Telehealth Billing Guidelines for 2026: A Professional Guide

A wrong POS code, a missing modifier, a service that isn’t actually covered under the patient’s plan via telemedicine, or documentation that doesn’t reflect how the visit was conducted – any of these produces a denial. This telehealth billing guide covers the key decision points for 2026 so billing teams can catch errors before they reach the payer.

Determine the Correct Place of Service Codes

POS selection is the first place telehealth claims go wrong. The code has to reflect where the patient was located during the visit, not where the provider was. Getting this backwards is common, and payers will deny or reduce payment on claims where POS doesn’t match the clinical circumstances.

Two codes cover the majority of telehealth visits in 2026:

POS 02 was the original telehealth code, introduced when patients had to travel to an originating site to receive remote care. POS 10 was added to reflect the reality of patients connecting from home. Most visits today should carry POS 10, but billing teams sometimes default to POS 02 out of habit. Medicare pays the same facility rate for both codes, but commercial payers may apply different rules, so confirming the patient’s actual location at the time of service matters for accuracy and compliance.

Use Telehealth Modifiers Correctly

Modifiers tell the payer how a telehealth service was delivered. They don’t change what was billed – they clarify the circumstances. The issue is that modifier rules are not consistent across payers, and applying the wrong one, or omitting a required one, can result in denial or reduced reimbursement.

Modifier GT was commonly used before 2022 but has been largely replaced by modifier 95 for Medicare claims. Some commercial payers still require GT, so the billing team needs to verify current requirements per payer rather than applying a single modifier across all claims. Payer telehealth modifier requirements change and assuming last year’s rules still apply is a reliable way to generate avoidable denials.

Confirm Covered Services and Provider Eligibility

Not every CPT code is billable via telehealth, and not every provider type is eligible to deliver covered telehealth services under every payer. Medicare maintains a published telehealth services list that is updated annually. A service that was temporarily added during the public health emergency may no longer be permanently covered, and coding it as a telehealth visit when coverage has lapsed will produce a denial.

Provider type matters as well. Under Medicare, physician assistants, nurse practitioners, clinical psychologists, licensed clinical social workers, and certified nurse midwives are among the provider types eligible to bill telehealth services. Some newer provider categories gained telehealth billing eligibility during the PHE under temporary rules that are still being evaluated for permanent status. Verifying that the rendering provider type is eligible under the specific payer’s telehealth policy is a step that gets skipped more often than it should.

For Medicaid, eligibility rules vary by state, and Georgia’s managed care plans, for example, apply different telehealth coverage rules than plans in other states. Commercial payers add another layer of variation. The safest practice is a payer-specific check before the visit rather than an assumption based on what was covered for a different payer last month.

Document Telehealth Encounters for Billing Accuracy

The right code and modifier still require documentation that supports the claim. Telehealth billing doesn’t reduce documentation requirements – it adds a few that don’t apply to in-person visits.

Documentation for a telehealth encounter should include:

• The technology used to conduct the visit (audio-video platform, phone call, or other telecommunications system)
• Patient location at the time of the visit, confirming the appropriate POS code
• Confirmation that the patient consented to the telehealth visit, which some payers require to be documented in the chart
• The same clinical content required for an equivalent in-person visit: presenting complaint, relevant history, assessment, and plan
• Provider identity when relevant, particularly for services where the rendering provider type affects billing eligibility

Telehealth documentation audits are becoming more common as payer post-payment review programs catch up with the volume of telehealth claims filed since 2020. A chart that doesn’t clearly establish how the visit was conducted and why it qualifies as a covered telehealth service is a liability in that environment.

Distinguish Audio-Video From Audio-Only Billing Rules

Audio-video and audio-only visits follow different billing logic, and the gap between them is significant under Medicare. The standard telehealth benefit requires interactive audio and video telecommunications – a phone call alone does not qualify for most codes on the Medicare telehealth services list.

