results, and any syndromic associations. Detailed phenotypic descriptions are necessary.

Common Clinical Scenarios

Scenarios include genetic evaluations for syndromes associated with neck webbing, such as Turner syndrome, and discussions regarding recurrence risks.

Billing Considerations

Genetic implications and the need for multidisciplinary care should be emphasized, particularly in cases with syndromic features.
