E11 refers to Type 2 diabetes mellitus, a category of diabetes mellitus diagnoses distinguished by cause—whether due to an underlying disease, medication, autoimmune destruction, insulin resistance, or other specified factors. These conditions require distinct treatment approaches but share complications like hyperglycemia, neuropathy, nephropathy, and retinopathy.

Symptoms

Increased thirst and urination – Classic signs of uncontrolled blood sugar
Fatigue – Due to poor cellular glucose uptake
Blurred vision – Caused by fluid shifts in the eye
Slow-healing wounds – Common in chronic diabetes
Unexplained weight loss – Especially in Type 1 diabetes
Numbness or tingling – Indicating diabetic neuropathy
Recurring infections – Skin, urinary tract, or gums

Diagnosis

Diagnosis of Type 2 diabetes mellitus includes fasting plasma glucose, HbA1c, oral glucose tolerance test, and C-peptide levels. Autoantibody screening helps classify Type 1 diabetes, while history of drug exposure or underlying illness may explain E08 or E09 codes. Comprehensive metabolic panel and urine tests assess organ involvement.

ICD10 Code Usage

ICD10 code E11 is used in endocrinology, primary care, and internal medicine to classify diabetes by etiology. These codes support personalized treatment planning, patient education, complication tracking, and billing documentation.

A: This code refers to Type 2 diabetes mellitus, a specific type of diabetes based on cause—ranging from autoimmune to chemical exposure.

Q2: What are the common complications?
A: Diabetic neuropathy, retinopathy, kidney disease, cardiovascular complications, and poor wound healing.

Q3: Is insulin required?
A: Type 1 always requires insulin. Type 2 and secondary diabetes may require oral meds, insulin, or both depending on severity.

Q4: How is it monitored?
A: Through HbA1c every 3 months, daily blood glucose checks, and screening for long-term complications.

Q5: Can it be reversed?
A: Type 2 can sometimes go into remission with lifestyle changes. Type 1 and secondary forms require lifelong management.
