Three State Licenses, One MAC: Which Medicare Enrollment Applies

Summary

Medicare enrollment follows the practitioner's practice location, so a clinician licensed in three states who treats a Medicare patient sitting in another state still bills the single MAC for the state where the clinician physically works. CMS says plainly that enrollment in the state where the beneficiary resides is not required. Physically providing services inside a second state triggers a second CMS-855I, and state licensure stays a separate obligation the MAC does not verify.

Which MAC does a multi-state telehealth practice enroll with?

The MAC whose jurisdiction covers the place you physically work. CMS states it without qualification: you are not required to enroll in the state or states where the beneficiary resides 1Ref 1Centers for Medicare & Medicaid Services (2026).Understanding Telehealth and Teleradiology Enrollment.That a telehealth practitioner is not required to enroll in the state or states where the beneficiary resides; the worked scenario in which a Maryland solo practice's claims are processed by the Maryland MAC on the basis of the practice location; that MACs verify licensure only in the state where the provider is physically located; the four reassignment scenarios; and the home-practitioner rule that a clinician with a physical practice location enrolls and bills from it without reporting the home address, described as permanent policy in the 7/23/2026 revision.. Three licenses widen the set of patients you may lawfully treat. Medicare's contractor map is drawn around where the clinician sits, so the count of enrollments stays at one.

A MAC, a Medicare Administrative Contractor, is a private insurer awarded a geographic jurisdiction to process Medicare Part A and Part B enrollment applications and fee-for-service claims 2Ref 2Centers for Medicare & Medicaid Services (2024).Marriage and Family Therapists (MFTs) and Mental Health Counselors (MHCs) Provider Enrollment Frequently Asked Questions (FAQs).The definition of a MAC as a private insurer awarded a geographic jurisdiction to process Medicare Part A and Part B enrollment applications and fee-for-service claims, and that CMS publishes a designated-MAC lookup a practitioner can use to identify the contractor for an address.. That jurisdiction attaches to territory. A license attaches to a person, and the two were never built to line up one for one.

CMS works the case in its own enrollment guidance. A solo private practice in Maryland with no reassignment files with the Maryland MAC, and that MAC processes claims on the basis of the practice location 1Ref 1Centers for Medicare & Medicaid Services (2026).Understanding Telehealth and Teleradiology Enrollment.That a telehealth practitioner is not required to enroll in the state or states where the beneficiary resides; the worked scenario in which a Maryland solo practice's claims are processed by the Maryland MAC on the basis of the practice location; that MACs verify licensure only in the state where the provider is physically located; the four reassignment scenarios; and the home-practitioner rule that a clinician with a physical practice location enrolls and bills from it without reporting the home address, described as permanent policy in the 7/23/2026 revision.. The guidance carries a revision date of July 23, 2026, and it treats the home-address rule (a clinician who works from home need not report that address) as permanent policy rather than a flexibility waiting to expire.

Why extra licenses do not add enrollments

Because the trigger CMS wrote into the rule is the practitioner's own location. The Medicare Learning Network telehealth booklet states it in a line: a separate Medicare enrollment is required for each state where the practitioner provides services 3Ref 3Centers for Medicare & Medicaid Services (2025).Telehealth Services.That a separate Medicare enrollment is required for each state where the practitioner provides services, and that all distant site providers remain subject to state licensing requirements.. On an ordinary telehealth day the service is furnished from the room the clinician is sitting in, and the beneficiary's state never enters the test.

The application form carries the same rule in its instructions. The CMS-855I tells an applicant to report only those practice locations within the jurisdiction of the designated MAC receiving the application, and a location outside that jurisdiction takes its own CMS-855I filed with the MAC that holds it 4Ref 4Centers for Medicare & Medicaid Services (2026).Form CMS-855I — Medicare Enrollment Application: Physicians and Non-Physician Practitioners.The application's own instructions: report only practice locations within the jurisdiction of the designated MAC receiving the application, a location outside that jurisdiction requires a separate CMS-855I filed with that MAC, and Section 4B is completed for each practice location where services are rendered to Medicare beneficiaries, including distant sites where telehealth services are furnished.. Section 4B is completed for each practice location where services are rendered to Medicare beneficiaries, and CMS names any distant site, the place the practitioner occupies while the telehealth service happens, among them.

