Code Description

ICD-10 Q71.42 is a billable code used to indicate a diagnosis of longitudinal reduction defect of left radius.

Key Diagnostic Point:

The longitudinal reduction defect of the left radius is a congenital malformation characterized by the underdevelopment or absence of the radius bone in the forearm. This condition can lead to significant functional impairment, affecting the range of motion and strength of the affected limb. Patients may present with a shortened forearm, altered wrist mechanics, and potential associated deformities in the hand. The defect can occur in isolation or as part of a syndrome involving other congenital anomalies. Diagnosis is typically made through physical examination and imaging studies, such as X-rays, which reveal the extent of the reduction defect. Management may involve orthopedic interventions, including corrective surgery, to improve function and appearance. Early intervention is crucial for optimizing outcomes and facilitating normal development in affected children.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and severity of the defect
  • Potential for associated syndromic conditions
  • Need for detailed documentation of functional impairment
  • Variations in treatment approaches and outcomes

Audit Risk Factors

  • Inadequate documentation of the defect's severity
  • Failure to note associated conditions or syndromes
  • Misclassification of the defect as an acquired condition
  • Lack of clarity in treatment plans and outcomes

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Pediatric documentation should include detailed physical examination findings, imaging results, and treatment plans. Growth and developmental assessments are also critical.

Common Clinical Scenarios

Common scenarios include initial diagnosis during routine pediatric examinations, referrals for orthopedic evaluation, and follow-up visits post-surgery.

Billing Considerations

Coders should ensure that all relevant congenital conditions are documented, especially if they impact treatment decisions.

Genetics

Documentation Requirements

Genetic documentation should include family history, genetic testing results, and any syndromic associations that may be present.

Common Clinical Scenarios

Scenarios may involve genetic counseling for families, discussions of recurrence risks, and management of associated syndromes.

Billing Considerations

Coders should be aware of the implications of genetic findings on the overall management of the patient and ensure accurate coding of any syndromic conditions.

Coding Guidelines

Inclusion Criteria

Use Q71.42 When
  • According to ICD
  • 10 coding guidelines, congenital conditions should be coded based on the specific defect and any associated conditions
  • Documentation must support the diagnosis and reflect the clinical picture accurately

Exclusion Criteria

Do NOT use Q71.42 When
No specific exclusions found.
