A modifier 25 audit can affect many medical specialties, not just ophthalmology. Any practice that bills an office visit on the same day as a procedure should pay close attention.
Modifier 25 is used when a provider performs a significant, separately identifiable evaluation and management service on the same day as a procedure or other service. However, it should not be added automatically just because an office visit and procedure happened on the same date.
For medical practices, the main question is simple: does the chart clearly show that the E/M service was separate from the usual procedure work?
If the answer is not clear, the claim may be vulnerable during an audit.
Ameriton Workforce Solutions helps medical practices stay organized with remote administrative support, billing support, prior authorization support, and insurance verification support.

What Is Modifier 25?
Modifier 25 is added to an E/M code when the provider performs a significant and separately identifiable E/M service on the same day as a procedure.
In simple terms, the visit must go beyond the normal work already included in the procedure.
For example, a provider may evaluate a new problem, review new symptoms, change the treatment plan, address a separate condition, or make a decision that requires additional medical decision making.
However, if the provider only confirms that a planned procedure can be done, that may not support a separate E/M visit.
Why Modifier 25 Is Getting More Attention
Modifier 25 is getting more attention because payers and auditors want to know whether same-day E/M services are truly separate from the procedure.
This issue can affect many specialties, including:
- Ophthalmology
- Retina
- Dermatology
- Orthopedics
- Pain management
- ENT
- Urology
- Gastroenterology
- Rheumatology
- Cardiology
- Podiatry
- General surgery
- Allergy and immunology
- Primary care practices that perform procedures
Because many specialties perform same-day procedures, a modifier 25 audit is not limited to one type of practice.
The Main Problem: The Note Does Not Tell the Full Story
Many modifier 25 problems happen because the documentation is too vague.
The provider may have done a separate evaluation, but the note may not clearly show it. As a result, the auditor may think the E/M service was part of the procedure.
For example, a weak note may say:
“Patient seen today. Procedure performed. Follow up as needed.”
That does not explain why a separate office visit was needed.
A stronger note explains the patient’s problem, the provider’s assessment, the medical decision making, and why the procedure was not the only service performed.
Problem 1: Modifier 25 Is Used Automatically
One major risk is adding modifier 25 out of habit.
Some offices add it any time an E/M visit and procedure are billed together. However, that can create audit risk.
Modifier 25 should only be used when the medical record supports a separate E/M service.
Before billing, the team should ask:
- Was a separate problem evaluated?
- Was there new or worsening information?
- Did the provider change the treatment plan?
- Was additional medical decision making documented?
- Was the E/M work above and beyond the usual procedure work?
- Would the visit still make sense without the procedure?
If the answer is no, modifier 25 may not be appropriate.
Problem 2: The E/M Service Is Not Clearly Separate
A second issue is unclear separation between the visit and the procedure.
The chart should make it easy to see what work supported the E/M code and what work supported the procedure.
For example, the procedure note should describe the procedure. Meanwhile, the E/M note should support the history, exam, assessment, and medical decision making for the separate visit.
When everything is blended together, the record becomes harder to defend.
Because of this, practices should make sure the documentation clearly shows why the visit was significant and separately identifiable.
Problem 3: The Diagnosis Does Not Explain the Story
A different diagnosis is not always required for modifier 25. However, the diagnosis coding should still make sense.
If the E/M service was for a separate issue, the diagnosis codes should help show that. If the same diagnosis applies to both the visit and the procedure, the note should still explain why the E/M work was separate.
In other words, diagnosis codes help, but they do not replace documentation.
The chart still needs to support the service.
Why Same-Day Procedures Create Audit Risk
Same-day procedures are common in medical offices.
A patient may come in for a visit and also receive an injection, biopsy, scope, treatment, removal, test, or minor procedure. In many cases, that may be appropriate.
However, payers may question whether the office visit was truly separate.
This is especially important for procedures with a 0-day or 10-day global period because some pre-service and post-service work is already included in the procedure payment.
Therefore, the practice must show that the E/M service went beyond the usual procedure work.
Examples of When Modifier 25 May Be Appropriate
Modifier 25 may be appropriate when the provider performs a separate, significant E/M service on the same day as a procedure.
Possible examples include:
- A new patient needs a full evaluation before treatment is decided
- An established patient presents with a new problem
- The patient has worsening symptoms that require assessment
- The provider changes the treatment plan
- A separate diagnosis is evaluated
- New test results change the plan of care
- The provider evaluates a different body area or condition
- The visit includes additional medical decision making beyond the procedure
Still, the documentation must support the separate work.
