Direct Answer
Telehealth billing has undergone the most significant transformation of any area in medical billing since the COVID-19 pandemic. Temporary waivers that expanded Medicare telehealth coverage — removing geographic and originating site restrictions, permitting audio-only services, allowing home visits to be covered — have been extended through legislation multiple times. The core billing elements for a telehealth-only practice are: the correct place of service code (POS 02 for telehealth when the patient is not at home; POS 10 for telehealth to the patient's home), the telehealth modifier (GT for Medicare or 95 for commercial), and documentation that the service met the applicable technology standard (interactive audio-video vs. audio-only). Getting these elements wrong results in systematic claim denials.

POS 02 vs POS 10
The place of service code on a telehealth claim tells the payer where the patient was located during the telehealth encounter — this directly affects reimbursement rates: POS 02 — Telehealth provided other than in patient's home: used when the patient receives telehealth services at a location other than their home: a telehealth originating site (clinic, hospital, FQHC, rural health clinic); a facility or office where the patient presents to receive the telehealth service; note: POS 02 does not mean the provider's location — it means the patient's location; reimbursement at POS 02: CMS reimburses telehealth E&M at the non-facility rate (same as in-person office visit); for many specialties this is a higher rate than the facility rate; POS 10 — Telehealth provided in patient's home: used when the patient is at home (or in their temporary residence) during the telehealth encounter; this is the most common POS for telehealth-only practices; reimbursement at POS 10: CMS originally reimbursed POS 10 telehealth at the facility rate (lower than non-facility); beginning January 1, 2024, CMS reimburses telehealth E&M at the non-facility rate for both POS 02 and POS 10 — equalizing reimbursement regardless of patient location; this rate equalization significantly improved the economics of telehealth-only practices; Why POS accuracy matters: billing the wrong POS can result in: claim denial (payer's system may not recognize the combination of CPT code + POS code); incorrect rate application; audit findings identifying systematic POS errors as a billing compliance issue; Provider location vs. patient location: the place of service on the claim reflects the patient's location, not the provider's; a telehealth-only provider working from their home office still uses POS 10 (patient's home) when the patient is at home; the provider's location is captured differently (rendering provider's address on the claim) but does not drive the POS code selection.
GT Modifier, Modifier 95, and Audio-Only
Telehealth modifiers indicate the technology used and the nature of the telehealth service: GT Modifier — Medicare telehealth: Modifier GT indicates that the service was provided via interactive audio and video telecommunications system; Medicare requires GT on telehealth claims submitted with POS 02 or POS 10 to indicate that the service meets Medicare's interactive real-time communication standard; GT certifies that the service was delivered via a two-way, real-time interactive communication system with both audio and video; Modifier 95 — commercial telehealth: Modifier 95 is the standard telehealth modifier used for commercial payers (non-Medicare); indicates the service was rendered via synchronous real-time interactive audio and video telecommunications system; widely used by commercial payers as the telehealth billing standard; many payers accept either GT or 95 — verify by payer contract; Audio-only telehealth billing: during the COVID-19 public health emergency, CMS temporarily allowed audio-only telephone E&M services to be billed on the Medicare telehealth list; specific CPT codes for telephone E&M: 99441 (telephone medical discussion, 5–10 minutes); 99442 (11–20 minutes); 99443 (21–30 minutes); Modifier 93 (synchronous telemedicine service rendered via telephone or other real-time interactive audio-only telecommunications system): Modifier 93 was created to identify audio-only telehealth when video is not available; post-PHE audio-only coverage: coverage for audio-only telehealth has varied by payer and legislative period; currently, Medicare covers audio-only telehealth for mental health services when the patient is unable or unwilling to use video; FQ Medicare (FQHC) and RHC patients have additional audio-only provisions; Asynchronous vs. synchronous telehealth: synchronous: real-time interactive communication (the standard for billing E&M codes); asynchronous (store-and-forward): recorded images, data, or messages transmitted to a provider for later review; covered by some Medicaid programs and in specific federal programs (Alaska/Hawaii telemedicine demos); generally not billable as an E&M telehealth visit under Medicare.
