CPOM Compliance for Montana Healthcare Startups
Montana has no California-style standalone CPOM ban. The Professional Corporation Act still limits who may hold shares, and no one practices medicine before a license issues.

Montana CPOM is Nuanced. The state does not copy California Business and Professions Code § 2400. Official MCA 35-4-301 says a professional corporation may issue shares only to natural persons authorized to render a professional service permitted by the articles, to defined general partnerships, and to professional corporations authorized by Montana law to render that service. An issuance or transfer in violation is void. MCA 35-4-208 says no professional corporation, domestic or foreign, may begin rendering professional services until it files a copy of its articles with each licensing authority. MCA 37-3-301 says an applicant may not engage in the practice of medicine before a license issues, and it tells the Board to provide telemedicine guidelines by rule. Billings diligence still wants a physician-owned PC plus a fair-market-value MSA.
Do not read the absence of a California-style ban as permission for a lay operating company to practice medicine. If you elect a professional corporation under Title 35, chapter 4, the share rules apply. A medical-director title on a Montana marketing LLC does not put that LLC on the shareholder list in MCA 35-4-301. Foundry still recommends a physician-owned PC plus an FMV MSA for multi-state and venture-backed models that treat Montana patients.
MCA 35-4-205 says professional corporations may be organized under the chapter only to render professional services, and services ancillary to them, within a single profession, except where the licensing laws and rules actually permit a combination of professions or of professional and business purposes. Do not assume a med spa menu (medicine plus a retail brand) can sit inside one professional corporation because the storefront sells both. The medicine belongs in the professional entity the licensing rules allow. The brand and the non-clinical staff belong in the MSO.
MCA 35-4-301(1) is specific. Natural-person shareholders must be authorized by law of Montana or of another state, territory, or the District of Columbia to render a professional service the articles permit. A general-partnership shareholder needs every partner authorized to render such a service, and at least one partner authorized by Montana law. A professional-corporation shareholder must itself be authorized by Montana law to render that service. Subsection (2) lets the licensing authority further restrict share issuance to preserve ethical standards. Subsection (3) limits voluntary transfers and pledges to holders who could have received the shares directly. Subsection (5) voids a bad issuance or transfer. The operator default is a licensed physician shareholder. Do not park MSO equity, investor equity, or a management-company block on the professional corporation.
MCA 35-4-208 applies to domestic and foreign professional corporations. Filing articles with the licensing authority is a condition of beginning to render the professional service in Montana. The section also says the chapter does not limit the licensing authority's power over natural persons or over standards of professional conduct. Qualifying a foreign PC is not a shortcut around the Board, and it is not a 50-state network. The people who practice still answer to the Board. The entity still has to be allowed to render the service.
Medicine sits on top of the corporate statute. MCA 37-3-301(1) is a license-first rule: before being issued a license, an applicant may not engage in the practice of medicine in this state. Subsection (3), amended in 2025, says the Board shall provide guidelines by administrative rule for the practice of telemedicine by physicians. A virtual visit with a patient located in Montana is a Montana practice question, not a headquarters question. The Board of Medical Examiners publishes its administrative-rule index, including the physician and telemedicine chapters. Read the current rule before you treat "telemedicine guidelines" as a waiver of licensure.
ARM 24.156.405 is titled Unprofessional Conduct on the Secretary of State's rules gateway (reviewed 16 October 2026). The Board's published unprofessional-conduct text treats practice as the partner, agent, or employee of, or in joint venture with, a person who does not hold an equivalent license as unprofessional conduct. The same text does not prohibit incorporation of licensees as a professional service corporation under Title 35, chapter 4, a professional limited liability company under Title 35, chapter 8, or a professional limited liability partnership under Title 35, chapter 10. It also allows practice with a licensed health care facility or other licensed health care provider when a written agreement says the relationship may not affect independent judgment, the judgment in fact is not affected, and the licensee is not required to refer or act against the patient's interest. Register notices in 2025 and 2026 amended ARM 24.156.405. Confirm the current subsection with counsel before you rely on a downloaded PDF. ARM 24.156.625 has been repealed. As of this review, the rules gateway lists ARM 24.156.407 as an application-for-licensure rule, not the unprofessional-conduct rule.
Do not treat a Montana charter as a CPOM passport. CPOM follows the patient. If you treat Idaho, Wyoming, North Dakota, or South Dakota patients, those states control. If Utah patients are on the panel, Utah needs a domestic professional entity. See Utah CPOM. Foundry does not cover Utah, or any other state, with a plug-in PC network. Collaboration for physician assistants is a different job from owning the Professional Corporation. See collaborating physician vs physician PC owner. Aesthetics operators should also read the med spa hub.
Typical PC / MSO structure in Montana
When Montana patients or a Montana clinical entity are in scope, form a Montana professional corporation under Title 35, chapter 4, owned by persons MCA 35-4-301 allows, with a licensed physician as the operator default. File the articles with the Board before the PC renders services, as MCA 35-4-208 requires. The MSO provides non-clinical services under a written MSA at fair market value. Clinical revenue lands in the PC. Foundry forms that structure ($15,000) and matches a friendly PC owner ($3,000/mo). Not a rented Super PC.
