The technical definition of code 71020, according to the Current Procedural Terminology (CPT) codes, is "Paranasal sinuses, 2 or more views." This means that the procedure involves taking at least two x-ray images of the paranasal sinuses from different angles or projections. These views are typically taken to provide a comprehensive assessment of the sinuses, which include the frontal sinuses, ethmoid sinuses, maxillary sinuses, and sphenoid sinuses.
The paranasal sinuses are air-filled cavities located in the skull around the nasal passages. They play a role in producing mucus, humidifying inhaled air, and regulating the temperature and pressure within the nasal cavity. When these sinuses become inflamed or infected, they can cause various symptoms such as facial pain or pressure, nasal congestion, headache, and reduced sense of smell.
A paranasal sinus x-ray is a non-invasive imaging technique that uses a small amount of ionizing radiation to create detailed images of these structures. The radiographer positions the patient and adjusts the x-ray machine to capture the necessary views of the sinuses. Multiple images may be taken from different angles to obtain a thorough evaluation.
Medical code 71020 is used by healthcare professionals, insurance companies, and other entities involved in medical billing and coding to represent the specific procedure of obtaining x-ray images of the paranasal sinuses. This code allows for accurate documentation, tracking, and reimbursement of medical services provided to patients.
