Modifier 26
Professional Component
Learn what Modifier 26 means, when to use it, how professional component billing works, PC/TC indicators, global vs split billing, practical examples, common denials and AR follow-up strategies.
Modifier 26 at a Glance
The essential points every biller, coder and AR caller should know.
Professional Component
Modifier 26 identifies the professional component of an eligible PC/TC-split service.
Professional Work
It generally represents the physician’s professional work associated with the service.
Interpretation
For applicable diagnostic services, the professional component commonly includes interpretation and report.
Opposite of TC
Modifier TC identifies the technical component when the code supports separate PC/TC reporting.
What Is Modifier 26?
Understanding the professional component of a medical service.
Simple Definition
Modifier 26 is used to report the professional component of certain CPT or HCPCS services when the professional and technical components are separately reportable.
In Medicare billing, certain diagnostic and radiology services have a PC/TC split. When an eligible service is performed only from the professional side, Modifier 26 may identify that professional component.
CMS explains that for PC/TC indicator 1 services, the RVUs reported with Modifier 26 include physician work, practice expense and malpractice expense.
Easy Way to Remember
Think:
“26 = Professional side.”
If another entity performs the technical portion and the physician provides the professional service, the physician may report the eligible service with Modifier 26.
The exact applicability depends on the specific code and payer rules.
What Does the Professional Component Include?
The professional side is focused on physician professional work, rather than the technical performance of the service.
Physician Work
Professional work associated with interpreting or providing the applicable service.
Interpretation
Interpretation of an applicable diagnostic study when required by the service.
Report
Professional reporting associated with the interpretation when required.
Professional Expense
Applicable practice expense and malpractice expense included in the Medicare professional-component valuation.
Important
Modifier 26 does not mean “physician service” for every CPT code. It is specifically relevant to services where the professional and technical component concept applies. CMS states that physician-service codes with PC/TC indicator 0 cannot be billed with Modifier 26.
Modifier 26 vs Modifier TC
The most important distinction in professional and technical component billing.
Modifier 26
- Professional Component.
- Represents the professional side of an eligible PC/TC-split service.
- May include physician work and interpretation.
- Used when the professional component is reported separately.
Modifier TC
- Technical Component.
- Represents the technical side of an eligible PC/TC-split service.
- Generally includes applicable technical resources and practice expense.
- Used when the technical component is reported separately.
Simple Memory Trick
26 = Professional • TC = Technical • No Modifier = Global
The global concept applies only when the code and payer rules permit global billing.
Medicare PC/TC Indicators
Always verify the indicator before adding Modifier 26.
| Indicator | Meaning | Modifier 26? | Key Point |
|---|---|---|---|
| 0 | Physician service code | No | PC/TC concept does not apply. |
| 1 | Diagnostic test or radiology service | Yes | Generally has both professional and technical components. |
| 2 | Professional component only | No | The code already represents the professional component. |
| 3 | Technical component only | No | The code already represents the technical component. |
| 4 | Global test only | No | PC/TC modifiers do not apply. |
CMS Rule to Remember
CMS states that indicator 1 represents diagnostic tests or radiology services that generally have both professional and technical components, and Modifiers 26 and TC can be used with these codes. Indicator 2 represents professional-component-only codes, where Modifier 26 cannot be added.
Global vs Modifier 26 vs Modifier TC
Understand how the same service can be reported depending on who performs each component.
| Billing Method | Professional | Technical | Modifier |
|---|---|---|---|
| Global | Included | Included | None |
| Professional Only | Reported | Performed by another entity | 26 |
| Technical Only | Performed/reported separately | Reported | TC |
CMS Example
CMS’s PFS search example shows that when a provider performs both the professional and technical components of an applicable service, the service can be reported without a modifier. The same service can be separately reported with Modifier 26 when the provider performs only the professional component.
Modifier 26 Examples
Practical examples for medical billers, coders and AR callers.
A diagnostic imaging service is performed using equipment operated by one entity. A physician separately interprets the study and provides the professional report.
CPT-26If the CPT code is an eligible PC/TC-split service, the physician may report the professional component with Modifier 26.
A diagnostic facility performs the technical component while a physician performs the professional interpretation.
CPT-26The physician’s professional-component claim may use Modifier 26 when supported by the code and payer rules.
The same eligible billing entity performs both the technical and professional components.
CPTThe service may be reported globally without Modifier 26 when global billing is permitted.
The CPT code itself is designated as a professional-component- only code.
93010Do not automatically append Modifier 26. CMS identifies 93010 as an example of a professional-component-only code.
The code has a PC/TC indicator of 0 and represents a physician service.
26 NOT APPLICABLEModifier 26 should not be added because the PC/TC concept does not apply.
A claim with Modifier 26 is denied because the payer does not recognize the code as eligible for separate professional component billing.
REVIEW PC/TCThe AR caller should verify the exact CPT code, PC/TC indicator and payer policy before taking action.
Common Modifier 26 Denials
Common professional-component billing problems seen in AR.
