Michigan collaborating physician requirements apply to a reduced-practice state with one of the most structurally distinct frameworks in the country. Michigan does not require a physician agreement for all APRN practice. NPs, CNMs, and CNSs in Michigan may independently prescribe nonscheduled (non-controlled) prescription drugs without any physician delegation, authorization, or agreement. What Michigan does require physician involvement for is controlled substance prescribing specifically, and that involvement takes the form of a written authorization issued by the supervising physician.
For physicians entering collaboration roles in Michigan, understanding exactly what requires physician delegation and what does not is essential before signing anything. The oversight structure Michigan uses differs meaningfully from the collaborative practice agreement models used in most other states. This guide covers every requirement a physician needs to understand in 2026, sourced directly from Michigan’s Public Health Code and administrative rules.
Michigan Collaborating Physician Overview: Where Michigan Stands
Michigan places NPs and CNMs in the reduced-practice category for controlled substance prescribing. The state operates a hybrid model: APRNs have substantial independent authority for non-controlled prescribing, but physician delegation through a written authorization is required before an APRN may prescribe any controlled substance.
Governing Bodies
Two regulatory bodies govern APRN practice and physician delegation in Michigan:
- Michigan Board of Nursing: Governs NP certification, specialty certification requirements, APRN scope of practice, and related administrative rules under MCL § 333.17201 through § 333.17242.
- Michigan Board of Medicine: Governs physician licensure, delegation authority, controlled substance prescribing through written authorization, and disciplinary matters under MCL § 333.17001 through § 333.17084.
Administrative Code Rule 338.2411 issued by the Michigan Board of Medicine defines what constitutes adequate supervision for physicians in collaborative APRN arrangements, including the conditions for continuous communication availability and periodic review.
The 2025 to 2026 Legislative Context
House Bill 4399, introduced in 2025, proposes to expand NP scope of practice to allow nurse practitioners to prescribe controlled substances in Schedules 2 through 5 without physician delegation. The H-1 substitute version, analyzed in November 2025, would also allow NPs to receive delegation from a qualified delegating practitioner that could include not only physicians but also experienced APRNs. As of the publication date of this guide, HB 4399 has not been enacted. The current framework under MCL § 333.17211a, which requires physician delegation for all controlled substance prescribing by NPs, remains in effect.
Michigan’s Unique Framework: Two Separate Tracks of APRN Practice
Michigan’s structure is not simply a modified version of a standard collaborative practice agreement state. It creates two genuinely distinct categories of APRN prescribing.
Track 1: Independent Non-Controlled Prescribing
Under MCL § 333.17211a(1)(a), an NP or CNM may independently prescribe nonscheduled prescription drugs without any physician delegation. This authority exists by statute and does not require a written authorization, a collaborative agreement, or any physician involvement. Michigan NPs can diagnose patients and prescribe the full range of legend drugs, including most common medications for hypertension, diabetes, infections, mental health conditions, and chronic disease management, completely independently. No physician involvement is required for non-controlled prescribing in any clinical setting.
Track 2: Controlled Substance Prescribing Through Written Authorization
Under MCL § 333.17211a(1)(b), an NP or CNM may prescribe controlled substances in Schedules 2 through 5 only as a delegated act of a physician. This delegation must be formalized in a written authorization that meets specific statutory requirements. Without a valid written authorization from a supervising physician, the NP has no legal basis for prescribing any controlled substance in any schedule.
The Written Authorization: Michigan’s Core Collaboration Document
The written authorization is defined under MCL § 333.17708(2)(i) and the administrative rules governing physician delegation. It is the instrument through which the physician formally delegates controlled substance prescribing authority to an NP or CNM. The written authorization must be in place before any controlled substance prescription is written by the APRN.
Filing and Retention
The written authorization is not filed with any state board before practice begins. Under MCL § 333.17708, the supervising physician must maintain the written authorization at the supervising physician’s primary place of practice. A copy must be provided to the NP. The Michigan Department of Licensing and Regulatory Affairs may request to review the written authorization at any time. Neither the Board of Nursing nor the Board of Medicine requires pre-approval of the authorization before controlled substance prescribing begins.
