What 42870 covers

An otolaryngologist removes lingual tonsil tissue at the base of the tongue, usually in an operating-room setting. The service may be performed for enlarged lingual tonsils associated with airway obstruction, including in a patient being evaluated or treated for obstructive sleep apnea. The operative report should identify the lingual tonsil as the target and describe the excision; removal of palatine tonsils or a biopsy of throat tissue is a different service.

Report this code when lingual tonsil tissue is excised, not when tissue is only sampled. Documentation should establish the operative site and extent of removal. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. 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 for this code. Assistant-at-surgery payment requires documented medical necessity; 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.

42870 billing questions

How is this different from palatine tonsillectomy?

This code is for lingual tonsil tissue at the tongue base. Palatine tonsillectomy codes apply to the tonsils on the sides of the throat.

Can this code be used for a biopsy?

No. It reports excision of lingual tonsil tissue. A throat-tissue biopsy is a different service when the intent is diagnostic sampling rather than removal.

Should modifier 50 be appended for both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 should not be used.

How are other procedures in the same session paid?

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

When may an assistant at surgery be reported?

Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted for this code.

What postoperative care is included?

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

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
