Yes: a nurse practitioner, physician assistant or physician can open a cash-pay telemedicine hormone practice in Missouri. The gating items are a written collaborative practice arrangement with a Missouri physician for every NP and PA (neither has independent practice), a full Missouri license for anyone treating a Missouri patient, telemedicine prescribing statutes rewritten effective August 28, 2026, and a separate Missouri Bureau of Narcotics and Dangerous Drugs registration on top of the DEA number. This is a 2026 planning summary, not legal advice; confirm every point with the Missouri State Board of Nursing, the Board of Registration for the Healing Arts, BNDD and counsel.
Missouri practice authority: who can run and own a telemedicine hormone practice
Nurse practitioners in Missouri
Missouri is a restricted practice state for APRNs. Under RSMo Section 334.104 an APRN who diagnoses, treats or prescribes does so under a written collaborative practice arrangement with a Missouri-licensed physician, with no pathway that ends in independence. Bills to free APRNs with roughly 2,000 documented collaborative hours from the arrangement were heard in 2026 (SB 1016, SB 979, HB 1636), as in prior sessions, but published records do not show any becoming law; do not plan around a change.
The arrangement is a detailed document. The statute and the joint rules (20 CSR 2200-4.200 and 20 CSR 2150-5.100) require the APRN to send at least 10 percent of charts to the collaborating physician every 14 days, the physician to review at least 20 percent of charts in which the APRN prescribes controlled substances, and the physician to be present at least once every two weeks for chart review and medical direction wherever the APRN treats acutely or chronically ill patients, which includes hormone management. Before practicing apart, the APRN must complete a documented month with the physician continuously present. A physician may collaborate with no more than six full-time-equivalent APRNs, PAs and assistant physicians combined; some read the nursing rule as applying a lower outpatient cap, so ask the Board.
Geographic proximity matters most to a telemedicine founder. Section 334.104 still requires the physician and APRN to maintain proximity, but expressly allows a waiver when the arrangement describes the use of telehealth as defined in Section 191.1145, and the boards may approve other waivers on application within 45 days. The joint rule that once defined proximity as 75 miles by road is reported to have been rescinded by both boards in 2024 as inconsistent with the statute; because secondary sources disagree on what replaced it, read the current rule text and ask both boards before signing with a distant physician.
For a hormone practice the controlled-substance detail is favorable. An arrangement may delegate Schedule III, IV and V drugs plus Schedule II hydrocodone, and the APRN must hold a Board of Nursing certificate of controlled substance prescriptive authority, which under Section 335.019 requires an advanced pharmacology course, 300 preceptorial prescribing hours and at least 1,000 hours of APRN practice. The 120-hour, no-refill limit applies to Schedule III narcotics and Schedule II hydrocodone; testosterone is a Schedule III non-narcotic, so that cap is not usually read to reach it, but the arrangement must name each controlled substance delegated. Confirm the reading with counsel.
Physician assistants in Missouri
Since 2019 Missouri PAs practice under a collaborative practice arrangement rather than supervision, governed by RSMo Section 334.735 and rule 20 CSR 2150-7.135. The mechanics mirror the APRN rules: 10 percent chart review every 14 days, 20 percent of controlled-substance charts, physician presence every two weeks in acute or chronic care, a documented period of continuous presence before practicing apart (read as one month; a 2025 proposed amendment would drop the fixed month, so check whether it was adopted) and the same six-FTE cap. The rule says telehealth may satisfy the presence requirement when patient consent is documented. Proximity for PAs is set by the Board of Registration for the Healing Arts rather than a statutory mileage; ask the Board for its current standard. PAs may be delegated Schedule III through V and Schedule II hydrocodone under Section 334.747, with their own DEA and BNDD registrations.
