Endoscopic Sinus Surgery (Winter 1993)
Winter 1993 pages 22-25 Coding Clarification Endoscopic Sinus Surgery Introduction The paranasal sinuses are air spaces lined by a mucous secreting membrane that connect to the nasal cavity through small openings. Another word for this opening is an ostium. If the ostium of a sinus becomes blocked, obstruction of mucous flow occurs resulting in stagnation and infection. This is usually associated with marked thickening of the lining mucous membrane. At this point, surgical enlargement of the opening into the nose may be considered sometimes, along with removal of the thickened infected lining mucous membrane. There are four separate sinus...

Article Overview
This CPT Assistant article reviews the winter 1993 update on endoscopic sinus surgery coding. It is aimed at coding professionals, auditors, and clinical staff who need to understand how the revised CPT framework organizes diagnostic and surgical endoscopic procedures for the paranasal sinuses, related transnasal approaches, and select adjacent procedures. The article also discusses the accompanying glossary of sinus and orbital terms and the relationship between the revised code structure and earlier deleted codes.
Why This Topic Matters
The article helps readers recognize that the coding structure for endoscopic sinus surgery changed in a way that affected how procedures are grouped and reported. It is relevant for accurate CPT review, code selection, and understanding the anatomy-driven organization of the revised section.
