Code Description

ICD-10 E10.40 is a billable code used to indicate a diagnosis of type 1 diabetes mellitus with diabetic neuropathy, unspecified.

Key Diagnostic Point:

Type 1 diabetes mellitus is a chronic condition characterized by the body's inability to produce insulin due to autoimmune destruction of pancreatic beta cells. Diabetic neuropathy is a common complication of diabetes, resulting from prolonged hyperglycemia that damages peripheral nerves. Patients with E10.40 may experience symptoms such as numbness, tingling, pain, or weakness in the extremities. The unspecified nature of the neuropathy indicates that the specific type (e.g., peripheral, autonomic) has not been documented. Management of type 1 diabetes involves regular monitoring of blood glucose levels, maintaining HbA1c levels below 7% to minimize complications, and insulin therapy. Insulin management is crucial, as patients may require multiple daily injections or continuous subcutaneous insulin infusion. Regular foot examinations and patient education on glycemic control are essential to prevent further complications.

Complexity Factors

  • Need for precise documentation of neuropathy type
  • Differentiation from other types of diabetes-related neuropathy
  • Management of insulin therapy and monitoring of HbA1c levels
  • Potential for multiple co-morbid conditions

Audit Risk Factors

  • Inadequate documentation of neuropathy symptoms
  • Failure to document HbA1c levels
  • Lack of clear insulin management records
  • Inconsistent coding of diabetes-related complications
