What 28232 covers
The surgeon makes an incision and divides one flexor tendon in a toe to reduce a deforming pull or contracture. Orthopedic surgeons and podiatric surgeons commonly perform this procedure for a toe deformity in an operating room or other surgical setting. The defining details are an open approach, a flexor tendon, and one tendon in a toe; this is not repair of a damaged tendon or incision of an extensor tendon.
Select the code from the operative note’s documented tendon, toe, approach, and number of tendons treated. The note should support the deformity or contracture addressed and the specific tendon division. Medicare 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 others at 50%. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.

- 28272Toe joint releaseInterphalangeal joint, each
- 28272 addresses release of a toe joint contracture. 28232 divides a flexor tendon, so distinguish the structure treated.

28232 billing questions
How is 28232 different from 28230?
28232 is for open division of a flexor tendon in a toe. 28230 describes an open incision of a single extensor tendon.
When would 28234 be considered instead?
28234 is for open incision of multiple extensor tendons. Choose based on the tendon type and number documented, not simply because more than one toe is treated.
Can 28232 be separately reported with hammertoe correction?
Do not assume the tendon division is separately reportable when it is part of a broader hammertoe correction. Check applicable edits and document any distinct work supporting separate reporting.
Should modifier 50 be used when both feet are treated?
No. CMS identifies bilateral adjustment as inappropriate for this code. The descriptor and anatomy do not support modifier 50.
What documentation supports this code?
Record the affected toe, the flexor tendon divided, the open approach, the number of tendons treated, and the deformity or contracture addressed.
What global and multiple-procedure rules apply?
The code has a 90-day global period. For multiple procedures in the same session, Medicare pays the highest-valued procedure in full and the others at 50%.
