Telehealth Billing 2026: CPT Codes, Place of Service & Payer Rules
Telehealth billing is one of the most rule-dense areas in revenue cycle management. The codes, modifiers, and place-of-service requirements differ by visit type, patient location, provider type, and payer. What Medicare allows may be restricted by a commercial plan. What worked under the COVID public health emergency may require new documentation under 2026 rules. This guide cuts through the confusion and gives your billing team a clear framework for every type of virtual visit.
The Telehealth Billing Framework: 4 Visit Types
Before assigning a CPT code, determine which of the four telehealth delivery models applies:
- Synchronous audio-video — real-time two-way video; the standard for most telehealth E&M visits
- Audio-only — telephone without video; restricted to specific scenarios under Medicare and many commercial plans
- Asynchronous (store-and-forward) — patient submits photos, data, or messages; provider reviews and responds later
- Remote patient monitoring (RPM) — continuous or periodic physiologic data collected via devices and reviewed by the clinical team
Each model has its own CPT codes, documentation requirements, and payer-specific authorization rules.
Place of Service Codes: Getting POS Right
The single most common telehealth denial cause is an incorrect place-of-service (POS) code. Medicare and most commercial payers require specific POS codes to identify where the patient was located during the visit — not where the provider was.
| POS Code | Description | When to Use |
|---|---|---|
| 02 | Telehealth — Not Home | Patient is at a clinic, hospital, or other facility during the visit |
| 10 | Telehealth — Patient Home | Patient is at their personal residence; most common for 2026 |
| 11 | Office | Provider is in office delivering asynchronous services; patient location not relevant |
| 02 + GT | Legacy Medicare (pre-2025) | Now largely replaced by POS 02/10 — confirm payer policy |
Synchronous Audio-Video E&M Codes
Standard office visit codes (99202–99215) apply to audio-video telehealth when the visit meets the same documentation thresholds as an in-person E&M. The 2021 E&M guidelines (medical decision-making or total time) apply equally to telehealth.
| CPT Code | Visit Level | MDM Complexity | Total Time (2026) |
|---|---|---|---|
| 99202 | New Patient — Low | Straightforward | 15–29 min |
| 99203 | New Patient — Low | Low | 30–44 min |
| 99204 | New Patient — Moderate | Moderate | 45–59 min |
| 99205 | New Patient — High | High | 60–74 min |
| 99211 | Established — Minimal | N/A | Staff visit, no physician required |
| 99212 | Established — Low | Straightforward | 10–19 min |
| 99213 | Established — Low | Low | 20–29 min |
| 99214 | Established — Moderate | Moderate | 30–39 min |
| 99215 | Established — High | High | 40–54 min |
Required Modifiers for Telehealth E&M
- Modifier 95 — synchronous telemedicine service rendered via real-time interactive audio-video communication; required by most commercial payers
- Modifier GT — via interactive audio and video telecommunications systems; still required by some Medicare Advantage and commercial plans — verify payer by payer
- Modifier GQ — via asynchronous telecommunications systems; used for store-and-forward services in approved states
- Modifier 93 — synchronous telemedicine service rendered via telephone or other real-time interactive audio-only communications; used for audio-only visits under specific Medicare rules
Audio-Only Telehealth Billing
Audio-only (telephone-only) visits without video remain permanently covered by Medicare for established patients under certain conditions. They're not covered as standard E&M codes — use the telephone E&M series instead.
| CPT Code | Time | Who Uses It | Notes |
|---|---|---|---|
| 99441 | 5–10 min | Physician/NPP | Telephone E&M, established patient |
| 99442 | 11–20 min | Physician/NPP | Telephone E&M, established patient |
| 99443 | 21–30 min | Physician/NPP | Telephone E&M, established patient |
| 98966 | 5–10 min | Non-physician (LPC, SW) | Telephone assessment by qualified professional |
| 98967 | 11–20 min | Non-physician | Telephone assessment by qualified professional |
| 98968 | 21–30 min | Non-physician | Telephone assessment by qualified professional |
Key restriction: audio-only codes can't be billed if the call originated as a follow-up to an E&M visit within the previous 7 days or leads to an in-person visit within 24 hours. Document that the patient was offered video and declined if using audio-only — several payers require this attestation.
Asynchronous & Check-In Codes
Not every patient interaction requires a synchronous visit. Medicare and many commercial payers cover shorter asynchronous communications when documented properly.
| CPT / HCPCS | Service | Time / Notes |
|---|---|---|
| G2012 | Brief communication check-in | 5–10 min; patient-initiated; can't be within 7 days of related E&M |
| G2010 | Remote evaluation of images/video | Patient-submitted; provider reviews asynchronously; 5–10 min |
| 99421 | Online digital E&M — Low | 5–10 min cumulative in 7 days; patient portal or secure messaging |
| 99422 | Online digital E&M — Moderate | 11–20 min cumulative in 7 days |
| 99423 | Online digital E&M — High | 21+ min cumulative in 7 days |
Medicare vs. Commercial Payer Telehealth Rules
The gap between Medicare's telehealth coverage and commercial plan policies is one of the biggest sources of billing confusion in 2026.
