Understanding Telehealth Billing in 2026

Telehealth billing refers to submitting medical claims for services delivered through real-time audio-video communication technologies instead of traditional in-person visits.

Telehealth services may include:

• Virtual consultations

• Remote patient monitoring

• Behavioral health visits

• Chronic care management

• Follow-up evaluations

To correctly bill telehealth services, providers must use the correct combination of:

• CPT or HCPCS codes

• Telehealth modifiers

• Place of Service (POS) codes

These elements inform insurers that the healthcare service was delivered remotely.

What Is Modifier GT in Telehealth Billing?

Modifier GT indicates that a healthcare service was delivered through interactive audio and video telecommunications systems.

Definition:

Modifier GT means a service was provided through interactive audio and video telecommunication systems.

When Modifier GT Is Used

Modifier GT is often required by:

• Medicaid programs

• Some commercial insurance payers

• Institutional billing settings

Example:

A provider conducts a telehealth office visit for an established patient using CPT code 99213. The claim would be submitted as 99213 with modifier GT to indicate that the service was performed through telehealth.

Key Notes for 2026

Many Medicare claims now prefer modifier 95. However, some payers still accept or require modifier GT. Billing teams should always verify payer-specific telehealth billing rules.

What Is Modifier 95?

Modifier 95 is currently the most widely used modifier for Medicare telehealth billing.

Definition:

Modifier 95 indicates a synchronous telemedicine service delivered using real-time audio and video telecommunications technology.

Why Modifier 95 Matters

CMS uses modifier 95 to confirm that a healthcare service:

• Was delivered through live video communication

• Meets telehealth eligibility requirements

• Appears on the Medicare telehealth services list

Example:

A physician performs a telehealth follow-up visit for an established patient using CPT code 99214. The claim may be submitted as 99214 with modifier 95 and POS 02 to indicate that the visit occurred through telehealth technology.

Modifier GT vs Modifier 95: Key Differences

Feature	Modifier GT	Modifier 95
Usage	Older telehealth modifier	Current Medicare preferred modifier
CMS preference	Limited use	Preferred by CMS
Payer usage	Medicaid and some private insurers	Medicare and most private insurers
Technology requirement	Interactive audio-video	Real-time audio-video

Practical billing tip:

Always verify payer guidelines because some insurers accept both modifiers while others require specific telehealth modifiers.

POS 02 in Telehealth Billing

POS 02 represents telehealth services delivered when the patient is located somewhere other than their home.

Definition:

POS 02 indicates telehealth services provided using telecommunications technology when the patient is outside their home.

When to Use POS 02

POS 02 is used when the patient receives telehealth services at locations such as:

• Hospitals

• Clinics

• Nursing facilities

• Community health centers

Example:

A patient located at a rural clinic attends a telehealth consultation with a specialist. The provider bills CPT code 99213 with modifier 95 and POS 02 to show the service was delivered remotely while the patient was at a healthcare facility.

POS 10 vs POS 02: Important 2026 Update

CMS introduced POS 10 to identify telehealth services provided when the patient is at home.

POS CodeDescriptionPOS 02Telehealth provided when the patient is outside the homePOS 10Telehealth provided when the patient is at home

Why this matters:

Different place-of-service codes can impact reimbursement rates and determine whether claims are processed as facility or non-facility services.

Telehealth Billing Requirements in 2026

To ensure compliant telehealth claims, providers must meet several requirements.

Eligible CPT Codes

Not every CPT code qualifies for telehealth billing. CMS maintains an updated telehealth services list each year.

Common telehealth CPT codes include:

• 99202–99215 for evaluation and management visits

• 90791 for psychiatric diagnostic evaluation

• 90834 and 90837 for psychotherapy

• 99457 for remote patient monitoring

Technology Requirements

Most telehealth services require real-time audio and video communication through HIPAA-compliant platforms.

Some payers may allow audio-only services for behavioral health visits.

Documentation Requirements

Providers should document:

• Patient consent for telehealth services

• Technology platform used

• Patient location

• Provider location

• Duration of visit

• Medical decision-making details

FAQs: Telehealth Billing — Modifier GT, Modifier 95, POS 02 Updates

What is modifier 95 in telehealth billing? +

Modifier 95 is used to show that a covered healthcare service was delivered through real-time interactive audio and video telecommunication technology. It is commonly used for Medicare telehealth billing and helps identify synchronous telemedicine services on eligible CPT codes.

What is modifier GT used for in telehealth billing? +

Modifier GT indicates that a healthcare service was provided through interactive audio and video telecommunications systems. Although modifier 95 is more commonly used today, some Medicaid programs, institutional settings, and private insurers still require modifier GT for telehealth claims.

What is the difference between modifier GT and modifier 95? +

The main difference is payer preference and billing usage. Modifier GT is an older telehealth modifier still used by some Medicaid and commercial payers, while modifier 95 is the more common modifier for Medicare and many private insurers. Both generally refer to services delivered through live audio-video communication, but billing teams must follow payer-specific claim rules.

What is POS 02 in telehealth billing? +

POS 02 means the telehealth service was provided when the patient was located somewhere other than their home. This may include a hospital, clinic, nursing facility, or another healthcare site.

What is the difference between POS 02 and POS 10? +

POS 02 is used when the patient receives telehealth services outside the home, while POS 10 is used when the patient receives telehealth services at home. This distinction matters because it can affect reimbursement, claim processing, and whether the service is treated as facility or non-facility based billing.

Can modifier GT and modifier 95 be billed together? +

Providers should confirm that the code is eligible for telehealth billing under current payer guidelines before submitting the claim.

Why do telehealth claims get denied? +

Telehealth claims are often denied because of incorrect modifier use, wrong POS codes, missing documentation, non-covered CPT codes, or payer-specific billing errors. Common mistakes include using POS 02 instead of POS 10, adding the wrong telehealth modifier, or failing to document patient consent and location details.

Does telehealth billing require audio and video? +

Many telehealth services require real-time audio and video communication, especially when billed with modifier 95 or GT. However, some payers may allow audio-only billing for specific services such as behavioral health. Providers should always verify payer policy because audio-only coverage varies by insurer and service type.
