Illinois has one of the longest-standing and most comprehensive state infertility insurance mandates in the United States. The original mandate dates to 1991, but Public Act 103-0751, commonly called the Castro Law after State Senator Cristina Castro, took effect January 1, 2026, and eliminated the old threshold that previously limited coverage to employers with more than 25 employees. Any fully insured group health plan issued in Illinois that includes pregnancy-related benefits must now cover IVF, IUI, preimplantation genetic testing (PGT), and related infertility treatments up to 4 oocyte retrievals per lifetime, with 2 additional retrievals after a live birth. For Illinois residents on a qualifying plan, the insurance benefit is significant, potentially saving $15,000 to $25,000 per cycle. The Illinois Department of Insurance oversees compliance.
The mandate does not cover everyone. Self-funded employer plans governed by the federal Employee Retirement Income Security Act (ERISA) are exempt from Illinois state insurance law, and many large employers self-fund their health benefits. Individual market ACA-compliant plans are not required by Illinois law to cover IVF, though some voluntarily do. Religious organization plans and out-of-state policies are also exempt. Illinois Medicaid does not cover IVF. Medicare does not cover IVF under Part A, Part B, or Part D for any patient nationwide. Residents who need to pay out of pocket should compare quotes from multiple Illinois clinics and always request a written Good Faith Estimate before starting treatment. The Chicago Coalition for Family Building and RESOLVE: The National Infertility Association both offer grant programs of up to $10,000 for Illinois residents who qualify.
This guide covers what IVF costs in Illinois in 2026 without insurance, how the Castro Law mandate works and who it applies to, the difference between base cycle fees and all-in costs, how to compare independent fertility clinic rates versus hospital-affiliated center rates, and how to request a Good Faith Estimate from an Illinois fertility clinic. Illinois residents navigating the ACA marketplace should also review the ACA income limits and federal poverty level guidelines to determine whether marketplace subsidies apply to their situation. Patients who receive an unexpected bill after treatment should use the medical bill analyzer to review charges line by line.
IVF in Illinois Cost by Site of Service in 2026
The biggest cost driver of IVF in Illinois is the site of service: where the procedure is performed. 2026 CMS price transparency data confirms a 2-3x billing differential between independent centers and hospital outpatient departments.
IVF in Illinois prices without insurance vs. 2026 Medicare rates| Site of Service | Range Without Insurance | 2026 Medicare Rate |
|---|
| Independent fertility clinic (self-pay, Illinois) | $12,000 to $17,500 | Not covered |
| Academic or hospital-affiliated fertility center (Illinois) | $15,000 to $25,000 | Not covered |
| Mini IVF (minimal stimulation protocol) | $5,000 to $9,000 | Not covered |
| Frozen embryo transfer (FET, after prior retrieval) | $4,000 to $7,000 | Not covered |
2026 Illinois self-pay ranges from Fertility Centers of Illinois, Advanced Fertility Center of Chicago, InVia Fertility, and Chicago IVF published fee schedules. Medications, PGT, ICSI, and embryo storage are billed separately. Medicare and Illinois Medicaid do not cover IVF.

Why the Same Procedure Is So Much More at a Hospital
Illinois IVF cost in 2026 varies significantly by site of service. Independent fertility clinics in the Chicago metropolitan area, including Fertility Centers of Illinois, Advanced Fertility Center of Chicago, InVia Fertility, and Chicago IVF, compete on self-pay pricing because Illinois residents covered by the state mandate still have cost-sharing, and many patients cycle while uninsured or on exempt plans. Independent clinic base fees generally range from $12,000 to $17,500 and cover ovarian stimulation monitoring, egg retrieval, fertilization, embryo culture, and one fresh transfer. Hospital-affiliated fertility programs, including those at Northwestern Medicine and Rush University Medical Center in Chicago, typically run $15,000 to $25,000 for the base cycle because they operate within hospital cost structures that include overhead and facility fees.
Mini IVF uses lower doses of stimulation medications, which lowers medication costs but typically produces fewer eggs per cycle. Frozen embryo transfer (FET) cycles run $4,000 to $7,000 because the costly egg retrieval and fertilization steps occurred in a prior cycle. Most Illinois fertility clinics offer multi-cycle bundled packages at a discount: a typical two-cycle package runs $20,000 to $30,000, which reduces the per-cycle cost if a first fresh transfer does not result in pregnancy. Ask any clinic for the bundle pricing in writing before signing a treatment agreement.
