What 27358 covers
This add-on captures internal fixation performed with operative treatment of a femoral bone lesion, such as curettage or excision of a benign lesion when the bone needs stabilization. An orthopedic surgeon typically performs the work in an operating room, placing fixation as part of the same operative treatment. The fixation supports the treated segment; this code is not a stand-alone report for fixation unrelated to femoral lesion removal.
Report 27358 with the applicable primary femoral lesion procedure, such as 27355, when the operative record supports both lesion treatment and internal fixation. Documentation should identify the femoral lesion, describe the curettage or excision, and establish that fixation was performed as part of the treatment. CMS classifies the code as an add-on: it must be billed with a primary procedure, and payment falls within that procedure’s global period.

How to choose
- 27355Femur lesion removal
- 27355 reports the primary femoral lesion treatment. Add 27358 only when internal fixation is also performed as part of that treatment.
- 27356Bone lesion surgery
- 27356 is a related femoral lesion procedure variant involving grafting; 27358 captures fixation as an add-on to the primary procedure.
- 27365Bone tumor resection
- 27365 describes resection of a femoral or knee tumor. 27358 is for fixation accompanying the applicable femoral lesion procedure, not tumor resection by itself.
27358 billing questions
Can 27358 be billed by itself?
No. It is an add-on code and must be reported with the applicable primary procedure for femoral lesion treatment.
When is 27358 appropriate with 27355?
Report it when the femoral lesion procedure includes internal fixation. The operative note should support both lesion treatment and fixation.
Does lesion removal alone support 27358?
No. The add-on represents fixation performed with the lesion procedure; lesion removal without fixation does not support it.
What documentation supports the fixation add-on?
Document the femoral lesion procedure and the internal fixation performed as part of that treatment. The code is paid within the primary procedure’s global period.