So the form has one field where this question is settled, and the field is an address.

What does trigger a second CMS-855I?

Physically performing services inside a second state. Rent a room across the border one week a month, keep a second office, or see anyone while sitting in that state, and that location falls outside your current MAC's jurisdiction and needs its own CMS-855I filed with the MAC that holds it 4Ref 4Centers for Medicare & Medicaid Services (2026).Form CMS-855I — Medicare Enrollment Application: Physicians and Non-Physician Practitioners.The application's own instructions: report only practice locations within the jurisdiction of the designated MAC receiving the application, a location outside that jurisdiction requires a separate CMS-855I filed with that MAC, and Section 4B is completed for each practice location where services are rendered to Medicare beneficiaries, including distant sites where telehealth services are furnished.. The licenses in your drawer never enter that test.

Reassignment is the other arrangement that moves the answer. CMS's telehealth enrollment guidance works through four scenarios, three of them turning on reassignment, so a practitioner who reassigns benefits to a group, or who is thinking about it, should read those before assuming the solo answer carries over 1Ref 1Centers for Medicare & Medicaid Services (2026).Understanding Telehealth and Teleradiology Enrollment.That a telehealth practitioner is not required to enroll in the state or states where the beneficiary resides; the worked scenario in which a Maryland solo practice's claims are processed by the Maryland MAC on the basis of the practice location; that MACs verify licensure only in the state where the provider is physically located; the four reassignment scenarios; and the home-practitioner rule that a clinician with a physical practice location enrolls and bills from it without reporting the home address, described as permanent policy in the 7/23/2026 revision.. A solo practice reassigning to nobody stays in the simple case for as long as it stays solo.

A second enrollment record is also where the next question starts: multiple PTANs, one NPI. That is worth settling before the first claim goes out rather than after the first remittance comes back looking wrong.

Licensure is a separate rail, and the MAC does not check it for you

Medicare enrollment answers who pays you. State licensure answers whether you may lawfully see the person at all, and enrollment does not touch it: all distant site providers are subject to state licensing requirements 3Ref 3Centers for Medicare & Medicaid Services (2025).Telehealth Services.That a separate Medicare enrollment is required for each state where the practitioner provides services, and that all distant site providers remain subject to state licensing requirements.. CMS's enrollment guidance is blunter about the division of labor. MACs only verify licensure in the state where the provider is physically located 1Ref 1Centers for Medicare & Medicaid Services (2026).Understanding Telehealth and Teleradiology Enrollment.That a telehealth practitioner is not required to enroll in the state or states where the beneficiary resides; the worked scenario in which a Maryland solo practice's claims are processed by the Maryland MAC on the basis of the practice location; that MACs verify licensure only in the state where the provider is physically located; the four reassignment scenarios; and the home-practitioner rule that a clinician with a physical practice location enrolls and bills from it without reporting the home address, described as permanent policy in the 7/23/2026 revision., which leaves every other state's rules sitting with you.

That is state licensure doing its ordinary work as the rule under everything. Your three licenses exist for three boards, and each board decides on its own terms whether a session with a person sitting inside its borders counts as practice there. CMS defers to state law on that question and does not resolve it for you, which is why the second and third licenses are worth their renewal fees even though Medicare never asks about them.

A compact, the interstate route to a license in a second state, changes how that license is obtained. It does not move the enrollment question, which still turns on the address reported in Section 4B 4Ref 4Centers for Medicare & Medicaid Services (2026).Form CMS-855I — Medicare Enrollment Application: Physicians and Non-Physician Practitioners.The application's own instructions: report only practice locations within the jurisdiction of the designated MAC receiving the application, a location outside that jurisdiction requires a separate CMS-855I filed with that MAC, and Section 4B is completed for each practice location where services are rendered to Medicare beneficiaries, including distant sites where telehealth services are furnished..

