Since October 1, 2024, only clinics with written approval could get Optum billing reimbursement for clinical trainees. Minnesota is changing that rule for health plans. The duty starts as each plan renews in 2027.

Here's what that means for who you can schedule, and what to line up before you do.

The Optum Supervisory Protocol Stopped New Approvals in 2024

Commercial Optum plans used to require an Optum supervisory protocol before a trainee could see a member. Clinics knew it as a contract addendum, or as a letter that said supervisory billing was allowed.

Optum rewrote the commercial rule effective October 1, 2024. In California, Colorado, Iowa, and Massachusetts, network and out-of-network providers can bill outpatient services delivered under supervision, within state rules. Everywhere else, Optum supervisory billing covers only contracted groups and providers who already had approval on file.^[1]

That approval had to be one of three things, dated on or before September 30, 2024:

Supervisory services written into a fully executed participation agreement
Written confirmation from Optum Behavioral Health, apart from the participation agreement
Other proof that Optum had approved supervisory services

A clinic that opened in 2025, or a small group that never held a group contract, could not get a new approval. NASW-MN has said those permits are closed to new applicants. It also said no other major carrier in Minnesota requires this kind of addendum.^[2]

Go back to the Duluth clinic. Two of the four clinicians cannot see a large share of the commercial caseload. The supervision program that was meant to grow the next licensed clinicians becomes a payer block. Clients feel that as a shorter list of people who can take their card.

Optum left out agencies a state already licenses to use qualified non-licensed staff. That list includes community mental health centers, FQHCs, and similar programs.^[1] The pressure landed on outpatient groups.

Minnesota Now Requires the Licensed Rate

Laws of Minnesota 2026, chapter 124, adds paragraph (l) to Minnesota Statutes, section 62Q.47.

A health plan must pay for alcoholism, mental health, and chemical dependency services that a clinical trainee provides. The rate has to be at least 100 percent of the rate an independently licensed mental health professional would be paid for the same services.^[3]

That's clinical supervisee reimbursement at the licensed rate. Say the licensed contract rate for a 90837 is $140. Once that plan is subject to the law, a covered trainee session has to pay at least $140 too.

The duty covers a service when two things are true. The service sits inside the trainee's scope under section 245I.04, subdivision 7. And the same service would be covered if an independently licensed clinician at that clinic performed it.^[3]

NASW-MN put Minnesota with California, Colorado, Iowa, and Massachusetts. Those states already require this kind of payment.^[2]

For a Minnesota health plan, Optum billing reimbursement for clinical trainees becomes a payment duty. Other fully insured commercial plans in Minnesota already pay these sessions. Medicare stays on its own rules.

Not Every Trainee, and Not Every Optum Card

Section 245I.04, subdivision 6, is the definition a clinic has to use. It names three paths.^[4]

The person is in an accredited graduate program and in a practicum or internship.
The person finished that program and is in the supervised practice the licensing board requires.
The person finished the program and the practicum, and is waiting on the exam or the board's decision.

Under subdivision 7, a trainee working under a mental health professional may provide psychotherapy and client education. The same trainee may provide rehabilitative mental health services, diagnostic assessments, functional assessments, level of care assessments, and treatment plans. A trainee cannot provide treatment supervision to other staff. A psychological trainee under a psychologist may perform psychological testing.^[4]

Optum's current commercial guide is stricter about education. A non-licensed clinician needs at least a master's degree, has to stay inside state scope, and needs regular one-to-one supervision that you document.^[1] After a health plan renews, the statute controls who must be paid. Until Optum says how it will treat a practicum student and a post-degree supervisee, keep those charts apart.

Health plan is a defined legal term. The logo on the card is a separate question. Section 62A.011 covers products such as an insurance policy, a nonprofit health service plan, and an HMO contract. That definition leaves out Medicare supplement policies and Medicare Advantage.^[5] Optum's own guide says federal rules currently do not permit outpatient services under supervision on Medicare Advantage, unless those rules change.^[1] Medicare mental health billing stays on that federal track.

Self-funded employer plans are the other split. Many UMR arrangements are self-funded. Those plans usually sit outside a state benefit mandate, even when Optum processes the claim. A Medica, UnitedHealthcare, or Surest card may be a fully insured health plan. The same family of logos can sit on a plan chapter 124 never reaches. Optum could still choose to pay the self-funded plans the same way. Until it says so, confirm the funding before you promise a trainee opening.

2027 Will Not Switch On All at Once

Paragraph (l) takes effect January 1, 2027, for health plans offered, issued, sold, or renewed on or after that date.^[3]

Renewed is the word that changes your schedule. A plan that renewed on July 1, 2026, can keep its current terms until the next renewal. A plan that renews on January 1, 2027, picks up the duty that day. In a St. Paul group, one Optum member in March may be billable under a trainee. The member in the next hour may still be on last year's contract.

That split is what Optum billing reimbursement for clinical trainees will look like through 2027, unless Optum applies one rule to every Minnesota commercial plan at the same time.

Clinics that already hold the September 30, 2024 approval can keep billing under it. A clinic without that approval needs two things before a new trainee session is billable. The member's health plan needs an offer, issue, sale, or renewal dated on or after January 1, 2027. You also need Optum's billing instructions for that plan.

Denial tracking is how you separate a claim that arrived too early from a claim that was built wrong.

Get the Chart Ready Before Optum Posts the Steps

We hope Optum publishes those steps before the end of November. The central-region place to watch is Optum's Top of Mind newsletter. Subscribe now, so the note reaches the person who builds the trainee schedule.

While you wait, write down four lists:

Which clinicians meet section 245I.04, subdivision 6, and which supervisor signs their work
Which participation agreements already include supervisory services, and the date Optum approved them
Which commercial members sit on fully insured health plans, and which sit on self-funded or Medicare coverage
Which services a licensed clinician at that same clinic can already bill

The statute sets the payment duty. Optum's guide still sets the claim. On a supervised commercial claim, Optum wants modifier U5 on each supervised line, the DQ qualifier with the supervisor's name and credentials, and the supervisor's NPI.^[1] Every supervised line on that claim has to name the same supervisor.

The name in those fields has to be a clinician Optum has contracted and credentialed. If that file is fuzzy, sort contracting and credentialing before the first renewed plan hits your schedule.

When payments arrive, compare them with the licensed rate. A trainee claim that pays at a discount belongs on your underpayment recovery list.

Clinical trainee billing is easier when one person owns the differences. Your BreezyBilling coordinator checks eligibility before the session, sends the claim with the supervisor fields the payer expects, and sits down with you each month to review what paid. Minnesota is our home market. We'll track this shift with you.

Conclusion: Prepare the Caseload Before the First Renewal

Optum billing reimbursement for clinical trainees is now a Minnesota health-plan rule. After a health plan renews in 2027, covered services inside a trainee's scope have to pay at the licensed clinician's rate.

The useful work between now and that renewal is local. Name your trainees. Sort fully insured cards from self-funded and Medicare cards. Keep using an approval you already have. Read Optum's guidance before you open a new trainee's schedule to a commercial Optum member.