Physicians and the corporate practice of medicine
Missouri is usually listed among the states with a weak or lightly enforced corporate practice of medicine doctrine: no statute flatly bars a business corporation from employing physicians, and the Board of Registration for the Healing Arts has not pursued it the way boards in Texas, California or New York do. Still, Chapter 356 governs any professional corporation, fee-splitting rules in Chapter 334 apply, and a non-clinician who controls clinical decisions invites trouble. A physician starting a cash-pay hormone clinic typically owns the practice outright and, if outside capital or an operating partner is involved, places the non-clinical business in a management services organization under a fair-market-value agreement.
So who may own the practice?
A physician may own it outright. Under Chapter 356 a professional corporation may issue shares only to persons licensed to render a service its articles permit; registered nurses are a listed profession, so an NP can own a nursing professional corporation or, as many Missouri NPs do, an ordinary LLC through which the NP practices under a collaborative arrangement. Physician-nurse co-ownership of one professional corporation depends on certification by both licensing authorities under Section 356.041. Physician assistants are not on the Chapter 356 list, so PA ownership generally runs through an ordinary LLC or an MSO. Missouri has no PLLC statute; put the model in writing with counsel before filing.
Missouri telehealth rules for a remote hormone practice
Licensure and patient location. RSMo Section 191.1145 requires any provider treating a patient located in Missouri through telehealth to be fully licensed in Missouri; the only exceptions are informal uncompensated consultations, uncompensated emergency care and episodic consultation at a Missouri physician’s request. Missouri issues no telehealth-only license. The Interstate Medical Licensure Compact shortens the path for physicians licensed elsewhere. The Nurse Licensure Compact covers the RN license only; an APRN still needs a Missouri APRN license, a Missouri collaborating physician and the Board of Nursing’s controlled-substance certificate, and a PA needs a Missouri PA license and collaborating physician.
Establishing the relationship. Section 191.1145 defines telehealth to include audiovisual, audio-only and store-and-forward technology and holds the provider to the in-person standard of care. The relationship rules in Section 191.1146 and the prescribing rules in Section 334.108 were rewritten by the 2026 health-care omnibus (House Bill 2372), effective August 28, 2026. As amended, a physician may establish the relationship in person, by consulting another physician who already treats the patient, or by a telemedicine encounter when the standard of care does not require an in-person visit; the technology must support an informed diagnosis as though the evaluation were in person, and a physical examination is required only where the standard of care calls for one. Section 334.108 requires a valid relationship before anything is prescribed through telemedicine and limits prescribing on a telemedicine evaluation alone to physicians, their on-call designees and APRNs, PAs and assistant physicians in collaborative practice working within scope under an established, ongoing relationship. Read both sections in their August 2026 form with counsel.
Questionnaires. The 2026 amendments add guardrails for questionnaire-driven telehealth: the treating professional must review the questionnaire, it must elicit what an in-person evaluation would, the provider must be employed by or contracted with a business entity licensed to provide health care in Missouri, and a written report must go to the patient’s primary care provider within 14 days if the patient names one. A live video visit with lab review satisfies these easily; an asynchronous intake form must be built to them.
Informed consent. Missouri has no single telehealth consent statute, but the PA rule requires documented consent when telehealth is used, and a signed consent covering the technology, its limits, identity verification and emergency procedures is the sensible baseline for intake.
Controlled substances and registrations. Testosterone is Schedule III, so every prescriber needs a DEA registration tied to a Missouri practice address and, separately, a Missouri controlled substance registration from the Bureau of Narcotics and Dangerous Drugs within the Department of Health and Senior Services. BNDD registration is online only, personal to the registrant, required for each location, issued for up to 12 months and modestly priced (the published practitioner fee is $30). BNDD states it does not currently issue registrations to practitioners located outside Missouri; a founder treating Missouri patients from another state should ask BNDD how it handles a telehealth prescriber. Missouri’s statewide prescription drug monitoring program launched in December 2023; the statute imposes no general query mandate on prescribers (a federal rule covers Medicaid patients), but checking before every controlled prescription is sound practice. Section 195.550 has required electronic prescribing of Schedule II through IV since 2021, so an EHR with certified EPCS is non-negotiable. Federal telemedicine flexibilities for controlled substances are extended through December 31, 2026; confirm the federal position before the first prescription.