Where the Medicare patient may sit, and the date that changes it

Anywhere in the United States and territories, through December 31, 2027. That is the position in CMS's Telehealth FAQ as updated February 26, 2026, and it is the volatile half of this page 5Ref 5Centers for Medicare & Medicaid Services (2026).Telehealth FAQ.Where a Medicare beneficiary may be located to receive telehealth: anywhere in the United States and territories through December 31, 2027, and the change from January 1, 2028 under which, except for behavioral health services, the beneficiary generally must be in a medical facility in a rural area. Document updated 2026-02-26, the as-of date carried in the prose.. From January 1, 2028, except for behavioral health services, a beneficiary will generally need to be in a medical facility in a rural area for a Medicare telehealth service.

None of that changes which MAC holds your enrollment. Patient location is a coverage question and practice location is a jurisdiction question, and they are answered by different documents. But the coverage question is the one with a clock on it, so read the FAQ's own revision line before relying on any date repeated here.

Working from home: which address goes on the application

Your physical practice location, when you have one. CMS's telehealth enrollment guidance says a practitioner who furnishes telehealth from home while keeping a physical practice location can enroll and bill from that practice location as if the service was provided in person, and does not need to report the home address 1Ref 1Centers for Medicare & Medicaid Services (2026).Understanding Telehealth and Teleradiology Enrollment.That a telehealth practitioner is not required to enroll in the state or states where the beneficiary resides; the worked scenario in which a Maryland solo practice's claims are processed by the Maryland MAC on the basis of the practice location; that MACs verify licensure only in the state where the provider is physically located; the four reassignment scenarios; and the home-practitioner rule that a clinician with a physical practice location enrolls and bills from it without reporting the home address, described as permanent policy in the 7/23/2026 revision.. The guidance, revised July 23, 2026, presents that as permanent policy.

A practice with no office at all is a different arrangement, and the form answers it through the same field. Whatever address is reported as the practice location is the address that sets the jurisdiction, and it has to sit inside the jurisdiction of the MAC receiving the application 4Ref 4Centers for Medicare & Medicaid Services (2026).Form CMS-855I — Medicare Enrollment Application: Physicians and Non-Physician Practitioners.The application's own instructions: report only practice locations within the jurisdiction of the designated MAC receiving the application, a location outside that jurisdiction requires a separate CMS-855I filed with that MAC, and Section 4B is completed for each practice location where services are rendered to Medicare beneficiaries, including distant sites where telehealth services are furnished.. Get that one line right and the rest of the enrollment follows it.

Find your MAC, then work in this order

Start from the address you will report. CMS publishes a designated-MAC lookup, so answering which MAC processes my Medicare claims takes minutes 2Ref 2Centers for Medicare & Medicaid Services (2024).Marriage and Family Therapists (MFTs) and Mental Health Counselors (MHCs) Provider Enrollment Frequently Asked Questions (FAQs).The definition of a MAC as a private insurer awarded a geographic jurisdiction to process Medicare Part A and Part B enrollment applications and fee-for-service claims, and that CMS publishes a designated-MAC lookup a practitioner can use to identify the contractor for an address.. That answer decides where the CMS-855I goes, and it decides whose local coverage policies and billing articles you will be reading for as long as the practice keeps that address.

