Telehealth Billing Guide 2026: Codes, Rules & Denial Prevention

Telehealth billing has never been more valuable, or more confusing. Lawmakers extended the COVID-era flexibilities that temporarily expanded Medicare telehealth coverage through the end of 2026, yet the landscape keeps splitting apart: Medicare, Medicaid, and commercial payers each set their own telehealth coverage rules, place-of-service requirements, and coding standards. As a result, practices that bill telehealth correctly capture a significant revenue stream, while those that bill it incorrectly generate denials, recoupments, and compliance exposure.

This guide gives you a current, practical map of telehealth billing in 2026: what payers cover, how to code it, and exactly how to avoid the denials that are tripping up practices across every specialty.

The Telehealth Billing Landscape in 2026

Medicare Telehealth Coverage

The Consolidated Appropriations Act extended many COVID-era Medicare telehealth flexibilities through December 31, 2026. Here are the key provisions still in effect:

• Patients can receive Medicare telehealth from home; they no longer need to be in a rural area or at a designated originating site.
• Medicare’s list of telehealth-eligible services remains expanded beyond pre-pandemic coverage and now includes behavioral health, remote physiologic monitoring, and many specialist visit types.
• Audio-only (telephone) visits cover behavioral health and some primary care services, though not every service type qualifies.
• Federally Qualified Health Centers (FQHCs) and Rural Health Clinics (RHCs) can serve as distant sites.

Importantly, these extensions are legislative, not permanent. So, if Congress does not act before December 31, 2026, many telehealth provisions will revert to pre-pandemic rules, requiring rural originating sites again and eliminating home-based telehealth for most Medicare patients. For that reason, monitor CMS and Congressional developments closely in Q4 2026.

Medicare Advantage Telehealth

Medicare Advantage plans set their own telehealth coverage rules, and these can be more generous than traditional Medicare. However, more and more MA plans now require prior authorization for telehealth services, even for services that need no authorization under traditional Medicare. Therefore, verify MA plan-specific telehealth auth requirements at the start of each benefit year.

Medicaid Telehealth Coverage

Medicaid telehealth coverage is state-specific and varies dramatically from one state to the next. As of 2026, all 50 states cover some form of telehealth for Medicaid beneficiaries, but the covered service types, place-of-service rules, and reimbursement rates differ significantly by state. Consequently, practices serving Medicaid populations must maintain a state-specific telehealth billing reference and update it every year.

Commercial Payer Telehealth

Most major commercial payers still cover telehealth services at or near in-person rates under benefit mandates enacted during the pandemic. That said, coverage parity laws vary by state, and some payers have begun tightening telehealth requirements for certain service types. So, always verify payer-specific telehealth coverage and reimbursement rates before assuming parity.

Telehealth CPT Codes and Billing Requirements in 2026

Standard Telehealth E/M Visits

Office and outpatient E/M visits delivered via telehealth use the same CPT codes as in-person visits (99202–99215 for new and established patients). What sets them apart is the place-of-service (POS) code and the modifier:

• POS 02 — Telehealth, patient not in their home (use for clinic-to-clinic or facility-to-clinic telehealth)
• POS 10 — Telehealth, patient in their home (the most common POS for 2026 telehealth visits)
• Modifier 95 — Synchronous telemedicine service rendered via real-time interactive audio and video telecommunication system

One critical rule to remember: POS 10 reimburses at the facility rate, which in some contexts is lower than the non-facility rate tied to POS 02. So, know the reimbursement difference before choosing between the two codes.

Audio-Only (Telephone) Visit Codes

Medicare covers telephone-only visits, without video, for behavioral health and some primary care services, using specific audio-only codes:

• 99441 — Telephone evaluation and management, 5–10 minutes
• 99442 — Telephone evaluation and management, 11–20 minutes
• 99443 — Telephone evaluation and management, 21–30 minutes

You cannot bill audio-only visits with the standard E/M codes (99202–99215). In fact, billing an audio-only visit as a synchronous video visit counts as an overcoding error with real compliance implications.

