Code Description

ICD-10 Q87.81 is a billable code used to indicate a diagnosis of alport syndrome.

Key Diagnostic Point:

Alport syndrome is a genetic disorder characterized by progressive kidney disease, hearing loss, and eye abnormalities. It is caused by mutations in genes responsible for the production of type IV collagen, which is essential for the structural integrity of various tissues, including the kidneys, ears, and eyes. Clinically, patients may present with hematuria, proteinuria, and progressive renal impairment, often leading to end-stage renal disease. Hearing loss typically manifests in late childhood or early adolescence, while ocular abnormalities may include lenticonus and retinal flecks. The condition follows an X-linked inheritance pattern in most cases, although autosomal recessive and dominant forms exist. Diagnosis is often confirmed through genetic testing and family history assessment. Management focuses on monitoring renal function, managing complications, and providing supportive care, including hearing aids and potential renal replacement therapy as needed.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Genetic testing requirements for accurate diagnosis
  • Variability in clinical presentation among patients
  • Need for multidisciplinary care involving nephrology, audiology, and ophthalmology
  • Potential for co-existing congenital conditions

Audit Risk Factors

  • Inadequate documentation of genetic testing results
  • Failure to document the multidisciplinary approach to care
  • Misclassification of the syndrome as a non-genetic condition
  • Lack of detailed family history in the medical record

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Pediatric documentation should include growth parameters, developmental milestones, and any associated congenital anomalies.

Common Clinical Scenarios

Common scenarios include routine monitoring of renal function in children diagnosed with Alport syndrome and referrals for hearing assessments.

Billing Considerations

Pediatric coders should be aware of the age-related manifestations of the syndrome and the importance of early intervention.

Genetics

Documentation Requirements

Genetic documentation must include details of genetic testing, inheritance patterns, and family pedigree.

Common Clinical Scenarios

Genetic counseling sessions for families with a history of Alport syndrome and discussions about reproductive options.

Billing Considerations

Genetic coders should ensure accurate coding of the specific genetic mutations identified and their implications for family members.
