The CPT® Code 83785 refers to the laboratory test for measuring manganese levels in blood or urine. Manganese is an essential trace mineral that plays a critical role in various physiological functions within the body. It is predominantly found in tissues such as bone, liver, pancreas, and kidneys. This mineral acts as a cofactor for several enzymes, which are vital for detoxifying free radicals, thereby protecting cells from oxidative stress. Additionally, manganese is necessary for the formation of bone and connective tissue, as well as for the synthesis of blood clotting factors and sex hormones. Beyond structural roles, manganese is involved in metabolic processes, including the metabolism of fats and carbohydrates, and it helps regulate blood glucose levels. Furthermore, it contributes to the proper functioning of brain and nerve cells, highlighting its importance in neurological health. The test for manganese levels can be performed using a blood sample obtained through venipuncture, which is a separately reportable procedure. Alternatively, urine specimens can be collected either as a random void or as a 24-hour specimen. The analysis of serum, whole blood, and urine samples is conducted using quantitative inductively coupled plasma-mass spectrometry, a highly sensitive and accurate method for measuring trace elements in biological samples.

The manganese test (CPT® Code 83785) is indicated for the assessment of manganese levels in the body, which may be necessary under the following circumstances:
The procedure for obtaining manganese levels involves several key steps, which are outlined below:
After the manganese testing procedure, there are generally no specific post-procedure care requirements for patients. However, it is important for healthcare providers to communicate the results to the patient and discuss any necessary follow-up actions based on the findings. If the test indicates abnormal manganese levels, further evaluation or intervention may be warranted to address potential deficiencies or toxicities. Patients should also be informed about the importance of reporting any symptoms that may arise following the test, especially if they are related to manganese metabolism.
