A video visit can produce exactly the same note as an office visit, yet the claim still has to explain how the visit was delivered. That explanation is the job of modifier 95. Added to the service code, it certifies that the visit took place through live, two way audio and video, with the patient and the practitioner speaking to each other in real time.
This guide explains what modifier 95 means, the conditions that must be met before it goes on a claim, and the place of service codes that complete the picture for Medicare. It also covers the audio only visit, which takes modifier 93 instead, the retired GT modifier that still appears in older guides, and the mistakes that most often send telehealth claims back.
What modifier 95 certifies
CPT defines modifier 95 as a synchronous telemedicine service rendered through a real time interactive audio and video telecommunications system. Synchronous is the first word to take seriously. It means both parties are connected at the same moment, talking back and forth as the visit happens.
The patient must be present and actively taking part. A recorded video reviewed later, a portal message exchange, or a chart review after the fact is not a synchronous service, and none of them can carry modifier 95.
The second condition sits inside the definition itself. Both sound and picture are required. A visit that runs on audio alone may be a perfectly good telehealth service, but it is a different service for coding purposes, and it takes a different modifier, covered below.
When modifier 95 belongs on a claim
Three conditions need to line up before modifier 95 is appended. The visit was live, with real time audio and video running throughout. The service is one the payer covers when it is delivered by telehealth. And the practitioner is a clinician type the payer allows to bill telehealth services.
For Medicare, coverage starts with the published List of Telehealth Services, which names the services payable under the Physician Fee Schedule when they are furnished by telehealth. A service that is not on that list is not payable as Medicare telehealth, whatever modifier the claim carries, so the list is the first check on any Medicare telehealth claim.
Most telehealth visit claims are built on evaluation and management codes, and CPT Categories Explained shows how those visit codes are grouped. The clinicians Medicare allows to bill telehealth include physicians, nurse practitioners, physician assistants, clinical psychologists and clinical social workers, among others. State licensing law still applies, and the practitioner generally has to be licensed in the state where the patient is located.
Commercial payers keep their own telehealth lists. They overlap with the Medicare list but rarely match it exactly, which is why the safe habit is to confirm coverage under the payer policy before the claim goes out, not after a denial arrives.
How Medicare uses modifier 95 today
Billers who learned telehealth during the pandemic years are often surprised by current Medicare instructions. On a standard Medicare professional claim, the element that flags the visit as telehealth is now the place of service code, not the modifier. Medicare telehealth guidance directs professional billers to the two telehealth place of service codes in use since January 1, 2024, covered in the next section.
Modifier 95 still has a clear Medicare role on the institutional side. Hospitals report it for outpatient therapy services delivered by telehealth when the therapist is a physical therapist, an occupational therapist or a speech language pathologist employed by the hospital.
None of this makes the modifier obsolete. Medicare Advantage plans and most commercial payers still build their telehealth claims around modifier 95, and many require it on every video visit. Dropping it everywhere because traditional Medicare leans on place of service is a habit that fails claims with almost every other payer.
Place of service codes 02 and 10
Modifier 95 describes how the visit was delivered. The place of service code describes where the patient was while it happened, and payers read the two together.
POS 10 covers telehealth provided in the patient’s home. POS 02 covers telehealth provided anywhere else, such as a clinic, a school or a workplace. Both codes have applied to Medicare professional claims since January 1, 2024.
The choice carries payment consequences. Medicare pays for telehealth services provided to patients in their homes at the non-facility rate, the same rate structure that applies to an office visit. The place of service on the claim is what tells the payer which rate structure fits, so a video visit billed with the wrong place of service misstates the claim even when the modifier is right.
A worked example shows how the two elements combine. A video visit with a patient sitting at home is reported with POS 10 and, for the payers that ask for it, modifier 95. The same visit taken from a workplace or a clinic room takes POS 02 instead. The modifier does not change between the two claims. Only the place of service moves, because only the patient location changed.
Audio only visits take modifier 93
Modifier 93 describes a synchronous telemedicine service delivered by telephone or another real time interactive audio only system. It is the correct signal when video never forms part of the visit.
Medicare permits an audio only visit when the practitioner is able to use video but the patient cannot, or does not consent to, using it, with the patient in their home. Audio only delivery is also an accepted route for behavioral and mental health services, again with the patient at home.
Rural health clinics and federally qualified health centers can report audio only visits with modifier 93 or with modifier FQ, the audio only modifier Medicare created for those clinic types.
The working rule is simple. Live video takes modifier 95 wherever the payer asks for a modality modifier. Sound alone takes modifier 93. If a video visit fails partway through and continues as a phone call, the visit that was actually delivered is audio only, and the claim should describe it that way.
The GT modifier, and why searches still find it
Older billing guides, and older staff habits, still carry the GT modifier. GT described the same ground modifier 95 now covers, a telehealth service delivered through interactive audio and video, and for years it was the standard flag on a telehealth claim.
Medicare retired GT from ordinary professional claims in 2018, when place of service reporting took over the job. One narrow use survives. Critical access hospitals billing under the optional payment Method II report their distant site telehealth services on institutional claims with GT.
Some commercial payers and state Medicaid programs kept GT in their own policies for longer, and a current payer policy may still name it. Treat any GT instruction in an old internal guide as a prompt to check the payer current telehealth policy again.
Every payer writes its own telehealth rules
Telehealth shows wider payer variation than almost any other part of billing. Traditional Medicare leans on place of service for professional claims and reserves modifier 95 mainly for hospital outpatient therapy on its own claims, while covering the services on its published list.
Commercial payers publish their own policies. Many require modifier 95 on every telehealth claim. Some still accept GT or GQ as informational modifiers. Audio only coverage ranges from broad to behavioral health only, and place of service expectations do not always match Medicare.
Medicare Advantage plans must cover what Medicare covers, but they run their own claim edits, so their modifier instructions can differ from traditional Medicare. Medicaid programs set telehealth rules state by state, on state timetables.
The durable protection is a payer matrix: one row per payer, showing the modifier, the place of service and the audio only rule that payer currently publishes. It takes an afternoon to build and prevents a steady stream of claim rework.
Mistakes that send telehealth claims back
- Modifier 95 on a visit that ran audio only. The claim reports video that never happened. Modifier 93 is the correct signal.
- A place of service code that does not match where the patient was, such as POS 11 for the office when the patient took the visit from home.
- A service that is not on the payer telehealth list for that year, billed as though listing made no difference.
- GT on a Medicare professional claim, years after Medicare stopped using it there.
- A visit note that never records the modality, the patient location, or the patient consent to a telehealth visit. Reviewers ask for all three.
Most of these errors surface as denials or quiet underpayments rather than clean rejections. The guide to why medical claims get denied explains how to read the denial reason on a remittance and decide between a corrected claim and an appeal.
Frequently asked questions
Does modifier 95 change the payment amount?
No. The modifier reports how the visit was delivered. Under Medicare, the place of service code drives the rate structure, and visits delivered to patients in their homes are paid at the non-facility rate. Commercial payers set their own rates, but the modifier itself states modality, not price.
Can modifiers 95 and 93 appear on the same claim line?
No. One visit has one modality. A visit delivered with live video takes modifier 95 where a modifier is required, and a visit delivered by audio alone takes modifier 93. If the video failed and the visit continued by phone, report the visit that actually happened.
Is modifier 95 a CPT modifier or a HCPCS modifier?
Modifier 95 is a CPT modifier, maintained as part of the CPT code set. What Is a CPT Code explains how CPT codes and modifiers work together on a claim, and how the CPT set differs from HCPCS Level II.
