Physical Therapy Billing Updates for 2026: CPT Codes, Medicare Rules & Reimbursement Changes

Are you aware of the latest changes affecting physical therapy billing in 2026? As the healthcare system continues to evolve, billing processes are also becoming more detailed and structured. Even small updates can affect how services are recorded, processed, and reimbursed, making it important for providers to stay informed and prepared.

At the same time, new approaches in care delivery and performance tracking are influencing how therapy services are valued. This means providers need to be more careful and consistent in their billing practices to avoid delays or errors.

In this blog, we will explain the key physical therapy billing updates for 2026, including CPT codes, Medicare rules, and reimbursement changes.

Physical Therapy Billing Updates for 2026: CPT Codes

In 2026, several important updates to CPT codes are shaping how physical therapy services are reported and billed. These changes aim to improve clarity, support remote care services, and align coding with modern treatment practices. Therefore, providers must stay informed to ensure accurate coding and avoid reimbursement issues.

• New RTM Codes

In 2026, new Remote Therapeutic Monitoring codes, including 98979, 98984, and 98985, have been introduced to expand billing for remote care services. These codes support the monitoring of therapy-related activities. As a result, providers can now capture additional services performed outside traditional in-person visits more effectively.

• Revised RTM Descriptors

The existing RTM codes 98976 and 98977 have been updated with descriptors to better define their use. These revisions clarify how device supply and monitoring services should be reported. Consequently, providers must review these changes carefully to ensure correct application and avoid errors in claim submissions.

• “Sometimes Therapy” Classification

There are certain RTM codes that are now categorized as “sometimes therapy,” meaning they may or may not be considered therapy services depending on usage. Therefore, providers must apply appropriate modifiers when billing. This classification helps improve accuracy in distinguishing therapy-related services from other medical services.

• 2026 CPT Code Set Changes

The 2026 CPT code set includes over 400 updates across multiple specialties, including physical therapy. These changes involve revised code descriptors, new additions such as RTM-related services, and updated reporting guidelines. As a result, providers must carefully review these updates to ensure accurate coding, proper documentation, and compliance with current billing standards.

• Updated Therapy Code List

The 2026 Therapy Code List has been revised to clearly define “always therapy” and “sometimes therapy” codes, including the addition of certain RTM services under conditional classification. These updates impact modifier usage, particularly GP, GO, and GN. Therefore, understanding these classifications is essential for correct billing and avoiding claim rejections.

Physical Therapy Billing Updates for 2026: Medicare Rules

Medicare rules for physical therapy billing in 2026 have been updated to improve compliance, expand access to care, and support modern treatment approaches. These changes require providers to adapt their documentation and billing practices. As a result, staying informed is essential for maintaining compliance and ensuring smooth reimbursement processes.

• KX Modifier Threshold Updates

The KX modifier threshold for 2026 has been updated for therapy services, including separate limits for PT, SLP, and OT. Beyond this threshold, providers must justify medical necessity for continued treatment. Therefore, accurate documentation becomes critical to support services and avoid potential claim denials.

• Telehealth Extension

Telehealth flexibilities for therapy services have been extended through 2027, allowing providers to continue offering remote care. This includes virtual visits and certain telephone-based services. As a result, patients can access therapy more conveniently, while providers can maintain continuity of care across different settings.

• Plan of Care Requirements

Medicare continues to require a certified plan of care for therapy services, which must be approved by a physician or qualified provider. Additionally, ongoing documentation of patient progress is necessary. This ensures that services remain medically necessary and aligned with treatment goals throughout the care period.

• MIPS Measure Updates

Updates to MIPS measures for 2026 include changes to musculoskeletal performance metrics, particularly MSK6 to MSK9. These revisions affect reporting requirements and patient eligibility criteria. Consequently, providers must understand these changes to maintain compliance and achieve optimal performance scores.

• Focus on Remote Care Integration

Medicare is increasingly supporting the integration of remote care services into therapy practices. This includes the use of monitoring technologies and digital tools. Therefore, providers are encouraged to adopt these solutions, as they align with broader healthcare trends and improve patient engagement.

Physical Therapy Billing Updates for 2026: Reimbursement Changes

Reimbursement changes in 2026 reflect Medicare’s focus on efficiency, value-based care, and the integration of new service models. These updates directly impact how physical therapy services are paid. Therefore, providers must understand these changes to optimize revenue and maintain financial stability.

• Physician Fee Schedule Updates

The 2026 Physician Fee Schedule includes adjustments to payment rates for therapy services. These changes are influenced by updated conversion factors and policy decisions. As a result, reimbursement amounts may vary, requiring providers to review fee schedules carefully and plan their financial strategies accordingly.

• RTM Reimbursement Policies

Reimbursement for Remote Therapeutic Monitoring services has been expanded to include newly introduced codes. These services are now better recognized within the payment system. Consequently, providers can receive compensation for remote patient monitoring activities, supporting the adoption of technology-driven care models.

• Supervision & “Incident-To” Rules

Clarifications around supervision and “incident-to” billing have been introduced to ensure proper service reporting. Providers must understand when services can be billed under supervision. Therefore, adhering to these rules is important for maintaining compliance and avoiding reimbursement issues.

• Threshold Implications

Therapy spending that exceeds the KX modifier threshold requires proper justification of medical necessity for continued reimbursement. This creates a financial checkpoint for providers. As a result, maintaining accurate and detailed documentation is essential to support ongoing treatment and secure payments.

• Value-Based Payment Impact

Reimbursement is increasingly linked to performance through value-based care models. Providers are evaluated based on quality measures and outcomes. Therefore, improving clinical performance and reporting accuracy can directly influence payment levels and overall financial success.

• Telehealth Reimbursement Alignment

Medicare continues to support reimbursement for telehealth-based therapy services. Payment policies are being aligned to encourage remote care delivery. As a result, providers can integrate telehealth into their practice while maintaining reimbursement, improving accessibility and continuity of care for patients.

Conclusion

Physical therapy billing is undergoing a significant transformation in 2026, as updates to CPT codes, Medicare rules, and reimbursement policies are shaping a more structured, performance-driven environment. Therefore, providers must adopt a more precise and informed billing approach to ensure compliance, maintain accuracy, and support consistent financial outcomes.

Moreover, managing these evolving requirements internally can become increasingly demanding, especially when clinical teams are already handling patient care responsibilities. As a result, maintaining accuracy in coding, proper modifier usage, and timely submissions requires continuous attention, training, and operational efficiency.

Therefore, partnering with outsourcing physical therapy billing and coding service providers, such as 24/7 Medical Billing Services, can offer valuable support. Moreover, their expertise in physical therapy billing and coding helps streamline workflows, reduce errors, and improve overall revenue cycle performance while ensuring compliance with updated regulations. Ultimately, success in adapting to 2026 billing changes depends on a balanced approach that combines knowledge, strategy, and the right support systems.
