Start with license readiness

Your license type determines whether you can practice independently, need supervision, or should set up inside a group practice first. Confirm the current rules with the state board before accepting clients.

This table is a setup readiness starting point, not a substitute for current board review.

Credential	Independent practice?	Supervision issue?	Entity/business note	Bomi relevance	Official source
LCSW	Generally the independent clinical social work path; confirm active status and scope with IDFPR.	Keep supervision documentation if recently upgraded or joining a group.	Match legal name, assumed name, EIN, NPI, CAQH, W-9, EHR, and payer records.	Strong fit for credentialing, eligibility, claims, denials, and revenue reporting support.	IDFPR Social Work licensing
LSW	Confirm whether your specific role and supervision status allow independent private practice.	Supervision requirements may affect whether solo setup is appropriate.	Do not form payer-facing records until license readiness is clear.	Bomi can help later if the setup path moves into payer setup under an eligible practice model.	IDFPR Social Work licensing
LCPC	Generally the independent clinical counseling path; confirm current license status with IDFPR.	Confirm any supervision, renewal, or title-use requirements before setup.	Professional naming and payer records should stay consistent across systems.	Bomi can support CAQH, payer follow-up, billing setup, claims, and denials.	IDFPR Professional Licensing in Illinois
LPC	Confirm whether the license supports independent practice or requires supervised clinical work.	Supervision limitations can change whether solo setup, group setup, or employment is the right next step.	Avoid payer applications until license independence is confirmed.	Bomi becomes relevant once the credentialing and billing path is allowed and ready.	IDFPR Professional Licensing in Illinois
LMFT	Confirm active marriage and family therapy license status and scope before starting.	Check whether any associate, temporary, or supervised status applies.	Keep practice address, legal entity, NPI, CAQH, and payer records aligned.	Bomi can help with payer setup and billing operations once the practice is claim-ready.

Clinical psychologist	Confirm active psychologist license status and any professional entity expectations.	Post-degree or supervised statuses should be resolved before independent setup.

Next step: confirm your state board rulesUse the official Illinois licensing source before you decide whether to setup independently, stay supervised, or join a group first.

National steps

These steps are not unique to Illinois, but they still need to match the state, address, entity, tax, payer, and EHR details you use for setup.

Decide Type 1 NPI versus Type 2 NPI and whether the practice will bill under an individual or organization.
Create or update CAQH and keep attestations current.
Align EIN, W-9, business bank account, and payer-facing business identity.
Confirm HIPAA privacy/security, Notice of Privacy Practices, consent forms, Good Faith Estimate workflows, and documentation setup.
Select EHR, clearinghouse, billing workflow, payment processor, ERA/EFT workflow, and denial-management process.
Build a credentialing packet with license, malpractice, NPI, CAQH, W-9, bank documentation, taxonomy, service address, telehealth policies, and supervisor information if applicable.
Track payer applications, effective dates, portals, claim test dates, ERA/EFT status, and recredentialing deadlines.

Next step: clean up NPI and CAQHMake sure your individual NPI, organizational NPI decision, taxonomy, CAQH profile, W-9, and practice address are consistent before payer applications start.

State-specific steps

Business entity options

Illinois therapists should confirm whether their discipline and ownership structure require a specific professional entity setup before filing. Keep legal name, assumed name, EIN, NPI, CAQH, W-9, EHR, and payer records consistent.

Next step: align entity details with billing recordsBefore payer setup, make sure your entity name, EIN, W-9, NPI, CAQH, EHR, and bank details will all tell the same story.

State and tax registration

Use Illinois and federal tax resources to confirm whether the practice needs state tax registration beyond federal EIN and normal income-tax workflows.

Next step: prepare EIN, banking, and payer paperworkUse the setup checklist to track financial setup before credentialing asks for tax and payment details.

Telehealth notes

Telehealth rules depend on license type, client location, payer rules, consent, documentation, and any applicable temporary or compact rules.

Next step: configure EHR and telehealth workflowsSet the client-facing workflow for scheduling, consent, documentation, payments, and billing before the first appointment.

Mandated reporting notes

Mandated reporting requirements should be checked directly against Illinois law and the license board guidance for the therapist's discipline.

Next step: build forms and policy review into setupKeep clinical policies, privacy workflows, intake forms, and billing policies on the same setup checklist.

Insurance credentialing notes

Commercial payer and Medicaid managed care workflows can vary by plan. Track application status, effective dates, Availity or portal setup, EFT, and claim testing.

Next step: Map your payer listChoose target payers, gather packet details, and track every application through effective date and claim readiness.
