In the USA telehealth has fundamentally reshaped how US healthcare providers deliver care and how they get paid for it. Since the COVID-19 public health emergency accelerated virtual care adoption, telehealth medical billing has become one of the most complex and frequently misunderstood areas of healthcare revenue cycle management. Whether you are a primary care physician, a specialist, a behavioral health provider, or a hospital system, understanding telehealth billing is no longer optional, it is essential to your financial survival.
This guide was written specifically for US healthcare professionals who want a definitive, practical reference for telehealth billing in 2025. We cover CPT codes, Medicare and Medicaid telehealth rules, audio-only billing, HIPAA-compliant platforms, modifier usage, claim submission, and the most common denial reasons.
At House of Outsourcing, we have helped hundreds of practices across the country streamline their telehealth medical billing, reduce denials, and recover revenue they did not even know they were leaving on the table.
�� Telehealth By The Numbers (2025) |
• Over 38 million Medicare beneficiaries used telehealth services in 2024 (CMS data) |
• Telehealth visits increased 63x compared to pre-pandemic levels at peak adoption |
• Average denial rate for telehealth claims: 12–18% (vs. 5–8% for in-person visits) |
• Providers leave an estimated $3.2 billion in telehealth revenue uncollected annually |
• CMS extended most telehealth flexibilities through December 31, 2026 |
Telehealth medical billing refers to the process of submitting and collecting payment for healthcare services delivered remotely through video, telephone, or secure digital messaging rather than in a traditional face-to-face setting. While the clinical encounter may look different, the billing process involves the same core elements, accurate coding, proper modifiers, payer-specific rules, and timely claim submission.
The key distinction between telehealth billing services and traditional billing lies in the additional layers of complexity, place of service (POS) codes that differ by payer, originating site vs. distant site rules, audio-only service codes, and a constantly evolving regulatory landscape that can change with each new CMS rulemaking cycle.
Tip: |
Always verify telehealth coverage before the patient’s visit. Payer policies including Medicare Advantage plans vary widely, and a service that is covered under traditional Medicare may not be covered under a specific MA plan. A 2-minute eligibility check can prevent a $150+ write-off. |
Medicare is the dominant payer for telehealth services, and the Centers for Medicare & Medicaid Services (CMS) sets the foundational rules that most other payers follow. The Medicare telehealth billing framework has undergone significant changes since 2020, with most PHE flexibilities now permanently adopted or extended.
According to CMS, Medicare covers telehealth services under Section 1834(m) of the Social Security Act. The provider must be an eligible distant site practitioner, which includes physicians, nurse practitioners, physician assistants, clinical psychologists, licensed clinical social workers, and several other provider types.
| Rule / Requirement | 2025-2027 Status | Notes & Guidelines |
|---|---|---|
| Geographic waiver (rural-only restriction) | Waived through Dec 31, 2027 | Patients can be seen from any location including home |
| Audio-only coverage for mental health | Permanent (with conditions) | Patient must have prior in-person visit or agree to one |
| Federally Qualified Health Centers (FQHCs) | Covered through 2027 | As distant site providers |
| In-person requirement (mental health) | Waived through Dec 31, 2027 | Originally required within 6 months of initial telehealth visit; currently phased out until 2028 |
| POS Code for patient home | POS 10 | New in 2022; use when patient is at home |
| POS Code for other telehealth | POS 02 | When patient is NOT at home |
| Originating site fee (G0468) | Paid when applicable | Rural originating sites only post-PHE in most cases |
Selecting the correct CPT code is the foundation of accurate telehealth medical billing. The code set for telehealth services mirrors many in-person evaluation and management (E&M) codes, but the context, documentation requirements, and modifier rules differ substantially.