Entity options, registered agent and Missouri taxes
Missouri clinicians choose between an ordinary LLC under Chapter 347, filed online with the Secretary of State for about $50 with no annual report, and a professional corporation under Chapter 356, which needs a licensing-authority certificate before filing and files an annual registration report. An NP-owned business entity or an MSO is an ordinary LLC. Every Missouri entity needs a registered agent with a physical Missouri street address.
Missouri repealed its corporate franchise tax in 2016. The corporate income tax is a flat 4 percent, and pass-through income is taxed on the owner’s return at graduated rates topping out below 5 percent (most sources give 4.7 percent for 2026). The local item that surprises founders is the 1 percent earnings tax in Kansas City and St. Louis, which reaches wages and the net profits of businesses located in or doing business in either city; Kansas City voters renewed it in April 2026, and St. Louis adds a small payroll expense tax. A practice based elsewhere in Missouri generally avoids it. Treat these as typical figures to verify with a Missouri CPA.
Labs and pharmacy in Missouri
Missouri places no statutory restriction on direct-access laboratory testing of the kind found in New York or New Jersey; the national laboratories have offered patient-initiated testing in Missouri since 2016, and lab policies govern. In a cash-pay hormone model the clinic orders the panel under its own lab account, the patient visits a draw site in Kansas City, St. Louis, Springfield, Columbia or a rural county, and results flow into the EHR.
The pharmacy detail that trips up new practices is nonresident licensing. A pharmacy outside Missouri that ships to Missouri patients must hold a nonresident pharmacy license from the Missouri Board of Pharmacy under Chapter 338, renewed annually, backed by a current home-state license and, for compounders, a signed statement that it will follow Missouri’s sterile compounding rule (20 CSR 2220-2.200, which differs from USP 797). Missouri bars compounding copies of commercially available products and compounded office stock for human patients, so every compounded prescription, including injectable testosterone, must be patient-specific. Ask any compounder for its Missouri nonresident license number before routing the first prescription, and keep an in-state 503A backup.

Frequently asked questions
Can a nurse practitioner open a telemedicine hormone clinic in Missouri without a physician?
No. Missouri requires a written collaborative practice arrangement with a Missouri-licensed physician for any APRN who diagnoses, treats or prescribes, with 10 percent chart review every 14 days, 20 percent review of controlled-substance charts and physician presence every two weeks. An NP can own and run the business, and proximity can be waived when the arrangement describes telehealth use, but the physician and the review cadence are part of the model. Independence bills heard in 2026 have not become law as far as published records show; confirm with the Board of Nursing.
Does Missouri require an in-person visit before prescribing testosterone by telemedicine?
Not as a blanket rule. Sections 191.1146 and 334.108, as amended effective August 28, 2026, allow the relationship to be established by a telemedicine encounter when the standard of care does not require an in-person visit and require a physical examination only where the standard of care calls for one; a questionnaire that does not elicit what an in-person evaluation would is not enough. Testosterone is federally Schedule III, so federal telemedicine prescribing rules, extended through December 31, 2026, also apply.
Do I need a Missouri controlled-substance registration in addition to my DEA number?
Yes. Every prescriber of controlled substances to Missouri patients must hold a Bureau of Narcotics and Dangerous Drugs registration, applied for online by the registrant personally, for each practice location, renewed annually and matched to a DEA registration at a Missouri address. BNDD states it does not issue registrations to practitioners located outside Missouri, so an out-of-state founder should ask BNDD how to proceed. Electronic prescribing of controlled substances is mandatory.
Can I treat Missouri patients from another state?
Only with full Missouri authority. Section 191.1145 requires any provider treating a patient in Missouri by telehealth to hold a full Missouri license; there is no telehealth registration. An APRN needs a Missouri APRN license, collaborating physician and controlled-substance certificate; a PA needs a Missouri PA license and collaborating physician. Both also need a BNDD registration, which currently presumes a Missouri practice location.
