What 42140 covers
An otolaryngologist removes uvular tissue when the uvula itself is the target of treatment, such as an isolated excision for symptomatic elongation or irritation. The procedure may be performed in an operating room or an appropriately equipped procedure setting, depending on the planned surgery and patient. When uvular removal is part of a broader palate and pharyngeal operation, the overall procedure may be represented by a different code rather than an isolated excision.
Select 42140 when the operative service is excision of the uvula, not merely sampling a lesion or destroying it. The operative note should identify the uvula as the site, describe the tissue removed, and establish the reason for excision. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate; assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.

How to choose
- 42145PalatopharyngoplastyPalate and pharynx repair

- 42100Palate biopsyTissue sampling
- 42100 describes biopsy of the palate for diagnostic sampling; 42140 represents excision of uvular tissue as treatment.
- 42160Palate lesion treatmentDestruction method
- 42160 is for treatment of a mouth-roof lesion by destruction. 42140 is used when uvular tissue is surgically excised.
- 42120Palate resectionExtensive lesion or palate
- 42120 is relevant to a more extensive palate resection. 42140 is limited to excision of the uvula.
42140 billing questions
When should 42140 be chosen instead of 42145?
Use 42140 for excision focused on the uvula. When the operation includes broader palate or pharyngeal repair, evaluate 42145 instead of treating the uvular work as a separate service automatically.
Can 42140 be reported with a biopsy code?
A diagnostic sampling service and a therapeutic excision are different services. The record should show that a distinct biopsy was performed; do not report a biopsy merely because the excised tissue was sent for pathology.
Is modifier 50 appropriate for this code?
No. The CMS bilateral adjustment does not apply to 42140, and modifier 50 is inappropriate for this anatomy and descriptor.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant surgeon or co-surgeon be paid?
CMS applies a statutory restriction to assistant-at-surgery payment for this code. Co-surgeons and team surgery are not permitted.
How is 42140 affected when other procedures are done in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50% when performed in the same session.
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.