Medicare Telehealth Coverage Rules
Medicare's telehealth coverage rules have evolved significantly and continue to change with each legislative cycle: Pre-COVID Medicare telehealth restrictions (pre-2020): geographic restriction: only patients in rural Health Professional Shortage Areas (HPSAs) or non-Metropolitan Statistical Areas (non-MSAs) could receive Medicare telehealth; originating site requirement: the patient had to be at a qualified originating site (physician office, hospital, critical access hospital, rural health clinic, FQHC, SNF) — not at home; COVID-19 PHE waivers (2020–2023): CMS waived the geographic restriction — any patient location nationwide; waived the originating site restriction — patient could be at home; expanded the list of covered telehealth services; allowed audio-only services; allowed new patient visits via telehealth; Post-PHE legislative extensions: Congress has repeatedly extended key telehealth waivers through appropriations legislation; as of 2026, key extensions include: geographic restriction waiver extended; patient home as originating site extended; mental health telehealth: added to permanent statute with some requirements (in-person visit within 6 months, except for FQHCs/RHCs); Medicare telehealth-eligible services list: CMS maintains a list of Medicare telehealth services eligible for payment; the list is updated annually through the Physician Fee Schedule rulemaking; the list now includes hundreds of codes across specialties; not all CPT codes are on the list — verify before billing; Ryan Haight Act and DEA prescribing: the DEA's Ryan Haight Act normally requires an in-person evaluation before prescribing controlled substances via telehealth; PHE waivers suspended this requirement; as waivers expire, the DEA has implemented a special registration process for telehealth prescribers of controlled substances; this particularly affects psychiatry and pain management telehealth practices.
Commercial Payer Telehealth Billing
Commercial payer telehealth coverage is generally broader than Medicare but varies significantly by plan: State telehealth parity laws: most states now have telehealth parity laws requiring commercial insurers to: cover telehealth services that would be covered if provided in-person; reimburse telehealth services at the same rate as in-person services (payment parity — not all states require this); accept telehealth claims on the same claim form as in-person claims; parity laws apply to fully-insured commercial plans regulated by the state insurance commissioner; self-insured employer plans (governed by ERISA) are exempt from state insurance regulations including parity laws; Commercial telehealth billing mechanics: verify each payer's telehealth billing requirements: required modifier (95, GT, or none); acceptable platforms (some payers require specific HIPAA-compliant platforms); covered CPT codes (payers may limit covered telehealth codes); visit type restrictions (new vs. established patient); platform requirements: HIPAA-compliant video platform is required; consumer-grade tools (FaceTime, Zoom free) are not HIPAA-compliant; approved platforms: Doxy.me, Teladoc, MDLive platform, Zoom for Healthcare, Doximity Telehealth; Medicaid telehealth: each state Medicaid program has its own telehealth coverage and billing rules; some states have adopted permanent telehealth expansion; others have revert rules; Medicaid telehealth billing uses GT or 95 modifier per state-specific guidance; billing with incorrect modifier for the state Medicaid program results in systematic denials; Telehealth-only practice contract considerations: telehealth-only practices must: be licensed in every state where patients receive services (provider location rules apply); meet credentialing requirements for each payer in each state; telehealth-only network participation: many commercial networks have specific telehealth provider credentialing pathways.
Telehealth-Only Practice RCM
Telehealth-only practices have unique revenue cycle requirements driven by their virtual delivery model: Licensure and credentialing across multiple states: telehealth-only practices often serve patients in multiple states; each state requires separate medical licensure; the Interstate Medical Licensure Compact (IMLC) accelerates multi-state licensure for eligible physicians; credentialing with each payer in each state is required before billing; maintaining a multi-state licensure and credentialing tracker is essential; Technology platform and billing system integration: the telehealth platform should integrate with the EHR/PMS; visit documentation must flow directly to the billing system; avoiding manual data entry between the telehealth platform and the billing system reduces charge lag and entry errors; Patient identification and consent: telehealth-only practices must: verify patient identity at the start of each telehealth visit (state of patient location determines applicable telehealth laws); obtain and document telehealth consent (many states require explicit telehealth consent); document the patient's location (city and state) at the start of each visit — this determines POS code and licensure compliance; Prescription compliance: electronic prescribing is required for controlled substances under federal law; state-by-state controlled substance prescribing authority for telehealth practitioners is complex; maintain a prescribing authority matrix by state; No-show and late cancellation billing: telehealth no-shows are billable under certain conditions; some practices charge a no-show fee for missed telehealth appointments (charged to the patient, not billed to insurance); document the attempted connection and duration before marking as no-show; Telehealth claim denial patterns: wrong POS code (POS 11 used instead of POS 10); missing telehealth modifier; service not on payer's telehealth-covered code list; provider not licensed in patient's state; platform does not meet payer's technology requirements; new patient telehealth when payer requires established relationship; Collections and patient pay in telehealth: telehealth-only practices often collect payment at the time of service via credit card; pre-authorization of the patient's card before the visit reduces post-visit collections burden; direct-to-consumer telehealth practices (cash-pay or subscription models) bypass insurance billing entirely — different revenue model but no insurance collection risk.
