ICD-10 Code E16.1 – Other hypoglycemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E16.1 – Other hypoglycemia
What it is
E16.1 identifies hypoglycemia that does not fit a more specific category. Use it when the record documents low blood glucose, but the cause or type is not further defined.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include sweating, tremor, hunger, confusion, or weakness, but you should code only when hypoglycemia is clearly documented.
When to use this code
Use E16.1 when the provider documents “other hypoglycemia,” unspecified hypoglycemia, or low blood sugar without a more precise diagnosis. It may apply when the chart does not link the episode to diabetes, medications, or another defined cause.
Do not use for
Do not use this code if the record specifies diabetic hypoglycemia, neonatal hypoglycemia, or another named hypoglycemic disorder. Check documentation before assigning a nonspecific code.
Coding tip
Choose the most specific hypoglycemia code supported by the note; if the cause is unclear, query for clarification rather than assuming.
