Balloon Catheter Dilation of the Sinuses: A 2011-2014 MarketScan Analysis.

OBJECTIVE: This study uses a large national claims-based database to analyze recent practice patterns related to balloon catheter dilation (BCD) of the sinuses. STUDY DESIGN: Retrospective study. SETTING: Academic. SUBJECTS AND METHODS: Patients with chronic rhinosinusitis (CRS) undergoing BCD and functional endoscopic sinus surgery (FESS) from 2011 to 2014 were identified in Truven Health MarketScan Databases with codes from the International Classification of Diseases, Ninth Revision, Clinical Modification and Current Procedural Terminology, Fourth Edition. Prevalence of CRS and frequency of sinus procedures were trended over the study period. Information related to site of service, demographics, and comorbidities was analyzed. RESULTS: Although the prevalence of CRS and sinus procedures remained stable over the study period, there was a consistent increase in the annual number of BCD procedures performed in the office. Among BCD procedures, multisinus dilation had the largest increase. A higher proportion of patients undergoing BCD were women, aged ≥65 years, and from the South. There was a higher prevalence of headache disorder and allergic rhinitis in the BCD group, as compared with the FESS and hybrid groups. CONCLUSION: BCD, especially in the office, has risen in popularity since the introduction of Current Procedural Terminology codes in 2011. This study reveals significant differences in demographics and comorbidities between patients undergoing BCD and those undergoing FESS. Such disparities may highlight the need for better-defined indications for use of this technology.
