Billing modifier · CMS claims manual
Modifier 54: the surgery, without the postoperative care.
Modifier 54 reports surgical care only: the surgeon performed the procedure but another physician, by agreement, provides the postoperative management. The matching modifier for the receiving physician is 55. Both claims carry the same date of service and the same surgical code.

What CMS says
CMS chapter 12, section 40.2.A.3: where physicians agree on the transfer of care during the global period, “-54” is used for surgical care only and “-55” for postoperative management only. The two bills contain the same date of service and the same surgical procedure code, distinguished by the modifier.
The claim does not have to say that care was transferred, but the date care was relinquished or assumed must be shown in the remarks field or free text segment. The surgeon and the receiving physician must each keep a copy of the written transfer agreement in the beneficiary’s medical record.
Dates and localities
A surgeon who relinquishes care at discharge need only show the date of surgery. If the surgeon also cared for the patient for a period after discharge, the surgeon shows the date of surgery and the date care was relinquished (Item 19 on the paper CMS-1500).
If the surgery is in one payment locality and the postoperative care in another, the surgery is billed with modifier 54 to the A/B MAC serving the locality where it was performed. The sums paid in two localities will not equal the global amount because of geographic adjustments.
Limits
Occasional post-discharge services by a physician other than the surgeon, with no transfer of care, are reported with an evaluation and management code and no modifier. Physicians in the same group practice that bills the global package under reassigned benefits bill the whole package. Private payers may follow the same split or not; confirm with the payer.
Look-alike modifiers
- Modifier 55: The receiving physician’s postoperative management.
- Modifier 58: Staged or related procedure in the global period.
