Telehealth Coding in 2026: What Survived the PHE Cliff

The PHE telehealth flexibilities that allowed expansive Medicare telehealth coverage during 2020-2023 have largely sunset. The 2026 CMS PFS preserves a more limited but still meaningful telehealth coverage framework. Permanent post-PHE telehealth coverage includes: behavioral health and substance use disorder treatment (broad coverage retained for established patients without geographic or originating-site restrictions), Federally Qualified Health Centers and Rural Health Clinics (geographic flexibility retained for specific services), end-stage renal disease monthly capitated services and stroke evaluation in the emergency setting (specific carve-outs retained). Telehealth coverage that has ended or narrowed: most non-behavioral established-patient telehealth that was broadly covered during PHE (some of this coverage has been extended on a year-by-year basis through legislation but is not permanent). Audio-only telehealth: significantly restricted compared to PHE; coverage retained for behavioral health and limited specific services. The practical implication: telehealth coverage in 2026 is highly service-specific and payer-specific. Practices billing telehealth must verify coverage for each specific code and each payer before delivering the service.

Modifier 95 (synchronous telemedicine service rendered via real-time interactive audio and video telecommunications system) is appended to the CPT code for any audio-and-video telehealth service. The modifier signals that the service was delivered via real-time interactive technology between the provider and patient who were in different physical locations. Documentation requirements: the chart must establish that the service was real-time interactive audio-and-video, the patient's location at the time of service must be documented (especially for POS 10 home telehealth), and the technology platform used must be HIPAA-compliant. Billing without modifier 95 on a telehealth claim typically results in denial or paid as in-person service, which can create audit exposure if reviewed. Common error: forgetting to append modifier 95 when shifting between in-person and telehealth scheduling within the same practice.

Modifier 93 (synchronous telemedicine service rendered via telephone or other real-time interactive audio-only telecommunications system) is appended to the CPT code for audio-only telehealth services where coverage is permitted. Audio-only coverage is much narrower than audio-and-video coverage. Where covered (currently primarily behavioral health for Medicare and limited specific services), modifier 93 must be used. Documentation requirements: same as modifier 95 plus explicit documentation that audio-only delivery was clinically appropriate for the service (often because the patient lacked video capability or had a clinical reason audio-only was preferred). Modifier 93 should not be used as a backup when video failed mid-session; that scenario is documented differently.

POS code 02 (Telehealth provided other than in patient's home) is used when the patient is at a physical originating site such as a hospital, clinic, FQHC, or RHC. POS code 10 (Telehealth provided in patient's home) is used when the patient is at home during the telehealth encounter. The distinction matters for payment and for coverage rules. Some payers pay POS 02 telehealth at the facility rate (lower) and POS 10 at the non-facility rate (higher); other payers reverse this; verify with each payer. The patient location must be documented in the chart for the POS to be supportable on audit. Common error: billing all telehealth as POS 02 by default when patients were at home (POS 10). Many EHRs do not auto-detect POS based on patient location; the front-end staff or provider must capture it correctly.

Behavioral health and substance use disorder treatment retained the broadest post-PHE telehealth coverage. Established-patient psychotherapy (90832, 90834, 90837), psychiatric diagnostic evaluation (90791, 90792), psychotherapy with E/M, and certain SUD treatment services are covered via telehealth without the geographic or originating-site restrictions that apply to most other specialties. Audio-only behavioral health telehealth is also covered with modifier 93. The coverage extends to commercial payers in most states because state mandates and parity laws often require behavioral health telehealth coverage. Practices delivering behavioral health via telehealth must still document modality, patient location, and technology used to support the modifier and POS billing.

Specialties outside behavioral health face more restrictive 2026 telehealth coverage. Medicare requires the patient to be at a designated originating site for most non-behavioral telehealth (with exceptions for specific services and rural areas). Some commercial payers continue broader coverage, but practices must verify by payer and by code. Common services that lost broad telehealth coverage post-PHE include routine primary care follow-ups for non-behavioral conditions, specialist consultations for non-behavioral conditions, and routine chronic disease management visits. Practices that built telehealth-heavy workflows during PHE need to revalidate which services are still covered via telehealth in 2026 and which require return to in-person delivery for billing purposes. The financial impact of misbilling telehealth as covered when it is not is meaningful: claims deny or pay at lower rates and audit exposure builds for the misbilled history.

Commercial payer telehealth policies vary significantly. UnitedHealthcare retained broader telehealth coverage than Medicare for many services post-PHE but tightened audit on telehealth billing accuracy. Aetna varies coverage by employer plan and by state. BCBS plans differ widely; some states have parity laws that require commercial coverage to match in-person, others do not. Cigna retained meaningful telehealth coverage but with payer-specific policy nuances. The practical implication: telehealth billing accuracy depends on payer-specific policy verification at the point of scheduling. Building a payer-specific telehealth coverage matrix into the scheduling workflow prevents billing errors. A simple internal tool: a spreadsheet listing each major payer with telehealth coverage rules per CPT category, updated quarterly. Practices that maintain this discipline avoid the post-service surprise of telehealth claims denying because the service was not covered via telehealth for that specific payer.

An audit-ready telehealth note documents five elements. Element one: explicit modality statement. 'Service delivered via synchronous audio-and-video telehealth using [HIPAA-compliant platform name].' For audio-only: 'Service delivered via synchronous audio-only telehealth via telephone.' Element two: patient location. 'Patient was at home in [city, state] at time of service.' Or: 'Patient was at [originating site name and address] at time of service.' Element three: provider location. 'Provider was at [office address] at time of service.' Element four: technology compliance. 'Platform used is HIPAA-compliant. Patient consent for telehealth on file.' Element five: clinical content same as in-person. The chart should not be shorter or less detailed because the encounter was telehealth. Auditors interpret thin documentation as evidence the service was not equivalent to in-person.

Telehealth billing is one of the higher-error workflows in physician billing because of payer variation, modifier and POS specificity, and frequent policy updates. Our process: payer-specific telehealth coverage matrices maintained quarterly across all client payer mixes, claim scrubber rules that verify modifier 95 or 93 application matches the documented modality, POS verification against patient location documentation, automated telehealth-coverage check at the time of scheduling so that practices know in advance whether a telehealth visit will be billable for the specific patient and payer combination. Pricing starts at 2.49 percent of net collections with no setup fees. The math: for a practice with significant telehealth volume, accurate telehealth billing prevents 5 to 10 percent of revenue loss to denials and downcoded telehealth claims.