What Must Be in a Michigan Written Authorization
Under Michigan Administrative Code Rule 338.2411 and the prescriptive authority provisions of the Public Health Code, a valid written authorization must contain all of the following:
1. Physician and APRN Identification
The written authorization must include the name, license number, and signature of the supervising physician and the name, license number, and signature of the NP or CNM receiving the delegation.
2. Limitations or Exceptions to the Delegation
The authorization must state any limitations or exceptions that apply to the controlled substance prescribing being delegated. If the physician does not want to authorize certain schedules or drug categories, those exclusions must be explicitly stated. Silence on a drug class is not equivalent to exclusion.
3. Effective Date
The authorization must include an effective date. The delegation becomes operative on the effective date stated in the document.
4. Annual Review
Under MCL § 333.17708, the supervising physician must review and update the written authorization on an annual basis from the original date or the date of any amendment. The physician must note the review date and the method of review as part of the authorization record. An authorization that has passed the one-year mark without a documented annual review is not current.
Physician Eligibility and the Supervision Standard
A Michigan supervising physician must hold a current, active Michigan medical license in good standing with the clinical knowledge relevant to the controlled substances being delegated.
The Supervision Standard Under Michigan Administrative Code
Under Michigan Administrative Code Rule 338.2411, physician supervision that satisfies the delegation requirement must include all of the following:
- Continuous availability for consultation. The physician must be continuously available, either in person or by telecommunications, to the APRN for consultation throughout the period of the authorization.
- Periodic review. The physician must conduct periodic review of the services provided by the APRN under the written authorization. The frequency is not numerically specified but must be consistent with sound medical practice and the scope of the delegation.
- Predetermined procedures and drug protocols. Adequate supervision requires that predetermined procedures and drug protocols are established and available to guide the APRN’s prescribing.
No Geographic Proximity Requirement
Michigan does not impose a geographic proximity requirement on supervising physicians. Remote collaboration is fully permitted. A physician in Detroit can issue a written authorization to an NP practicing in the Upper Peninsula without any distance restriction. What Michigan requires is continuous availability by telecommunications, not physical proximity.
No Ratio Limit
Michigan does not impose a statutory cap on the number of NPs or CNMs a physician may supervise under written authorizations simultaneously.
Independent APRN Prescribing: What Does Not Require Delegation
Because Michigan’s framework allows substantial independent NP practice, it is important for physicians to understand what falls within the independent track before evaluating what the written authorization needs to cover.
What NPs Can Do Without a Physician
Michigan APRNs may independently, without any physician delegation:
- Diagnose patients within their specialty certification area
- Order and interpret laboratory and diagnostic tests
- Prescribe any nonscheduled (non-controlled) prescription drug
- Initiate and manage treatment plans for acute and chronic conditions
- Order medical treatments and therapies
- Receive, order, and dispense complimentary starter dose drugs that are not controlled substances
What Requires Physician Delegation
Only controlled substance prescribing in Schedules 2 through 5 requires physician delegation through a written authorization. No other aspect of the NP’s clinical practice requires physician oversight as a matter of state law, outside of specific institutional or payer requirements.
Controlled Substance Delegation in Michigan
When a physician delegates controlled substance prescribing authority to an NP through a written authorization, specific statutory conditions apply.
Schedule 2 Through 5 Authorization
As of April 9, 2017, Michigan physicians may delegate authority to NPs to prescribe controlled substances in Schedules 2 through 5. Prior to 2017, Schedule 2 delegation was limited to inpatient facility settings only. The current law removed that restriction for outpatient and independent clinic settings.
Schedule II Supply Limit
Under MCL § 333.17210(6), a delegating physician may authorize multiple prescriptions totaling up to a 90-day supply of a Schedule II controlled substance. The physician may allow the NP to issue multiple prescriptions on a single visit to total this supply, but the total authorized supply is capped at 90 days per authorization cycle.
Abortion Prohibition
Under MCL § 333.17210(6)(b), a physician may not delegate to an NP or CNM the prescribing of a drug or combination of drugs intended to cause a miscarriage or fetal death in a patient known to be pregnant. This prohibition applies regardless of the controlled substance involved.
