ICD-10 Code E74.9 – Disorder of carbohydrate metabolism, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E74.9 – Disorder of carbohydrate metabolism, unspecified
What it is
E74.9 is a nonspecific code for a disorder affecting the body’s handling of carbohydrates. Use it when the record confirms a carbohydrate metabolism problem but does not identify a more precise inherited or acquired condition.
Clinical signs
Clinical features vary; refer to documentation. Patients may have signs of abnormal sugar handling, recurrent metabolic symptoms, or findings suggesting a carbohydrate processing disorder, but the exact presentation depends on the underlying cause.
When to use this code
Use E74.9 when the clinician documents a disorder of carbohydrate metabolism without naming a specific diagnosis. It is appropriate when the chart supports the condition, but the type is not further defined. Do not guess a more specific E74 code unless the documentation clearly supports it.
Do not use for
Do not use this code for diabetes mellitus, hypoglycemia alone, or a clearly identified carbohydrate metabolism disorder with its own specific ICD-10 code. If the record is more specific, code that condition instead.
Coding tip
Check the assessment and problem list for a named metabolic disorder before assigning E74.9.
