Private Insurance Telehealth Parity Laws
Private insurance telehealth parity laws require commercial health insurers to cover telehealth services on terms comparable to in-person care — governing reimbursement rates, cost-sharing, and covered service types. These laws exist at the state level, creating a patchwork of obligations that varies significantly by jurisdiction. Understanding parity law scope is essential for providers, plan administrators, and patients navigating state telehealth laws and policies and the broader telehealth regulatory framework in the United States.
Definition and scope
Telehealth parity laws, in the context of private insurance, fall into two distinct categories: coverage parity and payment parity.
Coverage parity laws prohibit insurers from denying coverage for a service solely because it is delivered via telehealth when the same service would be covered if delivered in person. Payment parity laws go further, requiring that reimbursement rates for telehealth services equal the rates paid for equivalent in-person services.
As of 2024, 43 states and the District of Columbia have enacted some form of telehealth coverage parity law for private insurers, according to the American Telemedicine Association (ATA). Payment parity requirements are less uniform: fewer than half of those jurisdictions mandate equivalent reimbursement rates, and the specifics — which plan types are covered, which service modalities qualify, and which specialties are included — vary by state statute.
Key definitional elements that appear in most state parity statutes:
- Covered services — the list of CPT or HCPCS codes that qualify for parity treatment
- Modality requirements — whether audio-only, video, or store-and-forward delivery counts (see synchronous vs asynchronous telehealth)
- Eligible plan types — individual, group, and/or self-insured plans subject to the law
- Geographic scope — whether rural-only provisions apply or the law covers all service areas
Self-insured employer plans governed by the Employee Retirement Income Security Act of 1974 (ERISA) are generally exempt from state parity mandates, because ERISA preempts state insurance regulation for those plans (29 U.S.C. § 1144). This is a critical boundary: an estimated 60% of covered workers in the United States are enrolled in self-insured plans, according to the Kaiser Family Foundation 2023 Employer Health Benefits Survey.
How it works
When a state telehealth parity law applies to a commercial plan, the mechanism operates through the insurer's benefit design and claims processing rules.
Step-by-step operational structure:
- Benefit determination — The insurer identifies whether the requested service is covered under the enrollee's plan when delivered in person.
- Modality check — The insurer verifies that the telehealth delivery method used (live video, audio-only, store-and-forward) satisfies the modality definition in applicable state statute.
- Cost-sharing application — Under coverage parity, the insurer may not impose higher deductibles, copays, or coinsurance for telehealth than for comparable in-person services, unless the statute explicitly permits differential cost-sharing.
- Reimbursement rate calculation — In states with payment parity, the insurer must apply the same fee schedule rates to telehealth claims as to in-person claims for equivalent CPT/HCPCS codes.
- Denial and appeals — If a claim is denied on the basis of delivery modality in a parity state, the denial may constitute a statutory violation subject to state insurance commissioner review.
State insurance commissioners hold primary enforcement authority over parity compliance for fully insured plans. The National Association of Insurance Commissioners (NAIC) publishes model telehealth legislation that states may adopt, providing a reference baseline for statutory language (NAIC Model Act on Telehealth).
Parity laws do not generally compel insurers to cover services that have no in-person analogue in the plan's existing benefit structure. The parity principle is comparative: it attaches to services already covered, not to new service categories.
Common scenarios
Scenario 1: Mental health telehealth visit
A patient in a parity state uses a live video session with a licensed therapist. The plan covers in-person psychotherapy under CPT code 90837. Under coverage parity, the plan cannot deny the telehealth claim solely because the session was conducted remotely. Under payment parity (where applicable), the provider must receive the same rate as for an office visit. Mental health telehealth is among the highest-volume parity use cases, given the growth documented in telehealth mental health and behavioral services.
Scenario 2: Audio-only primary care
A patient without reliable broadband access calls a physician for a follow-up visit. Many state statutes enacted before 2020 defined telehealth as requiring live video, excluding audio-only. States that updated their statutes after 2020 — in response to COVID-19 policy changes (see telehealth COVID-19 policy changes) — may now include audio-only in covered modalities. Whether the parity obligation attaches depends entirely on the modality language of the applicable statute.
Scenario 3: ERISA self-insured employer plan
An employee enrolled in a self-insured plan requests telehealth coverage equal to in-person coverage. State parity law does not apply. The plan's telehealth benefit is governed solely by the plan document and any federal requirements — there is no state-level parity obligation the employer must follow.
Scenario 4: Employer-sponsored fully insured plan
If the employer purchases a fully insured policy from a licensed carrier, state parity law does apply to the insurer, because the plan is subject to state insurance regulation rather than ERISA preemption.
Decision boundaries
Determining whether a parity law applies to a specific claim or plan requires evaluating four discrete factors:
| Factor | Parity Applies | Parity Does Not Apply |
|---|---|---|
| Plan funding | Fully insured | Self-insured (ERISA) |
| State statute | Enacted coverage/payment parity | No parity statute or service excluded |
| Service type | Covered in-person by the plan | Not covered in-person |
| Delivery modality | Modality defined as telehealth in statute | Modality excluded from statutory definition |
Coverage parity vs. payment parity — key contrast:
Coverage parity prevents denial of benefits; it does not set a reimbursement rate. Payment parity sets a rate floor equal to in-person reimbursement. A state can have one without the other. Providers in states with coverage parity but no payment parity may receive lower rates for telehealth services even when the service cannot be denied.
Federal Mental Health Parity and Addiction Equity Act (MHPAEA):
The MHPAEA (29 U.S.C. § 1185a) prohibits plans from applying more restrictive financial requirements or treatment limitations to mental health or substance use disorder benefits than to medical/surgical benefits. When a plan applies stricter telehealth rules to behavioral health visits than to equivalent medical visits, MHPAEA may be implicated in addition to any state parity law. Enforcement is shared among the Departments of Labor, Health and Human Services, and Treasury under the joint MHPAEA implementing regulations (29 CFR Part 2590).
Regulatory floor vs. ceiling:
State parity laws set a minimum obligation on insurers. Plans may voluntarily offer telehealth benefits that exceed parity requirements — for example, covering audio-only visits even in states where the statute is silent. The existence of a parity floor does not cap insurer generosity. Refer to telehealth reimbursement rates and codes for coding and billing structure that interacts with these parity obligations.
