Telehealth therapy billing uses the same CPT procedure codes as in-person therapy, but requires specific Place of Service codes and sometimes modifiers. Getting these right determines whether your claims — or your clients' superbill submissions — are paid.
CPT Codes for Telehealth: Same as In-Person
There are no separate CPT codes for telehealth psychotherapy. You bill the same codes based on session length:
- 90832 — 30-minute individual therapy
- 90834 — 45-minute individual therapy
- 90837 — 60-minute individual therapy
- 90847 — Family therapy with patient present
The telehealth distinction is captured in the Place of Service code and, in some cases, a billing modifier — not the CPT code itself.
Place of Service (POS) Codes for Telehealth
- POS 10 — Telehealth Provided in Patient's Home. Use when the client is at home during the session (audio + video). This is the standard post-pandemic telehealth POS code and should be used for most private practice telehealth sessions.
- POS 02 — Telehealth Provided Other than in Patient's Home. Use when the client is at a clinic, office, or other non-home location and the provider is remote.
- POS 11 — Office. Use for in-person sessions only. Do not use POS 11 for telehealth; some payers will deny or flag the claim.
The GT Modifier
The GT modifier ("via interactive audio and video telehealth systems") is required by Medicare and some private payers. Append it to the CPT code when the payer requires it: for example, 90837-GT.
Since 2022, Medicare has largely built telehealth recognition into POS 10 and POS 02, so GT is less universally required than it was during the early pandemic period. Check your specific payer's current telehealth billing guide — requirements vary.
Audio-Only vs Audio-Video
Standard telehealth CPT codes assume two-way audio-video (synchronous). Audio-only sessions (phone calls) have more complex coverage:
- Medicare covers audio-only therapy with modifier 93 (through active policy extensions)
- Many private payers do not reimburse audio-only therapy
- State telehealth parity laws may require coverage, but vary significantly
When in doubt, use video for sessions you intend to bill or include on a superbill.
State Telehealth Parity Laws
Most U.S. states have telehealth parity laws requiring insurers to reimburse covered telehealth services at the same rate as in-person services. However, parity law strength varies — some states cover only services with a prior in-person relationship; others require full parity for any licensed provider. Check your state's insurance department resources for current rules.
Telehealth on a Superbill
A superbill for a telehealth session should note:
- CPT code (e.g., 90837)
- Place of Service code (10 for patient at home)
- Modifier if required by the payer (GT)
- ICD-10 diagnosis code
- Date and fee
Superbilled includes a Place of Service field in every superbill, making it easy to correctly note telehealth sessions before generating the PDF.
