The Complete Guide to Telehealth Billing in 2025: Codes, Modifiers, and Payer Policies
Telehealth has transformed from an emergency measure during the pandemic to a permanent fixture of healthcare delivery. Yet telehealth billing remains one of the most challenging areas for medical practices, with constant policy changes, varying payer requirements, and new coding structures. This comprehensive guide will help you navigate the complexities of telehealth billing and maximize reimbursement for virtual care services.
The Evolution of Telehealth Billing
Understanding where telehealth billing has been helps contextualize where it is today. Before 2020, telehealth billing was limited to specific geographic areas and facility types. Medicare restricted telehealth to patients in designated rural health professional shortage areas, and the patient had to be at an eligible originating site like a hospital or clinic. Commercial payers varied widely in their telehealth coverage. The COVID-19 public health emergency changed everything. CMS implemented sweeping waivers that allowed telehealth from anywhere, including patients’ homes. Commercial payers followed with similar expansions. Suddenly, practices across the country were delivering and billing for virtual care. As the public health emergency winds down, we are entering a new phase of telehealth billing that retains many pandemic-era flexibilities while introducing new complexity. Understanding the current landscape is essential for practices that have incorporated telehealth into their care delivery models.Understanding the New Telehealth CPT Codes
The most significant development in telehealth billing is the introduction of CPT codes 98000-98016, specifically designed for synchronous audio-video telehealth encounters. These codes represent a fundamental shift from the modifier-based approach that characterized telehealth billing during the pandemic. The new telehealth code set mirrors the structure of traditional office visit codes. Codes 98000-98004 are for new patients, while codes 98010-98016 are for established patients. Like traditional E/M codes, level selection is based on either medical decision-making complexity or total time.New Patient Codes
Code 98000 is a basic new patient telehealth visit with straightforward medical decision-making or 15-29 minutes. Code 98001 is a new patient visit with low complexity decision-making or 30-44 minutes. Code 98002 involves moderate complexity or 45-59 minutes. Code 98003 requires high complexity decision-making or 60-74 minutes. Code 98004 is for prolonged services of 75 minutes or more.Established Patient Codes
The established patient codes follow a similar structure. Code 98010 is for straightforward visits or 10-19 minutes. Code 98011 involves low complexity or 20-29 minutes. Code 98012 requires moderate complexity or 30-39 minutes. Code 98013 involves high complexity or 40-54 minutes. Code 98016 is for prolonged established patient services of 55 minutes or more. Documentation requirements for these codes parallel traditional E/M requirements but with telehealth-specific elements, including platform used, patient consent, locations, and all elements required for the level of service billed.Medicare and Commercial Payer Considerations
Despite the introduction of the new telehealth codes, Medicare has not adopted them. For Medicare patients, practices should continue using traditional office visit codes (99202-99215) with appropriate telehealth modifiers. This creates a dual-track billing system that requires careful attention. Use modifier 95 for synchronous audio-video telehealth. Place of service should be 10 (telehealth at patient’s home) or 02 (telehealth at other locations). Audio-only visits require modifier 93 for eligible services.Commercial payers are adopting new codes at different rates, creating a complex patchwork. Some payers have full adoption, others maintain modifier-based systems, and some implement hybrids. Each payer’s requirements must be verified for accepted codes, modifiers, POS, audio-only coverage, visit limits, prior authorization, and reimbursement rates. Maintaining a payer-specific telehealth policy matrix is essential.Remote Patient Monitoring and Chronic Care Management
Beyond synchronous visits, practices can bill for RPM and CCM. Remote Patient Monitoring codes include:- CPT 99453 for initial setup and patient education
- CPT 99454 for device supply with daily recordings
- CPT 99457 for first 20 minutes of RPM treatment management
- CPT 99458 for each additional 20 minutes
- CPT 99490 for first 20 minutes of clinical staff time
- CPT 99439 for each additional 20 minutes
- CPT 99491 for first 30 minutes of physician time
- CPT 99437 for each additional 30 minutes
Multi-State Licensure and Documentation Best Practices
Telehealth enables multi-state care but creates licensure complexity. Providers must be licensed where the patient is located. Interstate Medical Licensure Compact (40+ states) and Nurse Licensure Compact simplify multi-state practice. Some states require full licenses or special telehealth registration. Verify prescribing rules, informed consent, malpractice coverage, and corporate practice laws.Documentation should include technology verification, patient identification, locations, consent, clinical documentation, and any technical issues resolved. Use telehealth-specific templates to ensure all required elements are captured.Common Telehealth Billing Errors
- Incorrect place of service codes
- Missing or incorrect modifiers
- Billing audio-only as video
- Services not eligible for telehealth
