What 28045 covers
A foot or ankle surgeon, often an orthopedic surgeon or podiatrist, uses this code for excision of a small mass in the foot or toe that lies in deeper tissue rather than being confined to the subcutaneous layer. The service involves surgically exposing and removing the lesion; the setting may be an operating room or an office procedure setting, depending on the case and resources needed.
Select this code when the documented lesion is in the foot or toe, is deep, and measures less than 1.5 cm. The operative report should identify the site, depth, lesion size, and removal performed; pathology findings may further describe the specimen. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

28045 billing questions
How does this code differ from 28043?
Use 28045 for a deep lesion under 1.5 cm. Code 28043 is for a lesion of that size confined to the subcutaneous layer.
Does lesion size refer to the incision?
No. Document the size of the lesion, along with its depth and foot or toe location; the incision length does not establish the size category.
When should 28041 be considered instead?
Use 28041 for a deep foot or toe lesion measuring 1.5 cm or greater. The distinction from 28045 is the documented lesion size.
How is bilateral surgery reported?
For bilateral procedures, report modifier 50; CMS pays this code at 150% under the stated bilateral rule.
Are routine postoperative visits separately included?
Related postoperative care during the 90-day global period is included, as is the day-before preoperative visit.
Can an assistant surgeon be paid for this procedure?
Assistant-at-surgery payment is available only with documentation of medical necessity. Co-surgeons and team surgery are not permitted.
