Telehealth Reimbursement: Medicare POS 10 vs. POS 02, Modifiers 95 and 93, and State Coverage vs. Payment Parity Laws

Telehealth reimbursement is the regulatory and healthcare revenue cycle management (RCM) framework governing how Medicare, State Medicaid programs, and commercial health insurers adjudicate and pay for clinical encounters delivered remotely via synchronous audio-video platforms, synchronous audio-only telephone calls, and asynchronous store-and-forward technologies. Unlike standard in-person outpatient claims (`POS 11`), accurate telehealth claim adjudication requires aligning four interdependent coding and policy elements: the eligible CPT/HCPCS service code, the Place of Service (POS) code (`POS 10` vs. `POS 02`), the telemedicine modality modifier (`Modifier 95`, `Modifier 93`, or `FQ`), and the governing federal or state parity jurisdiction.

How Does Telehealth Reimbursement Work? Core Billing Mechanics

When a distant-site physician or non-physician practitioner (NPP) conducts a virtual visit over a telehealth platform, professional fee reimbursement is calculated from the interaction between the patient’s physical location at the time of service (the originating site) and the provider’s clinical service code.

1. Place of Service (POS) Codes: POS 10 vs. POS 02 and the Facility/Non-Facility Differential

Under the Centers for Medicare & Medicaid Services (CMS) Medicare Physician Fee Schedule (MPFS) rules, professional claims (`ASC X12N 837P` / `CMS-1500` Item 24B) must distinguish between two telehealth Place of Service codes based on where the patient is physically situated during the encounter:

POS Code	Official CMS Descriptor	Patient Location (Originating Site)	Medicare Physician Fee Schedule (MPFS) Rate
POS 10	Telehealth Provided in Patient’s Home	The patient is located in their private residence or home setting during the virtual encounter.	Reimbursed at the higher Non-Facility (Office) Rate, which includes full Practice Expense (PE) relative value units (RVUs) equivalent to an in-person `POS 11` clinic visit.
POS 02	Telehealth Provided Other than in Patient’s Home	The patient is located in a clinical facility, hospital outpatient department, rural health clinic, or skilled nursing facility (not their home).	Reimbursed at the lower Facility Rate, because the originating healthcare facility separately incurs the physical overhead (and may bill the originating site facility fee, `HCPCS Q3014`, when eligible).

2. Telehealth Modifiers: Modifier 95, Modifier 93, FQ, and GT

Alongside the POS code, payers require a CPT or HCPCS modifier in `CMS-1500` Item 24D to specify the technological modality used:

• Modifier 95 (Synchronous Telemedicine Service Rendered via a Real-Time Interactive Audio and Video Telecommunications System): Appended to CPT Appendix P approved codes (such as office/outpatient Evaluation and Management codes 99202–99215, Transitional Care Management 99495–99496, and psychotherapy codes) when delivered via two-way real-time audio-video technology.
• Modifier 93 (Synchronous Telemedicine Service Rendered via Telephone or Other Real-Time Interactive Audio-Only Telecommunications System): Appended to AMA CPT Appendix T codes when delivered via real-time two-way audio-only communication. Under CMS Medicare rules, two-way interactive audio-only telecommunication is permitted for telehealth services furnished to a beneficiary in their home if the distant-site practitioner has technical audio-video capability but the patient is not capable of, or does not consent to, the use of video technology.
• Modifier FQ (CMS Behavioral Health Audio-Only): Appended on Medicare claims for mental health and substance use disorder telehealth services furnished using audio-only communication technology.
• Modifier GQ and Legacy Modifier GT: Modifier GQ designates asynchronous store-and-forward telecommunications in federal demonstration programs (such as Alaska and Hawaii), while legacy Modifier GT is retained primarily on institutional Critical Access Hospital (CAH) Method II claims (`837I`) and specific state Medicaid fee schedules.