Starter Dose Controlled Substances
If an NP dispenses complimentary starter dose drugs that are controlled substances, that dispensing requires physician delegation, and both the NP’s and physician’s names and DEA registration numbers must be recorded in connection with that dispensing.
The Prescription Documentation Requirement
Michigan has a specific and important documentation requirement for every controlled substance prescription written by an NP under a written authorization. Under MCL § 333.17211a(2) and MCL § 333.17708(2)(i), when an NP prescribes a controlled substance as a delegated act:
- Both the NP’s name and the physician’s name must be used, recorded, or otherwise indicated in connection with that prescription
- Both the NP’s DEA registration number and the physician’s DEA registration number must be used, recorded, or otherwise indicated in connection with that prescription
This dual-name and dual-DEA requirement applies to every controlled substance prescription written under the delegation. One acceptable method is having the physician’s name pre-printed on the prescription form. Another is the NP writing the physician’s name directly on the prescription. Either approach satisfies the documentation obligation.
Medicaid, Medicare, and Third-Party Reimbursement
Michigan’s framework has a specific and important intersection with federal reimbursement programs that distinguishes it from the pure statutory picture.
Medicaid Reimbursement Requirement
Under Michigan Medicaid policy, a collaborative agreement with a physician is required for an APRN to receive direct Medicaid reimbursement. This is a reimbursement condition, not a practice condition. An NP can legally practice and prescribe non-controlled drugs independently under state law, but cannot bill the Michigan Medicaid program without a physician collaboration agreement in place.
This means that for clinic models dependent on Medicaid revenue, a physician collaboration arrangement is practically required even for non-controlled prescribing, despite not being required by the Public Health Code for that activity.
Third-Party Payers
Individual managed care organizations and other third-party payers may impose their own collaboration or supervision requirements beyond what state law mandates. Clinics should verify the requirements of every payer with which they intend to contract before finalizing their physician collaboration structure.
HB 4399: The 2025 Full Practice Authority Legislation
House Bill 4399, introduced in the 2025 to 2026 Michigan legislative session, proposes significant changes to the NP scope of practice framework. The H-1 substitute version, analyzed in November 2025, would allow NPs to prescribe controlled substances in Schedules 2 through 5 without physician delegation, expand the definition of qualifying delegating practitioner to include experienced APRNs, and grant NPs a broader range of enumerated professional responsibilities with statutory clarity.
As of the publication date of this guide, HB 4399 has not been enacted. Democrats control the Michigan Senate and Governor’s Office, but Republicans hold a majority in the House of Representatives in the 2025 to 2026 session. The bill’s passage remains uncertain. Physicians currently entering Michigan written authorization arrangements should monitor HB 4399 closely, as its enactment would significantly reduce the demand for physician delegation for controlled substance prescribing by NPs.
Common Compliance Mistakes Michigan Collaborating Physicians Make
Most Michigan written authorization compliance problems involve documentation gaps on controlled substance prescriptions, missed annual reviews, and misunderstanding the scope of what requires delegation.
- Annual review not documented. The supervising physician must review and update the written authorization annually and note the review date and method. An authorization that has passed one year without a documented review is not current.
- Dual-name requirement not met on controlled substance prescriptions. Every controlled substance prescription written by an NP under the authorization must include both the NP’s name and the supervising physician’s name, along with both DEA numbers. Prescriptions bearing only the NP’s information are noncompliant.
- Authorization copy not maintained at the physician’s primary practice location. The written authorization must be retained at the supervising physician’s primary place of practice. Physicians who sign authorizations without retaining accessible copies at their own practice location cannot produce the document if LARA requests it.
- Delegation includes drugs outside the physician’s scope. The written authorization can only delegate controlled substance prescribing within the physician’s own scope of practice. Physicians should not delegate authority for controlled substances they do not personally prescribe.
- Schedule II supply limit exceeded. The physician may authorize up to a 90-day supply of a Schedule II controlled substance. Authorizations that permit prescribing beyond this limit are noncompliant with MCL § 333.17210(6).
