Other disorders of glucose transport

This code identifies rare, inherited metabolic disorders affecting the cellular uptake or efflux of glucose, distinct from diabetes mellitus or other specified glucose metabolism disorders. These conditions typically involve defects in specific glucose transporter proteins, leading to impaired glucose utilization in various tissues.

Apply this code for documented diagnoses such as Glucose Transporter Type 1 Deficiency Syndrome (GLUT1-DS) or other specified genetic defects in glucose transport mechanisms. Documentation should clearly state the specific transporter affected or the clinical syndrome linked to a glucose transport anomaly, excluding general hyperglycemia or hypoglycemia.

• Do not use for general hyperglycemia, hypoglycemia, or diabetes mellitus; these have more specific codes.
• Requires physician documentation of a specific glucose transport disorder, often confirmed by genetic testing.
• Consider sequencing with codes for associated neurological or systemic manifestations, if present.
