Modifier 25-Significant, Seperately Identifiable E/M Service

Identifies a significant, separately identifiable E/M service performed on the same day as another procedure or service.

What Is Modifier 25?

Modifier 25 is used when a physician or other qualified healthcare professional performs a significant, separately identifiable evaluation and management (E/M) service on the same day as another procedure or service.

The E/M service must go beyond the usual evaluation and management work that is already included in the procedure.

CMS confirms that Modifier 25 should be appended to the E/M code, not the procedure code, when the requirements for separate reporting are met.

A different diagnosis is not required. The E/M service may involve the same condition that prompted the procedure as long as the documentation demonstrates significant, separately identifiable work.

When to Use Modifier 25

Same-Day E/M and Procedure: A qualifying E/M service and another procedure or service are performed on the same date.

Separate E/M Work: The E/M service requires work beyond the usual pre- and post-procedure care.

Medical Necessity: The patient's condition supports a medically necessary E/M service in addition to the procedure.

Documentation Supports Both Services: The medical record clearly demonstrates the separately identifiable E/M work.

Appropriate E/M Code: Modifier 25 is appended to the qualifying E/M code rather than the procedure code.

When NOT to Use Modifier 25

Routine Procedure Work: Do not use Modifier 25 when the E/M work consists only of the usual evaluation associated with performing the procedure.

Decision for Major Surgery: Modifier 57, rather than Modifier 25, may apply when an E/M service results in the initial decision to perform major surgery.

Different Date of Service: Modifier 25 is intended for qualifying E/M and procedure services performed on the same day.

No Separate E/M Service: Do not append the modifier simply because an E/M code and procedure were documented on the same date.

To Bypass an Edit Automatically: Modifier 25 should only be reported when the clinical circumstances and documentation support its use.

Billing Example

A patient visits a physician for evaluation of a new skin problem.

During the encounter, the physician performs a medically necessary E/M service that goes beyond the work normally associated with a minor procedure performed during the same visit.

The physician documents the separate evaluation and the procedure.

The appropriate E/M code is reported with Modifier 25, while the procedure code is reported separately without Modifier 25.

Documentation Requirements

Separate E/M Service: Document the significant evaluation performed in addition to the procedure.

Medical Necessity: Explain why the patient's condition required the additional E/M service.

Procedure Documentation: Document the separately performed procedure.

Distinct E/M Work: The record should demonstrate work beyond the routine pre- and post-procedure services.

E/M Level: Documentation must support the level of E/M service reported.

Same-Day Services: The record should clearly establish the services performed during the encounter.

Billing and Claim Considerations

Modifier 25 does not automatically make an E/M service separately payable. The documentation must demonstrate that the E/M service was both significant and separately identifiable.

CMS emphasizes that many procedures already include routine pre-procedure and post-procedure evaluation. That inherent work cannot be separately reported as an E/M service merely by adding Modifier 25.

A separate diagnosis is not required for Modifier 25. The E/M service can relate to the same condition as the procedure as long as the separately reportable E/M requirements are satisfied.

CMS continues to identify improper same-day E/M billing as a compliance concern, making clear documentation particularly important when Modifier 25 is reported.

Common Billing Mistakes

Appending Modifier 25 to the Procedure: Modifier 25 should be appended to the qualifying E/M code.

Billing Routine Procedure Work: Normal pre- and post-procedure evaluation is generally included in the procedure.

Insufficient Documentation: The medical record does not demonstrate significant additional E/M work.

Assuming a Different Diagnosis Is Required: Modifier 25 does not require separate diagnoses when the services otherwise qualify.

Using Modifier 25 Instead of 57: Modifier 57 may be appropriate when the E/M service results in the decision for major surgery.

Automatic Modifier Use: Adding Modifier 25 to every same-day E/M and procedure claim can result in improper billing.

Common Denial Reasons

E/M Service Is Not Separately Identifiable: Documentation does not demonstrate work beyond that included in the procedure.

Medical Necessity Is Unsupported: The record does not establish the need for a separate E/M service.

Incorrect Modifier Placement: Modifier 25 is appended to the wrong service.

Documentation Is Insufficient: The record does not support the reported E/M level or separate work.

Service Is Bundled: The payer determines that the E/M work is included in the procedure.

Incorrect Modifier: Modifier 24, 57, or another modifier better represents the circumstances.

Modifier 25 vs. Modifier 24

Modifier 25: Significant, separately identifiable E/M service performed on the same day as another procedure or service.

Modifier 24: Unrelated E/M service performed during the postoperative period of a previous procedure.

Modifier 25 focuses on same-day services, while Modifier 24 focuses on an unrelated E/M service during a postoperative global period.

Modifier 25 vs. Modifier 57

Modifier 25: Used for a significant, separately identifiable E/M service performed on the same day as another procedure or service.

Modifier 57: Used when an E/M service results in the initial decision to perform major surgery.

Modifier 25 should not replace Modifier 57 when the encounter represents the decision for surgery.

Frequently Asked Questions

Does Modifier 25 require a different diagnosis for the E/M service and procedure?
No. CMS states that different diagnoses are not required. The documentation must instead demonstrate that the E/M service was significant and separately identifiable.

Can Modifier 25 be used with a minor procedure?
Yes. It may be appropriate when the patient requires a medically necessary E/M service beyond the usual work associated with the minor procedure.
