What 35700 covers

Code 35700 captures the added work of operating again on a previously placed bypass graft. Vascular surgeons report it when a new operation requires reentry into a prior bypass-graft operative field; it is not the primary code for the definitive procedure. The operative record should identify the existing graft, explain why another operation was needed, and describe the reoperative work performed. The service is associated with operative treatment of bypass-graft problems, not a routine office encounter.

Report 35700 only with the CPT code for the primary operation; it cannot stand alone. Select that primary code for the actual procedure performed, such as an appropriate lower-extremity bypass operation, and report 35700 when the record supports reoperation on the graft. CMS treats it as an add-on code paid within the primary procedure's global period. The operative report should connect the prior graft, the repeat operative work, and the definitive service represented by the primary code.

How to choose

35703Artery explorationLower extremity, no repair
This code describes lower-extremity artery exploration that is not followed by repair. Code 35700 is for reoperation involving a bypass graft and is reported with a primary procedure.
35875Graft thrombectomyWithout graft revision
This code describes thrombectomy of an arterial or venous graft without graft revision. Code 35700 reports reoperative work as an add-on, not thrombectomy itself.
35876Graft thrombectomyWith graft revision
This code describes graft thrombectomy with revision. Use it for that work; 35700 is add-on reporting for reoperation involving a bypass graft.

35700 billing questions

Can 35700 be reported by itself?

No. It is an add-on code and must be submitted with the primary procedure performed during the reoperation.

How do I choose the primary procedure?

Code the definitive operation actually performed. For example, 35556 or 35656 may represent a femoral-popliteal bypass, depending on the graft used and the procedure performed.

How is 35700 different from 35703?

Code 35703 describes exploration of a lower-extremity artery that is not followed by surgical repair. Code 35700 is add-on reporting for reoperation involving a bypass graft.

Is 35700 the code for graft thrombectomy?

No. Codes 35875 and 35876 describe thrombectomy of an arterial or venous graft, without or with graft revision, respectively. Choose codes based on the work performed.

What documentation supports 35700?

Document the existing bypass graft, the reason for returning to the operative field, the reoperative work performed, and the primary procedure completed.
