Medical Billing for Telehealth: What Independent Practices Get Wrong
Telehealth billing errors are among the most common claim rejection categories at independent practices in 2026, and most of them trace back to one source: billing rules that changed when the COVID public health emergency waivers expired and practices that have not updated their workflows to match. The most costly errors -- wrong place-of-service code, missing modifier, audio-only billed as audio-video -- generate payer rejections or overpayment demands that are expensive to correct retroactively.
This article provides general operational guidance on medical billing practices. It is not legal, compliance, or financial advice. Consult qualified healthcare billing counsel or a certified professional coder for your specific situation.
HIPAA compliance requirements vary based on your covered entity type and business associate relationships. Consult your HIPAA compliance officer or a healthcare attorney before implementing privacy practices.
Credentialing and enrollment requirements vary by payer and change frequently. Verify current requirements directly with each payer.
The Short Answer
Telehealth billing in 2026 is not the waiver-era billing of 2020-2023. The core rules are now permanent for Medicare (following the CAA 2023 and subsequent legislation), but commercial payers have diverged significantly in how they apply them. Your billing team needs a current written reference for each payer's telehealth rules -- not a 2022 training that has not been updated.
| Payer | POS for Video Telehealth | POS for Audio-Only | Modifier Required | Coverage Notes |
|---|---|---|---|---|
| Medicare | 02 (telehealth remote) | 02 (if covered) | 95 (synchronous) | PHE flexibilities extended; verify annually |
| Medicare Advantage | Payer-specific (often 02) | Payer-specific | Payer-specific | Varies significantly by plan -- verify per contract |
| Commercial (large national) | 02 or 11 (payer-specific) | Often not covered | GT or 95 (payer-specific) | State parity laws affect coverage scope |
| Medicaid Managed Care | 02 (most plans) | Limited (state-dependent) | State-specific | Per state Medicaid plan terms |
Telehealth billing rules change frequently. Verify current POS codes, modifier requirements, and covered service lists directly with each payer before billing. CMS updates Medicare telehealth policy annually. Commercial payer rules vary by state parity law.
Place-of-Service Codes: The Most Common Error
The place-of-service (POS) code on a telehealth claim tells the payer where the patient was located during the service, not where the provider was. This is the single most confusing element of telehealth billing and the most common source of rejections.
- POS 02 (Telehealth, patient not in home): Use when the patient receives the telehealth service from a location other than their home -- a healthcare facility, an employer site, or another setting. This code existed before the COVID waivers.
- POS 10 (Telehealth, patient in home): Added during the COVID PHE; now permanent for Medicare. Use when the patient is in their home for the telehealth visit. This is the correct code for the majority of consumer-facing telehealth visits in 2026.
- POS 11 (Office): This is NOT correct for telehealth visits even if the provider is in the office. POS code applies to the patient location. Billing POS 11 for a telehealth visit where the patient is at home is a billing error that can trigger overpayment recovery.
Review your practice's POS code usage for all telehealth claims from the past 12 months. If POS 11 is appearing on claims where the patient was at home, that is a coding error requiring a corrective action plan.
Modifier Requirements
Telehealth claim modifiers communicate additional information about the service type to the payer. The critical modifiers in 2026:
- Modifier 95: Appended to the CPT code to indicate the service was delivered via synchronous real-time audio-video telehealth. Required for most commercial payer telehealth claims. Medicare does not require modifier 95 but accepts it; many commercial payers require it.
- Modifier FQ: Medicare-specific. Indicates the service was furnished using audio-only communication technology. Required by Medicare for audio-only services where audio-only is covered. Not all Medicare services are payable as audio-only -- check the current Medicare telehealth services list for audio-only eligibility by CPT code.
- Modifier GT: Older modifier previously used for interactive audio-video. Medicare phased this out in favor of the POS code structure, but some commercial payers still require it. Verify per payer.
Do not assume modifiers are consistent across payers. Aetna, United, Cigna, and BCBS each have their own modifier requirements for telehealth, and those requirements have changed multiple times since 2020. Your clearinghouse should have payer-specific modifier requirement lookups -- use them.
Audio-Only Telehealth: The Most Misunderstood Coverage Category
Audio-only telehealth (phone visits without video) is covered by Medicare for certain services for patients who cannot access audio-video technology. It is NOT covered by Medicare for all services that are covered via audio-video telehealth. The Medicare telehealth services list specifies which CPT codes are eligible for audio-only billing separately from audio-video billing.
Commercial payers have highly variable audio-only coverage. Some payers cover audio-only for all telehealth services covered by audio-video; others exclude audio-only entirely; others cover a narrow list of services. Treating audio-only billing rules as uniform across commercial payers is the most common telehealth billing assumption error at independent practices.
Medicare vs. Commercial Payer Rules
Medicare telehealth rules are now largely permanent following the Consolidated Appropriations Acts and subsequent legislation. Key permanent Medicare telehealth provisions as of 2026:
- Patients can receive telehealth from their home (POS 10) without a prior in-person visit requirement for most services.
- The originating site restriction (requiring patients to be in a rural area or healthcare facility) has been lifted for most services.
- Mental health services via telehealth require an in-person visit within 12 months -- this is the most significant exception to the general removal of originating site restrictions.
Commercial payers are not bound by Medicare telehealth rules. Some commercial payers align with Medicare's expanded telehealth coverage; others have narrower lists of covered telehealth services or require additional documentation. State insurance mandates also affect what commercial payers must cover for telehealth -- verify your state's current telehealth parity laws.
