HCC Category Mapping

What This Code Means

Type 1 diabetes with a serious condition where the body produces too much acid in the blood, but the patient remains conscious.

Coding Tips

• •Ketoacidosis is a medical emergency; document arterial blood gas results and pH levels
• •Distinguish from E10.11 by confirming the patient did not lose consciousness

Clinical Significance

Type 1 diabetes mellitus with ketoacidosis without coma is a serious acute metabolic emergency common in patients with insulin-dependent diabetes. Diabetic ketoacidosis occurs when absolute insulin deficiency leads to uncontrolled lipolysis, generating ketone bodies that acidify the blood. This condition is the leading cause of death in children with Type 1 diabetes and requires aggressive management with insulin infusion, fluid resuscitation, and electrolyte correction. The patient remains conscious, distinguishing this from the more severe E10.11.

Documentation Requirements

• ✓Documentation must confirm the Type 1 diabetes diagnosis and the presence of ketoacidosis with supporting laboratory values including arterial blood gas, serum ketones, glucose, electrolyte panel, and anion gap.
• ✓Precipitating factors (infection, insulin omission, pump failure, new diagnosis) should be identified.
• ✓The patient's mental status must confirm the absence of coma.
