Type 1 diabetes mellitus with ketoacidosis without coma

This code signifies a patient diagnosed with Type 1 diabetes who is experiencing diabetic ketoacidosis (DKA) but remains conscious and responsive. DKA is a serious complication characterized by hyperglycemia, metabolic acidosis, and ketonemia, resulting from severe insulin deficiency.

Apply this code when documentation explicitly states Type 1 diabetes and ketoacidosis without any indication of a comatose state. This is typically supported by laboratory findings (e.g., elevated blood glucose, ketones in urine/blood, low pH) and clinical assessment confirming consciousness.

• Always verify the type of diabetes (Type 1 vs. Type 2) and the presence or absence of coma.
• Do not use this code if the patient is in a comatose state; a different subcategory would apply.
• Ensure documentation clearly distinguishes ketoacidosis from other diabetic complications like hyperosmolar hyperglycemic state (HHS).
