It is important for medical coding and billing specialists to know about the nervous system for accurate coding and billing. The nervous system is a complex roadmap that stretches from the top of the head to the bottom of the toes and knowing the intricacies not only helps to assign the correct code, but it also helps to rule out the wrong ones. If a physician states a patient has a central nervous system disorder, a medical coder/biller would know that involves the brain and spinal cord. If the physician mentioned nerves, the medical biller/coder would know that the peripheral nervous system is affected. Ganglia are also a part of the peripheral nervous system. "Ganglia are clusters of nerve cell bodies found throughout the body. They are part of the peripheral nervous system and carry nerve signals to and from the central nervous system." (Coelho, 2021) What if a person has a headache? This is one of the most common functional disorders of the nervous system. It could also be tricky to code properly since there are many types and a headache can be a central and peripheral nervous system disorder. In a situation like this, asking for clarification and getting questions answered can help to make sure the proper billing codes are being used.