| CPT Code | Service Description | Time (Typical) | 2025 Fee (Medicare Avg.) |
|---|---|---|---|
| 99202 | New patient office/telehealth visit, low complexity | 15–29 min | $76–$110 |
| 99203 | New patient office/telehealth visit, low-moderate complexity | 30–44 min | $111–$153 |
| 99204 | New patient office/telehealth visit, moderate complexity | 45–59 min | $167–$214 |
| 99205 | New patient office/telehealth visit, high complexity | 60–74 min | $211–$290 |
| 99211 | Est. patient visit, minimal complexity (nurse/staff) | 5 min | $24–$35 |
| 99212 | Est. patient office/telehealth visit, low complexity | 10–19 min | $58–$89 |
| 99213 | Est. patient office/telehealth visit, low-moderate complexity | 20–29 min | $95–$128 |
| 99214 | Est. patient office/telehealth visit, moderate complexity | 30–39 min | $135–$175 |
| 99215 | Est. patient office/telehealth visit, high complexity | 40–54 min | $172–$232 |
| CPT Code | Service Description | Duration |
|---|---|---|
| 99441 | Telephone E&M service, physician/QHP — established patient | 5–10 minutes |
| 99442 | Telephone E&M service, physician/QHP — established patient | 11–20 minutes |

Modifiers are the most misunderstood element of telehealth medical billing services. Applying the wrong modifier, or omitting one entirely is one of the top five reasons telehealth claims are denied or downgraded by payers.
| Modifier | Name | When to Use | Payer |
|---|---|---|---|
| -95 | Synchronous Telemedicine Service | Real-time audio/video telehealth visits | Most commercial + Medicare Advantage |
| -GT | Via Interactive Audio and Video | Medicare FFS telehealth claims (still used on some Part B) | Medicare FFS |
| -GQ | Via Asynchronous Telecommunications | Store-and-forward services (Alaska, Hawaii demonstration) | Medicare FFS |
| -93 | Synchronous Telemedicine Service (audio-only) | When only audio (no video) is used and covered by payer | Select payers |
| -FQ | Service furnished using audio-only communication | Mental health audio-only visits (Medicare) | Medicare |
| CR | Catastrophe/Disaster Related | PHE-related claims (as instructed by CMS) | Medicare PHE |
Medicaid telehealth billing is more complicated than Medicare telehealth billing because Medicaid is a state-administered program. This means coverage rules, eligible services, provider types, and reimbursement rates vary significantly from state to state.
As of 202,6 all 50 states and the District of Columbia cover at least some form of telehealth under Medicaid, according to the Center for Connected Health Policy (CCHP) but what is covered and how it must be billed differs dramatically.
| State Category | Telehealth Coverage Scope | Audio-Only Medicaid | Live Video Required |
|---|---|---|---|
| Full parity states (e.g., CA, NY, TX) | Broad — mirrors in-person coverage | Yes (many) | No — audio covered |
| Moderate parity states (e.g., FL, OH) | Covered for select services | Limited | Often required |
| Limited coverage states | Specific programs/populations only | Rarely | Yes — video required |
| FQHCs & RHCs in all states | Extended telehealth coverage | Per state rules | Varies |
Place of Service codes are a critical and frequently misused component of telehealth billing services. CMS introduced POS 10 in 2022 specifically to distinguish telehealth visits where the patient is located at home, which carries a different reimbursement rate than POS 02.
| POS Code | Description | When to Use | Impact on Reimbursement |
|---|---|---|---|
| POS 02 | Telehealth Provided Other than in Patient's Home | Patient is NOT at home (clinic, employer site, etc.) | Facility rate — lower than non-facility |
| POS 10 | Telehealth Provided in Patient's Home | Patient IS at home during the visit | Non-facility rate — higher reimbursement |
| POS 11 | Office (not telehealth) | Provider at office, in-person visit | Non-facility rate — standard |
| POS 22 | On Campus-Outpatient Hospital | Outpatient hospital-based telehealth (some payers) | Facility rate |
While the core telehealth billing rules apply across all specialties, each clinical area has its own complexities, preferred code sets, and payer-specific considerations. Here is a specialty-by-specialty breakdown of telehealth medical billing best practices.
Primary care telehealth billing primarily uses the E&M code set (99202–99215). Chronic care management (CCM) codes, annual wellness visits, and preventive care codes are also billable via telehealth for Medicare patients. Document medical decision-making (MDM) or total time to support code selection.
Behavioral health is the most telehealth-forward specialty in the US. CMS permanently extended telehealth for mental health services, making this a high-priority area. Use 90832–90837 for psychotherapy and 90791–90792 for psychiatric evaluations. Audio-only is covered for established patients with documented consent.
Cardiology telehealth billing covers follow-up visits for hypertension, CHF, and post-MI management. Remote physiologic monitoring (RPM) codes 99453, 99454, 99457, 99458 are frequently bundled with cardiology telehealth services and can significantly boost per-patient revenue.
