Impaired glucose tolerance (oral)
ICD-10 R73.02 is a billable code used to indicate a diagnosis of impaired glucose tolerance (oral).
Impaired glucose tolerance (IGT) is a metabolic condition characterized by elevated blood glucose levels that are not high enough to be classified as diabetes mellitus. It is typically diagnosed through an oral glucose tolerance test (OGTT), where blood glucose levels are measured at intervals after the ingestion of a glucose-rich beverage. Symptoms may be subtle or absent, but individuals may experience fatigue, increased thirst, and frequent urination. Laboratory findings often reveal a 2-hour plasma glucose level between 140 mg/dL and 199 mg/dL during the OGTT. IGT is a significant risk factor for developing type 2 diabetes and cardiovascular diseases. It is often associated with obesity, sedentary lifestyle, and genetic predisposition. Early identification and management of IGT are crucial to prevent progression to diabetes and associated complications.
Clear documentation of OGTT results, patient history, and risk factors for diabetes.
Routine screening in overweight patients or those with a family history of diabetes.
Consideration of comorbid conditions such as hypertension and dyslipidemia.
Documentation of acute symptoms and any relevant lab findings.
Patients presenting with symptoms of hyperglycemia or metabolic syndrome.
Rapid assessment of glucose levels and potential need for immediate intervention.
Used when performing an OGTT to diagnose IGT.
Document the test performed, results, and clinical rationale.
Ensure that the test is ordered based on clinical guidelines.
Diagnosing IGT is crucial as it indicates an increased risk for developing type 2 diabetes and cardiovascular diseases. Early intervention can help prevent progression.
