Modifier 57
Complete guide to Modifier 57 — Decision for Surgery. Learn when Modifier 57 should be appended to an Evaluation and Management service, how it differs from Modifier 25, and how AR callers should work Modifier 57 denials.
Modifier 57 at a Glance
Understand the core rule before moving into examples and denial workflows.
Modifier
Decision for Surgery.
E/M Service
Appended to the appropriate E/M service.
Decision
The encounter resulted in the initial decision to perform surgery.
Major Surgery
Particularly important when a major surgical procedure has a 90-day global period.
Documentation
The record must support the E/M service and the decision for surgery.
What Is Modifier 57?
Modifier 57 identifies an E/M service that resulted in the initial decision to perform surgery.
Simple Definition
Modifier 57 — Decision for Surgery is appended to an appropriate E/M service when that encounter resulted in the physician or other qualified health care professional making the initial decision to perform surgery.
The key question is not simply whether surgery happened on the same date.
The key question is:
Did this E/M service result in the initial decision to perform the surgery?

Why Is Modifier 57 Important?
Modifier 57 helps distinguish an E/M service that resulted in a decision for surgery from other preoperative services included in surgical payment.
Identifies the Decision
It communicates that the E/M encounter resulted in the initial decision to perform surgery.
Supports Separate E/M Reporting
When applicable Medicare global-surgery rules would otherwise include the service, Modifier 57 identifies the decision-for-surgery E/M.
Prevents Modifier Confusion
Modifier 57 should not simply be substituted for Modifier 25 or other modifiers.
Helps AR Follow-Up
Understanding the modifier makes it easier to determine whether a denial requires correction, reconsideration or appeal.
The Core Modifier 57 Rule
Ask One Question
Did the E/M service result in the initial decision to perform surgery?
If yes, Modifier 57 may be appropriate when all other applicable coding and payer requirements are satisfied.
CMS describes Modifier 57 as the modifier for an E/M service that resulted in the initial decision to perform surgery. :contentReference[oaicite:1]{index=1}
When Should Modifier 57 Be Used?
Use Modifier 57 only when the documentation supports the decision-for-surgery scenario.
Modifier 57: Major vs Minor Surgery
This distinction is critical when working Medicare claims.
| Major Surgery | Minor Surgery |
|---|---|
| Generally associated with a 90-day global period. | Generally associated with a 000- or 010-day global period. |
| An E/M service resulting in the decision for surgery may be reported with Modifier 57 when applicable. | The decision to perform the minor procedure is generally included in the payment for the minor procedure. |
| Modifier 57 is the relevant decision-for-surgery modifier when requirements are met. | A significant, separately identifiable unrelated E/M may be reported with Modifier 25 when requirements are met. |
Important Medicare Rule
CMS states that when a procedure has a 000- or 010-day global period, the decision to perform the minor surgical procedure is generally included in the payment for that procedure.
CMS further explains that a significant and separately identifiable E/M service unrelated to the decision for the minor procedure may be reported with Modifier 25. :contentReference[oaicite:2]{index=2}
Modifier 57 vs Modifier 25
One of the most important distinctions for coders and AR callers.
| Modifier 57 | Modifier 25 |
|---|---|
| Decision for surgery. | Significant, separately identifiable E/M. |
| The E/M service resulted in the initial decision to perform surgery. | The E/M service is significant and separately identifiable from the procedure/service. |
| Commonly relevant to major surgery with a 90-day global period. | Commonly used with procedures/services performed on the same day. |
| Identifies the decision for surgery. | Identifies a separately identifiable E/M service. |
| Not simply a replacement for Modifier 25. | Not used for an E/M service that resulted in the decision to perform surgery. |
Easy Memory Trick
57 = Surgery Decision
25 = Separate E/M
AMA specifically notes that Modifier 25 is not used when the E/M service resulted in the decision to perform surgery; in that circumstance Modifier 57 should be used. :contentReference[oaicite:3]{index=3}
Modifier 57 vs Modifier 24
| Modifier 57 | Modifier 24 |
|---|---|
| Decision for surgery. | Unrelated E/M during a postoperative period. |
| Used for the E/M service leading to the initial surgical decision. | Used when an unrelated E/M service is performed during a postoperative global period. |
| Focuses on the decision to operate. | Focuses on unrelated postoperative care. |
Modifier 57 vs Modifier 58
| Modifier 57 | Modifier 58 |
|---|---|
| Applies to an E/M service involving the initial decision for surgery. | Applies to a subsequent procedure during a postoperative period. |
| Decision for surgery. | Staged, planned or more extensive related procedure. |
| E/M modifier. | Procedure modifier. |
When Should Modifier 57 NOT Be Used?
Routine Preoperative Exam
Do not use Modifier 57 merely because an E/M service was performed before surgery.
Surgery Was Already Decided
If the decision to perform surgery was already made during a previous encounter, a later routine preoperative visit does not automatically qualify for Modifier 57.
Minor Procedure Decision
For a minor procedure, the decision to perform the procedure is generally included in the procedure payment under Medicare global-surgery rules.
Unrelated Postoperative Visit
That is a different scenario and may require Modifier 24 when applicable.