Examples of When Modifier 25 May Not Be Appropriate
Modifier 25 may not be appropriate when the visit only supports the procedure.
For example, it may be risky when:
- The patient arrives for a planned procedure only
- The provider only confirms the patient can proceed
- The note only documents routine pre-procedure work
- The E/M service is not separately identifiable
- The procedure decision was already made at a prior visit
- The documentation does not show additional medical decision making
- The chart does not explain why the office visit was needed
In these cases, the E/M service may be viewed as part of the procedure.
What Medical Practices Should Fix Now
Medical practices should not wait for a modifier 25 audit to review their process.
Instead, they should fix common documentation and billing problems now.
Start by reviewing same-day E/M and procedure claims. Then, check whether the notes clearly support the separate visit.
Practices should review:
- E/M notes billed with modifier 25
- Same-day minor procedures
- Same-day injections
- Same-day biopsies
- Same-day scopes
- Same-day treatments
- High-volume provider patterns
- High-use CPT code combinations
- Denials related to modifier 25
- Payer requests for records
- Provider documentation habits
This review can help the practice find weak areas before an auditor does.
Create a Modifier 25 Checklist
A simple checklist can help staff and providers stay consistent.
Before billing modifier 25, ask:
- Was an E/M service performed?
- Was the E/M service significant?
- Was it separately identifiable?
- Was it above and beyond the usual procedure work?
- Does the note support medical necessity?
- Does the assessment show what was evaluated?
- Does the plan show what was decided?
- Does the procedure note stand on its own?
- Does the diagnosis coding make sense?
- Would an auditor understand why both services were billed?
If the answer is unclear, the chart should be reviewed before the claim is submitted.
Train Providers on Clear Documentation
Provider documentation is one of the most important parts of modifier 25 compliance.
The provider should clearly document why the patient needed a separate evaluation. In addition, the note should show the medical decision making that supports the E/M level.
Helpful documentation may include:
- New symptoms
- Worsening condition
- Separate complaint
- Medication change
- Treatment plan change
- New diagnosis
- Additional testing reviewed
- Risk discussion
- Provider decision making
- Reason the procedure was performed that day
- Follow-up plan
Clear documentation protects the provider, the biller, and the practice.
Train Billing Staff on When to Pause
Billing staff should not be expected to guess.
If the chart does not support modifier 25, the biller should have a process for asking questions before submission.
For example, the billing team can flag claims when:
- The E/M note is too vague
- The procedure note is incomplete
- The same template language appears on every visit
- The diagnosis codes do not match the story
- Modifier 25 is added to nearly every same-day procedure
- The provider’s decision making is not clear
This type of review helps prevent denials, refunds, and audit problems.
Watch for Payer Denials and Payment Reductions
Some payers may deny or reduce payment for E/M services billed with modifier 25.
Because of this, practices should track payer behavior closely.
The billing team should monitor:
- Denials involving modifier 25
- Requests for medical records
- Downcoded E/M services
- Bundled E/M services
- Reduced payments
- Recoupment notices
- Appeal results
- Payer-specific policy changes
Over time, this helps the office understand which payers are reviewing these claims more closely.
How a Remote Worker Can Help
A remote medical worker can help practices stay organized before and during a modifier 25 audit.
Remote support can assist with:
- Tracking same-day E/M and procedure claims
- Pulling records for review
- Creating modifier 25 worklists
- Checking for missing notes
- Checking for unsigned notes
- Tracking payer denials
- Logging refund requests
- Organizing audit packets
- Following up on appeal deadlines
- Updating task lists
- Documenting payer communication
- Preparing reports for managers
- Helping the billing team monitor trends
This support does not replace coding review or provider documentation. However, it can help the practice stay organized and avoid missed follow-up.
Remote Support Can Help With Internal Audits
Internal audits are easier when someone helps gather and organize the information.
A remote worker can create a monthly list of claims billed with modifier 25. Then, the manager, biller, coder, or provider can review a sample.
That sample may include:
- High-dollar claims
- High-volume procedure combinations
- Claims with denials
- Claims from providers with high modifier use
- Claims from payers requesting records
- Claims involving same-day procedures
As a result, the practice can find problems earlier and correct the workflow.
