Code Description

ICD-10 Q86.1 is a billable code used to indicate a diagnosis of fetal hydantoin syndrome.

Key Diagnostic Point:

Fetal hydantoin syndrome (FHS) is a congenital condition resulting from maternal exposure to the anticonvulsant medication phenytoin during pregnancy. This syndrome is characterized by a range of physical and developmental anomalies, including distinctive facial features such as a broad nasal bridge, a thin upper lip, and a smooth philtrum. Other common manifestations include growth deficiencies, microcephaly, and various congenital malformations affecting the heart, kidneys, and skeletal system. Children with FHS may also exhibit developmental delays and cognitive impairments. The severity of symptoms can vary widely among affected individuals, and early diagnosis and intervention are crucial for optimizing developmental outcomes. Management typically involves a multidisciplinary approach, including pediatricians, geneticists, and developmental specialists, to address the diverse needs of the child.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and severity of symptoms
  • Need for comprehensive documentation of maternal medication history
  • Potential overlap with other congenital syndromes
  • Requirement for detailed clinical descriptions in coding

Audit Risk Factors

  • Inadequate documentation of maternal medication history
  • Failure to capture all associated congenital anomalies
  • Misclassification of the syndrome with other congenital conditions
  • Lack of clarity in clinical notes regarding the severity of symptoms

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Pediatric documentation should include detailed growth and developmental assessments, family history, and any associated congenital anomalies.

Common Clinical Scenarios

Common scenarios include routine pediatric evaluations, referrals for developmental delays, and assessments for congenital anomalies.

Billing Considerations

Pediatric coders must ensure that all congenital anomalies are documented and coded accurately to reflect the child's condition.

Genetics

Documentation Requirements

Genetic documentation should include family history, genetic testing results, and any relevant chromosomal analysis.

Common Clinical Scenarios

Genetic counseling sessions for families with a history of anticonvulsant use during pregnancy and evaluations for genetic syndromes.

Billing Considerations

Genetic coders need to be aware of the implications of maternal medication exposure and its potential impact on genetic counseling.

Coding Guidelines

Inclusion Criteria

Use Q86.1 When
  • According to ICD
  • 10 coding guidelines, congenital conditions should be coded based on the specific anomalies present, and additional codes may be required to capture associated conditions

Exclusion Criteria

Do NOT use Q86.1 When
No specific exclusions found.