Separately Identifiable E/M
If the issue is a significant, separately identifiable E/M service on the same day as a minor procedure, evaluate Modifier 25 instead.
No Documentation
Do not append a modifier simply to obtain separate payment when the medical record does not support the E/M service and surgical decision.
Modifier 57 Examples
Educational scenarios to understand the concept.
A patient presents with a condition requiring significant evaluation. The provider discusses treatment options and determines that major surgery is necessary.
The E/M encounter results in the initial decision to perform surgery.
Result:
Modifier 57 may be appropriate on the E/M service when the applicable requirements are met.
The provider previously decided that the patient will undergo surgery.
The patient returns for routine preoperative preparation.
Result:
The later preoperative service does not automatically qualify for Modifier 57 merely because surgery will occur.
A patient presents for evaluation and the provider decides to perform a minor procedure with a 000-day global period.
Result:
Under Medicare global-surgery rules, the decision for the minor procedure is generally included in the procedure payment. Modifier 57 is not used simply to separately report that decision.
The patient presents with a separate problem. The provider performs a significant, separately identifiable E/M service and also performs a minor procedure.
Result:
Evaluate whether Modifier 25 is appropriate, rather than Modifier 57.
Common Clinical Scenarios
Orthopedic Surgery
The provider evaluates a significant orthopedic condition, reviews treatment options and makes the initial decision for major surgery.
General Surgery
The physician evaluates the patient’s condition, discusses surgical treatment and makes the decision to proceed.
Neurosurgery
A detailed E/M encounter results in a decision to proceed with a major surgical intervention.
Ophthalmology
The provider evaluates the condition and determines that a surgical intervention is required.
Cardiovascular Surgery
The E/M service may result in a decision for significant surgical treatment.
ENT Surgery
The physician evaluates the patient and makes the initial surgical decision when clinically indicated.
Documentation Requirements
The medical record should support both the E/M service and the decision-making process.
Look for These Elements
- Patient’s presenting problem
- Relevant history
- Examination when applicable
- Medical decision-making
- Review of diagnostic information
- Assessment of the condition
- Surgical treatment discussion
- Initial decision to perform surgery
Strong Documentation
Strong documentation should make it clear that the provider evaluated the patient’s condition and that the encounter resulted in the decision to perform the surgery.
Good documentation concept:
“After evaluation of the patient’s condition, available treatment options were reviewed. Surgical treatment was discussed and the decision was made to proceed with surgery.”
The exact clinical documentation must reflect what actually occurred; documentation should never be created merely to support a modifier.
How to Work a Modifier 57 Denial
Practical AR workflow for denied claims.
Review the Claim
Verify the E/M code, Modifier 57, surgical procedure, date of service and payer.
Identify the Global Period
Determine whether the surgical procedure is associated with a 90-day, 010-day or 000-day global period.
Read the ERA / EOB
Identify the exact denial reason and obtain CARC/RARC information when available.
Confirm the Surgical Decision
Determine whether the E/M encounter actually resulted in the initial decision to perform surgery.
Review Documentation
Verify that the medical record supports the E/M service and decision-making.
Check Modifier Selection
Determine whether Modifier 57 or Modifier 25 is appropriate based on the actual circumstances.
Correct or Appeal
If the modifier was incorrect, follow the payer’s correction process. If supported, submit reconsideration or appeal.
Document the Follow-Up
Record payer representative, reference number, action taken, submission date and next follow-up.
Common Modifier 57 Denials
Common issues encountered by AR callers and medical billing teams.
E/M Included in Global Surgery
The payer processed the E/M service as included in the surgical global payment.
Modifier Not Supported
The payer determined that documentation did not support Modifier 57.
Wrong Modifier
The service may have been reported with Modifier 25 or another modifier when Modifier 57 was appropriate, or vice versa.
Minor Procedure
Modifier 57 was submitted with a minor procedure where the decision to perform the procedure is generally included in payment.
Routine Preoperative Visit
The payer determined that the E/M was routine preoperative care rather than the initial decision-for-surgery encounter.
Documentation Insufficient
The medical record does not clearly establish the decision-making and surgical plan.
Modifier 57 Denial Root-Cause Analysis
Global Period
The E/M may be subject to the global surgery payment rules.
Wrong Modifier
Modifier 25 and Modifier 57 may have been confused.
No Initial Decision
The surgical decision occurred during an earlier encounter.
Documentation
The record does not adequately support the decision-making.
AR Caller Script for Modifier 57

Common Modifier 57 Mistakes
01. Using 57 on Every Preoperative Visit
A preoperative visit is not automatically a decision-for-surgery E/M.
02. Confusing 57 With 25
Modifier 25 and Modifier 57 represent different circumstances.
03. Using 57 for Minor Surgery
Medicare’s global-surgery rules generally include the decision to perform a minor procedure.
04. Ignoring the Global Period
Always determine whether the surgical procedure has a 90-day, 010-day or 000-day global period.
05. Assuming the Modifier Guarantees Payment
The modifier must be supported by the documentation and applicable payer rules.
06. Not Checking the Medical Record
AR should not appeal solely from the claim line. The record should support the decision-making.
