Telehealth Billing in 2026: CPT Codes, Payer Rules & Reimbursement Guide

Published April 20, 2026 · 13 min read · By RCMAXIS Revenue Cycle Team

Telehealth has permanently reshaped how care is delivered in the United States. Since the COVID-19 public health emergency, Congress has repeatedly extended telehealth flexibilities, and the 2026 landscape reflects a hybrid model where virtual visits are now a standard — not a temporary — component of medical practice.

Yet telehealth billing remains one of the most denial-prone areas in revenue cycle management. Incorrect place of service codes, wrong modifiers, missing originating site documentation, and payer-specific rules create a complex billing landscape. This guide gives you the exact framework to bill telehealth correctly and maximize reimbursement.

Key Telehealth Billing Terms You Must Know

• Originating site — where the patient is located during the telehealth encounter
• Distant site — where the provider is located (your clinic)
• Synchronous telehealth — real-time audio/video communication (most E&M visits)
• Asynchronous telehealth — store-and-forward; patient submits data reviewed later (e.g., teledermatology)
• Audio-only — telephone-only visits; different rules apply than video visits

Place of Service Codes for Telehealth in 2026

Getting the place of service (POS) code wrong is the number one telehealth billing error. Here is what to use:

Critical rule: CMS introduced POS 10 in 2022 specifically for home-based telehealth. Using POS 02 when the patient is at home results in lower reimbursement (facility rate instead of non-facility rate). Most patient telehealth visits should be billed with POS 10.

Telehealth Modifiers: GT vs 95 vs 93

Practical tip: For Medicare in 2026, use modifier 95 for video visits with POS 10. Modifier GT is still accepted but 95 is now the preferred standard. Always verify individual payer requirements — Medicaid and commercial plans vary significantly.

Most Common Telehealth CPT Codes in 2026

Office / Outpatient E&M — New Patients (99202–99205)

• 99202 — straightforward MDM, 15–29 minutes
• 99203 — low MDM, 30–44 minutes
• 99204 — moderate MDM, 45–59 minutes
• 99205 — high MDM, 60–74 minutes

Office / Outpatient E&M — Established Patients (99211–99215)

• 99212 — straightforward MDM, 10–19 minutes
• 99213 — low MDM, 20–29 minutes
• 99214 — moderate MDM, 30–39 minutes
• 99215 — high MDM, 40–54 minutes

Behavioral Health Telehealth Codes (High Volume)

• 90837 — Psychotherapy, 60 minutes (most commonly billed telehealth code in mental health practices)
• 90834 — Psychotherapy, 45 minutes
• 90832 — Psychotherapy, 30 minutes
• 90791 — Psychiatric diagnostic evaluation (initial)
• 90792 — Psychiatric diagnostic evaluation with medical services
• 99213 + 90833 — E&M with psychotherapy add-on (common for psychiatry)

Telephone-Only (Audio) Codes

• 99441 — Telephone E&M, 5–10 minutes
• 99442 — Telephone E&M, 11–20 minutes
• 99443 — Telephone E&M, 21–30 minutes

Note: Audio-only codes require Modifier 93 appended. Medicare covers these codes permanently through 2026. Commercial payer coverage varies.

Medicare Telehealth Rules for 2026

Congress extended most COVID-era telehealth flexibilities through December 31, 2026 via the Consolidated Appropriations Act. Key Medicare rules currently in effect:

• Patients can be located anywhere — including their home — for most telehealth services (no rural originating site restriction until 2027)
• New patients can be seen via telehealth (this was temporarily prohibited pre-pandemic)
• Mental health services can be provided via telehealth with an in-person visit required within 12 months of initiation and annually thereafter (as of 2024)
• Providers can furnish telehealth from their home without enrolling their home address as a practice location
• Federally Qualified Health Centers (FQHCs) and Rural Health Clinics (RHCs) can serve as distant sites

Commercial Payer Telehealth Rules: What You Need to Check

Commercial payers each have their own telehealth policies. Before billing any commercial payer for telehealth, verify:

• Which CPT codes are covered for telehealth (not all E&M codes are covered by all plans)
• Modifier requirement — 95, GT, or payer-specific modifier
• Reimbursement parity — 43 states now have laws requiring payment parity (equal pay for telehealth vs in-person), but enforcement varies
• Audio-only coverage — commercial coverage for audio-only remains inconsistent; verify each plan
• Documentation requirements — some payers require specific language in the note confirming patient consent for telehealth
• Platform requirements — a few payers specify HIPAA-compliant platforms only; confirm your platform qualifies

Documentation Requirements for Telehealth

Telehealth notes must include everything required for an in-person visit, plus:

• Confirmation that the visit was conducted via telehealth (audio/video or audio-only)
• Patient's location at the time of service (city and state at minimum)
• Provider's location at the time of service
• Patient verbal consent for telehealth services (document in the note)
• Platform used (e.g., "visit conducted via Zoom for Healthcare, a HIPAA-compliant platform")
• Time-based documentation if billing by time rather than MDM

Top 5 Telehealth Billing Errors and How to Fix Them

1. Wrong POS code (using POS 11 for telehealth) — creates immediate denial. Fix: build a check in your PM system that flags E&M claims with telehealth documentation but POS 11
2. Using POS 02 when patient is at home — results in underpayment (facility vs non-facility rate). Fix: update scheduling templates so patient location is captured and mapped to correct POS
3. Missing modifier on telehealth claim — payer-specific rules; modifier omission causes denial. Fix: build claim edit to require modifier when POS 02 or 10 is used
4. Billing audio-only visit as video visit — this is fraud risk territory. Fix: document platform type in every note; audit quarterly
5. Not verifying telehealth payer coverage before the visit — results in non-covered service denial. Fix: eligibility checks must include telehealth benefit verification, not just active coverage
