Elevated blood glucose level (R73)

ICD-10 codes in the R73 section are used to identify various conditions related to elevated blood glucose levels, ranging from abnormal glucose findings to specific diagnoses like impaired fasting glucose or prediabetes. These codes help categorize glucose abnormalities when diabetes is not formally diagnosed.

This section includes R73 for general elevated blood glucose and extends to more detailed codes such as R73.01 for impaired fasting glucose, also known as impaired fasting glycemia. The code R73.02 covers impaired glucose tolerance detected by oral tests, linked with terms like impaired glucose tolerance test and related metabolic conditions. R73.03 specifies prediabetes, including prediabetes during pregnancy. R73.09 captures other abnormal glucose findings, such as glucose levels outside normal ranges or unstable blood glucose, often noted during glucose tolerance tests. Lastly, R73.9 represents unspecified hyperglycemia, covering various scenarios like drug-induced or steroid-induced hyperglycemia, poor glycemic control, and metabolic stress-related high glucose levels. Medical coders use these codes to report abnormal glucose metabolism findings clearly and accurately in medical records and billing when diabetes is not definitively diagnosed.