Medicare Telehealth Rules (42 CFR § 410.78) vs. Non-Telehealth Virtual Care

In federal compliance and clinical research billing, CMS strictly separates statutory Medicare Telehealth Services governed by Section 1834(m) of the Social Security Act (`42 CFR § 410.78`) from **Communications-Based Technology Services (CBTS)** and remote monitoring codes that are not subject to Section 1834(m) originating-site or geographic restrictions:

• Section 1834(m) Medicare Telehealth Services: Substitute for an in-person E/M or consultation visit and are listed on the annual CMS Medicare Telehealth Services List (categorized as Permanent or Provisional). Behavioral and mental health telehealth services have permanent statutory authority to be furnished to patients in their homes nationwide (subject to periodic in-person visit rules and exceptions), whereas non-behavioral medical telehealth flexibilities (waiving rural geographic and originating-site restrictions) are governed by congressional statutory extensions under Section 1834(m).
• Remote Physiologic Monitoring (RPM) and Remote Therapeutic Monitoring (RTM): Services such as Patient Remote Monitoring (RPM) (`CPT 99453, 99454`, and CPT 99457 / 99458) and RTM (`CPT 98975–98981`) are classified by CMS as E/M care management services rather than Section 1834(m) telehealth visits; they do not use `POS 02/10` or `Modifier 95` and are billed under the supervising practitioner’s standard office POS (`POS 11`).
• Brief Virtual Check-Ins and Online Digital E/M (e-Visits): Brief 5–10 minute check-ins (`HCPCS G2012`, `G2252`), interprofessional e-consults (`CPT 99446–99452`), and asynchronous patient-initiated portal e-visits over a 7-day cumulative period (`CPT 99421–99423`) are likewise distinct CBTS codes outside the Section 1834(m) telehealth list.

Telehealth Parity Laws by State: Coverage Parity vs. Payment Parity

For commercial health plans, health maintenance organizations (HMOs), and state-regulated insurance products, reimbursement is governed by state telehealth parity laws. However, healthcare compliance officers must distinguish between three legal layers:

Parity Dimension	Legal Definition & Payer Obligation	Reimbursement & Contracting Impact
Telehealth Coverage Parity (Service Parity)	Mandates that a state-regulated commercial insurer must cover a healthcare service delivered via telehealth if the plan covers that same service when delivered in person (provided the remote delivery meets the clinical standard of care).	Prohibits payers from blanket-denying virtual visits as “non-covered,” but does not prevent the payer from setting a lower fee schedule rate for telehealth than for in-person care unless payment parity also applies.
Telehealth Payment Parity (Reimbursement Parity)	Mandates that a state-regulated commercial insurer must reimburse providers for covered telehealth services at the same monetary rate (or on the same basis) as the equivalent in-person service.	Guarantees 100% fee-schedule parity between virtual and in-person visits (sometimes restricted by state statute to behavioral health, primary care, or network providers without negotiated virtual-only contracts).
ERISA Preemption (Self-Funded Employer Plans)	Under the federal Employee Retirement Income Security Act of 1974 (ERISA, 29 U.S.C. § 1144), self-insured employer health plans are regulated by the U.S. Department of Labor and are exempt from state insurance parity mandates.	Even in a state with strict payment parity laws, a self-funded ERISA plan may set its own telehealth coverage rules, cost-sharing, or discounted fee schedules.

Frequently Asked Questions

How does telehealth reimbursement work?

Telehealth reimbursement works by billing an eligible CPT or HCPCS clinical service code paired with a Place of Service code indicating the patient’s physical location (POS 10 for the patient’s home or POS 02 for another facility) and a modality modifier indicating the technology used (Modifier 95 for live audio-video or Modifier 93 / FQ for live audio-only). Payers then adjudicate the claim according to Medicare Physician Fee Schedule non-facility/facility rates, Medicaid state plan rules, or commercial coverage and payment parity contracts.

What is the difference between payment parity and coverage parity in telehealth?

Coverage parity requires a health insurer to cover a medical service via telehealth if it covers the same service in person. Payment parity goes a step further by requiring the insurer to pay the healthcare provider the exact same dollar reimbursement rate for the telehealth visit as it pays for an in-person office visit.

When is audio-only telehealth reimbursed by Medicare?

Medicare reimburses synchronous audio-only telehealth (billed with Modifier 93 or Modifier FQ) for approved behavioral health and counseling services, and for designated evaluation and management services furnished to a patient in their home (POS 10) when the clinician has two-way audio-video capability available, but the patient is unable to use or does not consent to video technology, and those circumstances are documented in the medical record.
