Nosology is not the study of noses. Rather, it is classifying diseases in a systematic manner. Companies like http://regentrcm.com have received receipts for our medical bills. Often, they include a variety of codes that gives the insurance company quite a bit of information. For instance, ICD-9 codes  or ASC revenue cycle (International Statistical Classification of Diseases and Related Health Problems) explain the body part that was examined/treated, including what side of the body the problem occurred on. These codes describe both illnesses and injuries.


They list almost every disease for every body system, from head to toe. Also included are some conditions that can occur during a woman’s pregnancy, various symptoms (separate from illnesses), patient physical complaints and mental disorders. Injuries and poisonings are also included in these listings. This coding system is a U.S. adaptation of the international ICD-9 alphanumeric codes. There’s an additional reason ICD-9 codes are used. These codes help to gather and analyze data. Studies have been done seeking the effectiveness of vaccine safety by their use. Cancer survivorship has been tracked. Mortality data is also gathered. There is another type of coding called Current Procedural Terminology (CPT). CPT is actually a registered trademark of the American Medical Association. There is a CPT Editorial Panel that makes certain these codes reflect the latest in medical care. Meeting three times a year, practicing physicians, diagnostic test developers, manufacturers of medical devices and various advisors from over one hundred societies meet to ensure the these codes reflect the latest in medical care.

Both sets of codes for ASC revenue cycle management: ICD-9 and CPT codes are subject to change. In fact, every year updates are done that include new codes and eliminate others. Why is all of this important? It provides a consistent basis for billing, both for the medical provider as well as for the insurance company throughout the country. Financial reimbursement is based on these codes. Private insurance companies, often called “third party payers”, often take their “cue” from Medicare regarding reimbursement rules. Coding is a complicated and tedious job. It’s vital that it is done correctly, as reimbursement is dependent upon it. Additionally, use of these codes increase accuracy and efficiency for both the medical provider and insurance company. It helps streamline a complicated process to track. The people that code your bills are called medical coders. Very often, they go to school to formally learn how to do this job. Furthermore, continuing education is required to keep up with the yearly changes. Could it be that medical coders can also be called nosologists?
