About 20933: Partial hemicortical allograft reconstruction
Reports partial hemicortical allograft reconstruction of a bone defect, commonly after tumor resection, when part of the host bone’s cortex is replaced.
This add-on describes reconstruction of a bone defect with a donor-derived graft that replaces part of the cortical circumference while retaining the remaining host bone. It is most often associated with orthopedic oncology, such as reconstruction after removal of a bone tumor in a long bone. The orthopedic surgeon shapes and secures the graft to restore structural continuity at the resection site.
Report it with the primary operation that created and reconstructs the defect; it is not submitted alone. The operative report should establish that a partial hemicortical allograft was used and identify the reconstructed bone and defect. Distinguish this from a graft replacing an entire intercalary segment or a joint-bearing surface. CMS classifies the service as an add-on paid within the primary procedure’s global period.

20933 billing questions
Can 20933 be reported without a primary procedure?
No. It is an add-on code and must be reported with the primary operation for the bone defect.
How is 20933 distinguished from 20934?
Use 20933 for partial hemicortical reconstruction. Code 20934 describes reconstruction with a complete intercalary segment.
When would 20932 be considered instead?
20932 applies to an osteoarticular allograft reconstruction involving a joint-bearing surface, rather than a partial cortical segment.
What documentation supports reporting 20933?
The operative report should identify the allograft, the bone and defect reconstructed, and that the reconstruction replaced only part of the cortical circumference.
How does the global period affect this add-on?
CMS payment for 20933 falls within the global period of the primary procedure. Report it with that procedure rather than as a stand-alone service.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
