Onboarding a New Clinician: The First 90 Days

The onboarding clock starts at offer acceptance, not at the first shift.

Three tracks need to move before day one: hiring paperwork, payer enrollment and verification — in that order, because enrollment is the one that sets when billing can start.

Paperwork.

Every U.S. employer must complete Form I-9 for every person it hires, including U.S. citizens.

Your new clinician completes Section 1 at the time of hire, and you complete Section 2 — the document review — within three business days of the hire date.

For a telehealth hire who will never sit in your office: certain employers may examine the documents remotely under a DHS-authorized alternative procedure and must check the Section 2 box showing they did so; the DHS notice defines who qualifies, so check it before you rely on the option.

Payer enrollment.

Medicare billing privileges for a physician or non-physician practitioner start on the later of the filing date of an enrollment application that is subsequently approved or the date the practitioner first furnishes services at the new practice location — so file the enrollment or reassignment before the start date, not after.

The full sequence, and what commercial payers and Medicaid add on top, is in our guide to the credentialing timeline.

Verification.

If your practice is Joint Commission accredited, the standards require your organization itself to complete primary source verification of any license, certification or registration required by law — a copy of the license alone does not meet the requirement.

HHS-OIG recommends checking the OIG exclusion list before hiring and periodically afterward: no statute or regulation requires the check, but OIG ties it to avoiding civil money penalty liability.

Screening and license verification covers the order to run these in, and monthly exclusion screening covers the re-checks after hire.

ABA practices add one activation step: an RBT's certification is not active — for practice, billing, or use of the title — until a Supervisor or Requirements Coordinator lists the RBT as a supervisee in their BACB portal account.

Do it before the first session — the credential your schedule assumes does not exist until the portal says so.

Week one belongs to the systems the clinician will touch every day: your EHR, your note templates, scheduling and the telehealth workflow.

Give the hire a named supervisor and a named billing contact — the two questions every new clinician carries through month one are "does this note meet your standard?" and "who do I ask?"

Documentation training is the highest-leverage hour of the week.

A 2023 HHS-OIG audit of Medicare psychotherapy payments sorted the deficiencies it found into categories you can train against directly: undocumented psychotherapy time, incomplete or missing treatment plans, no psychotherapy provided or missing documentation, incomplete documentation, wrong code or units, incident-to failures, missing provider signatures, and missing telehealth modifiers.

Walk the new clinician through your note template against that list, then have your billing lead or a senior clinician review their first batch of notes before the claims go out.

Fixing a documentation habit in week one is cheap; fixing it after a payer audit is not.

Policies ride along in the same week: crisis procedures and who covers an emergency, cancellation and no-show handling, records requests, and how to escalate a concern about a client.

The point is not the binder — it is that the clinician hears each rule once, from a person, with somewhere to ask questions.

Whether a new hire's sessions with insured clients can be billed is decided by enrollment status, so plan the ramp around it rather than around a fixed session count.

Medicare is the rule to plan against.

Billing privileges start on the later of the application filing date — of an application that is subsequently approved — or the first date of service at the new location, which is why the filing belongs before day one.

If circumstances precluded enrolling in advance, Medicare lets physicians and non-physician practitioners bill retrospectively for up to 30 days before the enrollment effective date — and the 90-day version applies only after a Presidentially declared disaster.

Treat retroactive billing as a safety net, not a plan.

Commercial payers and Medicaid set their own enrollment and retroactive-billing rules, so ask each payer early.

Incident-to billing comes up in every credentialing-lag conversation, and it is narrower than it looks.

Medicare allows behavioral health services furnished by auxiliary personnel incident to a physician's or practitioner's services under general supervision, and only the supervising practitioner may bill for them.

The arrangement also carries conditions this page does not cover — an established patient and plan of care, an employment or contract relationship, and state law — so it is not a blanket workaround for an unenrolled hire.

Incident-to and supervised billing explains when the model fits.

The clinical side of the ramp is yours to design, and your own numbers are the only ones that count.

Start the schedule lighter than the role's target, protect documentation time until note turnaround is stable, sequence early intakes toward straightforward cases, and expand the caseload as attendance, note quality and session availability hold — productivity and caseload targets covers how to set those numbers.

Very little of a first-90-days plan is legally required, and the required pieces bind different employers differently.

Sort every training by who requires it — federal law, state law, a payer or certification program, or only guidance — and the list stays honest.

Federal law: HIPAA, if you are a covered entity.

The Privacy Rule requires a covered entity to train all members of its workforce on its protected health information policies and procedures, as necessary and appropriate for their functions, and to train each new workforce member within a reasonable period after they join.

The rule sets no fixed number of days and no annual refresher requirement — a same-week gate before independent client work or an annual refresher is your policy, or possibly an accreditor's or payer contract's requirement, but not the Privacy Rule's.

