E11.9 Diagnosis Code: Type 2 diabetes mellitus without complications
The E11.9 is an ICD code that’s included in the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM), and it is used to designate “Type 2 diabetes mellitus without complications.”
Type 2 Diabetes Mellitus is a type of diabetes that normally occurs in middle-aged people or those in their late adulthood. The difference between Type 1 and Type 2 diabetes lies in the pancreas. For Type 1, the pancreas don’t make insulin. For Type 2, the pancreas still makes insulin, but nowhere near as much as it normally does. Moreverover, people with Type 2 diabetes become resistant to the effects of insulin.
This ICD-10 code is used to diagnose people with Type 2 Diabetes Mellitus, but the patient is not dealing with any complications that normally arise from this type of condition, such as heart diseases, blood vessel diseases, nerve damage, eye damage, and skin conditions.
Is the E11.9 billable?
Yes, the E11.9 ICD-10 code is billable and can be used to designate a patient for reimbursement purposes.
E11.9 clinical information:
Type 2 Diabetes Mellitus is a type of diabetes that is commonly found in adult patients who are middle-aged or are in their late adulthood. A patient’s pancreas produces less insulin for the body, and the body builds up a resistance to the effects of insulin.
Patients who have Type 2 Diabetes Mellitus have the following symptoms:
- They are unusually hungry or thirsty
- The excessively urinate
- They lose significant weight in a short span of time
- They become more prone to infections
- They have high blood glucose levels
- They have hyperosmolar syndrome (which is caused by high blood glucose levels)
Patients suspected of having Type 2 Diabetes Mellitus will undergo certain tests to confirm that they have it, like Fasting Plasma Glucose (FPG) and OGTT Oral Glucose Tolerance (OGTT) tests.
In cases where the patient has been diagnosed with Type 2 Diabetes Mellitus but is not currently experiencing any associated complications, the E11.9 ICD-10 code will be used.. Do note that this diagnosis code is classified as a Questionable Admission Code. It is normally not a justifiable code to have a patient admitted into a hospital for acute care if it is used as a principal diagnosis. They aren’t dealing with complications, after all.
Treatments for this will include a change in diet. The patient’s meals should have no trans fats, they should be low in saturated fats and cholesterol, and low in total calories. Medicine like Metformin is also commonly prescribed for patients with Type 2 Diabetes.
Insulin is prescribed as the body's pancreas is unable to produce an adequate amount of insulin to counter the insulin resistance that has developed. This prescription helps combat the accumulation of glucose in the bloodstream.
