Modifier 55- Postoperative Management Only

Identifies postoperative management provided by a physician or qualified healthcare professional who did not perform the surgical procedure.

What Is Modifier 55?

Modifier 55 identifies postoperative management only when postoperative care included in a surgical global package is formally transferred from the operating surgeon to another physician or qualified healthcare professional.

Under Medicare's global surgery rules, payment for many surgical procedures includes the surgery itself and related postoperative care. When responsibility for these services is divided between practitioners, modifiers are used to identify the portion of the global package each practitioner provides.

The surgeon transferring postoperative care generally reports the surgical procedure with Modifier 54, while the practitioner accepting postoperative management reports the same procedure code with Modifier 55.

Modifier 55 does not identify an individual postoperative office visit. It represents the practitioner's responsibility for the applicable postoperative management portion of the global surgical package.

When to Use Modifier 55

Postoperative Care Is Transferred: Another practitioner formally assumes postoperative management from the operating surgeon.

Receiving Practitioner Provides Follow-Up Care: The practitioner reporting Modifier 55 manages qualifying postoperative care during the global period.

Procedure Has an Applicable Global Period: The surgical procedure includes postoperative management that may be divided between practitioners.

Transfer Is Documented: The medical record establishes the transfer of care and when postoperative management began.

Same Surgical Procedure Code Is Reported: The receiving practitioner generally reports the surgical procedure code with Modifier 55 rather than separately reporting routine postoperative E/M visits included in the global package.

When NOT to Use Modifier 55

Practitioner Performed the Surgery: The operating surgeon should not use Modifier 55 to represent the surgical portion of the service.

No Transfer of Care Occurred: Seeing a patient during another physician's global period does not automatically establish postoperative management.

Care Is Unrelated to the Surgery: Modifier 24 may be appropriate for a qualifying unrelated E/M service during a postoperative period instead.

Visit Is Outside the Global Package: Services outside the applicable global period should be reported according to their normal coding requirements.

Procedure Has No Applicable Postoperative Management: Modifier 55 is not appropriate when there is no postoperative component available for separate reporting.

Billing Example

A surgeon performs a qualifying surgical procedure but will not provide the patient's postoperative management.

The surgeon formally transfers postoperative care to another physician.

The surgeon reports the procedure with Modifier 54 to identify surgical care only.

The physician accepting responsibility for postoperative management reports the same procedure code with Modifier 55 and documents the date postoperative care began.

This allows the surgical and postoperative portions of the global package to be allocated between the practitioners according to applicable Medicare rules.

Documentation Requirements

Transfer of Care: Document that postoperative management was formally transferred from the operating surgeon.

Transfer Date: Record the date the receiving practitioner assumed responsibility for postoperative care.

Operating Surgeon: Identify the practitioner who performed the original surgical procedure.

Postoperative Management: Document the postoperative services and management provided during the applicable period.

Surgical Procedure: Maintain information identifying the procedure associated with the transferred postoperative care.

Global Period: Verify that the procedure has an applicable postoperative global period.

Billing and Claim Considerations

Medicare requires specific information when postoperative management is divided between practitioners.

The physician providing postoperative management reports the same surgical procedure code with Modifier 55 and indicates the date care was assumed. CMS uses the transfer date and the number of postoperative days managed when determining the appropriate payment.

When a surgeon transfers the entire postoperative portion of the global package, the surgeon generally reports Modifier 54 and the receiving practitioner reports Modifier 55.

When postoperative management is transferred between more than one practitioner during the global period, each practitioner may report Modifier 55 for the portion of postoperative care actually provided, subject to Medicare's transfer-of-care requirements.

Modifier 55 should therefore be viewed as a global surgery payment modifier, not simply as a modifier for a postoperative office visit.

Common Billing Mistakes

Billing Individual Routine E/M Visits: Routine postoperative visits included in the transferred global package generally should not also be separately billed as ordinary E/M services.

Using 55 Without a Formal Transfer: A referral, consultation, or isolated postoperative encounter does not automatically qualify as transferred postoperative management.

Confusing 55 With 54: Modifier 54 identifies surgical care only; Modifier 55 identifies postoperative management only.

Confusing 55 With 24: Modifier 24 addresses an unrelated E/M service during the postoperative period rather than routine postoperative management.

Missing the Transfer Date: Medicare needs accurate information about when postoperative management began.

Reporting the Wrong Procedure Code: The practitioner accepting postoperative management generally reports the same surgical procedure code associated with the global package.

Common Denial Reasons

Transfer of Care Not Supported: Documentation does not demonstrate that postoperative management was formally transferred.

Incorrect Modifier: The circumstances support Modifier 24, 54, 56, or another reporting method instead.

Transfer Information Missing: Required information regarding when postoperative management began is absent or inconsistent.

Procedure Does Not Support Modifier 55: The underlying procedure does not have an applicable postoperative global component.

Conflicting Claims: Information reported by the surgeon and postoperative provider does not consistently reflect the transfer of care.

Duplicate Postoperative Billing: Routine global postoperative care is also reported separately using E/M codes.

Modifier 55 vs. Modifier 54

Modifier 55: Postoperative management only.

Modifier 54: Surgical care only.

These modifiers commonly work together when the operating surgeon performs the surgery but formally transfers postoperative management to another practitioner.

Modifier 55 vs. Modifier 24

Modifier 55: Identifies routine postoperative management transferred from the operating surgeon.

Modifier 24: Identifies a qualifying E/M service that is unrelated to the original surgery during the postoperative period.

The key distinction is whether the care represents routine management of the surgery or an unrelated E/M service.

Frequently Asked Questions

Does Modifier 55 go on each postoperative E/M visit?
No. The practitioner generally reports the surgical procedure code with Modifier 55 to identify the transferred postoperative management portion of the global package rather than attaching 55 to each routine postoperative E/M visit.

Can more than one physician report Modifier 55 during the same global period?
Yes, when postoperative management is formally transferred between practitioners. Each practitioner must report and document the portion of postoperative care for which they were responsible according to applicable Medicare requirements.