Invalid Modifier
The payer indicates that Modifier 26 is not valid for the submitted procedure code.
PC/TC Mismatch
The code’s PC/TC indicator does not support separate professional component reporting.
Professional Component Included
The payer determines that the professional component is already included in the submitted service or payment arrangement.
Wrong Provider
The payer questions whether the billing provider performed the professional component.
Missing Interpretation
The payer requests documentation supporting the physician’s professional interpretation and report.
Global Billing Conflict
Another claim may have already reported the global service, creating a component or duplicate billing conflict.
Duplicate Professional Service
The payer identifies another professional-component claim for the same service and date.
Place of Service Issue
The submitted POS may not align with the professional service or payer processing rules.
Documentation Issue
The payer requires documentation supporting the professional component and interpretation.

Common Modifier 26 Billing Mistakes
Adding 26 to Every Diagnostic Code
Not every diagnostic code accepts Modifier 26. The specific PC/TC indicator must be checked.
Adding 26 to a PC-Only Code
If the code already represents the professional component, adding Modifier 26 may be incorrect.
Ignoring Global Billing
The team should determine whether the service is being reported globally or split between entities.
Confusing 26 With TC
Modifier 26 identifies the professional component, while TC identifies the technical component.
No Interpretation Documentation
The payer may require evidence supporting the professional interpretation and report.
Assuming All Payers Process 26 the Same
Commercial, Medicare Advantage and Medicaid plans may have payer-specific processing requirements.
ECG Example: 93005 vs 93010
A simple example that shows why the PC/TC indicator matters.
CPT 93005
Electrocardiogram; tracing only, without interpretation and report.
CMS identifies 93005 as an example of a technical-component-only code.
93005Because the code already represents the technical component, Modifier TC is not appended simply to identify it as technical.
CPT 93010
Electrocardiogram; interpretation and report.
CMS identifies 93010 as an example of a professional-component-only code.
93010Because the code already represents the professional component, Modifier 26 is not appended simply to identify it as professional.
Why This Example Matters
A common billing mistake is assuming that every professional diagnostic service requires “-26.” CMS’s PC/TC indicator determines whether the modifier is appropriate.
Modifier 26 and Medicare
What Medicare billers should verify before submitting the claim.
MPFSDB
Review the current Medicare Physician Fee Schedule Database for the applicable PC/TC indicator.
PC/TC Indicator

Modifier 26 FAQs
What is Modifier 26?
Modifier 26 identifies the professional component of an applicable CPT or HCPCS service when the professional and technical components are separately reportable.
What does Modifier 26 mean in medical billing?
Modifier 26 means that the provider is reporting the professional component of an eligible service rather than the complete global service.
What is the difference between Modifier 26 and TC?
Modifier 26 identifies the professional component, while TC identifies the technical component of an eligible PC/TC-split service.
Can Modifier 26 be used with every CPT code?
No. Modifier 26 is only appropriate when the specific code and payer rules support separate professional-component reporting.
What does Medicare PC/TC indicator 1 mean?
Indicator 1 identifies diagnostic tests or radiology services that generally have both professional and technical components. CMS states that Modifiers 26 and TC can be used with these codes when applicable.
What does Medicare PC/TC indicator 2 mean?
Indicator 2 identifies professional-component-only codes. CMS states that Modifiers 26 and TC cannot be used with these codes.
What is a global service?
For an eligible PC/TC-split service, a global service generally represents both the professional and technical components together. Whether global billing is allowed depends on the specific code and payer.
Does Modifier 26 mean physician interpretation?
For applicable diagnostic services, the professional component commonly includes the physician’s interpretation and report. The exact requirements depend on the code and payer.
Does Modifier 26 include equipment?
Modifier 26 represents the professional component rather than the technical equipment portion. Equipment and related technical resources generally belong to the technical component.
Can 26 and TC be billed on the same CPT code?
The professional and technical components may be separately reported by different entities when the code and payer rules permit. They should not simply be appended together by the same provider to create additional payment.
Can Modifier 26 be used with 93010?
CMS identifies 93010 as a professional-component-only code. Because the code already represents the professional component, Modifier 26 is not appended simply to identify it as professional.
Can Modifier 26 be used with 93005?
No. CMS identifies 93005 as a technical-component-only code. Modifier 26 cannot be used with a technical-component-only code.
Can an AR caller appeal a Modifier 26 denial?
Yes, when the professional component was correctly reported and the payer’s denial conflicts with applicable policy. Verify the CPT, PC/TC indicator, provider role, documentation and payer policy before appealing.
What should I check first for a Modifier 26 denial?
Start with the ERA/EOB denial reason, then verify the exact CPT/HCPCS code and current PC/TC indicator. Next verify the professional service, documentation, POS and payer policy.
Does Medicare pay Modifier 26 separately?
When the code is eligible for separate professional-component billing and Medicare requirements are satisfied, Medicare prices the professional component according to the applicable fee-schedule rules.
What is the easiest way to remember Modifier 26?
Remember: 26 = Professional and TC = Technical.
