What 28086 covers

This procedure removes abnormal tissue from a tendon sheath in the foot, often when a ganglion arises from or involves the sheath. An orthopedic surgeon or podiatric surgeon typically performs the excision in an operating room or ambulatory surgery setting. The operative report should identify the tendon and foot location, describe the sheath tissue removed, and clarify whether the target was a sheath-associated lesion rather than a joint, nerve, or separate soft-tissue mass.

Report 28086 for the primary tendon sheath excision; 28088 is the add-on code for an additional sheath. The service has 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 the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeons require supporting documentation, and team surgery is 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.

28086 billing questions

When is 28086 used instead of 28088?

Use 28086 for the primary tendon sheath excision. Use 28088 for each additional sheath excised in the same operative session.

Is a tendon sheath ganglion included in this procedure?

Yes, a ganglion arising from or involving a foot tendon sheath is a typical reason for excision. The operative note should establish the sheath relationship and tissue removed.

How does 28086 differ from tendon incision codes 28010 and 28011?

28086 reports excision of tendon sheath tissue. Codes 28010 and 28011 describe tendon incision or release, not removal of the sheath.

What documentation supports reporting 28086?

Document the foot and tendon location, the sheath or sheath-associated lesion excised, and the extent of removal. If another sheath is excised, identify it to support the additional-sheath code.

What global and multiple-procedure payment rules apply?

The code has a 90-day global period. When procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%.

Can modifier 50 or an assistant-at-surgery service be reported?

Bilateral reporting with modifier 50 is paid at 150%, and assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation.

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.