Audio-only coverage under Medicare has been available under certain conditions since the PHE and has been extended with some restrictions. Under current rules, audio-only billing for behavioral health services is permitted when the patient is in a rural area or lacks access to audio-video technology, with additional documentation requirements to support the use of audio-only. For most other service types under Medicare, audio-only does not support a telehealth claim.

Commercial payers and Medicaid managed care plans have their own audio-only policies, some more permissive than Medicare and some more restrictive. Billing staff should not assume that a plan’s general telehealth coverage extends to audio-only visits without a specific policy confirmation. The codes, modifiers, and documentation requirements for audio-only are distinct enough that they need to be handled separately from standard audio-video telehealth claims.

Stay Aligned With Payer-Specific Telehealth Policies

Medicare sets the baseline for telehealth billing, but it doesn’t set the standard that all payers follow. Medicaid programs are state-administered, which means a telehealth service covered under Georgia Medicaid may not be covered under Texas Medicaid, and neither reflects what a commercial plan requires.

Commercial payers frequently update their telehealth policies, sometimes mid-year and sometimes without direct notification to providers. A plan that covered a specific telehealth code last quarter may have updated its medical policy since then. Practices that review payer telehealth policies once a year and assume stability in between are the ones most frequently surprised by denials on services they thought were covered.

The practical approach is a payer-specific policy file that gets reviewed at least quarterly for high-volume payers, and a verification step built into the authorization or eligibility check workflow for new patients or unfamiliar plan types. Telehealth policy changes are frequent enough that assuming consistency is a billing risk.

Use Technology to Reduce Telehealth Billing Errors

Most telehealth billing errors are systematic rather than random. The same POS code gets applied to every claim regardless of patient location. Modifier 95 gets added by default without checking whether the payer requires a different one. Documentation templates don’t prompt the provider to capture telehealth-specific fields. These patterns produce consistent, predictable denials, and they’re the kind of problem that technology can address at the workflow level rather than claim by claim.

EHR systems that prompt providers to document visit modality and patient location during chart completion reduce the gap between what happened clinically and what the billing team receives to work with. Claim scrubbing tools that include telehealth-specific edits catch POS mismatches and modifier errors before submission. Eligibility verification tools that flag telehealth coverage status give the billing team information to act on before the visit occurs rather than after the denial arrives.

The goal isn’t to add technology for its own sake. It’s to remove the manual steps where telehealth billing errors consistently enter the process.

How Swift MDS Helps Improve Telehealth Billing Workflows

Telehealth billing adds complexity to every stage of the revenue cycle: eligibility checks need to confirm telehealth coverage, coding decisions depend on visit modality and patient location, documentation requirements are different from in-person visits, and payer rules change often enough that what worked last quarter may not work today.

Swift MDS supports practices managing telehealth billing alongside broader billing operations, with the coding accuracy, payer-specific knowledge, and denial follow-through the work requires:

• RCM Services – revenue cycle management that incorporates telehealth-specific coding, POS accuracy, and modifier compliance into the standard billing workflow
• Denial Management Services – structured review and appeal of telehealth-related denials, with root cause tracking to stop the same errors from recurring
• Medical Billing Outsourcing – full billing management for practices that need telehealth and in-person claims handled together by a team that knows the difference
• Medical Billing Audit Services – independent review of telehealth coding, documentation, and modifier use to identify compliance gaps before a payer audit does

Outlook: Protecting Telehealth Reimbursement

Telehealth billing in 2026 rewards practices that treat it as a distinct billing category rather than an extension of in-person visit coding. POS accuracy, modifier discipline, service eligibility verification, documentation quality, and payer-specific policy tracking are not optional details. Each one is a point where a preventable denial enters the revenue cycle.

If telehealth denials are a recurring issue in your practice or your current billing process doesn’t have clear telehealth-specific workflows, contact Swift MDS to discuss how to close those gaps and protect the reimbursement your telehealth services have already earned.
