Telemedicine has transformed the healthcare landscape, offering unprecedented access to care for patients across geographic and socioeconomic barriers. By leveraging telecommunications technology, healthcare providers can deliver remote evaluation, diagnosis, and treatment, enhancing convenience and flexibility for both patients and clinicians. However, the rapid expansion of telehealth, particularly catalyzed by the COVID-19 public health emergency, has introduced significant complexity in billing and reimbursement practices. Telemedicine-specific billing code changes have become a critical focus for healthcare providers, administrators, and policymakers as they navigate an evolving regulatory and reimbursement environment. This article provides a comprehensive exploration of telemedicine-specific billing code changes, their historical context, recent updates, implications for providers, and future trends.
Historical Context of Telemedicine Billing
Early Beginnings of Telemedicine Reimbursement
The concept of telemedicine dates back to the 1920s, envisioned as a virtual alternative to physician house calls. However, practical implementation required technological advancements, which emerged mid-century when NASA developed systems to provide medical care to astronauts in space. By the late 1990s, the Centers for Medicare & Medicaid Services (CMS) began reimbursing for telemedicine services, initially with significant limitations, primarily for patients in rural areas. These early restrictions included geographic constraints, specific originating sites (e.g., hospitals or clinics), and a limited set of billable services, which hindered widespread adoption, particularly among private practice physicians, including specialties like allergy care.
Barriers to Adoption
Before the COVID-19 pandemic, uncertainty surrounding insurance coverage and reimbursement policies posed a major barrier to telemedicine adoption. Providers faced challenges such as inconsistent payer policies, limited eligible services, and complex billing requirements. For example, Medicare required that telehealth services be delivered via live, interactive audiovisual transmission, with specific modifiers like GT (for live interactive telemedicine) or GQ (for store-and-forward telemedicine) to indicate the service type. These restrictions, coupled with concerns about lower reimbursement rates compared to in-person visits, deterred many providers from fully embracing telehealth.
The Impact of COVID-19 on Telemedicine Billing
Emergency Policy Changes
The COVID-19 public health emergency, declared in 2020, marked a turning point for telemedicine. To ensure access to healthcare while minimizing in-person contact, CMS and other payers rapidly expanded telehealth coverage and reimbursement policies under emergency waivers, such as those authorized by the 1135 waiver authority and the Coronavirus Preparedness and Response Supplemental Appropriations Act. Key changes included:
- Removal of Geographic Restrictions: Medicare allowed telehealth services to be provided regardless of the patient’s location, including their homes, eliminating the requirement for patients to be at designated originating sites.
- Expanded Eligible Providers: All Medicare-eligible billing providers, including non-physician practitioners like physical therapists and clinical psychologists, could deliver and bill for telehealth services.
- Audio-Only Services: CMS permitted audio-only telehealth for certain services, particularly for patients unable to use or access video technology, a significant departure from prior requirements for audiovisual interaction.
- Payment Parity: Many payers, including Medicare, began reimbursing telehealth services at rates equivalent to in-person visits, incentivizing providers to adopt virtual care.
These changes facilitated a surge in telehealth adoption, enabling providers to offer virtual care to new, out-of-state, and out-of-network patients. For instance, allergists innovated by managing conditions like anaphylaxis remotely, reducing the need for emergency department visits during the pandemic.
Introduction of New Billing Codes
To accommodate the expanded scope of telehealth, CMS and the American Medical Association (AMA) introduced and revised Current Procedural Terminology (CPT) and Healthcare Common Procedure Coding System (HCPCS) codes. Notable additions included:
- Virtual Check-Ins: HCPCS code G2012 for brief communication technology-based services (5-10 minutes) and G2010 for remote evaluation of patient-submitted images or videos. These codes required an established patient-provider relationship and patient consent.
- E-Visits: CPT codes 99421-99423 for online digital evaluation and management (E/M) services conducted via patient portals, and HCPCS codes G2061-G2063 for non-physician providers, covering cumulative time over seven days (5-10, 11-20, and 21+ minutes).