- No Medicaid collaboration agreement for Medicaid-billing clinics. State law permits NPs to prescribe non-controlled drugs independently, but Michigan Medicaid requires a collaboration agreement for direct APRN billing. Clinics that bill Medicaid for NP services without a collaboration agreement face reimbursement denials.

Clinics Also Need to Understand Michigan Collaboration Requirements
While this guide primarily covers the responsibilities and compliance requirements placed on collaborating physicians in Michigan, these regulations directly affect NP-operated clinics, medspas, and healthcare practices that depend on physician collaboration for controlled substance prescribing or Medicaid billing. In many cases, clinic owners researching Michigan collaboration rules are also trying to understand how to find a physician who will issue a written authorization covering the controlled substance schedules their clinical model requires, while also maintaining the annual review and dual-documentation obligations throughout the arrangement.
Need Help Finding a Michigan Collaborating Physician?
For clinics, understanding the legal requirements is only one part of the process. The next challenge is finding a qualified physician who understands Michigan’s hybrid framework, is willing to issue a written authorization covering the controlled substance schedules the clinic needs, and will maintain the dual-name documentation requirement and annual review cycle. Whether you are launching a new NP-operated clinic, expanding to include controlled substance services, or managing the Medicaid billing requirements that make physician collaboration practically necessary even for non-controlled prescribing, having the right physician in place from the start matters.
If your clinic is actively looking for a Michigan collaborating physician, our team can match you with a qualified physician, often within 24 to 48 hours. We work with clinics across Michigan to simplify the physician matching process while supporting written authorization drafting, annual review tracking, and long-term collaboration needs.
Final Thoughts
Michigan collaborating physician requirements reflect a state that has moved further toward NP autonomy than most reduced-practice states, while maintaining a specific and enforceable physician oversight structure for controlled substance prescribing. The written authorization is not a broad collaborative practice document. It is a targeted delegation instrument for a defined category of prescribing, and it carries specific documentation, annual review, and dual-identification requirements that apply to every controlled substance prescription written under it.
For physicians entering the Michigan market, the most important steps are ensuring the written authorization covers the specific schedules and any limitations accurately, establishing the dual-name and dual-DEA documentation process for all controlled substance prescriptions, maintaining the authorization at the physician’s primary practice location, and completing the annual review on schedule.

Frequently Asked Questions
Does a Michigan NP need a physician agreement to prescribe medications?
Only for controlled substances. Michigan NPs and CNMs may independently prescribe nonscheduled (non-controlled) prescription drugs without any physician delegation, authorization, or agreement under MCL § 333.17211a. For controlled substances in Schedules 2 through 5, physician delegation through a written authorization is required before any controlled substance prescription may be written.
What is a written authorization in Michigan?
A written authorization is the formal delegation document through which a supervising physician authorizes an NP or CNM to prescribe controlled substances. It must include both parties’ names, license numbers, and signatures; any limitations on the delegation; and the effective date. The physician must review and update it annually. It is maintained at the physician’s primary practice location, with a copy provided to the NP.
Does both the physician’s and NP’s name need to appear on Michigan controlled substance prescriptions?
Yes. Under MCL § 333.17211a(2), when an NP prescribes a controlled substance as a delegated act, both the NP’s name and the supervising physician’s name must be indicated on the prescription, along with both parties’ DEA registration numbers. The physician’s name may be pre-printed on the form or written by the NP on each prescription.
Does a Michigan physician need to be near the NP’s clinic?
No. Michigan does not impose a geographic proximity requirement on supervising physicians. The physician must be continuously available by telecommunications for consultation but does not need to be physically co-located with the NP.
How many NPs can one Michigan physician supervise?
Michigan does not impose a statutory ratio cap on the number of NPs a physician may supervise under written authorizations. The physician must be able to fulfill the supervision standard, including continuous availability and periodic review, for every active authorization.
What does HB 4399 propose for Michigan NPs?
HB 4399, introduced in the 2025 to 2026 legislative session, proposes to allow NPs to prescribe controlled substances in Schedules 2 through 5 without physician delegation. The H-1 substitute also proposes allowing delegation from experienced APRNs in addition to physicians. As of the publication date of this guide, HB 4399 has not been enacted.