Document that the training was provided.

One scope check: per HHS, a provider is a HIPAA covered entity only if it transmits health information electronically in connection with a transaction HHS has set a standard for, such as electronic claims — a strictly private-pay practice that never does may not be covered at all.

Federal law: OSHA bloodborne pathogens, only where there is exposure.

If any role has occupational exposure — a nurse giving injections, or staff collecting urine or blood specimens in a substance use program — the Bloodborne Pathogens Standard requires training them at no cost and during working hours, at initial assignment and at least annually.

A talk-therapy practice whose roles carry no such exposure may have no covered employees; the duty tracks the job's duties, not the industry.

State law: sexual harassment prevention training, in the states that require it.

California requires employers with five or more employees to provide sexual harassment prevention training — at least two hours for supervisors and one hour for nonsupervisory employees, once every two years — and new nonsupervisory hires must be trained within six months of hire, new supervisors within six months of becoming supervisors.

New York requires every employer to provide sexual harassment prevention training to all employees annually.

Illinois requires sexual harassment prevention training at least once a year for all employees.

California, New York and Illinois are examples, not the whole list — check your own state's law and calendar the deadline when you make the offer.

Payer or certification program: CCBHC criteria, if your clinic is one.

SAMHSA's CCBHC certification criteria require a training plan for all employed and contract staff with direct client or family contact, one that includes the state behavioral health authority's training requirements and any accreditation standards'.

CCBHCs must train staff at orientation and annually on risk assessment, suicide and overdose prevention and response, and the roles of family and peer staff; those trainings may be online.

The criteria also require regularly assessing each clinician's skills and competence, keeping written policies on how competency is assessed, and documenting completed training and competency in personnel records.

Federal guidance, not federal law: a safety orientation before duties.

OSHA's guidelines for preventing workplace violence in healthcare and social service settings recommend that new and reassigned workers receive an initial orientation before they start duties, annual training for all workers, and possibly more frequent refreshers in high-risk settings.

The guidelines are advisory — but walking a new clinician through your crisis and de-escalation procedures before their first session is cheap insurance.

State law can go further.

California's SB 553 (Labor Code 6401.9) requires covered California employers to provide workplace violence training when their plan is first established and annually after that, and California employers under Cal/OSHA's health care standard (8 CCR 3342), which covers drug treatment programs, must train employees when newly hired.

One pay rule runs under all of it: under the FLSA's training-time regulations, attendance at a training need not be counted as hours worked only if all four criteria are met — outside regular working hours, truly voluntary, not directly related to the employee's job, and no productive work performed.

The required, job-related sessions you schedule during onboarding fail those criteria, so build the onboarding calendar as paid time.

Decide the supervision cadence before day one and put it on the calendar — ad hoc check-ins are the first thing a busy clinic week eats.

What the cadence has to contain depends on the hire:

• Associate-level therapists. Supervision requirements are state-specific and vary by license, so confirm the hours, format and supervisor qualifications with the state board before you build the schedule. Each state's rules are collected in the licensure series — counselor licensure by state — and who qualifies to supervise is covered in clinical supervisor requirements.
• RBTs. The before-day-one listing step is what keeps the certification active in the BACB's system; the ongoing supervision duties that come with it — who can supervise, how much, and the records — are covered in RBT supervision for ABA employers.
• Every hire. Add your own layer: a short weekly check-in through the ramp that reviews a sample of notes, the no-show picture, and anything the clinician is deferring because they are not sure who owns it.

What you review matters more than how often you meet.

In the first month, check notes against the same deficiency categories from week one, watch the attendance pattern clients form around a new clinician, and ask directly what has been confusing — then treat every recurring confusion as a gap in your own checklist, not a flaw in the hire.

Close the ramp with a structured review at 90 days, and make it two-sided.

Your side.

Audit a sample of the clinician's notes against the week-one documentation standard.

Sit with your billing lead and look at the claim picture: denials, modifiers, signature errors.

Confirm the caseload has reached the level you planned for the role.

Verify the training file is complete: the HIPAA record, sexual harassment prevention training where your state requires it, bloodborne pathogens if the role has exposure, and anything a payer contract or accreditation body adds.

If your clinic is a CCBHC, the personnel-record and competency requirements in the trainings section are audit items, not suggestions.

Their side.

What was confusing in week one, what the checklist missed, how the caseload mix feels against the job they thought they accepted, and whether supervision is working.

Then change the checklist.

An onboarding plan improves only if each hire's friction edits the next hire's first 90 days.

The review is also your first real retention conversation — the same decisions that shape the ramp (caseload mix, documentation load, supervision fit) are the ones that decide whether the clinician is still there at year one, the argument our guide to retention makes from the why-people-leave side.

And when the process is steady enough to grow on, the behavioral health hiring hub collects the rest of the employer guides.
