About the B90 Code Range
The ICD-10-PCS root operation Plain Radiography (Code B90) refers to imaging procedures that use standard X-rays to capture images of specific anatomical areas. It is part of the Imaging section and focuses on non-invasive visualization of structures within the ear, nose, mouth, and throat region.
This operation includes detailed imaging of various body parts such as the Paranasal Sinuses (B902ZZ), the Right and Left Parotid Glands with different contrast types like high osmolar (B9040ZZ) or low osmolar (B9041ZZ), and the Submandibular Glands. It also covers imaging of Bilateral Salivary Glands using various contrast media (B90D0ZZ, B90D1ZZ), and adjacent structures such as the Nasopharynx/Oropharynx (B90FZZZ) and Mastoids (B90HZZZ). These codes exemplify the application of plain radiography for diagnostic assessment within the head and neck area, aiding clinical evaluation without surgical intervention.
