Signing for a Nurse Practitioner in Illinois: what the physician takes on

The agreement is mandatory for the clinician, which makes its duties mandatory for you. Illinois calls the instrument a Written Collaborative Agreement.

Full practice authority pathway created by 2017's Public Act 100-0513 (225 ILCS 65/65-43). Until the attestation threshold is met, every NP in active clinical practice must maintain a written collaborative agreement with a physician, with limited exceptions for hospital/ambulatory-surgical settings.

Independent practice requires: ≥4,000 hours of clinical practice under a written collaborative agreement after first attaining national certification; ≥250 hours of continuing education/training; a notarized full-practice-authority attestation filed with IDFPR.

What you take on as the physician

The rules the physician relationship has to follow. Each fact comes from the statute or board rule listed under sources.

Proximity

below full-practice-authority attestation: Available remotely (no on-site requirement)

No codified mile/minute radius or on-site requirement; the written collaborative agreement governs availability for consultation.

Supervision ratio

Not codified — no cap on file

Chart review

Not codified — left to the agreement

Meeting cadence

Not codified — left to the agreement

Prescriptive authority

below full-practice-authority attestation: Separate prescribing terms required · controlled substances permitted

Prescriptive scope, including controlled substances, must be set out in the written collaborative agreement (Ill. Admin. Code tit. 68, § 1300.430).

at/after full-practice-authority attestation: Covered by the practice agreement · controlled substances permitted

Independent prescriptive authority once the attestation is filed (Ill. Admin. Code tit. 68, § 1300.465).

Written agreement

Required

Practice ownership (corporate practice of medicine)

Licensee-only ownership required — NPs are excluded from the physician-only Medical Corporation Act (805 ILCS 15) — even a full-practice-authority NP cannot own that entity. NPs instead use a professional service corporation (805 ILCS 10) or PLLC (805 ILCS 185) held by nursing licensees.

Ownership is unaffected by whether the NP has reached full-practice-authority status — the attestation above governs clinical collaboration, not entity ownership.

About Illinois's rules

The 2017 Nurse Practice Act reform (P.A. 100-0513) lets NP/CNM/CNS attest to full practice authority after 4,000 hours under a written collaborative agreement plus 250 hours of CE — CRNAs are not included in that attestation pathway. The Medical Corporation Act (805 ILCS 15) restricts clinical-entity ownership to physicians; APRNs/PAs may still use a professional service corporation or PLLC of their own licensees.
