Clinical & Coding Specifications
Clinical Context
A typical patient is a child under 12 years old presenting with recurrent tonsillitis, obstructive sleep-disordered breathing due to tonsillar hypertrophy, or chronic tonsillar disease refractory to medical therapy. The clinical workflow begins with evaluation by a pediatrician or pediatric otolaryngologist documenting history of recurrent throat infections (frequency, severity), sleep symptoms (snoring, witnessed apneas), physical exam showing enlarged tonsils, and failure of medical management. Preoperative assessment includes anesthesia evaluation, informed consent, review of bleeding history and medications, and appropriate labs if indicated. The procedure is performed in an ambulatory surgery center or hospital operating room under general endotracheal anesthesia. Postoperative care includes monitoring in the PACU, pain control (acetaminophen/ibuprofen, opioid-sparing strategies), hydration, and discharge instructions to caregivers with return precautions for hemorrhage or airway compromise. Follow-up with the surgeon is arranged to assess healing and address any complications.
