Code Description

ICD-10 E10.1 is a billable code used to indicate a diagnosis of type 1 diabetes mellitus with ketoacidosis.

Key Diagnostic Point:

Type 1 diabetes mellitus with ketoacidosis (DKA) is a serious complication that arises when the body cannot produce enough insulin, leading to high blood glucose levels and the production of ketones. DKA is characterized by hyperglycemia, metabolic acidosis, and ketonuria. Patients may present with symptoms such as excessive thirst, frequent urination, nausea, abdominal pain, and altered mental status. The condition often develops rapidly, particularly in children and adolescents, and can be precipitated by infections, missed insulin doses, or other stressors. Management involves the administration of insulin, fluid replacement, and electrolyte monitoring. Regular monitoring of HbA1c levels is crucial for managing diabetes and preventing complications. An HbA1c level above 7% indicates poor glycemic control, which can increase the risk of DKA. Effective insulin management is essential to maintain blood glucose levels within the target range and prevent the onset of ketoacidosis.
