What 28400 covers
This service covers nonoperative treatment of a heel bone fracture when the treating clinician manages the fracture without manipulating it to change its alignment. An orthopedic surgeon or podiatrist may provide care in an office, emergency department, or outpatient setting. Treatment commonly includes immobilization in a cast or boot and planned clinical and imaging follow-up. The key distinction is the treatment performed, not simply whether the fracture is displaced on imaging.
Report the code when the documented plan and service support closed fracture care without manipulation. The record should identify the calcaneal fracture and show that manipulation or fixation was not performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are paid at 50%. For bilateral treatment with modifier 50, payment is 150%. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.

28400 billing questions
How is this different from 28405?
Use 28400 when the calcaneal fracture is treated without manipulation. Code 28405 describes closed treatment that includes manipulation.
When would 28406 be more appropriate?
Code 28406 is for percutaneous skeletal fixation of a calcaneal fracture with manipulation. It is not the code for immobilization alone without manipulation or fixation.
Can casting or boot application be billed separately?
Routine immobilization is part of the fracture treatment service. Do not separately report routine cast or boot application for the same fracture care.
What documentation supports reporting 28400?
Document the calcaneal fracture, the treatment plan, and that the fracture was managed without manipulation. The record should support that fracture care was provided, rather than imaging or an evaluation alone.
How is bilateral treatment reported?
For bilateral calcaneal fracture treatment, report modifier 50; CMS pays the bilateral procedure at 150%.
Can an assistant or co-surgeon be reported?
Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
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.
