Telestroke and teleneurology billing follows a Medicare rule that most telehealth doesn’t get. Since 2019, acute stroke care by video has been exempt from the rural location and site requirements that limit other telehealth. A neurologist at a hub hospital can evaluate a patient in a suburban emergency department two states away, append modifier G0, and get paid. Whether that claim can go out at all usually depends on credentialing. The neurologist needs a license in the patient’s state, privileges at the spoke hospital, and enrollment with that patient’s plan before the first stroke alert.
Key Takeaways
- Medicare exempts acute stroke telehealth from geographic and originating site restrictions, and those claims carry modifier G0.
- The neurologist’s role, not the diagnosis, decides whether a telestroke encounter is billed as critical care, a telehealth consultation, or an interprofessional consult.
- Medicare’s broader telehealth flexibilities for non-stroke teleneurology visits now run through December 31, 2027.
- Medicare uses POS 02 or 10 instead of modifier 95, but many commercial and Medicaid plans still require 95.
- Credentialing by proxy lets a spoke hospital rely on the hub’s privileging decisions, but state licensure and payer enrollment still have to be done separately.
How Medicare Pays for Telestroke
The Bipartisan Budget Act of 2018 removed the geographic and originating site limits for telehealth used to diagnose, evaluate, or treat an acute stroke, starting January 1, 2019. The patient doesn’t have to be in a rural area or a health professional shortage area, and mobile stroke units count as originating sites.
The distant site neurologist reports the service with POS 02 and modifier G0. The spoke hospital bills its originating site facility fee with HCPCS Q3014, also with G0. The modifier applies to the acute stroke workup only. A follow-up visit a week later for blood pressure control or rehab planning is ordinary telehealth and doesn’t get G0.
While Medicare’s general telehealth flexibilities stay in force, the stroke exception matters less day to day. It becomes the only way to bill a non-rural telestroke consult if those flexibilities lapse, so the modifier belongs on every acute stroke claim now.
Coding the Telestroke Consult
The code depends on what the neurologist did. A tele-neurologist who directly evaluates a critically ill patient and personally manages the decision on thrombolysis or thrombectomy can bill critical care. That’s 99291 for the first 30 to 74 minutes and 99292 for each additional 30 minutes, which Medicare counts from minute 104. The note has to show the time, the critical illness, and the neurologist’s own management decisions.
When the neurologist advises and the emergency physician or intensivist keeps the decisions, the service is a consultation. Medicare doesn’t pay the CPT consultation codes, so it uses telehealth G codes instead. G0508 and G0509 cover initial and subsequent critical care consultations, and G0425 through G0427 cover emergency department or initial inpatient consultations of about 30, 50, and 70 minutes. Commercial plans vary, and some still want CPT consultation or emergency department E/M codes.
Some telestroke calls never include the patient. If the neurologist reviews the CT angiogram and advises the emergency physician by phone, that’s an interprofessional consult, billed as 99446 through 99449 for a verbal and written opinion or 99451 for a written report after five or more minutes of review. Medicare requires documented patient consent for these. Our post on which CPT codes are used in telestroke and teleneurology billing covers more code-level examples.
Teleneurology Visits Beyond Stroke
Most teleneurology is routine outpatient care, such as epilepsy follow-ups, headache management, and movement disorder visits. These bill with the office E/M codes 99202 through 99215. For Medicare, POS 10 means the patient was at home and POS 02 means they were somewhere else, and modifier 95 isn’t required. Many commercial and Medicaid plans still require 95, so the payer’s own policy decides.
Audio-only visits use the same E/M codes with modifier 93 when the patient can’t or won’t use video, and the note should say why. CPT deleted the telephone codes 99441 through 99443 in 2025. Medicare also doesn’t pay the newer telemedicine E/M codes 98000 through 98015, so a claim with those codes gets denied. A brief virtual check-in bills as 98016.
The Consolidated Appropriations Act, 2026 extended Medicare’s telehealth flexibilities through December 31, 2027, including home visits with no geographic limit. Starting in 2026, Medicare also lifted the telehealth frequency limits on subsequent hospital visits, 99231 through 99233, which helps neurologists who follow inpatients by video. Our telehealth billing page covers the general rules. Remote EEG and other diagnostic testing are covered on our neurology billing page.
Hub-and-Spoke Contracts and Who Bills
Most telestroke programs run under a contract between a hub (a stroke center or a teleneurology group) and the spoke hospitals it covers. Some spoke hospitals pay a monthly coverage fee and let the neurologists bill their professional services. Others pay per consult, and the neurologists don’t bill the patient’s insurance at all. If the contract doesn’t say which model applies, the same consult can end up paid twice, once by the hospital and once by the payer.
