Modifier 76
Modifier 76 = Repeat procedure or service by the same physician or other qualified health care professional. Learn when Modifier 76 is appropriate, how it differs from Modifier 77, Modifier 91 and Modifier 59, how to identify repeat services, how to work denials, and how AR callers can document and appeal Modifier 76 claims.
Modifier 76 at a Glance
The essential points for billers, coders and AR callers.
Repeat Procedure
Identifies a procedure or service that was repeated after the original service.
Same Physician
The repeated procedure is performed by the same physician or other qualified health care professional.
Same Procedure
CMS states that the procedure must be the same procedure when Modifier 76 is used.
Separate Service
The repeated service must represent a genuine repeat service, not merely a duplicate claim submission.
What Is Modifier 76?
Understanding the modifier in simple medical billing language.
Simple Definition
Modifier 76 identifies a repeat procedure or service performed by the same physician or other qualified health care professional.
The second service is not simply a duplicate submission. It represents a procedure or service that was actually repeated after the original service.
CMS guidance states that the procedure must be the same procedure and that it should be reported again with the appropriate modifier.
Easy Way to Remember
Think:
“76 = Same provider repeated it.”
And:
76 = Same physician
77 = Another physician
Four Core Requirements for Modifier 76
Same Provider
The same physician or other qualified health care professional performs the repeated service.
Same Procedure
The service repeated must be the same procedure or service.
Actual Repeat
The service must actually have been performed again.
Documentation
The medical record should support why the procedure was repeated and establish the separate service.
Can Modifier 76 Be Used on the Same Day?
Yes.
CMS hospital guidance specifically addresses Modifier 76 for repeat procedures or services performed in a separate operative session on the same day. CMS also states that, for OPPS claims that generally span one calendar day, Modifiers 76 and 77 are used for procedures performed in a separate operative session or separate encounter on the same day.
For professional claims and payer-specific situations, always verify the applicable payer’s current billing policy.
Why Might a Procedure Be Repeated?
Modifier 76 describes the repeat service; the clinical reason should be supported by documentation.
Clinical Change
A patient’s condition changes and the same procedure is needed again.
Follow-Up Finding
A subsequent procedure is necessary because of a new or changing clinical finding.
Separate Encounter
The same procedure is performed again during a distinct encounter or operative session.
Repeat Imaging
The same imaging procedure may be repeated when medically necessary.
Repeat Interpretation
A physician may interpret repeated imaging or diagnostic services when the applicable requirements are met.
New Clinical Need
A repeat service may be necessary because additional clinical information is required.
Modifier 76 vs Modifier 77
The provider who performs the repeat procedure is the key difference.
| Feature | Modifier 76 | Modifier 77 |
|---|---|---|
| Basic Meaning | Repeat procedure/service by same physician or QHP | Repeat procedure/service by another physician or QHP |
| Performing Provider | Same physician/QHP | Different physician/QHP |
| Procedure | Same procedure | Same procedure |
| Example | Dr. A performs a chest X-ray interpretation and later repeats the interpretation. | Dr. A performs the first interpretation and Dr. B performs the repeated interpretation. |
| Memory Tip | 76 = Same | 77 = Another |
Modifier 76 vs Modifier 91
Do not use Modifier 76 automatically for every repeated test.
| Feature | Modifier 76 | Modifier 91 |
|---|---|---|
| Basic Purpose | Repeat procedure/service by same physician or QHP | Repeat clinical diagnostic laboratory test |
| Common Area | Procedures, imaging, interpretations and other applicable services | Clinical laboratory testing |
| Same Day | May apply when a qualifying service is repeated | May apply when a lab test is repeated to obtain additional medically necessary results |
| Testing Due to Equipment/Specimen Problem | Not automatically 76 | CMS guidance says Modifier 91 should not be used when testing is repeated because of testing problems with equipment or specimens. |
| Key Question | Was the same procedure/service repeated by the same provider? | Was the clinical diagnostic laboratory test repeated to obtain multiple medically necessary results? |
Modifier 76 vs Modifier 59
| Modifier | Main Concept | Key Question |
|---|---|---|
| 76 | Repeat procedure/service by same physician/QHP | Was the same service actually repeated? |
| 59 | Distinct procedural service | Was the service distinct from another service because of a qualifying circumstance? |
| Clinical Concept | Repetition | Distinctness |
| Example | Same procedure performed again. | Two procedures that would otherwise be considered bundled but are separately reportable because of a qualifying circumstance. |
Important NCCI Point
CMS’s 2026 NCCI Policy Manual states that Modifiers 76 and 77 are not NCCI PTP-associated modifiers. Therefore, appending Modifier 76 does not bypass an NCCI Procedure-to- Procedure edit.
