Modifier 95
Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system
Use it when
- A service delivered by simultaneous two-way audio and video
- Codes the payer recognises as eligible for telehealth delivery
- Where the payer's convention is modifier 95 rather than a place-of-service change
Do not use it when
- Audio-only encounters, which have their own codes and modifiers
- Asynchronous store-and-forward services
- Services the payer does not recognise as telehealth-eligible
- Where the payer requires a place-of-service code instead of a modifier
A worked example
A physician conducts an established patient visit over a video platform with the patient at home. Both audio and video are live throughout.
The visit is coded with the appropriate office visit code and modifier 95, with the place of service the payer specifies. Level selection follows the same rules as an in-person visit — medical decision-making or total time.
Had the video failed and the visit continued by telephone alone, modifier 95 would not apply. That encounter is audio-only and is coded differently, usually at lower value.
What decides it
Telehealth coding conventions vary more between payers than almost anything else in billing, and they have changed repeatedly. Some payers want modifier 95 with the usual place of service; others want a telehealth place-of-service code; some want both.
The audio-and-video requirement is not a technicality. Payers audit it, and a video visit that degraded to audio-only is a different service. The record should state the modality actually used rather than the modality intended.
Eligibility is defined by code. A service delivered competently by video is not billable as telehealth if the payer does not list that code as telehealth-eligible, and lists are revised at least annually.

Questions about modifier 95
For a service delivered by real-time interactive audio and video. Both are required — an encounter that is audio-only, or that degraded to audio-only when video failed, does not qualify and is coded through a different path.
It depends on the payer. Some want modifier 95 with the usual place of service, others want a telehealth place-of-service code, and some want both. This varies more between payers than almost anything else in billing.
No. Eligibility is defined by code, and lists are revised at least annually. A service delivered competently by video is not billable as telehealth if the payer does not list that code as eligible.
The same way as in-person visits — by medical decision-making or total time. The modality changes how the service was delivered, not how its level is determined.
