What 42826 covers

This code describes surgical removal of the palatine tonsils in a patient who is at least 12 on the date of surgery. Otolaryngologists commonly perform the procedure in a hospital or ambulatory surgery center, often for recurrent tonsillar infections or obstructive tonsillar enlargement. It covers tonsil removal without the adenoidectomy included in a combined tonsil-and-adenoid procedure.

Choose the age-specific code based on the patient’s age on the service date; use the under-12 tonsillectomy code for younger patients. The operative report should support removal of the palatine tonsils and document the indication and any concurrent adenoid procedure. Medicare includes the day-before preoperative visit and 90 days of related postoperative care in the major-surgery global period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

42826 billing questions

How does this code differ from 42825?

42826 is for tonsil removal when the patient is age 12 or older on the date of surgery. 42825 is the age-specific code for patients younger than 12.

Should modifier 50 be appended for removal of both tonsils?

No. The code represents the tonsillectomy, and CMS identifies bilateral adjustment as inappropriate.

Which code applies when the adenoids are removed too?

Use the age-appropriate combined tonsil-and-adenoid code when both are removed: 42821 for a patient age 12 or older, or 42820 for a younger patient.

Does the global period include postoperative visits?

Yes. The 90-day major-surgery global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.

Can an assistant surgeon or co-surgeon be paid for this procedure?

Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.

What happens if another procedure is performed in the same session?

The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction when performed in the same session.