Behavioral Health Telehealth Codes

Behavioral health services delivered via telehealth remain among the most widely covered telehealth service types in 2026:

• 90832–90838 — Individual psychotherapy (30, 45, 60 minutes) with or without E/M
• 90839–90840 — Psychotherapy for crisis
• 90847 — Family psychotherapy with patient present
• 90853 — Group psychotherapy
• 99213–99214 + 90833/90836 — E/M with psychotherapy add-on

Telehealth claims of behavioural health require POS 10 (patient at home) or POS 02 (patient at non-home site) with modifier 95. For audio-only behavioral health, use the telephone E/M codes with modifier 93, where the payer requires it.

Remote Physiologic Monitoring (RPM)

RPM codes (99453, 99454, 99457, 99458) let practices bill for monitoring patients’ physiologic data, such as blood pressure, glucose, and weight, collected by connected devices between in-person visits. In fact, RPM ranks as one of the fastest-growing telehealth revenue streams for primary care and chronic disease management practices:

• 99453 — Device setup and patient education (billed once per episode)
• 99454 — Device supply with daily recording/programming (billed monthly, requires 16+ days of data transmission)
• 99457 — Remote physiologic monitoring treatment management, first 20 minutes per month
• 99458 — Each additional 20 minutes per month (add-on to 99457)

RPM billing requires documented patient consent, a physician order, and at least 16 days of data transmission per month for 99454. Billing 99454 for months with fewer than 16 transmission days is a common compliance error.

The 7 Most Common Telehealth Billing Denials in 2026

1. Wrong Place-of-Service Code

Using POS 02 instead of POS 10, or vice versa, causes the most frequent telehealth billing error. Use POS 10 when the patient is in their home, which describes most 2026 telehealth visits, and use POS 02 when the patient is at a non-home location. For some payers, reimbursement rates and coverage rules differ between these two codes, so getting this wrong carries real financial consequences.

2. Missing Modifier 95 or 93

Payers often process telehealth claims that lack the required modifier as in-person visits, then deny them once the place-of-service code fails to match the in-person rate structure. So, always attach modifier 95 to synchronous audio-video visits and modifier 93 to audio-only visits where required.

3. Billing Audio-Only Visits With In-Person E/M Codes

You cannot bill a telephone visit as a 99213 or 99214. These codes require a face-to-face encounter, which video telehealth satisfies but audio-only does not. Instead, audio-only visits must use the telephone codes (99441–99443) or the behavioral health audio-only codes.

4. Telehealth Prior Authorization Failures

Increasingly, commercial payers and Medicare Advantage plans require prior authorization for telehealth services, sometimes separately from the in-person auth for the same service. If you fail to verify telehealth-specific auth requirements before the visit, you’ll get a technical denial even when the clinical service itself is covered.

5. Technology Non-Compliance

Medicare and most commercial payers require telehealth visits to run on a real-time, interactive audio and video system. Consumer-grade platforms, such as standard phone calls or some SMS-based tools, that fail to meet HIPAA and payer technology standards can trigger claim denials for “non-compliant technology.” So, verify that your telehealth platform appears on the payer’s approved technology list.

6. Consent Documentation Gaps

Many states require documented patient consent for telehealth services, and for RPM, Medicare requires that consent before the service begins. Missing or undated consent documentation shows up frequently as an audit finding, and it can invalidate previously paid claims in retrospect.

7. Billing for Services Outside the Covered Telehealth Service List

Not every CPT code qualifies for telehealth reimbursement. CMS publishes an annual list of Medicare-covered telehealth services, and billing a procedure or visit type that falls outside that list with POS 10 or 02 will result in a denial. So, maintain a current telehealth-eligible service list and cross-reference it against your billed codes every quarter.

Building a Compliant Telehealth Billing Workflow

• Maintain a payer-by-payer telehealth coverage matrix, and update it every year. Telehealth rules change each January, so what was covered last year may not be covered this year, and vice versa.
• Document the technology used for every telehealth visit in the medical record, including the platform name, the session type (audio-video or audio-only), and confirmation of patient consent.
• Train clinical staff on telehealth documentation requirements, particularly how to document the synchronous, interactive nature of the visit along with any clinical findings that differ from what an in-person encounter would capture.
• Conduct a quarterly telehealth claim audit, reviewing 20–30 telehealth claims for POS accuracy, modifier use, covered service type, and documentation completeness.