This is an important distinction for denial management: do not append Modifier 76 simply to overcome an NCCI edit.
Duplicate Claim vs Repeat Procedure
This is one of the most important concepts for AR callers.
Duplicate Claim
A duplicate claim means the same service was accidentally submitted more than once.
- Same patient
- Same date of service
- Same procedure
- Same provider
- No evidence of a second service
Do not use Modifier 76 just to make a duplicate claim payable.
Genuine Repeat Procedure
A genuine repeat procedure means the service actually happened again and the documentation supports the second service.
- Original procedure occurred
- Second procedure actually occurred
- Same physician/QHP performed the repeat
- Medical record supports the repeat
- Modifier 76 requirements are satisfied
Modifier 76 Examples
Practical examples for medical billing and AR.
A patient receives two chest X-rays on the same day. The same physician interprets the first study and later performs a separate interpretation of the second study.
CPT XXXXX-76When the applicable requirements are met, Modifier 76 can identify the repeat service by the same physician.
An EKG is interpreted in the morning and another EKG is performed later because the patient’s clinical condition changes. The same physician interprets the second EKG.
CPT XXXXX-76CMS has specific guidance recognizing Modifier 76 for repeated same-day EKG or X-ray interpretations by the same physician.
The first physician performs the original procedure. A second physician performs the same procedure later.
Evaluate Modifier 77Modifier 76 would not describe the provider relationship when a different physician performed the repeat procedure.
The billing department submits the same procedure twice by mistake. There is no second procedure in the medical record.
NOT Modifier 76This is a duplicate billing issue, not a repeat procedure.
A clinical diagnostic laboratory test is repeated to obtain medically necessary additional results.
Evaluate Modifier 91The appropriate modifier depends on the service and circumstances. Do not automatically use 76 for a repeated clinical diagnostic laboratory test.
Two different procedures are performed during the same encounter and are separately reportable because they meet a qualifying distinct-service circumstance.
Evaluate Modifier 59This is a distinct-service concept, not a repeat-procedure concept.
Common Modifier 76 Denials
Common denial scenarios for AR and denial-management teams.
Duplicate Service
The payer believes the second claim represents a duplicate submission rather than a genuine repeat service.
Modifier 76 Not Supported
The payer does not find sufficient documentation supporting the repeat procedure.
Wrong Provider Modifier
The payer determines that another physician performed the repeat service, requiring evaluation of Modifier 77 instead.
Repeat Not Medically Necessary
The payer does not find sufficient clinical support for repeating the procedure.
Incorrect Modifier 91
A repeated laboratory service may require evaluation under Modifier 91 rather than Modifier 76.
Incorrect Modifier 59
A distinct-service situation may have been incorrectly billed as a repeat procedure.
Same Procedure Not Established
The payer cannot determine that the second service was the same procedure as the original service.
Documentation Missing
The operative report, procedure note or diagnostic report does not establish that a second service occurred.
NCCI Edit
Modifier 76 does not bypass an NCCI PTP edit simply because it was appended to the claim.
How an AR Caller Should Work a Modifier 76 Denial
Step-by-step denial management workflow.
Review the ERA / EOB
Identify the denial reason, CARC, RARC, claim line and adjustment amount.
Confirm the Procedure Code
Identify the exact CPT/HCPCS code billed with Modifier 76.
Compare Both Claim Lines
Compare the first and repeat service by date, procedure, provider, units and modifiers.
Confirm Same Provider
Verify that the same physician or qualified health care professional performed the repeated service.
Confirm Same Procedure
Verify that the second service was the same procedure as the original service.
Review Medical Record
Verify that the second procedure actually occurred and that documentation supports the repeat.
Rule Out Duplicate Billing
Make sure the second claim line is not simply a duplicate submission.
Compare 76 vs 77
If a different physician performed the repeat service, evaluate Modifier 77 instead.
