Telehealth billing continues to play a critical role in healthcare delivery in 2025, helping bridge the gap for patients in rural, underserved, and mobility-restricted communities. As the adoption of telehealth grows, so do the complexities surrounding telehealth billing. In response, CMS has introduced new policies and clarified existing ones to streamline reimbursement processes and minimize misuse. For healthcare providers and billing professionals, understanding the evolving telehealth billing guidelines is essential to stay compliant, avoid costly denials, and maintain financial viability in a hybrid care environment. Implementing efficient telehealth billing practices has never been more crucial to ensure seamless revenue cycle management.
Key Changes in Telehealth Billing for 2025
Expansion of Eligible Providers
More healthcare providers can now offer and bill for telehealth services under Medicare in 2025. These include audiologists, physical therapists, occupational therapists, speech-language pathologists, and clinical social workers. This expansion enables better access to diverse healthcare services for patients needing long-term care, rehabilitation, or therapy. Practices must ensure that all providers are properly credentialed and understand billing rules specific to their scope, which have become more nuanced and critical for reimbursement accuracy. This expansion is particularly crucial as it addresses gaps in service delivery, especially for populations with limited access to in-person care.
Modifications to Covered Services
CMS has updated the list of covered services, now including chronic care management, intensive behavioral therapy, and remote physiologic monitoring for broader use. These additions reflect the growing recognition that many conditions—especially chronic and mental health ones—are effectively treated via virtual care. Providers must cross-reference this list regularly to ensure services rendered match what’s eligible for reimbursement, especially as changes to this list may roll out quarterly. This proactive approach helps maintain compliance and avoid underbilling, ensuring that practices don’t miss out on reimbursement for eligible services.
Reimbursement Rate Adjustments
Reimbursement rates have been fine-tuned to better reflect the complexity and value of telehealth services. While some services are now reimbursed at parity with in-person visits, others have seen rate decreases. These rate changes take into account clinical time, medical decision-making, and modality (video vs. audio). It’s vital for billing professionals to stay informed on fee schedule changes so they can adjust coding and documentation strategies accordingly. Keeping an eye on reimbursement trends will allow practices to adapt quickly and optimize revenue while maintaining compliance.
Changes in Geographic and Site Restrictions
Temporary waivers continue through March 31, 2025, allowing patients to receive care from home regardless of geographic location. However, providers must still document originating and distant site locations accurately. Beyond 2025, CMS may reintroduce previous geographic restrictions, so clinics need scalable workflows that can adapt quickly to changes without disrupting service continuity or revenue flow. Being prepared for such shifts can ensure practices remain compliant while offering uninterrupted telehealth services to patients in need.
Telehealth Coding and Documentation Requirements
Proper coding and documentation are more crucial than ever. Here’s a detailed list of what’s required in 2025:
- Use POS Codes 02 and 10: POS 02 is for telehealth delivered outside the patient’s home. POS 10 is specifically for services delivered at the patient’s home. Correctly coding these POS locations helps ensure proper reimbursement and compliance.
- Include Modifier 95: Use Modifier 95 for synchronous telehealth services delivered via audio-video technology. This modifier signals that the service was conducted through telecommunication, and failing to use it can lead to denials.
- Document the Telehealth Modality: Specify whether the visit was conducted via audio-only or audio-video. This affects both compliance and billing rates, so clear documentation is essential for accurate coding.
- Record Duration and Time Spent: Time-based billing is key for many E/M codes. Always log total visit time and time spent on counseling when applicable. Properly recording time ensures accurate billing, especially for complex cases.
- Patient Consent: Document verbal consent before initiating telehealth services, especially for new patients or Medicare beneficiaries. This consent is a mandatory requirement to ensure compliance with CMS policies.
- Medical Necessity: Justify why telehealth was appropriate for the visit instead of an in-person appointment, especially for high-complexity cases. Medical necessity documentation protects against denials and demonstrates that telehealth was the best modality for care.
- Technology Used: Note the platform or system used (e.g., Zoom, Doxy.me) and any technical limitations that may have impacted care delivery. This transparency supports documentation of the visit’s integrity and compliance.
Medicare and Medicaid Telehealth Billing Policies
CMS 2025 Final Rule Overview
The CMS 2025 Final Rule extends key telehealth flexibilities. Providers can continue offering behavioral health services via audio-only when necessary. Direct supervision may now be provided virtually in real-time, offering flexibility for remote medical teams. Additionally, many temporary codes have been permanently adopted into Medicare’s list of reimbursable services. Practices must review the updated Physician Fee Schedule and stay aligned with CMS policies to avoid claim denials and recoupment demands. Ensuring accurate and up-to-date knowledge of these rules is critical for staying compliant and securing payment.
Medicaid Variability Across States
Unlike Medicare, Medicaid telehealth policies vary significantly by state. While some states continue to support expansive telehealth use, others are rolling back pandemic-era flexibilities. Key differences include eligible providers, covered services, and patient location rules. Billing teams must consult their state Medicaid program directly to understand requirements for documentation, coding, and platform compliance to ensure accurate claims submission. This variability across states requires flexibility and diligence in staying compliant with each state’s evolving telehealth rules.

Telehealth Compliance and Audit Readiness
Risk Areas for Telehealth Billing in 2025
The Office of Inspector General (OIG) has flagged several telehealth risk areas, including:
- Billing for ineligible providers or services: Billing for services that aren’t covered or provided by non-eligible practitioners can result in audit findings and repayment demands. Practices should ensure full eligibility verification for telehealth providers.
- Submitting claims for audio-only visits without proper documentation: Audio-only visits require meticulous documentation that supports their use and justifies medical necessity, particularly for behavioral health services.
- Duplicate billing for in-person and telehealth care for the same service: Submitting claims for both in-person and telehealth visits for the same patient encounter can trigger claims audits and denials. Always ensure that telehealth and in-person services are correctly differentiated.
- Lack of patient consent documentation: Failing to properly document patient consent for telehealth visits can lead to compliance issues and reimbursement delays. Ensure that verbal consent is noted before every telehealth visit.
- Insufficient proof of time spent during time-based E/M codes: Billing for time-based E/M services without proper time documentation can result in claim denials or repayment requests. Always record and report the time spent on the telehealth service.
How to Prepare for Payer Audits
To ensure audit readiness, practices should:
- Maintain detailed patient documentation for all telehealth services, including the modality used, time spent, and medical necessity.
- Conduct monthly internal coding audits to catch errors early, ensuring that all claims meet CMS and payer-specific guidelines.
- Implement real-time verification systems for POS codes and modifiers to prevent billing mistakes before claims are submitted.
- Train billing staff regularly on CMS and commercial payer updates, especially concerning telehealth, as the guidelines continue to evolve.
- Establish a compliance officer or lead to review high-risk claims and address any potential billing issues proactively. This ensures ongoing vigilance and early identification of potential risks.
Expert Tips for Optimizing Telehealth Billing Processes