Dermatology is a leading specialty for asynchronous (store-and-forward) telehealth. Images are captured and sent to the dermatologist for review. Under Medicare, this is only covered in Alaska and Hawaii through the Federal Telemedicine Demonstration Project, but many commercial payers and state Medicaid programs reimburse it nationally.
Post-surgical follow-ups, physical therapy oversight, and musculoskeletal consultations are the most common orthopedic telehealth visits. Document functional status and treatment plan modifications clearly, as orthopedic telehealth claims face above-average audit rates from commercial payers.
Telestroke and teleneurology services are well-established. G0406, G0407, G0408 cover follow-up inpatient telehealth consultations. For telestroke, G0508 and G0509 cover critical care telehealth. These codes have specific documentation requirements that should be reviewed against CMS transmittals annually.

Remote patient monitoring is one of the fastest-growing segments of telehealth medical billing services. RPM allows providers to monitor patients’ physiologic data, blood pressure, glucose, weight, oxygen saturation using digital devices, and bill separately for the clinical work involved.
| RPM CPT Code | Service Description | Billing Frequency | Medicare 2025 Rate (Approx.) |
|---|---|---|---|
| 99453 | Setup and patient education for RPM device | One-time per episode | $19–$21 |
| 99454 | Device supply with daily recording/transmission | Monthly (30-day period) | $54–$64 |
| 99457 | First 20 min of RPM management per month | Monthly | $50–$58 |
| 99458 | Additional 20 min of RPM management per month | Monthly (add-on to 99457) | $41–$47 |
| 99091 | Collection and interpretation of physiologic data | Monthly (30+ min) | $56–$65 |
HIPAA compliance is a non-negotiable element of telehealth billing. From the platform used for the visit to the billing software transmitting claim data, every component of the telehealth workflow must meet HIPAA standards.
The HHS Office for Civil Rights (OCR) enforces HIPAA and has increased telehealth audits since 2022. Key compliance areas for telehealth medical billing services include:
A clean telehealth medical billing workflow significantly reduces denials and accelerates reimbursement. Here is the process that high-performing telehealth practices follow:
Telehealth claim denials cost US providers an estimated $262 billion annually in rework costs. For telehealth medical billing specifically, denial rates are disproportionately high due to the complexity of the rules. Here are the most common denial reasons and proven resolution strategies.
| Denial Reason | Root Cause | Prevention / Fix |
|---|---|---|
| Service not covered via telehealth | Payer doesn't cover that CPT via telehealth | Verify coverage before visit; check payer's telehealth approved code list |
| Wrong or missing modifier | Missing -95, -GT, or -FQ | Build modifier logic into billing workflow by service type |
| Wrong POS code | POS 02 used instead of POS 10 or vice versa | Train front desk to document patient location at visit start |
| Duplicate claim | Telehealth visit billed like in-person (POS 11) | Separate telehealth claim template from in-person template in PM system |
| Non-covered originating site | Urban originating site billed post-PHE | Only bill G0468 for qualifying rural originating sites |
| Consent not documented | No telehealth consent in chart | Implement pre-visit consent workflow; scan/attach to chart |
| Provider not enrolled for telehealth | Payer requires separate telehealth credentialing | Check credentialing status with each payer before billing |
| Timely filing exceeded | Claim submitted late | Set automated billing alerts for DOS-based filing deadlines |

You cannot submit a clean telehealth claim if you are not properly credentialed with each payer for telehealth services. While Medicare credentialing for telehealth largely follows standard Part B enrollment, commercial payers often require additional attestation or separate telehealth credentialing.
For group practices and health systems, telehealth medical billing services introduce additional complexity around provider assignment, incident-to billing, split/shared visits, and cross-state licensing. These are areas where billing errors — and subsequent audits — are most likely to occur.
Incident-to billing (where a supervising physician bills for services provided by an NPP) is permitted for telehealth under Medicare, but the supervision requirements are different. Direct supervision is required, which in a telehealth context means the supervising physician must be immediately available via audio/video not just a phone call away.
Split/shared E&M visits (between a physician and an NPP in the same group) are permitted via telehealth. Billing is done under the provider who performs the substantive portion. As of 2025, the substantive portion is defined by total time — the provider who spends the majority of the combined time bills the service.
