HCC Category Mapping

What This Code Means

Type 2 diabetes with ketoacidosis, a serious condition where acids build up in the blood due to improper insulin function, but the patient remains conscious.

Coding Tips

• •Verify that ketoacidosis is documented and that the patient is NOT in a coma before assigning this code
• •If coma is present, use E11.11 instead

Clinical Significance

Type 2 diabetes mellitus with ketoacidosis without coma is a serious acute metabolic complication where insulin deficiency leads to excessive fatty acid breakdown and ketone body accumulation, resulting in metabolic acidosis. While more common in Type 1 diabetes, DKA in Type 2 diabetes is increasingly recognized, particularly in patients with ketosis-prone Type 2 diabetes or during severe physiological stress. This condition requires urgent hospital-based management.

Documentation Requirements

• ✓Documentation must confirm both Type 2 diabetes and diabetic ketoacidosis with the patient remaining conscious.
• ✓Laboratory values including blood glucose, arterial blood gas, serum ketones, anion gap, and bicarbonate levels should be recorded.
• ✓The precipitating factor (infection, medication non-compliance, new onset) and treatment protocol must be documented.
