Code Description

ICD-10 D81.810 is a billable code used to indicate a diagnosis of biotinidase deficiency.

Key Diagnostic Point:

Biotinidase deficiency is a rare autosomal recessive disorder characterized by a deficiency of the enzyme biotinidase, which is essential for the recycling of biotin, a B-vitamin crucial for various metabolic processes. This deficiency leads to impaired utilization of biotin, resulting in a range of clinical manifestations. Patients may present with neurological symptoms such as seizures, developmental delay, and hypotonia, as well as skin rashes, alopecia, and conjunctivitis. The hematologic implications include potential anemia and immune dysfunction due to the role of biotin in cellular metabolism and immune response. Early diagnosis through newborn screening and prompt treatment with biotin supplementation can significantly improve outcomes and prevent severe complications. The condition is often diagnosed in infancy, and lifelong management is typically required to maintain normal biotin levels and prevent the recurrence of symptoms. Biotinidase deficiency is part of a broader category of organic acidemias and metabolic disorders, necessitating a multidisciplinary approach for optimal patient care.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of metabolic pathways and enzyme deficiencies.
  • Differentiation from other metabolic disorders with similar presentations.
  • Need for precise documentation of symptoms and laboratory findings.
  • Potential for co-occurring conditions that may complicate coding.

Audit Risk Factors

  • Inadequate documentation of clinical symptoms.
  • Failure to document laboratory results confirming biotinidase deficiency.
  • Misclassification of the condition as a more common metabolic disorder.
  • Lack of follow-up documentation on treatment response.
