Telehealth Insurance Claim Denied? How to Appeal

Telehealth had a transformative breakthrough during the COVID-19 pandemic. Emergency orders expanded coverage dramatically, patients adapted quickly, and the technology proved itself across hundreds of millions of visits. Then the federal Public Health Emergency ended in May 2023, coverage contracted in many plans, and patients started receiving denials for the same type of telehealth visits that had been covered just months before. If you are dealing with a telehealth insurance denial, you are navigating a coverage landscape that has shifted significantly — and understanding the specific legal framework applicable to your situation is essential.

The good news: many telehealth denials are overturned on appeal because they involve billing errors, parity law violations, or coverage contractions that conflict with applicable state law. A precise, well-documented appeal that identifies the correct legal ground for your challenge is highly effective.

Why Insurers Deny Telehealth Claims

Originating site restrictions were the pre-pandemic Medicare rule requiring patients to be located in a qualifying rural health professional shortage area at the time of the telehealth visit. This restriction was widely waived during the PHE. Congress extended many of these waivers through 2026 and beyond. If your Medicare or Medicare Advantage plan is denying on originating site grounds, cite the applicable Congressional extension of telehealth flexibilities.

Service type not covered via telehealth arises because not every clinical service that can theoretically be delivered via video qualifies for telehealth reimbursement under a given plan. Mental health services (ICD-10: F00–F99), primary care visits, and certain specialist consultations are generally covered under state parity laws; others — such as certain diagnostic procedures — may legitimately require in-person visits. Check your plan's telehealth-eligible service list and compare it against your state's telehealth parity statute.

Provider not eligible for telehealth billing affects certain provider types. Licensed clinical social workers (LCSW), marriage and family therapists (MFT), and out-of-state providers face telehealth billing eligibility limitations that vary by plan and state. If your provider billed for a telehealth service they were not credentialed to provide under your specific plan, the billing error is the first thing to address — often with a corrected claim submission rather than a formal appeal.

Audio-only visit not covered reflects the ongoing distinction many plans and states draw between video telehealth (broadly covered) and audio-only telephone calls (covered at a lower rate or not covered). If your visit was conducted by phone rather than video, determine whether your plan covers audio-only visits and whether your state's parity law extends to telephone consultations.

Parity law not applied correctly occurs when plans cover in-person behavioral health visits but deny the telehealth equivalent of the same service. The Mental Health Parity and Addiction Equity Act (MHPAEA) requires that mental health and substance use disorder benefits be provided at parity with medical and surgical benefits — including telehealth equivalents. If your plan covers in-person therapy but denies the identical telehealth visit, this is a potential parity violation.

How to Appeal a Denied Telehealth Insurance Claim

Step 1: Get the Denial in Writing with the Specific Ground

Request the EOB)" class="auto-link">Explanation of Benefits and formal denial notice identifying the exact plan provision, originating site rule, or coverage limitation cited. You cannot build an effective appeal without knowing precisely what you are challenging. For Medicare or Medicare Advantage denials, also request the specific CMS coverage rule or plan evidence of coverage provision cited.

Step 2: Determine Whether a State Parity or Telehealth Law Applies

More than 40 states have enacted telehealth parity laws requiring insurers to cover telehealth services at the same rate as equivalent in-person services. Several states — including California (Business and Professions Code § 2290.5), New York, Texas, and Illinois — have particularly strong statutes. Check your state insurance commissioner's website and compare the applicable law against your plan's denial. If you are in a parity state and the denial conflicts with the parity statute, that is the core of your appeal.

Step 3: Check for Billing and Coding Errors

Contact your telehealth provider's billing department and verify the place of service (POS) code, CPT code, and modifier used on the claim. The correct codes are: POS 02 (telehealth, non-home), POS 10 (telehealth, patient's home), and modifier GT or 95 for synchronous audio-video telecommunications. If the wrong code was used, request a corrected claim submission rather than pursuing a formal appeal — this resolves many telehealth denials faster.

Step 4: Gather Clinical and Provider Documentation

Obtain the provider's clinical visit summary, the diagnosis (with ICD-10 code), and a statement from the provider confirming that the telehealth visit was medically appropriate and compliant with applicable state and federal telehealth coverage requirements. For mental health telehealth denials, reference the MHPAEA parity requirements and your state's parity statute.

Step 5: Write Your Appeal Letter Addressing the Specific Denial Ground

Pair the legal framework with the clinical facts. If the denial cites "service not covered via telehealth," cite your state parity law and the in-person equivalent your plan covers. If the denial involves an originating site restriction, cite the Congressional extension of Medicare telehealth flexibilities. If the denial involves a billing error, reference the corrected claim submission. Submit via certified mail or the insurer's secure member portal and retain copies.

Step 6: File a State Insurance Department Complaint if the Appeal Fails

Telehealth parity violations and post-PHE coverage contractions that conflict with state law are appropriate subjects for state insurance department complaints. Filing a complaint triggers regulatory review and often prompts faster reconsideration than the internal appeal process alone.

What to Include in Your Appeal

• Explanation of Benefits and formal denial notice with the specific denial reason
• Provider's clinical notes, ICD-10 diagnosis code, and CPT code for the telehealth visit
• Applicable state telehealth parity statute and comparison to the in-person equivalent service covered by your plan
• Provider letter confirming the visit was medically appropriate and conducted via the correct telehealth modality
• For Medicare or Medicare Advantage: the applicable Congressional extension of telehealth flexibilities
• Corrected claim documentation (if the denial was billing-related)

Fight Back With ClaimBack

Telehealth denials are frequently technical or regulatory in nature — wrong billing codes, state parity law violations, or post-pandemic coverage changes that conflict with applicable law. A focused appeal that identifies the exact legal or billing error and pairs it with clinical documentation from your provider is highly effective at reversing these decisions.
