Diagnostic Criteria for E13.40

1. Diabetes Mellitus Diagnosis

• Type of Diabetes: The patient must have a confirmed diagnosis of diabetes mellitus, which can include Type 1, Type 2, or other specified types of diabetes. The specific type must be documented in the medical record.
• Blood Glucose Levels: Diagnosis typically involves elevated blood glucose levels, which can be determined through various tests:
  • Fasting plasma glucose (FPG) ≥ 126 mg/dL (7.0 mmol/L)
  • Random plasma glucose ≥ 200 mg/dL (11.1 mmol/L) in a patient with classic symptoms of hyperglycemia
  • Hemoglobin A1c (HbA1c) ≥ 6.5% (48 mmol/mol)

2. Presence of Diabetic Neuropathy

• Symptoms: The patient must exhibit symptoms consistent with diabetic neuropathy, which may include:
  • Numbness or tingling in the extremities
  • Pain or burning sensations
  • Weakness in the limbs
• Clinical Evaluation: A thorough neurological examination is necessary to assess sensory and motor function. This may include:
  • Monofilament testing to evaluate sensation
