How do coders report diabetic ketoacidosis in ICD-10-CM?

For FY2018 there is a new code to report Type 2 diabetic ketoacidosis (DKA). This was previously reported with code E13.1-, other specified diabetes mellitus with ketoacidosis with or without coma. Now, there is a code specifically for reporting this diagnosis. E11.1- is used to report Type 2 diabetes with DKA with or without coma.

What is diabetic ketoacidosis (DKA)?

DKA is life threatening complication in patients with diabetes. This typically occurs in patients with type 1 diabetes but can also be found in patients with type 2. When a patient has DKA it is implied that they also have hyperglycemia so no additional code is needed to report that the diabetes is with hyperglycemia. A separate standalone code for hyperglycemia is also not reported and there is an excludes1 note in the tabular.

DKA occurs when the body produces high levels of blood acids known as ketones. This develops when the body isn’t producing enough insulin. When the body does not produce or have enough insulin, the body begins to break down fat as fuel. When the body switches to burning fat this produces a buildup of acids that are called ketones. Excess ketones build up and are spilled over into the urine.

Symptoms of DKA:

  • Nausea & Vomiting
  • Abdominal pain
  • Breathing difficulties/shortness of breath
  • Increased urination
  • Weakness
  • Confusion
  • Loss of consciousness
  • Breath that smells of fruit
  • Excessive thirst
  • High blood sugar level and ketone levels in your urine

Causes of DKA:

  • UTI
  • Pneumonia
  • Other infection
  • Gastroenteritis
  • Noncompliance with insulin or inadequate insulin administration
  • Pregnancy
  • MI
  • Stroke
  • Drug and alcohol use
  • Eating disorders
  • Physical trauma
  • Emotional trauma
  • Certain medication uses especially steroids and diuretics

Treatment for DKA:

Insulin is given to reverse the process that caused the patient to go into DKA. In severe cases, this will be given intravenously. Once the blood sugar levels fall to be below 240 mg/dL and the blood is no longer acidic, regular insulin therapy can be resumed. Fluid and electrolytes will also be replaced. The fluids are given either via mouth or IV and are given to replace the fluid lost through excessive urination. The fluid replacement will also help to dilute the excess sugar in the blood. The electrolytes will be given intravenously and are sodium, potassium and chloride. This replacement will help keep the heart, muscles and nerve cells functioning properly.

Prevention of DKA:

  • Strict adherence to insulin or oral medication regimen
  • Monitor blood sugars and when uncontrolled treat with insulin as instructed
  • Healthy eating and physical activity
  • When ill or under stress, test your urine for excess ketones (test can be purchased over the counter)
  • Seek emergency medical care if DKA is suspected before it gets out of control