- Telephone E/M Codes: CPT codes 99441-99443 for telephone-based E/M services, allowing physicians to bill for audio-only interactions with established patients.
These codes provided a framework for billing a wider range of telehealth services, reflecting the diverse modalities (synchronous audio-video, audio-only, and asynchronous) used during the pandemic.
Recent Telemedicine-Specific Billing Code Changes (2024-2025)
The 2025 CPT Code Updates
In 2025, the AMA introduced a new set of telemedicine-specific CPT codes (98000-98016) to replace the telephone E/M codes (99441-99443) and better differentiate telemedicine services from in-person care. These codes aim to address the unique cost structure of telehealth, which often involves lower overhead (e.g., no front desk staff or facility costs) compared to in-person visits. Key features of the new codes include:
- Audiovisual E/M Codes (98000-98007): For synchronous audio-video telehealth visits, covering new and established patients, with code selection based on time or medical decision-making (MDM), similar to in-person E/M codes (99202-99215).
- Audio-Only E/M Codes (98008-98015): For synchronous audio-only visits, applicable to new and established patients, replacing the retired 99441-99443 codes. These codes are time-based, ranging from brief to extended consultations.
- Virtual Check-In Code (98016): Replaces HCPCS code G2012 for brief, patient-initiated virtual check-ins (5-10 minutes), not related to a recent or upcoming E/M service.
However, CMS declined to adopt most of these new CPT codes (98000-98015) for Medicare reimbursement, opting instead to continue using in-person E/M codes (99202-99215) with appropriate modifiers for telehealth services. The exception is CPT code 98016, which CMS adopted to replace G2012 for virtual check-ins. This decision has created confusion, as commercial payers and Medicaid plans have inconsistently adopted the new codes, requiring providers to verify payer-specific policies.
Modifiers and Place of Service (POS) Codes
Modifiers play a critical role in telehealth billing to indicate the service modality and location. Key modifiers for 2025 include:
- Modifier 93: Indicates synchronous audio-only telehealth services, used when the provider is capable of audio-video but the patient cannot or does not consent to video.
- Modifier 95: Denotes synchronous audio-video telehealth services.
- Modifier FQ: Used by Federally Qualified Health Centers (FQHCs) and Rural Health Clinics (RHCs) for audio-only services.
- Modifier GT: Specific to Critical Access Hospitals (CAHs) billing under Method II or for certain demonstration projects (e.g., Alaska or Hawaii).
POS codes are equally important, as they affect reimbursement rates:
- POS 02: Telehealth provided other than in the patient’s home.
- POS 10: Telehealth provided in the patient’s home.
Providers must ensure accurate use of POS codes and modifiers to avoid claim denials, as reimbursement rates may differ based on the patient’s location and service modality.
Medicare Policy Extensions
The Full-Year Continuing Appropriations and Extensions Act of 2025 extended Medicare’s pandemic-era telehealth flexibilities through September 30, 2025, including:
- Coverage of audio-only services for mental health and certain non-behavioral services (e.g., speech therapy, nutritional counseling).
- No geographic restrictions for patients or providers.
- Continued eligibility for FQHCs and RHCs as distant site providers.
However, CMS has emphasized that audio-only services require providers to be capable of audio-video technology and patients to either lack access to or decline video use, with documentation supporting these conditions.
Implications for Healthcare Providers
Challenges in Compliance
The evolving telehealth billing landscape presents several challenges:
- Payer Variability: While Medicare has clear guidelines, commercial payers, Medicare Advantage, and state Medicaid programs have inconsistent policies. Providers must verify coverage and coding requirements for each payer, which can be time-consuming.
- Documentation Requirements: Accurate documentation of service modality, duration, patient consent, and clinical justification is critical to avoid audits and claim denials. For example, audio-only visits require documentation of the patient’s inability or refusal to use video.
