What 28300 covers
A calcaneal osteotomy cuts and repositions part of the heel bone to change hindfoot alignment. Orthopedic foot-and-ankle surgeons and podiatric surgeons may perform it for deformities such as a varus heel in cavovarus or a valgus heel in flexible flatfoot. The approach may shift or reshape the bone, with fixation used as needed to maintain the correction. The operative report should establish that the calcaneus itself was cut and describe the correction and side treated.
Report this code for the heel-bone osteotomy, not an osteotomy of the ankle or other tarsal bones. It has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For same-session procedures subject to the multiple-procedure rule, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.

28300 billing questions
How is this code distinguished from an osteotomy of another foot bone?
Use it when the bone cut and realignment involve the calcaneus. An osteotomy of the ankle bone or other tarsal bones is represented by a different code.
What documentation supports reporting this code?
The operative report should identify the calcaneus and side, the deformity being addressed, and the bone cut and realignment performed.
Does the 90-day global period include related postoperative care?
Yes. CMS includes the day-before preoperative visit and 90 days of related postoperative care in the major-surgery global period.
How is bilateral surgery paid?
When the procedure is reported bilaterally with modifier 50, CMS pays at 150%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team-surgery payment is not permitted.
