Unspecified disorder of carbohydrate transport and metabolism

This code signifies a metabolic disturbance affecting the body's ability to process and utilize carbohydrates, where the specific type of disorder is not identified. It encompasses a broad range of conditions impacting carbohydrate absorption, breakdown, or synthesis, without further diagnostic specificity.

This code is appropriate when documentation indicates a general carbohydrate metabolism issue, but the physician has not specified the exact enzymatic defect, transport protein deficiency, or other precise etiology. It is used when a more specific ICD-9-CM code for a carbohydrate disorder (e.g., specific glycogen storage disease, galactosemia) cannot be assigned due to insufficient clinical detail.

• Avoid using this code if a more specific diagnosis for a carbohydrate metabolism disorder is documented.
• Query the provider for further specificity if possible to assign a more precise code.
• This code should be used as a last resort when no other specific carbohydrate metabolism disorder can be identified from the medical record.