Medicare (Traditional)
- Covers synchronous audio-video E&M (99202–99215) permanently for mental health, substance use disorder, and several other conditions
- Requires POS 02 or 10 — no GT modifier required as of 2024 forward for most services
- Audio-only (99441–99443) covered for established patients; patient must lack access to video
- Originating site (where patient is located) no longer required to be a healthcare facility for most services
- Rural geographic restriction has been waived permanently for mental health telehealth
Medicare Advantage Plans
- May require modifier GT or 95 — always verify each MA plan's telehealth addendum
- Some MA plans restrict telehealth to in-network providers only, even if the service is covered
- Prior authorization requirements vary widely — some MA plans require PA for video visits above 99213
Commercial / Private Payers
- State parity laws require most commercial plans to reimburse telehealth at the same rate as in-person visits in 43 states as of 2026
- Most require modifier 95 on the claim; some still require GT
- Audio-only coverage varies significantly — many plans exclude 99441–99443 or limit to behavioral health
- Platform requirements: some plans restrict coverage to specific telehealth platforms (Teladoc, MDLive, etc.) for certain services
Telehealth Billing for Behavioral Health
Mental health and substance use disorder services have the most favorable telehealth coverage rules across all payer types. Key considerations:
- Medicare: Psychotherapy codes (90832–90838) are permanently covered via telehealth; no geographic or originating site restriction
- Initial mental health visits: May now be conducted via telehealth for Medicare patients (in-person requirement removed permanently)
- Substance use disorder: 99408, 99409, and SBIRT services covered via telehealth under Medicare
- Concurrent billing: Psychotherapy add-on codes (90833, 90836, 90838) can be billed with E&M codes during the same telehealth session with modifier 25 on the E&M
Remote Patient Monitoring (RPM) — A Growing Revenue Stream
RPM allows practices to bill for ongoing monitoring of patients between visits. It's one of the fastest-growing telehealth billing categories and applies to chronic disease management, post-surgical monitoring, and preventive care programs.
| CPT Code | Service | Billing Notes |
|---|---|---|
| 99453 | RPM — Initial setup & patient education | One-time per device; ≥16 days monitoring required in first 30 days to bill 99454 |
| 99454 | RPM — Device supply & daily transmission | Per 30-day period; device must transmit data ≥16 days/month |
| 99457 | RPM — First 20 min staff time/month | Requires interactive communication with patient during the period |
| 99458 | RPM — Each additional 20 min | Add-on to 99457; document time carefully |
RPM requires a written care plan, informed patient consent, and documentation that the device transmits data automatically (not patient-manually-entered data, which falls under RTM codes instead). The 16-day transmission threshold is a hard line — practices that bill 99454 without confirming the transmission count face high-volume denials.
Top Telehealth Denial Reasons & Fixes
| Denial Reason | Root Cause | Fix |
|---|---|---|
| Service not covered via telehealth | CPT code not on payer's telehealth list | Verify payer's covered telehealth service list before visit; obtain prior auth for borderline codes |
| Missing/wrong modifier | 95 vs GT confusion, or modifier absent | Set telehealth modifier by payer in your billing system as a default rule |
| Wrong POS code | POS 11 used instead of POS 10 | Build a workflow prompt asking where the patient was located at time of visit |
| Audio-only not covered | Plan excludes telephone E&M | Verify coverage before the call; document patient's inability to use video if claiming exception |
| New patient restriction | Payer requires in-person for new patients | Screen new patient telehealth eligibility at scheduling; flag first visits for manual review |
| RPM 99454 — insufficient transmission days | Device transmitted fewer than 16 days | Track device transmission counts in EHR before billing cycle; don't batch-bill RPM at month end without verifying |
| Duplicate of in-person visit same day | G2012 or 99421 billed on same day as E&M | Asynchronous check-in codes can't be billed on same day as E&M for same condition |
Documentation Requirements for Telehealth Visits
The clinical note for a telehealth visit must include elements that in-person notes don't require:
- Statement confirming the visit was conducted via synchronous audio-video (or audio-only if applicable)
- Patient's location at the time of the visit (city and state at minimum)
- Provider's location at the time of the visit
- Patient's verbal consent to telehealth visit (for first telehealth encounter and annually)
- For audio-only: statement that patient was offered video and declined, or lacks technology access
- All standard E&M documentation: chief complaint, history, assessment, plan, time if billing by time
