0.000What This Code Means
A metabolic condition where the body has difficulty moving glucose into cells properly, but the specific type of transport problem is not identified.
Coding Tips
- •This is a catch-all code; attempt to obtain more specific diagnosis documentation before coding
- •Query the provider if additional testing results are available to specify the glucose transport defect
Clinical Significance
Disorders of glucose transport, unspecified, is used when a glucose transport disorder has been diagnosed but the specific transporter defect is not identified. This may occur during diagnostic workup before genetic testing results are available. Given the clinical importance of identifying the specific transporter involved for treatment planning, this code should prompt further investigation.
Documentation Requirements
- ✓Provider diagnosis of a glucose transport disorder
- ✓Laboratory or clinical evidence suggesting a glucose transport defect
- ✓Documentation of why specific transporter identification is pending or not possible
- ✓Clinical manifestations prompting the diagnosis
- ✓Plan for additional diagnostic workup including genetic testing
