What is Modifier GE?

Modifier GE identifies certain services furnished by a resident without the presence of a teaching physician under Medicare's primary care exception.

Normally, Medicare teaching physician rules require the teaching physician to meet specific participation requirements when billing for services involving residents. The primary care exception allows certain qualifying services furnished by residents in approved primary care settings to be billed without the teaching physician being physically present for the service.

The exception applies only when Medicare's specific requirements are satisfied. It is not a general exemption from teaching physician supervision requirements.

Modifier GE communicates that the reported service was furnished under this primary care exception and that the applicable requirements for resident involvement, teaching physician supervision, and the qualifying setting were met.

When to Use Modifier GE

Primary Care Exception Applies: The resident furnishes an eligible service under Medicare's primary care exception.

Teaching Physician Is Not Present: The qualifying service is furnished without the teaching physician's presence as permitted under the exception.

Qualifying Primary Care Setting: The service occurs in an eligible primary care center or setting that meets applicable Medicare requirements.

Eligible Resident Service: The reported service is one permitted under the primary care exception.

Teaching Physician Supervises the Resident: The teaching physician provides the required supervision even though they are not present for the qualifying service.

When NOT to Use Modifier GE

Primary Care Exception Does Not Apply: Do not report GE simply because a resident participated in a primary care service.

Service Requires Teaching Physician Presence: GE cannot be used to bypass teaching physician participation requirements for services outside the exception.

Setting Does Not Qualify: The modifier should not be reported when the service is furnished outside an eligible primary care setting.

Service Is Not Eligible: Not every service performed by a resident qualifies for the primary care exception.

Modifier GC Is Appropriate: When the service is performed in part by a resident under circumstances requiring the teaching physician's applicable participation, Modifier GC may be appropriate instead.

Billing Example

A Medicare beneficiary receives an eligible evaluation and management service at a qualifying primary care center.

A resident furnishes the service without the teaching physician being physically present during the encounter. The teaching physician provides the supervision required under Medicare's primary care exception and reviews the patient's care as required.

The applicable E/M code is reported with Modifier GE to indicate that the resident furnished the qualifying service without the teaching physician's presence under the primary care exception.

Documentation Requirements

Resident Participation: Document that the resident furnished the qualifying service.

Primary Care Exception: The record and practice circumstances should support that Medicare's primary care exception requirements were satisfied.

Teaching Physician Supervision: Documentation should support the teaching physician's required supervisory role.

Qualifying Setting: Maintain information demonstrating that the service was furnished in an eligible primary care setting.

Service Performed: The medical record should support the CPT or HCPCS code reported.

Medical Necessity: Documentation should establish why the underlying service was reasonable and necessary.

Billing and Claim Considerations

Modifier GE has a narrow Medicare purpose and should not be treated as a general resident-services modifier.

The primary care exception permits qualifying resident services to be billed without the teaching physician's presence only when the applicable Medicare requirements are satisfied.

The teaching physician still has supervisory responsibilities. The exception changes the presence requirements for qualifying services; it does not eliminate the teaching physician's responsibility for oversight of the resident and patient care.

Providers should also verify that the particular service is eligible under current primary care exception rules. A service performed in a primary care clinic does not automatically qualify merely because a resident furnished it.

When the primary care exception does not apply and the teaching physician satisfies the normal participation requirements for a resident service, Modifier GC may instead be appropriate.

Common Billing Mistakes

Using GE for Every Resident Service: GE is limited to services meeting Medicare's primary care exception requirements.

Assuming Primary Care Location Is Enough: A service does not qualify solely because it was performed in a primary care clinic.

Reporting an Ineligible Service: Only services permitted under the applicable primary care exception should be reported with GE.

Insufficient Teaching Physician Supervision: The teaching physician must still satisfy Medicare's supervisory requirements.

Confusing GE With GC: GE and GC represent different teaching physician and resident billing circumstances.

Missing Documentation: The medical record and supporting information should substantiate the service and applicable primary care exception requirements.

Common Denial Reasons

Primary Care Exception Requirements Are Not Met: The service does not satisfy Medicare's conditions for billing under the exception.

Service Is Not Eligible: The reported procedure or E/M service does not qualify for GE under applicable requirements.

Setting Does Not Qualify: The location where the service was furnished does not satisfy primary care exception requirements.

Teaching Physician Supervision Is Unsupported: Documentation does not demonstrate the required supervisory involvement.

Incorrect Modifier: The circumstances support GC or another billing method rather than GE.

Underlying Service Is Unsupported: Documentation does not substantiate the reported service or its medical necessity.

Modifier GE vs. Modifier GC

Modifier GE and Modifier GC both identify Medicare services involving residents, but the distinction between them is important.

Modifier GE identifies qualifying services furnished by a resident without the presence of a teaching physician under the primary care exception.

Modifier GC identifies a service performed in part by a resident under the direction of a teaching physician under applicable teaching physician requirements.

GE should therefore be reserved for services that specifically qualify for the primary care exception rather than used as an alternative whenever the teaching physician was absent.

Frequently Asked Questions

Does Modifier GE mean a teaching physician has no involvement in the service?
No. The primary care exception permits qualifying resident services without the teaching physician's presence, but the teaching physician must still satisfy applicable supervision requirements.

Can Modifier GE be used for every service performed by a resident in a primary care clinic?
No. The setting, service, resident, teaching physician supervision, and other applicable Medicare requirements must qualify for the primary care exception.