What Goes Wrong
- Using 2022 training materials: Telehealth billing rules changed with PHE expiration, the CAA 2023, and subsequent CMS rulemaking. Training materials from the waiver period describe rules that no longer apply for Medicare and many commercial payers. Update your telehealth billing reference annually.
- Not verifying telehealth coverage at eligibility check: A patient being covered by a payer does not mean their specific plan covers telehealth. Verify telehealth benefit inclusion at the time of scheduling -- not all plans under the same commercial payer have the same telehealth coverage terms.
- Billing audio-only as audio-video: Submitting a claim with POS 02 or 10 and modifier 95 for a service that was actually conducted audio-only (because the patient could not connect video) is a billing error even if the clinical documentation is accurate. If a visit was audio-only, it must be billed as audio-only per the applicable rules.
Documentation Requirements That Trip Up Telehealth Claims
Independent practices often assume that telehealth visits require the same documentation as in-office encounters, but payers have added specific requirements that must appear in the medical record to support telehealth billing. Missing even one of these elements can trigger a denial or audit flag.
Every telehealth encounter must explicitly document the modality used--whether the visit occurred via two-way video, audio-only phone, or asynchronous store-and-forward technology. The location of both the patient and the provider should be recorded, especially for state licensure compliance. Many payers also require documentation that the patient consented to receive care via telehealth, and that consent should be noted in the chart before or during the first telehealth visit.
Another frequently overlooked element is the technology platform used. While this may seem administrative, some payers require confirmation that the platform meets HIPAA security standards. If your practice uses a patient portal, standard phone line, or consumer video app, that choice affects both compliance and reimbursement eligibility. Document what was used and ensure it aligns with your payer contracts.
Finally, clinical notes should describe the visit in enough detail to justify the level of service billed. A brief note that reads "telehealth visit completed" will not satisfy payer audits. Document the history, exam components performed remotely, medical decision-making, and time spent just as you would for an in-person encounter.
Bottom Line
Telehealth billing in 2026 requires a current, payer-specific reference document that your billing team actually uses before submitting claims. The most common errors -- wrong POS code, wrong modifier, audio-only billed as audio-video -- are all preventable with correct upfront training and payer-specific checklists. A retroactive billing error audit on telehealth claims from the past 24 months is worth running at any practice that has not reviewed its telehealth billing practices since the PHE expired.

Frequently Asked Questions
- Do commercial payers require providers to use specific telehealth platforms?
- Some commercial payers have preferred telehealth platform requirements or require platforms that meet specific security standards (HIPAA-compliant encryption, minimum bandwidth requirements). Most commercial payers do not mandate a specific platform but require that the platform be synchronous and audio-video capable for audio-video claims. Verify your payer contracts and EOC documents for any platform requirements before selecting a telehealth solution.
- What documentation is required for a telehealth claim to support medical necessity?
- Documentation requirements for telehealth services are the same as for in-person services of the same type. For E&M services delivered via telehealth, the note must support the level of service billed using the same 2021 AMA E&M guidelines (medical decision making or time-based documentation). Additional documentation recommended for telehealth claims: notation that the service was delivered via audio-video (or audio-only), confirmation that the patient consented to telehealth, and the patient's location at the time of the visit.
- How should a practice handle a telehealth claim denied for a place-of-service error?
- A POS denial on a telehealth claim is typically correctable on first-level appeal. Submit a corrected claim (not a formal appeal) with the correct POS code -- POS 02 for audio-video, POS 10 for audio-only in states where that code is accepted -- within the payer's timely filing window for corrected claims. Include a brief cover note confirming that the original claim used an incorrect POS code and the service was delivered as a synchronous telehealth encounter. Most payers accept corrected claims for POS errors without a formal appeal. If a formal appeal is required, attach the telehealth consent documentation and the clinical note confirming the modality used.
- What should a practice do when a commercial payer telehealth policy conflicts with Medicare?
- Commercial payer telehealth policies are independent from Medicare policy. A service that Medicare reimburses for telehealth may not be covered by a commercial payer, and vice versa. The correct approach: maintain a payer-specific telehealth coverage grid for your top 5-8 payers by volume, reviewing each payer's telehealth coverage document before billing a new telehealth service type. Do not assume commercial coverage mirrors Medicare. This is one of the most common billing errors in practices that shifted from Medicare to a commercial payer telehealth program and assumed coverage parity.
- How does audio-only telehealth billing differ from audio-video in 2026?
- Audio-only telehealth billing uses a separate set of codes and place-of-service designations from audio-video visits. For Medicare in 2026, audio-only services are covered for established patients in specific clinical circumstances -- verify the current list at CMS.gov, as covered services and payment levels have been subject to annual policy changes since the end of the Public Health Emergency. For commercial payers, audio-only coverage varies significantly; many plans that covered audio-only during the PHE have since restricted coverage to audio-video only. Verify your payer-specific audio-only coverage annually before the plan year begins, and update your telehealth billing grid accordingly.
- Can I bill telehealth and an in-person visit on the same day?
- Generally, no. Most payers do not allow separate billing for a telehealth visit and an in-person evaluation and management service on the same day by the same provider. If a patient is seen via telehealth in the morning and then comes to the office later that day, you typically must bill only one E/M service that reflects the total work performed.
- Do I need a separate NPI for telehealth billing?
- No. You use the same National Provider Identifier for telehealth services as you do for in-person care. The place-of-service code and modifiers indicate that the service was delivered via telehealth--your NPI remains unchanged regardless of visit modality.
