Top 6 Telehealth Billing and Reimbursement Challenges in 2026

You completed the telehealth visit, documented the encounter, and submitted the claim—but the reimbursement is still delayed or denied. For many healthcare providers, telehealth billing can be just as challenging as delivering virtual care.

As telehealth continues to expand across the USA, providers must keep up with changing Medicare policies, payer-specific requirements, coding updates, documentation standards, and reimbursement rules. A small billing mistake can lead to claim denials, delayed payments, rework, and lost revenue.

In 2026, one of the biggest challenges is that telehealth rules are no longer governed by a single set of temporary pandemic-era flexibilities. Medicare requirements differ based on the service, provider type, patient location, specialty, and setting. Commercial payers may also apply their own policies.

This guide covers the top six telehealth billing and reimbursement challenges in 2026 and practical ways providers can address them.

Challenge #1: Frequent Changes to Telehealth Reimbursement Policies

Telehealth reimbursement policies continue to evolve, making it difficult for providers and billing teams to keep their workflows current. Medicare telehealth requirements can vary depending on whether the service involves behavioral health, the provider type, the patient’s location, and the type of service being furnished.

For 2026, providers need to pay particular attention to several important Medicare changes.

01. Medicare Geographic and Originating-Site Restrictions

Through January 30, 2026, Medicare beneficiaries could generally receive telehealth services from anywhere in the United States and its territories under the applicable temporary flexibilities. Beginning January 31, 2026, many non-behavioral-health Medicare telehealth services became subject to geographic and originating-site requirements, while behavioral health services have broader rules and certain statutory exceptions continue to apply.

This means providers must verify the patient’s location and the applicable Medicare telehealth requirements before submitting a claim.

02. Provider Eligibility Varies

Provider eligibility is another important consideration. Medicare telehealth rules differ by practitioner type and service.

For example, the rules affecting physical therapists, occupational therapists, speech-language pathologists, and audiologists changed in 2026. CMS also extended certain telehealth services for PTs, OTs, and SLPs through December 31, 2027, so providers should verify the specific service and current eligibility requirements rather than applying a blanket rule.

03. RHC and FQHC Telehealth Requirements

Rural Health Clinics (RHCs) and Federally Qualified Health Centers (FQHCs) have specific telehealth billing rules.

CMS allows eligible non-behavioral-health telehealth services furnished by RHCs and FQHCs to continue using HCPCS code G2025 through December 31, 2027, including eligible audio-only services. CMS also provides specific rules for behavioral health services furnished through telecommunications technology.

04. Behavioral Health In-Person Visit Requirements

Medicare has specific in-person requirements for certain mental health telehealth services furnished to patients in their homes. Under current CMS guidance, the statutory in-person requirement applies after December 31, 2027. For patients who begin receiving applicable mental health telehealth services before January 1, 2028, different transition rules apply, including an ongoing in-person visit requirement after that date.

05. Controlled-Substance Teleprescribing Rules

Telehealth providers who prescribe controlled medications must also monitor DEA requirements. The DEA and HHS extended the current federal telemedicine flexibilities for prescribing controlled medications through December 31, 2026. Under the temporary extension, eligible DEA-registered practitioners can prescribe certain Schedule II-V controlled medications through telemedicine when applicable federal and state requirements are met.

How to Overcome Policy Challenges

01. Monitor CMS and Payer Updates

Regularly review CMS guidance, Medicare telehealth updates, and individual payer policies. Do not rely on outdated telehealth billing policies or previous-year workflows.

02. Update Billing Workflows

Update your billing software, coding references, payer rules, and internal checklists whenever telehealth requirements change.

03. Verify Patient and Provider Requirements

Before claim submission, confirm the patient’s location, provider eligibility, service type, payer coverage, and applicable telehealth requirements.

Challenge #2: Complexity of Telehealth Billing Codes and Modifiers

Telehealth billing involves more than selecting a CPT code. Providers may need to consider CPT or HCPCS codes, modifiers, place of service codes, service-specific requirements, documentation, and payer policies.

Medicare maintains a 2026 list of services payable when furnished through telehealth, and CMS updates the list through its annual rulemaking process.

Using an incorrect code, modifier, or billing method can cause a claim to be rejected or denied.

Common coding problems include:

Reporting a code that is not eligible for telehealth.
Using the wrong telehealth modifier.
Incorrectly reporting audio-only services.
Selecting an inappropriate place of service code.
Failing to meet service-specific documentation requirements.
Applying Medicare rules to a commercial payer without verification.

2026 RTM Coding Updates

Remote therapeutic monitoring (RTM) is another area providers need to monitor. CMS added new RTM codes 98979, 98984, and 98985 beginning January 1, 2026, while also revising descriptors for existing RTM codes such as 98976 and 98977.

These updates make it important for providers to verify current code descriptors and payer requirements instead of relying on older coding references.

How to Overcome Telehealth Coding Challenges

01. Maintain an Updated Code Library

Keep CPT, HCPCS, modifier, and telehealth billing references updated for the current calendar year.

02. Train Billing and Coding Staff

Provide regular training whenever CMS, Medicaid, Medicare Advantage, or commercial payer policies change.

03. Conduct Coding Audits

Review telehealth claims regularly to identify incorrect codes, modifiers, place of service codes, and documentation gaps.

04. Verify Payer Requirements

Before submitting a claim, confirm that the payer covers the service and accepts the selected code, modifier, and telehealth delivery method.

Challenge #3: High Rates of Telehealth Claim Denials

Claim denials remain one of the biggest financial challenges for telehealth providers. A claim may be denied even when the provider delivered the service correctly if the billing information does not meet the payer’s requirements.

