Knee surgery
About 27412: Autologous chondrocyte implantation of knee
Reports implantation of a patient’s cultured cartilage cells to treat a focal knee articular-cartilage defect, including the cartilage harvest and implantation stages.
This procedure treats a focal articular-cartilage defect by implanting cartilage cells taken from the same patient and expanded in culture. An orthopedic surgeon harvests cartilage for the cell preparation, then performs the implantation at a later stage, commonly through an arthrotomy. The treatment is directed at a localized cartilage lesion rather than generalized knee arthritis or a loose cartilage fragment.
Report the code for the autologous cell implantation service; cartilage harvest and the arthrotomy needed for implantation are included, not separately coded as independent procedures. The operative record should establish the focal defect, the autologous cell technique, and the implantation performed. CMS assigns a 90-day major-surgery global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.

27412 billing questions
How is this different from an osteochondral graft?
This procedure implants the patient’s cultured cartilage cells. Osteochondral graft procedures transfer a piece of cartilage with underlying bone, using donor tissue or tissue harvested from the patient.
Can the cartilage harvest be billed separately?
No. The harvest for the cell preparation is included in this implantation service, as is the arthrotomy needed to implant the cells.
What documentation supports reporting this code?
Document the focal articular-cartilage defect, the autologous cell technique, the implantation, and the operative details. The record should also support the cartilage harvest associated with the cell preparation.
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. Unrelated services or separately identifiable procedures require their own documentation and coding.
How are bilateral procedures and multiple procedures handled?
CMS pays bilateral reporting with modifier 50 at 150%. For multiple procedures performed in the same session, the highest-valued procedure is paid in full and the others at 50%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team-surgery payment is not permitted for this code.
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.