The listed ranges are base procedure costs only. Fertility medications are billed separately and add $3,000 to $7,000 per cycle. Optional add-ons, including preimplantation genetic testing (PGT-A or PGT-M), ICSI (intracytoplasmic sperm injection), embryo cryopreservation, and annual embryo storage, are also typically extra. The chargemaster list price at a hospital-affiliated fertility center can be 50 to 100 percent above the self-pay negotiated rate, so always ask for the self-pay cash rate before accepting a quote at hospital list price.
IVF Cost in Illinois by Component (2026)
A complete IVF cycle in Illinois involves multiple separately billed components. The base cycle fee covers retrieval, fertilization, and one transfer. Everything else, medications, genetic testing, ICSI, cryopreservation, and storage, is typically an add-on. The table below shows typical self-pay ranges for each component in Illinois in 2026.
Typical cost by variant| Component | Typical Illinois Range (2026) | Notes |
|---|
| Base IVF cycle (fresh) | $12,000 to $17,500 | Includes retrieval, fertilization, 1 transfer |
| Fertility medications | $3,000 to $7,000 | Billed separately; varies by stimulation protocol |
| Frozen embryo transfer (FET) | $4,000 to $7,000 | Separate from base cycle |
| Preimplantation genetic testing (PGT-A) | $3,500 to $6,000 | Optional; tests embryos before transfer |
| ICSI (intracytoplasmic sperm injection) | $1,000 to $2,000 | Often recommended for male factor infertility |
| Embryo cryopreservation and first year storage | $700 to $1,500 | Annual storage thereafter $500 to $1,000/yr |
| Mini IVF (minimal stimulation) | $5,000 to $9,000 | Lower egg yield; fewer medications required |
Ranges reflect Illinois self-pay pricing in 2026. Individual clinic quotes may vary by $2,000 to $5,000 for the same components. Always request a written itemized Good Faith Estimate before starting treatment. The Castro Law mandate covers qualifying components on fully insured Illinois group health plans.

What Medicare Pays for IVF in Illinois
Medicare does not cover IVF under any part of the program, including Part A, Part B, or Part D. Original Medicare excludes assisted reproductive technology at the federal level, and this exclusion applies in Illinois the same as in every other state. Medicare Advantage plans are not required to add IVF coverage, though a small number of plans include fertility-related supplemental benefits as optional extras. If you are on Medicare and considering IVF, check your specific plan's Evidence of Coverage document for any supplemental benefit language. Medicare Part B does cover certain diagnostic infertility workups, such as diagnostic ultrasounds and bloodwork, as medically necessary services, but the IVF cycle itself is not a covered benefit under the 2026 Medicare Physician Fee Schedule.
Illinois Medicaid does not cover IVF. The Illinois Medicaid program, administered by the Illinois Department of Healthcare and Family Services (HFS), covers medically necessary services but excludes IVF under federal Medicaid rules. Illinois Medicaid does cover certain fertility preservation services when medically necessary, such as oocyte cryopreservation for cancer patients prior to gonadotoxic therapy. Diagnostic infertility testing, including bloodwork and pelvic ultrasounds, may be separately billable under Illinois Medicaid depending on clinical circumstances. The Illinois Children's Health Insurance Program (AllKids) does not cover IVF. For Illinois residents exploring Medicaid eligibility, review the income limits at medicaid.gov or through the Illinois HFS portal at hfs.illinois.gov.
Commercial insurance coverage under the Illinois mandate (Public Act 103-0751) applies only to fully insured group health plans that include pregnancy-related benefits. An ACA-compliant plan purchased through the Illinois marketplace (GetCoveredIllinois) is not automatically subject to the mandate if it is an individual market plan rather than a group plan. Patients on self-funded ERISA employer plans should check their Summary Plan Description (SPD) or contact their HR department to determine whether IVF is voluntarily included. Even when the Illinois mandate applies, patients typically still pay cost-sharing, such as deductibles and coinsurance, for the services covered. Medigap supplemental plans that pair with Original Medicare do not add IVF coverage because Original Medicare excludes it.
