ICD-10 Code E16.A – Hypoglycemia level (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E16.A – Hypoglycemia level
What it is
This code identifies a documented hypoglycemia level, meaning the patient has low blood glucose noted in the record. Use it only when the documentation supports hypoglycemia as the coded condition.
Clinical signs
Clinical features may include sweating, shakiness, confusion, weakness, or altered mental status. Clinical features vary; refer to documentation.
When to use this code
Use E16.A when the provider documents hypoglycemia level as the diagnosis, assessment, or reason for care. It may apply to encounters for evaluation, monitoring, or follow-up of low glucose. If the record is unclear, check documentation before coding.
Do not use for
Do not use this code for diabetes-related hypoglycemia unless the chart specifically supports this diagnosis. Do not assign it when low glucose is only a lab finding without documented clinical significance.
Coding tip
Verify that the provider links the hypoglycemia finding to the encounter and code any underlying cause separately when documented.
