The Illinois Medicaid fee schedule isn’t one document. It’s a collection of reimbursement schedules issued by the Illinois Department of Healthcare and Family Services (HFS), each listing payment amounts, procedure codes, and billing policies for a specific slice of care.
For practitioners, the latest schedule is effective July 1, 2026, updated August 11, 2026. HFS also publishes a fee schedule key and a separate modifier file alongside it.

Last verified: September, 2026. Use the schedule that matches your provider type and the actual date of service — not whichever file happens to load first.
What Is the Illinois Medicaid Fee Schedule?
It’s how HFS establishes and publishes reimbursement amounts for covered services. Here’s the part people miss: Illinois doesn’t run one universal schedule for every service. HFS maintains separate resources for:
- Practitioner services
- Dental services
- Durable medical equipment (DME)
- Home health
- Therapy
- Transportation
- Hospital services
- Pharmacy
- Long-term care
- Behavioral health
- FQHC and RHC services
- Specialized programs
The official HFS directory lists these separately, and that distinction matters the moment you search for an actual CPT or HCPCS rate.
Where to Find the Official Illinois Medicaid Fee Schedule
Start at the HFS Medicaid Reimbursement directory, then pick the schedule matching your service or provider type — not whichever ranks first on Google.

| Dentist | Dental Fee Schedule |
| DME supplier | DME Fee Schedule |
| Therapist | Therapy Providers Fee Schedule |

