Code Description

ICD-10 Q11.2 is a billable code used to indicate a diagnosis of microphthalmos.

Key Diagnostic Point:

Microphthalmos is a congenital condition characterized by abnormally small eyes, which can occur in one or both eyes. This condition can be isolated or associated with other congenital anomalies, including systemic syndromes. The severity of microphthalmos can vary significantly, with some individuals experiencing minimal visual impairment while others may have severe vision loss or blindness. The condition can arise from genetic factors, environmental influences during pregnancy, or a combination of both. Microphthalmos is often diagnosed through clinical examination and imaging studies, such as ultrasound or MRI, which can help assess the size and structure of the eyes. Associated conditions may include anophthalmia (absence of one or both eyes), coloboma (defect in the eye structure), and other ocular malformations. Early diagnosis and intervention are crucial for managing visual impairment and associated developmental challenges. Treatment may involve corrective lenses, surgical interventions, and supportive therapies to enhance visual function and quality of life.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and severity of microphthalmos
  • Potential for associated congenital anomalies requiring additional coding
  • Need for precise documentation of ocular measurements and associated conditions
  • Differentiation from similar conditions like anophthalmia and coloboma

Audit Risk Factors

  • Inadequate documentation of ocular measurements
  • Failure to document associated congenital anomalies
  • Misclassification of microphthalmos severity
  • Lack of genetic evaluation documentation

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Pediatric documentation should include detailed ocular examinations, family history of congenital conditions, and developmental assessments.

Common Clinical Scenarios

Common scenarios include newborns presenting with small eyes, referrals for genetic counseling, and assessments for visual impairment.

Billing Considerations

Considerations include the need for multidisciplinary care involving ophthalmology, genetics, and developmental pediatrics.

Genetics

Documentation Requirements

Genetic documentation should include family history, results of genetic testing, and any syndromic associations.

Common Clinical Scenarios

Scenarios may involve genetic counseling for families with a history of microphthalmos or related syndromes.

Billing Considerations

Considerations include the potential for chromosomal abnormalities and the need for comprehensive genetic evaluation.

Coding Guidelines

Inclusion Criteria

Use Q11.2 When
  • 10 coding guidelines for congenital conditions emphasize the importance of accurate documentation of the condition's severity, associated anomalies, and any relevant genetic factors
  • Coders should ensure that all aspects of the patient's condition are captured to support appropriate reimbursement and care

Exclusion Criteria

Do NOT use Q11.2 When
No specific exclusions found.

Frequently Asked Questions

What is the difference between microphthalmos and anophthalmia?

Microphthalmos refers to abnormally small eyes, while anophthalmia is the complete absence of one or both eyes. Accurate coding requires documentation of the presence of ocular tissue.
