Modifier 54
Complete guide to Modifier 54 — Surgical Care Only. Learn how Modifier 54 works within the global surgical package, when care is transferred, how to distinguish Modifiers 54, 55 and 56, and how AR callers can resolve common global surgery billing denials.
Modifier 54 at a Glance
The key concepts every medical biller and AR caller should understand.
Modifier
Surgical Care Only.
Surgical Component
Identifies the surgical portion of a global surgical package when the practitioner does not furnish the full global package.
Global Surgery
CMS expanded the applicability of Modifier 54 for 90-day global surgical packages beginning with the CY 2025 policy.
Transfer of Care
Modifier 54 works alongside other transfer-of-care modifiers such as 55 and 56 when applicable.
What Is Modifier 54?
Understand the concept before working with claims.
Simple Definition
Modifier 54 = Surgical Care Only
Modifier 54 identifies the surgical component of a global surgical package when the practitioner provides surgical care but does not provide the complete postoperative portion of the global package.
CMS describes Modifier 54 as the modifier used for surgical care only when care is transferred or the practitioner expects to furnish only the surgical portion of the applicable global package. :contentReference[oaicite:2]{index=2}
Easy Way to Remember
Surgeon performs surgery
+
Another practitioner handles postoperative care
=
Modifier 54 may identify the surgical-care-only portion, when applicable.
Important Medicare Update
CMS finalized a policy beginning in CY 2025 to broaden the applicability of Modifier 54 to all 90-day global surgical packages when a practitioner expects to furnish only the surgical portion of the global package.
CMS explains that this includes situations beyond a formal, documented transfer of care, including an informal, non-documented but expected transfer of care. :contentReference[oaicite:3]{index=3}
For 2026 billing, always verify the current CMS guidance, applicable CPT code and payer-specific processing rules.
Understanding the Global Surgical Package
Modifier 54 makes much more sense once you understand the global surgery concept.
Preoperative Care
Services furnished before the surgical procedure may be included in the global package according to the applicable global surgery rules.
Surgical Care
The actual surgical procedure is the central component identified by Modifier 54 when only surgical care is furnished.
Postoperative Care
Postoperative management may be furnished by another physician or practitioner and reported using Modifier 55 when applicable.
How Transfer of Care Works
The simplest way to understand Modifier 54 is to visualize the division of responsibility.
Surgeon
Performs the surgical procedure.
CPT-54Receiving Practitioner
Provides postoperative management when applicable.
CPT-55Important CMS Claim Detail
CMS states that when physicians agree on a transfer of care during the global period, the surgical-care-only claim and postoperative-care claim use the same date of service and same surgical procedure code, distinguished by the appropriate modifiers. :contentReference[oaicite:4]{index=4}
Modifier 54 vs 55 vs 56
These three modifiers represent different components of the global surgical package.
| Modifier | Meaning | Who Uses It? | Main Concept |
|---|---|---|---|
| 54 | Surgical Care Only | Practitioner performing surgery | Surgical component only |
| 55 | Postoperative Management Only | Practitioner providing postoperative care | Postoperative component only |
| 56 | Preoperative Management Only | Practitioner providing preoperative management | Preoperative component only |
Memory Trick
54 = Surgery
55 = Post-op
56 = Pre-op
CMS’s Global Surgery booklet identifies these as the transfer-of-care modifiers. :contentReference[oaicite:5]{index=5}
When Should Modifier 54 Be Used?
Use a decision-based workflow instead of automatically adding Modifier 54.
When Modifier 54 Should Not Be Used Automatically
Full Global Care Furnished
If the practitioner furnishes the complete applicable global package, Modifier 54 should not be added simply to change payment.
No Surgical Service
Modifier 54 identifies surgical care only. It is not a substitute for a surgical procedure code.
Postoperative Care Only
A practitioner providing postoperative management should evaluate Modifier 55 rather than Modifier 54.
Preoperative Care Only
Preoperative management may involve Modifier 56 when applicable.
Unsupported Transfer
Do not assume a transfer arrangement exists without reviewing the actual documentation and applicable payer requirements.
Wrong Date or Code
Incorrect dates or mismatched surgical procedure codes can cause claim processing problems.
Modifier 54 Examples
Educational examples. Always verify the applicable CPT code, global period and payer policy.
Dr. A performs the surgical procedure. Another physician assumes responsibility for postoperative management.
The surgical provider may report the applicable procedure with Modifier 54 when the requirements are met.
CPT-54The receiving physician may report the applicable postoperative service with Modifier 55 when appropriate.
The surgeon performs the procedure but expects another practitioner to provide postoperative care.
For applicable Medicare 90-day global packages, CMS broadened Modifier 54 beginning in CY 2025 to cover situations involving an expected transfer of care, including informal expected transfers.
CPT-54Dr. B did not perform the surgery but assumes responsibility for postoperative management.
The receiving practitioner evaluates whether Modifier 55 applies.
CPT-55A practitioner provides preoperative management while another practitioner performs the surgery.
Modifier 56 may apply when the applicable requirements are met.
CPT-56Modifier 54 Claim Example
A simplified educational example of how the surgical and postoperative claims can be distinguished.
| Provider | Date of Service | Procedure | Modifier | Responsibility |
|---|---|---|---|---|
| Surgeon | Same surgical DOS | Same surgical CPT | 54 | Surgical care only |
| Post-op Physician | Same surgical DOS | Same surgical CPT | 55 | Postoperative management |
CMS Reminder
CMS specifically provides examples in which the surgeon reports the same procedure code with Modifier 54 and the postoperative-care physician reports the same procedure code with Modifier 55 on the same date of service. :contentReference[oaicite:6]{index=6}
Common Modifier 54 Denials
Common issues that can create global surgery claim processing problems.
Modifier Not Supported
The payer determines that the claim does not support surgical-care-only reporting.
Incorrect Global Surgery Reporting
The payer identifies a mismatch between the global surgery arrangement and the submitted modifier.
Same Procedure / Date Issue
The surgical and postoperative claims may contain inconsistent procedure codes or dates.
Post-op Care Conflict
The payer identifies postoperative care as being included or assigned differently within the claim.
Transfer Documentation
Documentation may not adequately support the transfer or expected transfer of care.
Global Period Conflict
The payer identifies another global surgery service or reporting conflict.
How to Work a Modifier 54 Denial
Practical AR workflow for medical billing teams.
Review the Claim
Verify DOS, surgical CPT/HCPCS, Modifier 54, units, POS, rendering provider and payer.

Common Modifier 54 Mistakes
01. Confusing 54 and 55
Modifier 54 represents surgical care only. Modifier 55 represents postoperative management only.
02. Ignoring the Global Period
The global surgery rules must be reviewed before determining how care should be reported.
03. Wrong Date of Service
CMS guidance states that the surgical and postoperative claims use the same surgical date of service in the applicable transfer-of-care situation.
04. Mismatched Surgical CPT
The claims may need to use the same surgical procedure code when reporting the transferred global components.
05. Assuming Transfer Always Means 54
Verify the actual circumstances, global period, payer and current Medicare policy.
06. Using 54 to Change Payment
Modifier 54 communicates the component of care furnished. It should not be used solely to obtain a desired payment amount.
Modifier 54 Denial Root-Cause Analysis
Wrong Modifier
The service may actually represent postoperative or preoperative management.
Global Package Conflict
Another claim may have been processed as the complete global surgical package.
Documentation Gap
The record may not support the transfer or expected transfer of care.
Payer Rule
The payer may apply specific requirements for global surgery and transfer-of-care reporting.
