When treatment is waiting on insurance approval

Illinois insurance laws set treatment-approval deadlines and protect access to certain medicines and continuing care.

What it is

Illinois insurance laws set treatment-approval deadlines and protect access to certain medicines and continuing care.

A treatment request can be time-sensitive even before there is a denial. Illinois sets decision clocks for plans covered by its prior-approval law. Separate laws address trying another drug first and care when a doctor leaves the network.

Eligibility rules
  • The Prior Authorization Reform Act includes covered Illinois policies and specified policies issued to HFS for Medicaid or CHIP. It excludes private self-insured ERISA plans and the listed state, local-government and school-district plans from its own scope. Other statutes can still protect a public-plan member.
  • The step-therapy prohibition took effect January 1, 2026 for plans within 215 ILCS 134/87. Generic or interchangeable-biologic requirements and specified Medicaid exceptions remain. The clinic and plan must check the medicine and policy.
  • If a parent works for the state, a city or a school district, the plan follows some of these deadlines but not all of them; the hospital's insurance nurse can check which.
What you get
  • A routine treatment-approval decision within five calendar days once the plan has necessary information.
  • An urgent decision within 48 hours.
  • Protection against required step therapy under the applicable law, with exceptions.
  • Up to 90 days of continuing care when the network-change rules are met.
What the help includes
  • The 90-day continuity protection is in 215 ILCS 124/20. An appointment-protection amendment takes effect January 1, 2027.
  • The clock starts when the plan has everything it asked for, and a refusal must say what was missing. If a doctor leaves the network mid-treatment, or you move to a new plan, treatment with that doctor can continue for up to 90 days.
  • Honoring an existing approval during the first 90 days of a new plan is a separate protection under 215 ILCS 200/70. Network continuity has its own notice, provider-agreement, safety and benefit conditions.
If you decide to apply
  1. Ask the clinic to confirm which law applies to your plan and document when the complete request arrives.
  2. Have request dates, receipt confirmations and delay or denial letters ready.
  3. Ask the clinic to explain urgency where delay would matter. The Department of Insurance can discuss covered-plan complaints.

What happens next
  • The plan responds with approval or a denial explaining the appeal route. A denial can move through internal appeal and, where eligible, external review.
Good to know

The clocks start when the plan has the necessary information. Public-employee and self-funded plans require a separate rules check.

Other details
  • State-employee coverage incorporates specified protections. TRIP is for retired teachers, while local public plans require their own document review.
  • Once the plan approves a treatment, that approval lasts at least six months or the whole course of treatment, and the plan cannot ask you to get the same thing approved twice.
  • If the plan misses its deadline, the request counts as approved. Ask the clinic to get that in writing before treating a bill as covered.
Official sources
Ask your social worker

“If approval is delayed, which deadline applies to our plan and can the clinic show why it is urgent? Would a complaint or appeal help, and could you guide us through it?”

Why I’m asking: I want treatment decisions made on the right timetable and a clear response if a plan delays care.

Additional program information and published rules

Who does what

The three parts, side by side. The agency decides; nobody on this page does.

You

Ask the clinic to send complete requests that name the deadline; write to the plan when a deadline is missed.

Your social worker

The social worker or nurse navigator tracks the request dates.

The care team

Sends the complete request and marks urgent cases as urgent.

Who decides
The plan decides each request; the Department of Insurance enforces the deadlines and the step-therapy ban.
Ask the care team
“Can the prior-authorization request cite the Illinois 5-day or 48-hour deadline and be marked urgent where a delay matters, and can we push back on any step-therapy demand under the 2026 ban?”

How to apply

First step: Ask the clinic to name the 5-day or 48-hour deadline in each request, and to mark urgent requests urgent.

  1. Ask the clinic to name the 5-day or 48-hour clock in every prior-authorization request.
  2. If the plan proposes a cheaper drug first, cite the step-therapy ban in writing.

Official application / program page ↗

Where it starts: Ask the clinic to cite the clock in each request; complain to the Department of Insurance if it is missed.

What to gather

  • Request dates and the plan's receipt confirmation
  • Denial or delay letters

How long: 5 calendar days non-urgent, 48 hours urgent, after the necessary information.

What a yes looks like

Approval inside the deadline; a denial that names how to appeal.

What a no looks like, and the next move

File the internal appeal, then Illinois external review (4 months; 45 days or 72 hours).

Watch out

  • The Illinois 5-calendar-day routine and 48-hour urgent clocks depend on receipt of the necessary information. Requests for missing information do not replace separate federal Medicaid receipt-based deadlines.
  • The Prior Authorization Reform Act names self-insured plans and state, local-government and school-district plans as excluded. Ask a public-employee plan what clocks it follows.
  • There is no general gold-card exemption here. Defined recurring-treatment authorizations can last 6 or 12 months, subject to statutory exceptions. The plan confirms which protection applies.
  • State-employee coverage incorporates specified protections. TRIP covers retired teachers, not every active teacher; its administrator appeal route is plan-specific. Local public plans require their own document check.

If they say no, quote this: Prior Authorization Reform Act 215 ILCS 200/25 and /30: nonurgent determinations within 5 calendar days and urgent within 48 hours of receiving necessary information; 215 ILCS 134/87(f): no step therapy requirements (2026).

Dates that change this

2026-01-01: Step therapy is prohibited for covered plans from January 1, 2026.

2027-01-01: A further continuity protection for a confirmed appointment takes effect January 1, 2027 (P.A. 104-0333); not current law. (not yet confirmed against the final rule)

The numbers and the rules

The arcane layer, kept on purpose. Checked September 10, 2026.

What it is worth

Non-urgent prior authorization decided within 5 calendar days, urgent within 48 hours, of the necessary information; no step therapy from January 1, 2026; 90 days of continued care when a provider leaves the network.

  • $5 — Non-urgent prior-authorization decision (calendar days after necessary information)
  • $48 — Urgent prior-authorization decision
  • $90 — Continuity of care after a provider leaves the network

Legal protection: No step-therapy requirements on covered plans from January 1, 2026 · Prior Authorization Reform Act clocks (5 calendar days; 48 hours urgent) · 90 days of continued care with a departing provider, subject to statutory conditions

What it costs the family: None.

The eligibility facts, as published

Prior auth act
The Illinois Act includes specified HFS Medicaid and CHIP policies as well as covered Illinois-regulated insurance. Private self-funded ERISA plans and specified public plans are excluded. Fully insured status alone does not establish Illinois jurisdiction.
Step therapy
prohibited from 2026-01-01 for plans within 215 ILCS 134; public-plan applicability not established
Continuity
Up to 90 days under 215 ILCS 124/20 when the statutory patient, treatment and provider conditions are met; not every network change qualifies.
Gold card
No general gold-card exemption is established. The Act has recurring-treatment authorization protections, including defined 6-month and 12-month periods subject to exceptions.

Expect friction on: Clocks start on receipt of necessary information

The trap: The deadlines start when the plan has the necessary information. Ask the clinic to send a complete request and to name the 5-day or 48-hour deadline in it.