FAQ
What are the billing requirements for a telehealth-only psychiatric practice serving Medicare patients?
Telehealth mental health services for Medicare have specific statutory requirements added by the Consolidated Appropriations Act of 2023 and subsequent legislation: Medicare mental health telehealth requirements: in-person visit requirement: Medicare now requires that mental health telehealth patients have an in-person visit with the telehealth provider (or a member of the same group practice) within 6 months before the initial telehealth mental health service, and annually thereafter; exception: patients of FQHCs and RHCs are exempt from the in-person requirement; exception: audio-only telehealth for patients who are not capable of or do not have access to video; billing the required in-person visit: the in-person visit is billed as a standard office visit (POS 11) with an E&M code; it does not require a specific code but must be documented; subsequent telehealth visits: after the initial in-person visit and annually, all subsequent mental health visits may be conducted via telehealth; billing modifiers for Medicare mental health telehealth: POS 10 (patient at home) + GT modifier for video visits; audio-only: POS 10 + Modifier 93; Prescribing controlled substances in telehealth psychiatry: psychiatric practices prescribing Schedule II–V controlled substances via telehealth must comply with DEA regulations; DEA has created a Special Registration for Telemedicine (SRT) pathway for providers who primarily prescribe via telehealth; until SRT rules are fully implemented, prescribing controlled substances without a prior in-person evaluation may require compliance with specific state and federal requirements; practical implications for billing: telehealth-only psychiatric practices must: schedule and document an annual in-person visit per Medicare patient; maintain a tracking system for the in-person visit dates by patient; ensure the telehealth platform used meets Medicare's interactive audio-video standards; if only audio is available for a session, document the reason and bill with Modifier 93 if audio-only is covered for that service; document patient consent for telehealth services in the medical record.
How should a direct-to-consumer telehealth company bill insurance when some patients are insured and others pay cash?
Direct-to-consumer (DTC) telehealth companies serve a mixed patient population — some insured through their employer or marketplace, some Medicare/Medicaid, some self-pay — requiring a hybrid billing model: Deciding whether to bill insurance: DTC telehealth companies can choose to: participate in insurance networks and bill for all insured patients; operate as out-of-network providers (balance-bill patients up to any OON benefit); operate as a pure cash-pay/subscription model and not bill insurance at all; hybrid: accept some insurers and use cash-pay for others or for non-covered services; Network participation decision factors: benefits of network participation: access to insured patients who expect in-network coverage; lower patient cost-sharing encouraging utilization; revenue from insured patients who cannot or will not pay cash; challenges of network participation: credentialing in every state where patients receive services; compliance with network fee schedules (may be lower than cash prices); prior authorization requirements for some services; billing infrastructure and accounts receivable management; Cash-pay and subscription billing for non-insured patients: membership/subscription models (monthly fee for unlimited visits) are popular for DTC telehealth; these bypass insurance entirely; HIPAA applies regardless of payment model (if any PHI is maintained); subscription model compliance: if the practice also bills insurance for other patients, the subscription pricing must not be structured as a kickback or as a discount given to induce referrals; for patients who are insured, waiving cost-sharing in exchange for a subscription fee can implicate anti-kickback concerns; Good Faith Estimate requirements for self-pay DTC telehealth: the No Surprises Act requires providers to give Good Faith Estimates to uninsured/self-pay patients upon scheduling; for DTC telehealth with a standard pricing model, this can be automated as part of the booking flow; Billing self-pay telehealth visits: for patients without insurance who pay out-of-pocket, bill the full charge at the time of service (credit card, subscription); no claim submission is required; maintain a simplified visit documentation workflow for cash-pay visits.
