Modifier 74- Discontinued Outpatient Procedure After Anesthesia

Modifier 74 is used when an outpatient hospital or ambulatory surgery center (ASC) procedure is discontinued after anesthesia has been administered or after the procedure has begun due to extenuating circumstances or patient safety concerns.

What Is Modifier 74?

Modifier 74 identifies a discontinued hospital outpatient or ambulatory surgical center procedure after anesthesia has been administered or after the procedure has begun.

CMS uses Modifier 74 when a procedure is terminated because of extenuating circumstances or circumstances threatening the patient's well-being after anesthesia administration or after the procedure itself has started.

Modifier 74 is primarily a facility reporting modifier. It is used by hospital outpatient departments and ASCs rather than on the physician's professional claim.

The timing of the discontinuation distinguishes Modifier 74 from Modifier 73, which generally applies when the procedure is discontinued before anesthesia administration.

When to Use Modifier 74

Anesthesia Has Been Administered: The procedure is discontinued after anesthesia begins.

Procedure Has Begun: Modifier 74 may apply when the procedure itself has started even when anesthesia is not involved.

Extenuating Circumstances: An unexpected circumstance prevents completion of the procedure.

Patient Well-Being: The patient's condition makes continuing the procedure unsafe or medically inappropriate.

Hospital Outpatient Facility: A qualifying HOPD procedure is discontinued after reaching the applicable procedural threshold.

Ambulatory Surgical Center: A qualifying ASC procedure is discontinued after anesthesia administration or procedure initiation.

When NOT to Use Modifier 74

Before Anesthesia Administration: Modifier 73 generally applies when a procedure involving planned anesthesia is discontinued after preparation and arrival in the procedure room but before anesthesia is administered.

Procedure Never Begins: Do not use Modifier 74 when neither anesthesia nor the procedure has begun.

Elective Cancellation: A procedure voluntarily cancelled or postponed before qualifying services are furnished should not be reported with Modifier 74.

Physician Professional Claim: Modifier 74 is intended for qualifying facility claims. Modifier 53 may be appropriate for the physician's discontinued procedure.

Completed Procedure: Do not use Modifier 74 when the intended procedure was completed despite complications or difficulty.

Billing Example

A patient is scheduled for an outpatient surgical procedure at an ASC.

The patient is prepared, taken to the procedure room, and anesthesia is administered.

Before the surgery can be completed, the patient develops an unexpected clinical condition that makes continuing the procedure unsafe.

The ASC reports the appropriate procedure code with Modifier 74 because anesthesia had already been administered before the procedure was discontinued.

The physician's professional reporting is evaluated separately under the applicable discontinued-procedure rules.

Documentation Requirements

Scheduled Procedure: Identify the procedure that was intended to be performed.

Anesthesia Administration: Document when anesthesia was administered when applicable.

Procedure Start: Establish whether and when the procedure itself began.

Reason for Discontinuation: Clearly document the clinical or extenuating circumstance requiring termination.

Patient Condition: Describe any change in the patient's condition that made continuing inappropriate or unsafe.

Services Performed: Document the procedural work and facility resources furnished before discontinuation.

Billing and Claim Considerations

Modifier 74 recognizes that significant facility resources may already have been consumed when a procedure is discontinued after anesthesia administration or procedure initiation.

For Medicare hospital outpatient services, a qualifying procedure reported with Modifier 74 generally receives the full OPPS payment amount. This differs from Modifier 73, for which qualifying discontinued procedures generally receive 50% of the full OPPS payment.

Full facility payment does not mean the procedure was completed. Modifier 74 communicates that the service was discontinued after the point at which substantial facility resources had already been used.

ASC payment rules should also be reviewed for the particular service because Medicare has specific payment methodology for discontinued ASC procedures, including special rules affecting certain device-intensive services.

Accurate documentation of when anesthesia was administered and when the procedure began is essential to selecting between Modifiers 73 and 74.

Common Billing Mistakes

Confusing 74 With 73: Modifier 73 generally applies before anesthesia, while Modifier 74 applies after anesthesia or procedure initiation.

Using 74 on Professional Claims: Modifier 74 is intended for qualifying hospital outpatient and ASC facility claims.

Assuming the Procedure Must Have Started: Modifier 74 can apply when anesthesia has already been administered even if the surgical procedure itself has not yet begun.

Reporting an Elective Cancellation: A routine cancellation does not automatically qualify as a discontinued procedure.

Failing to Document Timing: The record should establish when anesthesia was administered or the procedure began relative to discontinuation.

Confusing 74 With 53: Modifier 53 addresses qualifying discontinued physician/professional procedures rather than facility reporting.

Common Denial Reasons

Timing Not Supported: Documentation does not establish that anesthesia had been administered or the procedure had begun.

Incorrect Modifier: The circumstances support Modifier 52, 53, or 73 instead.

Elective Cancellation: Documentation indicates that the service was cancelled rather than discontinued because of qualifying circumstances.

Insufficient Documentation: The record does not explain why the procedure was terminated.

Facility Requirements Not Met: The claim does not satisfy applicable hospital outpatient or ASC reporting requirements.

Procedure Not Supported: Documentation does not support the underlying procedure reported on the claim.

Modifier 74 vs. Modifier 73

Modifier 74: Procedure discontinued after anesthesia administration or after the procedure has begun.

Modifier 73: Procedure discontinued after preparation and arrival in the procedure room but before anesthesia administration.

The key distinction is the timing of the discontinuation. This distinction also affects Medicare facility reimbursement.

Modifier 74 vs. Modifier 53

Modifier 74: Used by hospital outpatient departments and ASCs for qualifying discontinued facility procedures after anesthesia or procedure initiation.

Modifier 53: Used for qualifying discontinued physician or other professional services.

The same discontinued procedure may therefore involve different modifier reporting on the facility and professional claims.

Frequently Asked Questions

Does Modifier 74 mean the procedure was completed?
No. Modifier 74 specifically identifies a procedure that was discontinued. Medicare's full OPPS payment treatment reflects the facility resources consumed before discontinuation, not completion of the procedure.

Can Modifier 74 apply when anesthesia was administered but the actual surgery had not started?
Yes. When planned anesthesia has already been administered before a qualifying hospital outpatient or ASC procedure is discontinued, Modifier 74 may apply even if the operative portion has not yet begun.