Four steps, in this order:

Settle the practice location you will report, including any distant site where telehealth services are rendered 4Ref 4Centers for Medicare & Medicaid Services (2026).Form CMS-855I — Medicare Enrollment Application: Physicians and Non-Physician Practitioners.The application's own instructions: report only practice locations within the jurisdiction of the designated MAC receiving the application, a location outside that jurisdiction requires a separate CMS-855I filed with that MAC, and Section 4B is completed for each practice location where services are rendered to Medicare beneficiaries, including distant sites where telehealth services are furnished..
Look up the designated MAC for that address 2Ref 2Centers for Medicare & Medicaid Services (2024).Marriage and Family Therapists (MFTs) and Mental Health Counselors (MHCs) Provider Enrollment Frequently Asked Questions (FAQs).The definition of a MAC as a private insurer awarded a geographic jurisdiction to process Medicare Part A and Part B enrollment applications and fee-for-service claims, and that CMS publishes a designated-MAC lookup a practitioner can use to identify the contractor for an address..
File one CMS-855I with that MAC, reporting only the locations inside its jurisdiction 4Ref 4Centers for Medicare & Medicaid Services (2026).Form CMS-855I — Medicare Enrollment Application: Physicians and Non-Physician Practitioners.The application's own instructions: report only practice locations within the jurisdiction of the designated MAC receiving the application, a location outside that jurisdiction requires a separate CMS-855I filed with that MAC, and Section 4B is completed for each practice location where services are rendered to Medicare beneficiaries, including distant sites where telehealth services are furnished..
Confirm each state board's position on treating a person located in its state, since the MAC verifies licensure only where you physically are 1Ref 1Centers for Medicare & Medicaid Services (2026).Understanding Telehealth and Teleradiology Enrollment.That a telehealth practitioner is not required to enroll in the state or states where the beneficiary resides; the worked scenario in which a Maryland solo practice's claims are processed by the Maryland MAC on the basis of the practice location; that MACs verify licensure only in the state where the provider is physically located; the four reassignment scenarios; and the home-practitioner rule that a clinician with a physical practice location enrolls and bills from it without reporting the home address, described as permanent policy in the 7/23/2026 revision..

Commercial payers do not follow this map. Credentialing, enrollment, contracting run on each payer's own footprint and its own network by state, so a settled Medicare answer settles Medicare. Medicare Advantage is not answered here either: the documents cited are Part A and Part B fee-for-service guidance, and a plan's rules for an out-of-state telehealth member live in the plan's own contract.

One question is left over once the MAC is settled, and that is your status inside the enrollment: participation, non-par, opt-out. It is a separate decision with its own arithmetic, and it stays yours to make.

Common questions

No. Medicare requires a separate enrollment for each state where the practitioner provides services, and a telehealth service is furnished from wherever the clinician is sitting. Holding licenses in three states while working from one address leaves you with one enrollment and one MAC. CMS states directly that enrollment in the state where the beneficiary resides is not required.

The enrollment does not change, because it follows your practice location. The licensure question does change, and it is the one that can stop the visit. Each board decides whether treating a person located inside its state counts as practice there, and the MAC verifies licensure only in the state where you are physically located, so nobody checks this for you.

When you render services from a location outside your current MAC's jurisdiction, such as a second office or a rented room in another state. The form's instructions limit an application to practice locations inside the jurisdiction of the MAC receiving it, so an out-of-jurisdiction location takes its own application filed with the MAC that holds it. Reassignment to a group raises the same question.

If you keep a physical practice location, CMS says you can enroll and bill from it as if the service happened in person, and you do not need to report your home address. Without any office, the address you report as the practice location is what sets the jurisdiction, and it has to sit inside the jurisdiction of the MAC receiving the application.

Anywhere in the United States and territories through December 31, 2027, per CMS's Telehealth FAQ as updated February 26, 2026. From January 1, 2028, except for behavioral health services, the patient will generally need to be in a medical facility in a rural area. That is coverage rather than enrollment, and it carries a date, so check the current version.

No. The guidance behind this page is Part A and Part B fee-for-service enrollment policy. A Medicare Advantage plan's rules for an out-of-state telehealth member sit in that plan's own contract, and commercial payers run their own state-by-state networks. Settle Medicare first, then read each contract, because none of the guidance cited here speaks for them.
