What This Code Means

Type 1 diabetes with low blood sugar levels that did not result in loss of consciousness.

Coding Tips

• •Document whether hypoglycemia was mild, moderate, or severe to support medical necessity
• •Distinguish from E10.641 by confirming the patient remained conscious during the episode

Clinical Significance

Type 1 diabetes mellitus with hypoglycemia without coma captures episodes of dangerously low blood glucose where the patient maintains consciousness. Recurrent hypoglycemia is a common and significant barrier to optimal glycemic control in Type 1 diabetes, leading to hypoglycemia unawareness, impaired counter-regulatory responses, and reduced quality of life. Documentation of these episodes is critical for insulin dose adjustments and technology interventions such as continuous glucose monitoring.

Documentation Requirements

• ✓The record must document a hypoglycemic episode in a Type 1 diabetic patient with confirmation that coma did not occur.
• ✓Blood glucose readings, symptoms experienced (tremor, diaphoresis, confusion), and treatment provided should be recorded.
• ✓Frequency of hypoglycemic episodes and any pattern analysis should be noted for management planning.
