Type 1 diabetes with abnormally high blood sugar levels.
Coding Tips
- •Hyperglycemia is often a chronic finding in diabetes; document whether this is acute or chronic elevation
- •Differentiate from diabetic ketoacidosis (E10.10) which is a more severe complication
Clinical Significance
Type 1 diabetes mellitus with hyperglycemia indicates persistently elevated blood glucose levels that are not adequately controlled by current insulin therapy. Chronic hyperglycemia is the primary driver of all diabetic complications including retinopathy, nephropathy, neuropathy, and cardiovascular disease. Documentation of hyperglycemia signals the need for treatment intensification and closer monitoring to prevent end-organ damage.
Documentation Requirements
- ✓The provider must document hyperglycemia in the context of Type 1 diabetes, including specific blood glucose readings or hemoglobin A1c values that demonstrate poor control.
- ✓Current insulin regimen details and any planned modifications should be recorded.
- ✓The documentation should distinguish hyperglycemia from diabetic ketoacidosis, which is a more severe acute complication.
Commonly Confused Codes
E10.10/E10.11 (ketoacidosis) represent more severe metabolic decompensation with acidosis and should be used when DKA criteria are met.E10.9 (without complications) is used when no complications including hyperglycemia are documented.E10.649 (hypoglycemia without coma) represents the opposite metabolic derangement.
