Adenoidectomy is a common otolaryngologic procedure that may be performed with concomitant tonsillectomy (T&A). This study investigates differences between pediatric inpatients undergoing adenoidectomy alone and T&A. The 2016 Kid's Inpatient Database was used to identify pediatric patients undergoing adenoidectomy (ICD-10: 0CTQXZZ) with and without tonsillectomy (ICD-10: 0CTP, 0CBP). Common comorbidities, postoperative complications, and procedures undergone were identified via ICD-10 codes. Univariate and multivariable analyses were performed to determine statistical associations with tonsillectomy status. Of the 5,540 inpatients who met inclusion criteria, the majority underwent T&A (88.9%). Mean patient age was 4.9 years. On multivariable analysis adjusting for patient demographics, hospital data, and severity of illness, T&A patients had similar total charges (5,442 vs. 8,577,