The spoke hospital’s own physicians bill separately. The emergency physician who calls the stroke alert reports their own E/M, as our emergency medicine billing page explains, and both claims can be paid when each physician’s work is distinct. Payments under these contracts also need to reflect fair market value, since a hospital paying a referring neurology group raises Stark and Anti-Kickback questions.
Where Telestroke and Teleneurology Claims Get Denied
The usual causes are mechanical. These include acute stroke claims sent without G0, the wrong POS for the patient’s location, CPT consultation codes sent to Medicare, deleted telephone codes still in the charge master, and commercial claims missing modifier 95. Critical care claims get denied when the note shows a consult role or leaves out the time. A neurologist who isn’t enrolled with the patient’s state Medicaid program or commercial plan will see every claim for that patient denied, no matter how well it was coded. Our denial management process sorts these by cause and fixes the coding or enrollment gap behind them.
Telestroke and Teleneurology Credentialing
State licensure
A tele-neurologist needs a license in the state where the patient is located, not just where the neurologist sits. A stroke network that crosses state lines can mean five or six licenses per neurologist. The Interstate Medical Licensure Compact speeds this up for physicians who qualify, though each state still issues and renews its own license.
Hospital privileges and credentialing by proxy
Each spoke hospital has to grant privileges before the neurologist can consult on its patients. CMS hospital rules let a spoke hospital rely on the hub hospital’s credentialing and privileging decisions under a written agreement, and the Joint Commission accepts the same approach. The spoke still approves privileges through its own medical staff process, and it shares quality data with the hub so the neurologist’s file stays current at reappointment.
Payer enrollment
Tele-neurologists enroll in Medicare and reassign their benefits to the group that bills for them. A neurologist who works only from home can list that address in PECOS as a home office for telehealth use, which keeps it off public directories. Every state Medicaid program in the network needs its own enrollment, out-of-state providers included, and each commercial plan credentials separately. Until each enrollment is approved, that neurologist’s claims for those patients can’t go out, which is why you can’t bill what you can’t credential.
Payer Contracting for Teleneurology
State telehealth laws differ on parity. Some states require plans to pay the same for telehealth as for in-person care, and others require only coverage. A teleneurology contract should spell out the telehealth rate, the modifier and POS the plan expects, whether it pays G0508 and G0509 or wants CPT codes, and whether it covers interprofessional consults. Payer contracting for a telestroke group also means checking that every plan in each spoke hospital’s market has the group in network.
Telestroke and Teleneurology Billing FAQ
What is the G0 modifier?
G0 marks a telehealth service used to diagnose, evaluate, or treat an acute stroke. It goes on the neurologist’s claim and the originating site’s Q3014 facility fee, and it exempts the service from Medicare’s geographic and originating site limits.
Does Medicare still limit telestroke to rural hospitals?
No. Acute stroke telehealth has been exempt from the rural requirement since January 1, 2019. Other Medicare telehealth also has no geographic limit through December 31, 2027.
Can a tele-neurologist bill critical care?
Yes, when the patient is critically ill and the neurologist personally manages the condition over video. The note must document the time and the neurologist’s own decisions. If the neurologist only advises the treating physician, the service is a consultation.
Which place of service code is used for teleneurology?
For Medicare, POS 10 when the patient is at home and POS 02 when the patient is anywhere else, including a hospital. Commercial and Medicaid plans may also require modifier 95.
Can spoke hospitals credential tele-neurologists by proxy?
Yes. CMS and the Joint Commission let a spoke hospital rely on the hub hospital’s credentialing decisions under a written agreement. Licensure in the patient’s state and payer enrollment still have to be completed separately.
How many state licenses does a tele-neurologist need?
One for every state where their patients are located. A network covering hospitals in four states means four licenses, and the Interstate Medical Licensure Compact can shorten the process for physicians who qualify. Payer enrollment through Medwave averages 85 days, so licensing should start first.
How Medwave Supports Telestroke and Teleneurology Programs
Telestroke billing goes wrong in small ways, like a missing G0, a consult coded as critical care, or the wrong POS for a home visit. Medwave codes each encounter to the neurologist’s documented role and sets POS and modifiers payer by payer, which keeps telestroke billing at a 98% clean claim rate.
On the credentialing side, we track state licenses, coordinate privileges at each spoke hospital, and enroll neurologists with Medicare, each Medicaid program in the network, and commercial plans. Payer enrollment runs about 85 days on average.