Common causes of telehealth claim denials include:

Incorrect CPT or HCPCS codes.
Incorrect modifiers.
Wrong place of service coding.
Missing or incomplete documentation.
Patient eligibility issues.
Lack of prior authorization when required.
Services that are not covered by the patient’s plan.
Incorrect patient or provider location information.
Duplicate claim submissions.
Failure to follow payer-specific telehealth policies.

How to Reduce Telehealth Claim Denials

01. Verify Patient Eligibility

Confirm active insurance coverage and telehealth benefits before providing the service whenever possible.

02. Check Coding Before Submission

Review the CPT or HCPCS code, modifier, place of service, diagnosis, and other claim details before submission.

03. Follow Payer-Specific Rules

Do not assume that a telehealth service covered by Medicare is automatically covered by every commercial payer.

04. Monitor Denial Trends

Track denial reasons by payer, provider, code, and service type. Identifying recurring problems can help prevent future denials.

05. Strengthen Documentation

Ensure documentation supports the service billed, medical necessity, patient encounter, and applicable telehealth requirements.

Challenge #4: Specialty-Specific Telehealth Billing Requirements

Telehealth billing is not the same across every healthcare specialty. Behavioral health, primary care, therapy, remote patient monitoring, and other specialties can have different coding, documentation, coverage, and reimbursement requirements.

01. Behavioral Health

Behavioral health telehealth has specific Medicare requirements, particularly for services delivered to patients in their homes. Providers need to monitor applicable in-person visit requirements and document services appropriately.

02. Remote Patient Monitoring

RPM services require appropriate codes, patient eligibility, device-related requirements, data collection, and documentation. Providers should verify current Medicare and commercial payer policies before billing.

03. Remote Therapeutic Monitoring

RTM billing continues to evolve. CMS introduced new RTM codes for 2026, making it important for therapy providers and billing teams to use the current code set and understand applicable therapy requirements.

04. Therapy Services

Therapy providers need to pay close attention to provider eligibility and service-specific requirements. CMS’s 2026 updates include continued telehealth authority for certain therapy professionals and new RTM coding changes.

How to Overcome Specialty-Specific Challenges

01. Build Specialty-Specific Billing Workflows

Create separate workflows for behavioral health, therapy, RPM, RTM, and other telehealth services.

02. Keep Specialty Coding References Current

Update code libraries and billing guidelines whenever new CPT or HCPCS codes become effective.

03. Audit Documentation

Regular documentation audits can identify missing information before it causes denials or payment delays.

04. Verify Coverage Before Service

Confirm that the patient’s insurance covers the specific telehealth service and delivery method.

Challenge #5: Workflow Inefficiencies and Billing Software Gaps

Even when providers understand telehealth billing requirements, inefficient workflows can create revenue problems.

Manual data entry, disconnected EHR and billing systems, outdated coding libraries, incomplete eligibility checks, and poor communication between clinical and billing teams can increase administrative work and create avoidable claim errors.

Common workflow problems include:

Manual patient eligibility verification.
Outdated CPT and HCPCS code libraries.
Missing telehealth modifiers.
Incomplete patient information.
Poor EHR-to-billing system integration.
Delayed claim submission.
Lack of automated claim edits.
Limited denial tracking.

How to Improve the Telehealth Billing Workflow

01. Use Updated Billing Technology

Choose systems that support current coding references, claim edits, eligibility verification, and payer-specific requirements.

02. Connect Clinical and Billing Systems

Integrating clinical and billing information can reduce duplicate data entry and missing claim information.

03. Standardize the Billing Process

Create a consistent workflow from scheduling and eligibility verification through documentation, coding, claim submission, and payment posting.

04. Automate Repetitive Tasks

Automation can help with eligibility checks, claim scrubbing, coding validation, and denial alerts.

05. Train Staff Regularly

Technology cannot replace knowledgeable billing staff. Ongoing training helps teams respond to coding and payer changes more effectively.

Challenge #6: Revenue Cycle Risks in Telehealth Billing

Telehealth can improve patient access, but billing problems can still create significant revenue cycle risks. Changing Medicare requirements, payer-specific coverage rules, coding errors, and delayed claim follow-up can all affect cash flow.

01. Claim Denials

Incorrect coding, eligibility issues, missing documentation, and payer-specific errors can result in unpaid claims.

02. Reimbursement Variability

Telehealth reimbursement may differ based on the payer, service, provider type, location, and applicable coverage policy.

03. Private Payer Differences

Commercial insurers may have different telehealth coverage and billing requirements. A workflow that works for one payer may not work for another.

04. Compliance and Audit Risk

Incomplete documentation, incorrect coding, and failure to follow applicable telehealth requirements can increase compliance risk.

05. Cash Flow Disruptions

Unresolved denials and delayed claims can increase accounts receivable and make revenue less predictable.

How to Reduce Telehealth Revenue Cycle Risks

01. Strengthen Denial Management

Identify the root cause of each denial, correct the claim when appropriate, and submit appeals or corrected claims within the payer’s required timeframe.

02. Improve Documentation

Make sure clinical documentation supports the service, diagnosis, medical necessity, and applicable telehealth requirements.

03. Monitor Billing Performance

Track denial rates, days in A/R, reimbursement trends, outstanding claims, and payer-specific problems.

04. Review Payer Policies Regularly

Create a process for monitoring changes in Medicare, Medicaid, Medicare Advantage, and commercial payer policies.

05. Consider Professional Billing Support

Specialized telehealth billing support can help practices manage coding, claim submission, denial follow-up, and changing payer requirements.

How to Prevent Telehealth Billing and Reimbursement Problems in 2026

Although telehealth rules can be complex, providers can reduce billing problems by building a proactive process.

Here are some practical steps:

Verify eligibility and telehealth benefits before the encounter.
Confirm patient and provider locations when required.
