Tonsillectomy: CPT code and Medicare rate

Removal of the tonsils together with the adenoids in a patient under 12, done for recurrent throat infections or for airway obstruction from enlarged tissue.

Also called: tonsil removal, tonsils out, tonsillectomy and adenoidectomy.

Usually billed as

42820 Tonsillectomy and Adenoidectomy, Under Age 12
Office (non-facility)
$260.86
Facility
$260.86

National amounts for the Q3 2026 release (July 1 – September 30, 2026), using geographic index values of 1.000. Your local rate differs — open the code page for the locality breakdown.

The code depends on the patient's age and on whether the adenoids come out too, so an adult tonsillectomy is reported differently.