Under the No Surprises Act, effective January 1, 2022, any patient paying cash or who is uninsured has the right to a written Good Faith Estimate from the Illinois fertility clinic before treatment begins. For an IVF cycle scheduled at least 10 business days out, the clinic must provide the Good Faith Estimate at least 3 business days before service. For appointments scheduled 3 to 9 business days out, the Good Faith Estimate arrives at least 1 business day before service. The federal portal at cms.gov/nosurprisesact has full consumer guidance on the Good Faith Estimate process and how to file a dispute if your final bill exceeds the estimate.
To request a Good Faith Estimate for IVF in Illinois in 2026, follow these steps: (1) Call the Illinois fertility clinic and identify yourself as self-pay or uninsured, or as someone whose insurance does not cover IVF. (2) Ask for a written Good Faith Estimate that includes the HCPCS billing codes (S4015 for a complete cycle, S4016 for a frozen cycle), the base cycle fee, the facility component, the anesthesia provider, laboratory fees, and any optional add-ons such as PGT or ICSI that you have agreed to. (3) Provide your ZIP code and confirm any planned add-ons before the estimate is prepared. (4) Confirm the timing: the estimate must arrive at least 3 business days before service if the cycle starts 10 or more business days from today, or at least 1 business day before if it starts 3 to 9 business days from today. (5) Keep the written Good Faith Estimate on file. If your final Illinois fertility clinic bill exceeds the estimate by $400 or more, you have 120 days from the bill date to file a patient-provider dispute resolution claim at cms.gov/nosurprisesact.
A Good Faith Estimate for an IVF cycle in Illinois is not a guaranteed final bill. Common reasons the actual charges exceed the Good Faith Estimate include: additional monitoring visits beyond the estimated number, longer-than-expected egg retrieval procedure requiring extended anesthesia, unexpected ICSI performed on additional eggs not in the original plan, embryo cryopreservation costs when more embryos than expected developed and required freezing, pathology or genetic testing added after the estimate, and medication refills when the stimulation protocol required additional doses. If your final Illinois IVF bill exceeds the Good Faith Estimate by $400 or more, contact the clinic first to dispute the discrepancy, then file through the federal patient-provider dispute resolution portal within 120 days.
What Factors Affect Cost
- Illinois mandate coverage status: patients on a fully insured Illinois group health plan with pregnancy benefits may have significant IVF coverage under Public Act 103-0751, up to 4 oocyte retrievals covered by the insurer after applicable cost-sharing.
- Clinic type: independent Illinois fertility clinics (Fertility Centers of Illinois, Advanced Fertility Center of Chicago, InVia Fertility, Chicago IVF) typically charge $12,000 to $17,500 for a base cycle. Hospital-affiliated programs at Northwestern Medicine, Rush University, and UChicago Medicine typically run $15,000 to $25,000 because of hospital chargemaster cost structures.
- Medication protocol: fertility medication costs vary from $3,000 to $7,000 per cycle depending on the stimulation protocol. Patients using a mini IVF protocol may pay $1,000 to $2,500 in medications. Specialty pharmacy programs and manufacturer coupons can reduce medication costs by 20 to 40 percent for self-pay patients.
- Number of cycles: success rates per cycle vary by age, averaging 50 to 60 percent per retrieval under age 35 and declining to 15 to 20 percent over age 40 (CDC 2022 ART data). Many Illinois patients undergo 2 to 3 cycles before achieving pregnancy, multiplying total out-of-pocket costs. Multi-cycle bundled packages from Illinois clinics typically offer a 10 to 20 percent discount per cycle.
- Add-ons: PGT-A genetic testing adds $3,500 to $6,000; ICSI adds $1,000 to $2,000; donor eggs add $20,000 to $40,000 beyond the base cycle. Each add-on is optional but may be clinically recommended based on individual factors. Under the Illinois mandate, PGT is also covered by qualifying fully insured group plans.
- Independent fertility clinic cash-pay bundles: most Illinois independent fertility clinics publish self-pay package rates that are 20 to 40 percent below their insurance-billed chargemaster rates. Asking explicitly for the self-pay cash price before the first appointment is the single most effective cost-reduction step for uninsured or self-funded plan patients.
- Fertility grants and financial assistance: the Chicago Coalition for Family Building offers grants up to $10,000 for Illinois residents seeking IVF. RESOLVE: The National Infertility Association maintains a national grant database. InVia Fertility offers a Shared IVF Success Program (SISP) allowing prepayment for up to three cycles with a partial refund if treatment is unsuccessful. These programs can substantially reduce out-of-pocket costs for self-pay patients.
