    ICD-10-CM Code For Elevated Blood Glucose Level: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group R73 includes nonspecific abnormal findings of elevated blood glucose such as elevated fasting glucose and abnormal glucose tolerance tests, representing disturbances in glucose homeostasis that do not yet meet criteria for a diabetes mellitus diagnosis. These ICD-10-CM diagnosis codes are used to document clinical scenarios where laboratory testing reveals hyperglycemia or impaired glucose regulation, capturing disease severity and the need for further evaluation. Accurate coding within the ICD-10-CM R73 group supports complete clinical documentation and appropriate reimbursement.

    ICD-10-CM R73: Elevated Blood Glucose Level Overview

    The ICD-10-CM R73 group captures abnormal elevations of blood glucose identified on laboratory testing without a definitive diagnosis of diabetes mellitus. These codes target metabolic and endocrine screening findings related to glucose regulation. Accurate coding ensures clinical records reflect abnormal test results and supports appropriate reimbursement tied to diagnostic evaluation.

    When to Use

    Use a code from this group when laboratory results document elevated glucose levels or abnormal glucose tolerance and no established diagnosis of diabetes mellitus is recorded. These codes are appropriate for reporting isolated abnormal test findings to reflect the need for further evaluation or monitoring.