The right technology stack is foundational to scalable telehealth billing. From HIPAA-compliant video platforms to billing software with telehealth-specific claim templates, technology choices directly impact both revenue and compliance outcomes.
| Tool Category | Examples | Billing Impact |
|---|---|---|
| HIPAA-Compliant Telehealth Platforms | Zoom for Healthcare, Doxy.me, Teladoc, Doximity | Required for HIPAA compliance; BAA must be in place |
| EHR with Telehealth Integration | Epic, Athenahealth, eClinicalWorks, Kareo | Automates visit documentation and reduces coding time |
| Practice Management / Billing Software | AdvancedMD, Tebra, Waystar, Availity | Telehealth claim templates, modifier auto-apply, ERA management |
| RPM Device Vendors | iHealth, Withings, Transtek, Body Trace | Device data feeds into clinical documentation for RPM billing |
| Eligibility Verification Tools | Availity, Change Healthcare, Waystar | Instant telehealth coverage verification pre-visit |
| Denial Management Platforms | Waystar, Experian Health, nThrive | Telehealth-specific denial tracking and appeal workflow |
Getting paid for telehealth services is not just about avoiding denials, it is about proactively building a billing workflow that maximizes legitimate reimbursement for every virtual encounter. Here are proven strategies used by high-performing telehealth practices.
Remote patient monitoring codes generate monthly recurring revenue on top of your E&M visits. A practice with 100 chronic disease patients enrolled in RPM can generate $6,000–$12,000 in additional monthly revenue from the 99454 and 99457 codes alone.
CCM codes (99490, 99491, 99487, 99489) can be billed in months when at least 20 minutes of care coordination time is documented. Many telehealth practices fail to capture this revenue despite routinely providing qualifying services.
A monthly audit of POS 02 vs. POS 10 usage can identify systematic under-billing. If your practice is routinely using POS 02 when patients are calling from home, you may be losing 15–30% on E&M reimbursement.
Medicare and most commercial payers flag practices with unusually high telehealth utilization ratios. Maintaining a documented, clinically justified telehealth-to-in-person ratio protects against post-payment audit risk while optimizing scheduling.
Telehealth billing services in 2026 primarily use standard E&M codes (99202–99215) with appropriate modifiers (-95 for video, -FQ for audio-only mental health under Medicare). For behavioral health, use 90832–90837. For remote patient monitoring, use 99453, 99454, 99457, and 99458. Always pair these codes with POS 10 (patient at home) or POS 02 (other telehealth location) to ensure correct reimbursement.
Yes — as of 2025, Medicare covers telehealth services for beneficiaries in all states and geographic areas, thanks to extensions of the PHE flexibilities through December 31, 2026. Prior to the PHE, Medicare telehealth was restricted to rural geographic areas. The extension applies to both Medicare fee-for-service and most Medicare Advantage plans, though MA plans can impose their own additional requirements.
POS 02 (Telehealth Provided Other than in Patient’s Home) is used when the patient is at a location other than their home, such as a clinic or worksite. POS 10 (Telehealth Provided in Patient’s Home) is used when the patient receives care from home. POS 10 triggers the non-facility reimbursement rate, which is typically 15–30% higher than the facility rate associated with POS 02. This distinction is one of the most impactful — and frequently overlooked — factors in telehealth revenue optimization.
Yes, but with conditions. For general medical services, Medicare covers audio-only telephone visits using CPT codes 99441–99443, but these are subject to the patient initiating the call and additional documentation requirements. For behavioral health specifically, Medicare permanently covers audio-only telehealth services as of 2022, but requires that the patient has had (or agrees to have) an in-person visit within a specified timeframe. Modifier -FQ is required for audio-only mental health visits.
The most common modifiers for telehealth billing are: -95 (synchronous telemedicine service rendered via real-time interactive audio/video, used by most commercial payers and Medicare Advantage); -GT (via interactive audio and video, used for some Medicare fee-for-service claims); -FQ (service furnished using audio-only communication, for Medicare mental health audio-only); and -93 (synchronous telemedicine via audio-only, used by some commercial payers). Always check payer-specific requirements before applying modifiers, as incorrect modifier use is a top cause of telehealth claim denials.