If you also treat Idaho or North Dakota patients, Montana's Nuanced label does not control those states. Start with the CPOM 50-state guide. Neighboring Idaho and North Dakota have their own pages.
When you still need a PC vs only an MSO
Use the table as an operator rule, not a filing opinion. Confirm with counsel.
| Montana fact pattern | Typical entity | Why |
|---|---|---|
| Montana-only, cash-pay, physician already owns the practice | May stay on the existing professional corporation | Still document clinical control and FMV admin if an MSO is in the picture |
| Venture-backed or multi-state telehealth that includes Billings, Missoula, Bozeman, or Helena patients | Montana professional corporation + FMV MSA, plus the 35-4-208 filing | Buyers and payers test CPOM compliance the same way they do in strict states |
| Montana HQ with patients only in other states | Form for the patient states; a Montana HQ alone is not enough | CPOM follows the patient, not the HQ charter |
| Foreign PC offered as the Montana clinical entity | Still file articles with the licensing authority before rendering, and keep shares inside 35-4-301 | 35-4-208 names domestic and foreign professional corporations |
| Montana plus Idaho or North Dakota | Form for the neighboring states you treat, then the Montana PC if Montana patients are in scope | A Nuanced label does not soften Idaho Code § 54-1804 or N.D.C.C. chapter 10-31 |
Fee-splitting and funds-flow risk
Share rules plus the unprofessional-conduct overlay are what buyers still test. A percentage-of-collections management fee is the pattern that looks most like a split of professional fees and like de facto control of judgment, which is the fact ARM 24.156.405 cares about when a licensee practices inside someone else's venture. Prefer a fixed or FMV-supported admin fee. Pair Montana with the fee-risk table on CPOM compliance.
| Montana pattern | Risk | Safer pattern |
|---|---|---|
| Lay LLC holds itself out as practicing medicine | High: MCA 37-3-301 | Licensed physician ownership of the professional corporation |
| MSO paid a percentage of professional collections | High: diligence and judgment overlay | Fixed FMV admin fee with a memo |
| Lay equity, or shares outside MCA 35-4-301 | High: void issuance | Licensed physician shareholder. Partnership or PC holders only if they actually fit the statute |
| Licensee employed by an unlicensed person, with no written independent-judgment agreement | ARM 24.156.405 problem until counsel clears the facts | PC under Title 35, chapter 4, or a facility arrangement that meets the written-agreement conditions |
| Render services before the licensing-authority article filing | MCA 35-4-208 | File, then see patients |
| Cite the Montana charter as covering ID, WY, ND, or UT patients | Wrong read: CPOM follows the patient | Form for each patient state; Utah needs a domestic professional entity |
| Physician PC + FMV MSA + separate books | Base case | Revisit FMV when volume changes |
Board vs buyer / payer checks
Licensing boards discipline licensees. Buyers and payers run a different file. Use both columns. Full operating map: CPOM compliance.
| Who checks | What they sample | Montana fail signal |
|---|---|---|
| Montana Board of Medical Examiners | License under MCA 37-3-301; article filing under MCA 35-4-208; conduct under ARM 24.156.405 | Practice before licensure; MSO writing protocols; unlicensed holding-out |
| Buyer diligence | Shareholder ledger vs MCA 35-4-301; one claim from payer to PC bank to MSA invoice | MSO lockbox; percentage MSA; lay shares |
| Payer / credentialing | Claim TIN and group NPI on the physician-owned PC | Marketing MSO TIN on the claim |

Montana CPOM FAQ
Does Montana have CPOM?
Montana is Nuanced on the CPOM 50-state guide. There is no California B&P § 2400 analogue. MCA 35-4-301 still limits professional-corporation shares. MCA 37-3-301 still requires a license before practice. ARM 24.156.405 is the Board's unprofessional-conduct rule.
Do I still need an MSO-PC in Montana?
Yes for most venture-backed and multi-state models that treat Montana patients or use a Montana clinical entity. The professional entity holds clinical care; the MSO is paid fair market value for non-clinical services.
Can unlicensed owners hold a Montana professional corporation?
MCA 35-4-301 limits shares to authorized natural persons, defined partnerships, and professional corporations authorized in Montana. A lay operating company is outside that list. An issuance in violation is void. Confirm current text with counsel.
Does a Montana entity replace state-by-state CPOM?
No. CPOM follows the patient, not your Montana charter. Form for each patient state on the CPOM 50-state guide, including Idaho and North Dakota when those patients are on the panel. Utah patients need a domestic Utah professional entity.
How does Foundry help with Montana CPOM?
MSO-PC formation is $15,000 one-time. A licensed physician PC owner is $3,000/mo. Foundry is not a law firm.
