Surgical Care Only

Modifier 54 at a Glance

The key concepts every medical biller and AR caller should understand.

54

Modifier

Surgical Care Only.

SURG

Surgical Component

Identifies the surgical portion of a global surgical package when the practitioner does not furnish the full global package.

90D

Global Surgery

CMS expanded the applicability of Modifier 54 for 90-day global surgical packages beginning with the CY 2025 policy.

55

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.

PRE

Preoperative Care

Services furnished before the surgical procedure may be included in the global package according to the applicable global surgery rules.

OR

Surgical Care

The actual surgical procedure is the central component identified by Modifier 54 when only surgical care is furnished.

POST

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.

54

Surgeon

Performs the surgical procedure.

CPT-54
55

Receiving Practitioner

Provides postoperative management when applicable.

CPT-55

Important 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.

1 Is the procedure part of a global surgical package?
2 Is the practitioner providing only the surgical portion of the global package?
3 Is postoperative care expected to be provided by another practitioner?
4 Does the applicable Medicare/payer policy permit Modifier 54 for the service?
5 Is the date of service and surgical procedure code reported consistently by the involved providers?
6 Is the transfer or expected transfer properly documented when required?

When Modifier 54 Should Not Be Used Automatically

01

Full Global Care Furnished

If the practitioner furnishes the complete applicable global package, Modifier 54 should not be added simply to change payment.

02

No Surgical Service

Modifier 54 identifies surgical care only. It is not a substitute for a surgical procedure code.

03

Postoperative Care Only

A practitioner providing postoperative management should evaluate Modifier 55 rather than Modifier 54.

04

Preoperative Care Only

Preoperative management may involve Modifier 56 when applicable.

05

Unsupported Transfer

Do not assume a transfer arrangement exists without reviewing the actual documentation and applicable payer requirements.

06

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.

Example 1 — Surgeon Transfers Post-op Care

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-54

The receiving physician may report the applicable postoperative service with Modifier 55 when appropriate.

Example 2 — Expected Transfer

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-54
Example 3 — Post-op Provider

Dr. B did not perform the surgery but assumes responsibility for postoperative management.

The receiving practitioner evaluates whether Modifier 55 applies.

CPT-55
Example 4 — Pre-op Only

A practitioner provides preoperative management while another practitioner performs the surgery.

Modifier 56 may apply when the applicable requirements are met.

CPT-56

Modifier 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.

Denial 01

Modifier Not Supported

The payer determines that the claim does not support surgical-care-only reporting.

Denial 02

Incorrect Global Surgery Reporting

The payer identifies a mismatch between the global surgery arrangement and the submitted modifier.

Denial 03

Same Procedure / Date Issue

The surgical and postoperative claims may contain inconsistent procedure codes or dates.

Denial 04

Post-op Care Conflict

The payer identifies postoperative care as being included or assigned differently within the claim.

Denial 05

Transfer Documentation

Documentation may not adequately support the transfer or expected transfer of care.

Denial 06

Global Period Conflict

The payer identifies another global surgery service or reporting conflict.

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

01

Wrong Modifier

The service may actually represent postoperative or preoperative management.

02

Global Package Conflict

Another claim may have been processed as the complete global surgical package.

03

Documentation Gap

The record may not support the transfer or expected transfer of care.

04

Payer Rule

The payer may apply specific requirements for global surgery and transfer-of-care reporting.
