What 27475 covers
This procedure arrests growth at the distal femoral physis, the growth plate near the knee. Pediatric orthopedic surgeons commonly perform it for a skeletally immature patient when growth prediction indicates that one leg is likely to become longer than the other. The treatment plan targets the physis of the longer limb so continued growth of the opposite leg can reduce the discrepancy. The code is specific to the distal femur; growth arrest at another site is represented by a different code.
Report the procedure for treatment of the distal femoral growth plate, supported by documentation of the treated site, laterality, indication, and growth-management plan. This major surgery has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral treatment with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons require supporting documentation, and team surgery is not permitted.

27475 billing questions
How is this code distinguished from other growth-arrest codes?
This code identifies epiphysiodesis at the distal femur. Select the related code for the specific proximal or distal tibial site when that physis is treated instead.
What documentation supports reporting this procedure?
Document the distal femoral physis treated, side, clinical indication, and the growth-management plan. The record should support why arresting growth at that site is part of the patient's treatment.
Are related postoperative visits separately included?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
How is bilateral treatment paid?
When the procedure is performed bilaterally and reported with modifier 50, CMS pays it at 150%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment is barred by statutory restriction. Co-surgeons are paid only when supporting documentation is provided.
What happens when another procedure is performed in the same session?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
