Code Description

ICD-10 E74.818 is a billable code used to indicate a diagnosis of other disorders of glucose transport.

Key Diagnostic Point:

E74.818 refers to a group of metabolic disorders characterized by abnormalities in glucose transport mechanisms. These disorders can arise from various causes, including genetic mutations affecting glucose transporter proteins, enzyme deficiencies, or other metabolic dysfunctions. Patients may present with symptoms such as hypoglycemia, hyperglycemia, or metabolic acidosis, depending on the specific transport defect. The glucose transporters, primarily GLUT1, GLUT2, and GLUT4, play crucial roles in cellular glucose uptake and regulation of blood glucose levels. Disorders in glucose transport can lead to significant clinical manifestations, including neurological deficits, growth retardation, and complications related to diabetes. Diagnosis typically involves biochemical tests, genetic testing, and sometimes imaging studies to assess the impact on organ systems. Management strategies may include dietary modifications, enzyme replacement therapies, or pharmacological interventions aimed at improving glucose metabolism.
