What 27185 covers

An orthopedic surgeon uses this service to correct persistent or residual malalignment of the femoral epiphysis, commonly in a patient with deformity after a slipped capital femoral epiphysis. The correction may involve an osteotomy or another realignment method. The operative report should identify the epiphyseal deformity, the corrective work performed, and the resulting alignment; the code is for surgical revision, not simply an evaluation of hip pain or imaging of the growth plate.

Report the code when the procedure revises the femoral epiphysis, rather than treating an active slip by a method represented by the slipped-epiphysis treatment codes. Documentation should describe the indication, operative approach, and specific correction. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures 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 is statutorily restricted; co-surgeons are paid only with 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

27175Slipped epiphysis treatment
27175 represents closed treatment of a slipped femoral epiphysis without manipulation. Use 27185 for surgical revision to correct epiphyseal malalignment, not for that closed treatment.
27178SCFE surgery
27178 represents open treatment of a slipped femoral epiphysis with internal fixation. Distinguish treatment of the slip from revision of residual deformity.
27179Femoral osteotomy
27179 concerns revision of the femoral head or neck. Select 27185 when the operative work revises the femoral epiphysis; follow the documented target and procedure.

27185 billing questions

How is this different from treatment of a slipped femoral epiphysis?

This code describes revision to correct epiphyseal malalignment. Select a slipped-epiphysis treatment code when the service treats the slip itself using the method represented by that code.

Does the code include routine postoperative visits?

Yes. Its 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

How does CMS handle bilateral reporting?

When the procedure is performed on both sides and reported with modifier 50, CMS pays at 150%.

Can an assistant-at-surgery or co-surgeon be reported?

Assistant-at-surgery payment is subject to a statutory restriction. Co-surgeons are paid only when supporting documentation is provided.

What should the operative note support?

Document the femoral epiphyseal deformity, why revision was required, and the corrective method and realignment performed.
