What 60225 covers
The surgeon removes an entire thyroid lobe and part, but not all, of the lobe on the other side. This operation may be selected for bilateral nodular disease when the planned resection differs between sides. It is generally performed in an operating room by a surgeon treating thyroid disease, often in a hospital or other facility setting.
Report one unit for the combined operation, supported by an operative note identifying the side and extent of resection on each side. The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days. 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% reduction. Modifier 50 is inappropriate for this code. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

- 60240ThyroidectomyTotal gland removal
- 60240 represents removal of the entire thyroid. 60225 leaves thyroid tissue on the side treated with a subtotal resection.
60225 billing questions
How does this differ from 60220?
60220 describes complete removal of one thyroid lobe, with or without the isthmus. Use 60225 when the opposite lobe is also partially removed.
When is 60212 a closer fit?
60212 describes partial removal on one side with subtotal removal on the opposite side. The distinction is whether the first-side lobectomy is total or partial.
Should modifier 50 be appended because both sides are operated on?
No. CMS identifies bilateral adjustment as inappropriate for this code; the opposite-side resection is already part of the described operation.
What should the operative note document?
Document which lobe was completely removed and how much thyroid tissue was removed from the opposite lobe. This supports choosing 60225 rather than a one-sided or partial-lobectomy code.
How is the 90-day global period applied?
The day-before preoperative visit and related postoperative care during the 90 days after surgery are included in the global period.
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.
