Official Description

Radiologic examination, sinuses, paranasal, complete, minimum of 3 views

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 70220 refers to a radiologic examination of the paranasal sinuses, which is a complete study involving a minimum of three views. This procedure is essential for assessing the paranasal sinuses, which are paired, hollow, air-filled cavities located within the facial bones surrounding the nasal cavity. The primary sinuses examined include the frontal sinuses situated in the lower forehead, the maxillary sinuses located in the cheekbones, the ethmoid sinuses found beside the upper nose, and the sphenoid sinuses positioned behind the nose. During this examination, X-rays are utilized to capture images of these structures. X-ray imaging operates on the principle of indirect ionizing radiation, which allows for the visualization of internal body structures by exploiting the varying densities and compositions of human tissues. This differential absorption of X-rays results in a two-dimensional image that reveals the anatomical details of the sinuses. It is important to note that if fewer than three views are obtained, the appropriate code to report is 70210. The use of CPT® Code 70220 is warranted when at least three views are captured, providing a comprehensive examination of the sinuses. The physician interprets these images to identify potential issues such as infections, tumor-like lesions, or fibro-osseous lesions. While conventional radiology has been a standard method for such examinations, it is important to recognize that it has largely been supplanted by more advanced imaging techniques such as computed tomography (CT) or magnetic resonance imaging (MRI), which offer enhanced detail and diagnostic capabilities.

1. Indications

The radiologic examination of the paranasal sinuses using CPT® Code 70220 is indicated for various clinical scenarios where detailed imaging of the sinus cavities is necessary. The following conditions may warrant this procedure:

  • Suspected Sinusitis - This includes acute or chronic inflammation of the sinuses, which may present with symptoms such as facial pain, nasal congestion, and purulent nasal discharge.
  • Evaluation of Sinus Tumors - The procedure is indicated for assessing the presence of neoplastic growths within the sinus cavities, which may require further investigation or intervention.
  • Assessment of Fibro-Osseous Lesions - This includes conditions that affect the bone structure of the sinuses, such as fibrous dysplasia or other bone-related abnormalities.
  • Preoperative Planning - Prior to surgical interventions involving the sinuses, this examination can provide critical information regarding the anatomy and any pathological changes.
  • Trauma Evaluation - In cases of facial trauma, this imaging can help identify fractures or other injuries to the sinus areas.

2. Procedure

The procedure for conducting a radiologic examination of the paranasal sinuses as per CPT® Code 70220 involves several key steps to ensure a comprehensive assessment. The following procedural steps are typically followed:

  • Patient Preparation - The patient is positioned appropriately, often in a seated or supine position, to facilitate optimal imaging of the sinuses. It is essential to ensure that the patient is comfortable and understands the procedure.
  • Image Acquisition - A minimum of three X-ray views of the paranasal sinuses are obtained. These views may include the occipitomental view, the lateral view, and the Caldwell view, among others, to provide a complete assessment of the sinus anatomy and any pathological conditions.
  • Image Processing - The captured X-ray images are processed and displayed for review. This step may involve adjusting the contrast and brightness to enhance the visibility of the sinus structures.
  • Image Interpretation - A qualified physician reviews the images to identify any abnormalities, such as signs of infection, tumors, or other lesions. The interpretation is critical for determining the appropriate clinical management.
  • Documentation - The findings from the examination are documented in the patient's medical record, including any notable observations and recommendations for further action if necessary.

3. Post-Procedure

After the radiologic examination of the paranasal sinuses is completed, there are several considerations for post-procedure care. Patients may be advised to resume normal activities unless otherwise directed by their physician. It is important for the physician to communicate the results of the imaging to the patient, discussing any findings that may require further evaluation or treatment. If any abnormalities are detected, the physician may recommend additional diagnostic procedures, such as a CT scan or MRI, for a more detailed assessment. Follow-up appointments may be scheduled to monitor the patient's condition and response to any prescribed treatments.

CCS Clinical Classification 226 - Other diagnostic radiology and related techniques
26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
X5 Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician
TC Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles
FY X-ray taken using computed radiography technology/cassette-based imaging
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
