What 27700 covers

This code describes an operation to revise the ankle joint. It is generally performed by an orthopedic surgeon, often a foot-and-ankle specialist, in an operating room when the operative plan is to revise a prior ankle-joint procedure. The record should make clear what prior procedure or joint condition is being addressed and what revision work the surgeon performed; an isolated implant removal or a primary reconstruction represents a different service.

Select the code based on the procedure actually performed, not simply a diagnosis of ankle pain or a history of surgery. The operative report should identify the ankle joint, the reason for revision, and the specific revision work. CMS 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 one session, the highest-valued is paid in full and other eligible procedures at 50%. Modifier 50 pays bilateral procedures at 150%. Assistant-at-surgery services may be paid; co-surgeon payment requires 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.

How to choose

27702Ankle replacement
Choose 27700 for revision of the ankle joint. Code 27702 describes a reconstructive ankle-joint procedure, so the operative work determines the choice.
27703Ankle revision
This is another ankle-joint procedure in the same nearby code group. Compare the documented procedure with the service represented by 27700 rather than relying on the shared joint site.
27704Ankle implant removal
Code 27704 is for removal of an ankle implant. Use 27700 when the operation revises the ankle joint rather than performing implant removal alone.

27700 billing questions

How do I distinguish this from an ankle reconstruction code?

Use this code when the documented operation revises the ankle joint. The reconstruction codes describe a different operative service; base selection on the procedure performed, not the diagnosis alone.

Is isolated ankle implant removal reported with this code?

No. Code 27704 describes removal of an ankle implant. The operative report should support whether the service was revision of the joint or removal alone.

What documentation supports reporting this code?

Document the ankle joint involved, the reason for revision, relevant prior ankle-joint surgery, and the revision work performed.

How does the 90-day global period affect postoperative billing?

The day-before preoperative visit and 90 days of related postoperative care are included in the global period.

How are bilateral procedures and multiple procedures paid?

A bilateral procedure reported with modifier 50 is paid at 150%. For multiple procedures in the same session, the highest-valued procedure is paid in full and others at 50%.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery services may be paid. Co-surgeons are paid only when supporting documentation is provided; team surgery is not permitted.

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.
