What ICD-10-CM code should be reported for elevated blood sugar?

The correct code for reporting elevated blood sugar is R73.09. This specific code is utilized to identify abnormal glucose levels in the blood that do not meet the criteria for diabetes mellitus or other specific conditions. R73.09 refers to "Other abnormal glucose," indicating that the elevated blood sugar is present but not classified under a definitive diagnosis, allowing for the documentation of an abnormal finding that might need further investigation or monitoring.

The other options represent different conditions or abnormal findings related to glucose and blood sugar levels. For example, R71.1 pertains to abnormal findings in the blood but does not specifically address glucose levels. R73.8 is used for other specified abnormal glucose levels but is broader and less specific than R73.09. R74.8 relates to other specified abnormal tests, which is not directly applicable to elevated blood sugar alone. Thus, R73.09 is the most accurate choice for capturing the specific diagnosis of elevated blood sugar without further categorization.
