Computed Tomography of the Sinuses
Computed Tomography of the Sinuses Clinical History Sinusitis Technique 70486 Axial spiral imaging was performed through the paranasal sinuses. Coronal reconstruction imaging was performed. Reference is made to an examination from last year. Comment Progressive mucosal thickening is present in the maxillary, sphenoid, and frontal sinuses and most anterior and some posterior ethmoid air cells. A fluid level is now present in the left maxillary sinus. Soft-tissue attenuation material occludes the ostiomeatal units bilaterally. The spheno-ethmoidal recesses are patent. Leftward posterior bony nasal septal deviation is present, with a small leftward spur, unchanged. The soft tissues are within expected...

Article Overview
This premium radiology coding article explains how to interpret and report CT imaging of the paranasal sinuses in common clinical scenarios. It covers the study type, imaging planes and reconstructions, limited versus complete examinations, technical-component reporting, and related CMS and ACR guidance. The article is intended for coders, billing staff, radiology practices, and compliance reviewers who need to understand the scope of sinus CT reporting and associated documentation issues.
Why This Topic Matters
Sinus CT coding can be affected by whether the exam is limited or complete, whether reconstructions are included, and whether only the technical component is reported. Understanding the article helps readers recognize which general coding and documentation topics are relevant for radiology claims and compliance review.