- Sliding-scale federally qualified health centers (FQHCs): FQHCs in Illinois may provide sliding-scale fees for diagnostic infertility workups (bloodwork, ultrasound) for patients below 200 percent of the 2026 federal poverty level. FQHCs do not perform IVF cycles themselves. Patients may use FQHC services for the initial diagnostic phase and then transition to a specialty fertility clinic for the IVF procedure. Link out to the federal poverty level chart to determine income eligibility.
Common IVF in Illinois Billing Errors
IVF billing in Illinois is complex and itemized. The mandate coverage adds another layer: errors can occur both in what is charged to self-pay patients and in what is incorrectly billed to insurance. Check for these common errors before paying an Illinois IVF bill:
- PGT biopsy fee charged for embryos that never developed enough to be biopsied, or ICSI billed on all retrieved eggs when it was only performed on a portion.
- Anesthesia billed by a separate out-of-network provider when the facility is in-network. The No Surprises Act protections may apply; do not pay before verifying the anesthesiologist's network status.
- Medications billed at retail pharmacy prices when a specialty pharmacy or clinic-dispensed price was available at a lower rate. Always ask whether the clinic has a preferred specialty pharmacy arrangement.
- Frozen embryo transfer billed at a fresh cycle rate when a lower FET rate was agreed upon in writing.
- Illinois mandate coverage incorrectly applied: the clinic submits the claim as non-covered when the patient's fully insured Illinois group plan should cover it under Public Act 103-0751. Request an itemized explanation of benefits (EOB) from your insurer and compare the codes to what the clinic submitted.
- Lab and monitoring fees charged separately when the clinic's package represented them as included in the base cycle fee.
Frequently Asked Questions
How much does IVF cost without insurance in Illinois in 2026?
Without insurance, a standard IVF cycle in Illinois costs $12,000 to $17,500 for the base procedure in 2026 at an independent fertility clinic. Adding fertility medications ($3,000 to $7,000) brings the realistic all-in total to $15,000 to $25,000 per fresh cycle. Hospital-affiliated fertility programs in Chicago can run $15,000 to $25,000 for the base cycle alone. Optional add-ons like PGT genetic testing ($3,500 to $6,000) or ICSI ($1,000 to $2,000) add further. The national median for an IVF cycle in Illinois is approximately $15,450 without insurance according to CareGostIndex 2026 data.
Does Illinois require insurance to cover IVF in 2026?
Yes, for fully insured group health plans. Illinois Public Act 103-0751 (the Castro Law), effective January 1, 2026, requires every fully insured group health plan issued in Illinois that includes pregnancy-related benefits to cover IVF, IUI, PGT, and related infertility treatments. Coverage extends to up to 4 oocyte retrievals, with 2 additional retrievals after a live birth. The mandate covers LGBTQ+ couples and single individuals. However, self-funded ERISA employer plans, individual market ACA plans, plans from out-of-state insurers, and religious organization plans are exempt. Medicare and Illinois Medicaid are also excluded.
What does Medicare pay for IVF in Illinois?
Medicare does not cover IVF under any part of the program. Original Medicare excludes assisted reproductive technology at the federal level, applying this exclusion equally in Illinois and all other states. Medicare Advantage plans are not required to cover IVF, though a small number may offer fertility-related supplemental benefits voluntarily. Medicare Part B does cover diagnostic infertility workup services such as ultrasounds and bloodwork when medically necessary, but the IVF cycle itself is excluded from the 2026 Medicare Physician Fee Schedule. The 2026 Part B deductible of $283 and 20 percent coinsurance apply to any diagnostic services that are covered.
How do I request a Good Faith Estimate for IVF in Illinois?
Under the No Surprises Act, Illinois fertility clinics must provide a written Good Faith Estimate to self-pay and uninsured patients before treatment. Call the clinic and identify yourself as self-pay. Ask for a written Good Faith Estimate itemizing the base cycle fee (HCPCS S4015 or S4016), anesthesia provider, laboratory fees, and any agreed add-ons. Confirm the timing: if your cycle starts 10 or more business days from today, the estimate must arrive at least 3 business days before service; if scheduled 3 to 9 business days out, at least 1 business day before. Keep the estimate. If your final bill exceeds it by $400 or more, file a dispute at cms.gov/nosurprisesact within 120 days of the bill date.