Check 91 / 59
If the service is a clinical laboratory test or a distinct service rather than a repeat procedure, evaluate the appropriate alternative.
Appeal or Correct
If Modifier 76 is supported, submit reconsideration with documentation. If the modifier is incorrect, follow the payer’s corrected-claim process.
Document Follow-Up
Record payer representative, reference number, action taken, documents submitted and next follow-up date.

Modifier 76 in Radiology
Same Physician
CMS provides examples involving repeated X-ray or EKG interpretations by the same physician on the same day.
The first service is reported normally, while the repeated service may be reported with Modifier 76 when the applicable requirements are met.
First: CPT 710XX Repeat: CPT 710XX-76Different Physician
If another physician performs the repeat interpretation, Modifier 77 may be appropriate instead.
First: CPT 710XX Repeat: CPT 710XX-77Modifier 76 and Medicare
Medicare Review Checklist
- Verify the CPT/HCPCS code.
- Verify the original and repeated services.
- Verify the performing physician/QHP.
- Verify the date and timing of the services.
- Verify documentation supporting the repeat.
- Review applicable Medicare coverage requirements.
- Review current NCCI edits and indicators.
- Review the applicable MAC billing policy.
Important Medicare Point
Medicare does not treat Modifier 76 as a universal override modifier.
CMS’s 2026 NCCI Policy Manual specifically states that Modifiers 76 and 77 are not NCCI PTP-associated modifiers.
Therefore, simply adding 76 to a claim line does not establish that an NCCI edit should be bypassed.

Modifier 76 FAQs
What is Modifier 76?
Modifier 76 indicates a repeat procedure or service performed by the same physician or other qualified health care professional.
What does Modifier 76 mean in medical billing?
It tells the payer that the same procedure or service was performed again by the same physician or qualified health care professional.
Can Modifier 76 be used on the same day?
Yes. CMS hospital guidance specifically addresses repeat procedures performed in a separate operative session or separate encounter on the same day. Payer-specific rules should still be verified.
What is the difference between Modifier 76 and 77?
Modifier 76 is for a repeat procedure by the same physician or QHP. Modifier 77 is for a repeat procedure by another physician or QHP.
Is Modifier 76 the same as Modifier 91?
No. Modifier 91 is specifically used for qualifying repeated clinical diagnostic laboratory tests. Modifier 76 is the repeat procedure/service modifier for the same physician or QHP.
Is Modifier 76 the same as Modifier 59?
No. Modifier 76 identifies a repeat procedure. Modifier 59 identifies a distinct procedural service when the applicable distinct-service requirements are met.
Can Modifier 76 be used to fix a duplicate claim?
No. If the second claim was submitted accidentally and there was no second procedure, it is a duplicate billing issue, not a genuine repeat procedure.
Does Modifier 76 mean the procedure was medically necessary?
No. The modifier describes the repeat-service circumstance. The underlying service must still satisfy applicable medical necessity and coverage requirements.
Does Modifier 76 bypass NCCI edits?
No. CMS’s 2026 NCCI Policy Manual states that Modifiers 76 and 77 are not NCCI PTP-associated modifiers and therefore do not bypass an NCCI PTP edit.
What documentation supports Modifier 76?
The record should support the original service, the repeat service, the same performing physician/QHP, the timing and, when relevant, the clinical reason for repeating the service.
Can Modifier 76 be used for radiology?
Yes. CMS guidance specifically includes Modifier 76 among modifiers applicable to radiology services and provides examples involving repeated X-ray and EKG interpretations.
Who can perform the repeat procedure for Modifier 76?
The same physician or other qualified health care professional must perform the repeat service for Modifier 76.
What if another physician performs the repeat?
Evaluate Modifier 77 because Modifier 77 is the repeat procedure modifier for another physician or qualified health care professional.
Can Modifier 76 be used multiple times?
When a procedure is genuinely repeated multiple times and the applicable coding and payer requirements are met, the repeat service(s) may require appropriate reporting. Verify the specific payer and CPT instructions.
What should an AR caller check first?
Start with the ERA/EOB, then compare the original and repeat claim lines, verify the provider, procedure, documentation and payer policy.
Is Modifier 76 a payment guarantee?
No. Modifier 76 only describes the repeat-service circumstance. Coverage, medical necessity, coding edits, documentation and payer policy can still affect payment.