- Billing Errors: Common mistakes include using incorrect codes, omitting modifiers, or misaligning POS codes with payer policies, leading to delayed or denied reimbursements.
Opportunities for Innovation
Despite these challenges, telemedicine billing code changes have spurred innovation. Providers are re-evaluating which services can be safely delivered virtually, such as remote monitoring for chronic conditions or virtual management of acute conditions like anaphylaxis. The introduction of Remote Patient Monitoring (RPM) codes (e.g., 99453, 99454) has enabled reimbursement for continuous data tracking, particularly for maternal care and chronic disease management.
Financial Considerations
While telehealth services often have lower overhead costs, reimbursement rates may not always reflect payment parity with in-person visits, especially as payers adjust rates to account for reduced operational expenses. Providers must monitor payment levels to ensure compliance with state payment parity laws and contractual agreements.
Future Trends in Telemedicine Billing
Post-Pandemic Landscape
As the COVID-19 public health emergency waivers expire, the future of telehealth billing remains uncertain. The extension of Medicare flexibilities through September 2025 provides temporary stability, but long-term policies depend on Congressional action. Experts anticipate that telehealth will remain a core component of healthcare delivery, particularly in specialties like allergy, mental health, and primary care, where virtual care has proven effective.
Potential Code Evolution
The AMA’s introduction of telemedicine-specific CPT codes signals a shift toward standardizing telehealth billing. Future updates may include:
- Additional codes for emerging telehealth modalities, such as asynchronous store-and-forward services or hybrid care models.
- Refinement of E/M coding to better align with telehealth’s unique workflow and documentation needs.
- Greater adoption of RPM and digital health codes to support proactive care management.
Advocacy and Policy Development
Robust advocacy from organizations like the American Academy of Allergy, Asthma & Immunology (AAAAI) and the American Academy of Family Physicians (AAFP) will be crucial to ensure that telehealth policies promote access and equity. Providers are encouraged to engage with professional societies to stay informed and influence policy changes.
Frequently Asked Questions
What are the new telemedicine-specific CPT codes introduced in 2025, and how do they differ from previous codes?
In 2025, the AMA introduced CPT codes 98000-98016 to replace telephone E/M codes (99441-99443) and better differentiate telehealth services. Codes 98000-98007 cover audiovisual E/M visits, 98008-98015 cover audio-only visits, and 98016 replaces HCPCS G2012 for virtual check-ins. These codes align with in-person E/M code structures (time or MDM-based) but are specific to telehealth modalities. However, CMS has not adopted most of these codes (except 98016) for Medicare, preferring in-person E/M codes with modifiers.
How should providers bill for audio-only telehealth services in 2025?
For Medicare, providers should use in-person E/M codes (e.g., 99202-99215) with modifier 93 for audio-only services, documenting the patient’s inability or refusal to use video and the provider’s capability for audio-video. Commercial payers may accept the new audio-only codes (98008-98015), but providers must verify payer policies. Accurate documentation of service duration and modality is essential.
What are the key differences between POS 02 and POS 10, and why do they matter?
POS 02 indicates telehealth services provided when the patient is not at home (e.g., at a clinic), while POS 10 is used when the patient is at home. These codes affect reimbursement rates, as Medicare and other payers may adjust payments based on the patient’s location. Using the correct POS code is critical to avoid claim denials.
Are there specific billing codes for Remote Patient Monitoring (RPM) in telehealth?
Yes, CPT codes 99453 and 99454 are used for RPM, covering setup and ongoing monitoring of devices that track clinical data. These codes are particularly relevant for maternal care and chronic disease management. Providers must ensure compliance with payer-specific rules, such as monthly billing limits and documentation requirements.
How can providers stay compliant with evolving telehealth billing regulations?
Providers should regularly check CMS and payer websites for updates, subscribe to professional organizations like the AAFP or AAPC for coding resources, and partner with experienced medical billing companies to navigate complex requirements. Accurate documentation, correct code selection, and payer policy verification are key to compliance.
