What 42825 covers

An otolaryngologist typically performs this operation in an operating room, removing the palatine tonsils in a patient younger than 12. Common clinical reasons include recurrent or chronic tonsillitis and enlarged tonsils associated with obstructive breathing or sleep-disordered breathing. The operation addresses the tonsils; removal of adenoid tissue is a separate distinction in code selection.

Select this code based on the patient’s age on the date of surgery and the documented procedure. The operative report should support removal of the palatine tonsils and identify any additional procedure, such as adenoid removal. This major surgery includes the preoperative visit on the day before and related postoperative care for 90 days. For multiple procedures in the same session, CMS pays the highest-valued procedure in full and other procedures at 50%. Do not append modifier 50. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
