(Active) Effective Date: N/A Laboratory - Chemistry Procedures Pathology and Laboratory Feed
Quantitative measurement of glucose in blood, excluding reagent strip methods.
Modifiers like 91 (Repeat clinical diagnostic laboratory test) are applicable when the test is repeated on the same day.
Medical necessity for this test is established by the clinical indication for evaluating blood glucose levels, such as symptoms of diabetes, hypoglycemia, or monitoring of a known metabolic disorder.
Laboratory analysts perform this test by analyzing a patient's blood sample. This often involves adding reagents and using specialized instruments to measure glucose levels accurately.
In simple words: This test measures the amount of sugar (glucose) in your blood using a precise lab method, not a simple test strip. It helps doctors check for problems like diabetes or low blood sugar.
This code represents a quantitative measurement of glucose levels in a patient's blood using methods other than reagent strips. It typically involves laboratory procedures like enzyme assays performed with specialized instruments such as chemistry analyzers and spectrophotometers. This test is commonly used to assess fasting blood glucose levels and plays a crucial role in diagnosing carbohydrate metabolism disorders like diabetes mellitus, hypoglycemia, and pancreatic islet cell cancer. While reagent strip methods can also determine blood glucose, they are specifically excluded from this code.
Example 1: A patient with suspected diabetes undergoes a fasting blood glucose test using code 82947 to determine their baseline glucose level., A patient experiencing symptoms of hypoglycemia undergoes this test to confirm low blood sugar and investigate the cause., A patient with a family history of pancreatic islet cell cancer undergoes regular blood glucose monitoring using this code as part of their screening protocol.
Documentation should include the patient's fasting status (if applicable), the reason for the test, the method used for glucose measurement, and the test results.
