Code Description

ICD-10 E10.649 is a billable code used to indicate a diagnosis of type 1 diabetes mellitus with hypoglycemia without coma.

Key Diagnostic Point:

E10.649 refers to Type 1 diabetes mellitus characterized by episodes of hypoglycemia that do not result in a coma. This condition arises when the body's insulin production is insufficient, leading to elevated blood glucose levels. Patients with Type 1 diabetes often require exogenous insulin to manage their blood sugar levels. Hypoglycemia can occur due to various factors, including excessive insulin administration, missed meals, or increased physical activity. Symptoms of hypoglycemia may include sweating, trembling, confusion, and irritability. It is crucial for patients to monitor their blood glucose levels regularly and manage their insulin dosages carefully to prevent hypoglycemic episodes. The management of Type 1 diabetes involves a comprehensive approach, including dietary modifications, regular exercise, and continuous glucose monitoring. The goal is to maintain HbA1c levels below 7% to minimize the risk of long-term complications such as neuropathy, retinopathy, and cardiovascular diseases.
