Telehealth Medicare Coverage and Billing Guidelines

Medicare's telehealth rules are a moving target in the best possible way — the program has expanded access more in the past five years than in the previous two decades combined. This page covers which services Medicare covers via telehealth, how billing works for both providers and patients, what waivers and permanent rules are currently in effect, and where the coverage edges are. Whether the question involves originating sites, synchronous vs. asynchronous modalities, or the difference between a 99213 and a G0425, the answers are here.

Definition and scope

Medicare telehealth coverage is a federally defined benefit administered under telehealth policy and regulation frameworks that govern what services count, who can deliver them, and where patients must be located. Unlike commercial insurance, Medicare does not simply mirror in-person benefits for virtual visits — it operates from an enumerated list of approved services published by the Centers for Medicare & Medicaid Services (CMS) each calendar year.

Before the COVID-19 public health emergency, Medicare covered fewer than 100 telehealth services and required patients to be in rural, Health Professional Shortage Areas (HPSAs). The Consolidated Appropriations Act of 2023 extended most public health emergency waivers through December 31, 2024, and CMS has made a subset of those expansions permanent. The 2024 Medicare Physician Fee Schedule final rule added 15 services to the permanent telehealth list, bringing the total to over 250 covered codes (CMS Medicare Telemedicine Fact Sheet).

The benefit applies to Part B, which covers outpatient services. Part A (inpatient hospital) has separate, narrower provisions. Part C (Medicare Advantage) plans may offer additional telehealth benefits beyond the base Part B structure, and Part D does not directly govern telehealth delivery.

How it works

Medicare telehealth billing follows a defined sequence of requirements. A provider must be enrolled in Medicare, the patient must be a Medicare beneficiary, and the service must appear on CMS's approved telehealth services list. The visit must be delivered via an interactive audio-video system — meaning real-time, two-way communication — unless the service is classified as audio-only, which has its own narrower set of qualifying codes.

The billing structure works like this:

1. Service identification — The provider selects the appropriate CPT or HCPCS code matching the service delivered.
2. Place of Service (POS) code — Telehealth services delivered to a patient at home use POS 10; services delivered to a patient at a clinical originating site use POS 02.
3. Modifier attachment — The modifier 95 is appended to indicate synchronous telehealth delivery; modifier GT was historically used and is now largely replaced by 95 in most contexts.
4. Originating site billing — If the patient is physically located at a covered facility (a Federally Qualified Health Center, for example), that facility may separately bill HCPCS code Q3014 for the originating site facility fee.
5. Reimbursement rate — CMS reimburses most telehealth visits at the same rate as equivalent in-person visits, though some audio-only codes carry different relative value units.

For a deeper look at how codes translate to payment, telehealth billing and coding and telehealth reimbursement rates cover the numerical specifics.

Remote patient monitoring operates under a related but distinct billing pathway — codes 99453, 99454, 99457, and 99458 — and does not require real-time interaction, making it a different reimbursement category from standard telehealth.

Common scenarios

The broadest category of Medicare telehealth use involves mental health telehealth. Since 2023, Medicare has permanently removed the geographic restriction for mental health services specifically, allowing any Medicare beneficiary to receive behavioral health visits from home — but only after an in-person visit with the same provider within the prior 12 months. That in-person requirement is a meaningful operational constraint for practices.

Primary care visits represent the second major cluster. Office or outpatient evaluation and management codes (99202–99215) are fully covered via telehealth. A 99214 visit, typically a moderate-complexity problem, reimburses at approximately $130–$160 nationally under the 2024 fee schedule, depending on geographic payment locality. Providers billing these codes via telehealth follow the same documentation standards as in-person: history, examination notation (or its virtual equivalent), and medical decision-making or total time.

Chronic disease telehealth management frequently uses the Chronic Care Management (CCM) codes — 99490, 99491, 99487 — which do not require a face-to-face visit component and can be billed monthly based on clinical staff time. These sit adjacent to telehealth billing but are sometimes conflated with it.

Decision boundaries

The sharpest line in Medicare telehealth policy is the distinction between covered telehealth services and virtual communication services. A covered telehealth service replicates a face-to-face encounter and is billed with a standard POS and modifier. Virtual communication services — brief check-ins, e-visits, and remote evaluation of patient-submitted images — use a separate code set (G2012, G2010, 99421–99423) and carry lower reimbursement ceilings.

A second boundary separates store-and-forward telehealth from synchronous visits. Medicare covers store-and-forward only in Alaska and Hawaii under a federal demonstration project, per the statutory restriction at 42 U.S.C. § 1395m(m). Every other state must use real-time, interactive technology for a service to qualify as a reimbursable telehealth encounter under Part B.

Telehealth for rural communities occupies a different corner of the map: the geographic and originating site restrictions that still apply to non-mental-health services continue to favor rural HPSAs and certain facility types over urban home-based access — a distinction that directly affects which patients can access the benefit and how providers plan their service models. The telehealth vs. in-person care question, for Medicare purposes, often comes down not to clinical preference but to what the billing rules will actually support for a given code on a given day.