What is the No Surprises Act and does it apply to IVF in Illinois?
The No Surprises Act took effect January 1, 2022, and applies to all providers, including Illinois fertility clinics, for self-pay and uninsured patients. The law requires providers to give a written Good Faith Estimate of expected charges before scheduled services. If the final bill exceeds the Good Faith Estimate by $400 or more, the patient has the right to file a patient-provider dispute resolution claim within 120 days through the federal portal at cms.gov/nosurprisesact. The No Surprises Act does not apply to patients with insurance unless the provider is out-of-network, in which case separate balance-billing protections apply. Illinois fertility patients on exempt plans (self-funded ERISA) who pay out of pocket have full No Surprises Act protections.
How do I get a written cash-pay quote for IVF at an Illinois clinic?
Call the clinic's financial counselor before scheduling and ask: 'What is your self-pay cash price for a complete IVF cycle?' Request the quote in writing as a Good Faith Estimate that itemizes every component: base cycle, anesthesia, lab fees, embryo cryopreservation, and any monitoring beyond what is included. Compare quotes from at least three Illinois clinics. Independent clinics like Fertility Centers of Illinois, Advanced Fertility Center of Chicago, InVia Fertility, and Chicago IVF typically publish self-pay rates or provide them on request. Hospital-affiliated center cash rates may be negotiable against the chargemaster list price. Always ask whether the cash price differs from the insurance-billed rate before deciding how to pay.
Can I negotiate an IVF bill after the fact in Illinois?
Yes. If your final IVF bill from an Illinois clinic exceeds your Good Faith Estimate by $400 or more, you have the right to dispute it through the federal patient-provider dispute resolution process at cms.gov/nosurprisesact within 120 days. Even without a Good Faith Estimate dispute, most clinics will negotiate a payment plan or a reduced cash-settlement amount for self-pay patients who proactively request it before the account goes to collections. If a line item on the bill does not match services rendered, dispute it directly with the clinic's billing department and request an itemized bill. The Illinois Department of Insurance (insurance.illinois.gov) handles complaints against fully insured plans that improperly deny IVF coverage under the Castro Law mandate.
What is the difference between IVF cost with the Illinois mandate versus without?
Patients with a qualifying fully insured Illinois group health plan under Public Act 103-0751 can have most IVF costs covered by their insurer, subject to their plan's deductible, copay, and coinsurance. A patient with a $3,000 deductible and 20 percent coinsurance might pay $5,000 to $8,000 per cycle rather than $15,000 to $25,000. Patients on self-funded ERISA plans, individual ACA marketplace plans (GetCoveredIllinois), or with no insurance pay the full out-of-pocket rate. According to CareGostIndex 2026, the average insured out-of-pocket cost for IVF in Illinois is approximately $5,150 versus $15,450 uninsured, a savings of roughly 67 percent for mandate-covered patients.
Is IVF covered by ACA-compliant plans in Illinois?
ACA-compliant individual market plans purchased through GetCoveredIllinois are not automatically required by the Illinois mandate to cover IVF. The Castro Law applies to fully insured group health plans with pregnancy benefits, not to individual market plans. However, some ACA-compliant plans in Illinois voluntarily include fertility coverage, and a marketplace plan's Summary of Benefits will state whether IVF is included. ACA plans do cover required preventive services, but IVF is not a USPSTF preventive service and therefore has no ACA preventive-care mandate. Check your plan's Summary of Benefits before assuming coverage.
What is the difference between IVF and IUI, and does Illinois insurance cover both?
IVF (in vitro fertilization) involves retrieving eggs from the ovaries, fertilizing them with sperm in a laboratory, and transferring embryos to the uterus. IUI (intrauterine insemination) is a simpler and less expensive procedure where prepared sperm is placed directly into the uterus during ovulation. IUI typically costs $500 to $2,000 per cycle in Illinois versus $12,000 to $25,000 for a full IVF cycle. Both IVF and IUI are covered under Illinois Public Act 103-0751 for qualifying fully insured group health plans. IUI is often attempted before IVF as a less invasive first step. The mandate also covers diagnostic infertility testing for both.
