Code Description

ICD-10 E74 is a billable code used to indicate a diagnosis of other disorders of carbohydrate metabolism.

Key Diagnostic Point:

E74 encompasses a variety of metabolic disorders that affect carbohydrate metabolism, including conditions resulting from enzyme deficiencies, genetic metabolic disorders, and other related issues. These disorders can lead to abnormal glucose levels, impaired insulin function, and various systemic effects. Common examples include galactosemia, glycogen storage diseases, and disorders of fructose metabolism. Patients may present with symptoms such as hypoglycemia, failure to thrive, or metabolic acidosis. Diagnosis often involves biochemical tests to assess enzyme activity and genetic testing to identify specific mutations. Management typically includes dietary modifications, enzyme replacement therapy, and monitoring of metabolic parameters to prevent complications. The complexity of these disorders can vary significantly based on the specific enzyme deficiency or metabolic pathway involved, necessitating a thorough understanding of the underlying pathophysiology for accurate coding and treatment.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying conditions leading to carbohydrate metabolism disorders
  • Need for precise biochemical and genetic testing results for accurate coding
  • Potential for overlapping symptoms with other metabolic disorders
  • Variability in clinical presentation and management strategies

Audit Risk Factors

  • Inadequate documentation of specific enzyme deficiencies
  • Failure to include genetic testing results
  • Misclassification of the disorder due to overlapping symptoms
  • Lack of clarity in treatment plans and dietary modifications
