CPT Code 83036 | Hemoglobin A1C Test

CPT 83036 describes a laboratory test measuring the blood glucose (sugar) level over the past two to three months. This test is known as the Hemoglobin A1C test, used to monitor and diagnose diabetes.

What Is CPT Code 83036?

CPT code 83036 describes a laboratory test that measures the blood’s average glucose (sugar) level over the past two to three months.

A1C stands for “glycated hemoglobin” and is a test measuring the percentage of hemoglobin in the blood coated in glucose. Hemoglobin is a protein in red blood cells that carries oxygen.

When glucose is in the blood, it can stick to the hemoglobin, forming glycated hemoglobin.

The A1C test is used to monitor diabetes and to help diagnose the condition. It is typically ordered as part of a routine examination for people with diabetes and is a good indicator of how well the disease is managed over time.

An average A1C level is typically less than 6.5%, while levels above 6.5% may indicate poor control of diabetes.

Description

The CPT book describes CPT code 83036 as: “Hemoglobin; glycosylated (A1C).”

Procedure

The A1C test measures a person’s average blood sugar level over the past three months by determining the amount of sugar attached to the hemoglobin in red blood cells.

When sugar enters the bloodstream, it can bind to the hemoglobin and remain there for the red blood cell’s lifespan, typically around 120 days. 

Therefore, the higher the sugar level in the blood, the more sugar will be attached to the red blood cells.

An average, healthy person should have an A1C level below 7%. To perform the test, a blood sample is collected and analyzed using several laboratory methods, such as high-performance liquid chromatography (HPLC), immunoassay, or boronate affinity chromatography.

The result is a percentage, which reflects the amount of sugar attached to the red blood cells.

How To Use CPT 83036

Report CPT 83036 if a provider analyzes glycosylated hemoglobin (A1C) using electrophoresis or chromatography.

When an identified hemoglobin variant is present, you can use CPT 83020 or CPT 83021. If the test is for fecal hemoglobin detection by immunoassay, you may use CPT code 82274 instead of CPT 83036.

CPT code 83036 is a CLIA-Waived test.