Current 2026 practitioner schedule
The HFS Practitioner page lists:
- Effective July 1, 2026 — updated August 11, 2026
- Practitioner Fee Schedule Key effective July 1, 2026
- Modifier file effective August 1, 2026, updated August 5, 2026
- Earlier January 1 and April 1, 2026 versions
A search result labeled “2026 Illinois Medicaid fee schedule” won’t tell you which version applies. You have to check.
How to Look Up an Illinois Medicaid Reimbursement Rate
Follow this order. Skipping steps is how people end up appealing denied claims.
Step 1: Identify the procedure code — CPT, HCPCS, CDT, NDC, or revenue code. Don’t search the rate alone; the code comes first.
Step 2: Identify the provider and service category. A physician, a dentist, a DME supplier, and a hospital pull from entirely different HFS resources.
Step 3: Check the date of service. This trips people up most. A schedule updated in August doesn’t automatically apply retroactively — look at the effective date, not the posting date.
Step 4: Open the applicable HFS schedule — the Practitioner Fee Schedule for most professional services, something else for everything else.
Step 5: Use the fee schedule key. It explains fields, indicators, and pricing conventions you’d otherwise miss.
Step 6: Check modifiers and billing requirements. Units, place of service, and components can all change what actually gets paid.
Step 7: Verify coverage and authorization. A code appearing on a schedule doesn’t mean every diagnosis qualifies for payment.
Step 8: Confirm the payer. FFS or a HealthChoice Illinois MCO? This one decides everything downstream.
How to Read an Illinois Medicaid Fee Schedule
A fee schedule holds more than a dollar figure. Expect fields for:
- Procedure code
- Service description
- Reimbursement rate
- Maximum quantity
- Effective date
- Program coverage
- Modifier
- Professional component
- Technical component
- Global component
- Hand-priced services
- Prior authorization
- Special billing instructions
Treat the fee schedule key as part of the schedule, not a footnote. On a complicated claim, the key — not the rate table — usually explains the mismatch.
CPT vs HCPCS: Which Code Do You Need?
CPT codes identify professional medical procedures. HCPCS is broader, covering Level II codes for items like DME, supplies, and certain drugs.
Office visits and most professional services run on CPT. DME leans on HCPCS Level II. Dental work uses CDT coding, and pharmacy claims bring in NDCs with their own rules. Get the code family right before hunting for a number.
Illinois Medicaid Fee Schedule by Provider Type
Practitioner
This is the most-searched HFS resource. The current version is effective July 1, 2026, with its key and modifier file published alongside it. Physicians are paid fee-for-service; other practitioner types follow different arrangements. If income eligibility factors into your reimbursement questions, the Medicaid income limits breakdown is worth a look.
Dental
Illinois runs a separate dental schedule. The 2026 version is effective July 1, 2026, updated July 21, 2026, and it comes with its own CDT coding requirements and program-specific rules.
Durable Medical Equipment
DME suppliers shouldn’t borrow from the practitioner schedule. HFS lists a dedicated 2026 DME fee schedule effective January 1, 2026, updated April 1, 2026, plus its own fee schedule key.
Therapy, Home Health and Transportation
Each has its own dedicated resource. Don’t substitute a physician rate just because the underlying service looks medically similar — HFS doesn’t treat it that way.
Hospital, Pharmacy and Long-Term Care
These use their own payment methodologies. It’s exactly why “Illinois Medicaid rate” means nothing on its own — you need the provider type, service, and payment system before the phrase says anything useful.
Illinois Medicaid FFS vs HealthChoice Illinois Managed Care
People assume the FFS fee schedule is what every provider gets paid. It isn’t.
| Feature | Medicaid FFS | Managed Care |
|---|---|---|
| Primary reference | Applicable HFS reimbursement schedule | MCO requirements and contract |
| Payment model | Service-based reimbursement | Managed-care arrangement |
| Provider contract | Not necessarily applicable | Generally important |
| Coding | HFS rules and billing requirements | HFS + applicable MCO requirements |
| Published rate | Does not guarantee payment | Contract terms may determine payment |
HFS itself points providers to their MCO for billing policy and procedure.
Why this matters
Providers in HealthChoice Illinois work through an MCO, and that MCO’s contract terms sit alongside — sometimes ahead of — HFS policy. The HFS FFS rate doesn’t guarantee MCO payment; if you’re investigating a discrepancy, this is usually where the answer lives. Comparing how Medicaid fee schedules vary by state helps if you work across more than one program.
Why Your Actual Medicaid Payment May Differ
A published rate isn’t a promise:
- Date of service
- Provider type
- Eligibility
- Covered-service rules
- CPT/HCPCS code
- Modifier
- Units
- Place of service
- Prior authorization
- Medical necessity
- Claim edits
- NCCI edits
- FFS versus managed care
- Provider contract
- Corrected-claim processing
- Other applicable billing policies
The fee schedule is a reference point. It was never a guarantee.
Modifiers, Fee Schedule Keys and Special Pricing
Modifiers change how a service is read and reimbursed. Professional and technical components can be split, and some codes carry restrictions you won’t see coming.
The current Practitioner page lists a modifier file effective August 1, 2026. Don’t assume modifier 26 or TC behaves the same way it does with another payer — Illinois Medicaid has its own instructions.
Prior Authorization and Medical Necessity
A rate on a schedule doesn’t mean a service can be billed without a green light first. HFS flags prior authorization requirements across DME, home health, dental, therapy, and transportation. Before submitting, confirm coverage, authorization status, patient eligibility, provider enrollment, and payer type.
2026 Illinois Medicaid Reimbursement Updates
Illinois Medicaid reimbursement isn’t frozen for the year — it moves. The practitioner page alone lists separate 2026 versions effective January 1, April 1, and July 1.
HFS also issued a July 2026 behavioral-health notice requiring specific modifiers on procedure code 96127 for dates of service beginning August 1, 2026, across both FFS and MCO claims. Separately, Medicaid billing for Licensed Certified Professional Midwives began May 1, 2026. If work requirements factor into your state’s eligibility conversations, the Medicaid work requirements by state guide tracks where those policies stand. Check HFS regularly — this isn’t set-it-and-forget-it.
Historical Illinois Medicaid Fee Schedules
Old claims, corrected claims, and payment disputes all need historical schedules, and HFS keeps an archive of past practitioner versions and their effective dates. Record the date of service, original claim date, procedure code, provider category, schedule version, modifier, payer, and any relevant provider notice — and don’t swap in today’s schedule just because it’s easier to find.
Illinois Medicaid Provider Enrollment and Billing
Correct reimbursement starts before a claim is ever submitted. Providers need enrollment through IMPACT, Illinois’s Medicaid provider enrollment system, along with an applicable NPI. The Illinois Medicaid Provider Directory lets you search participating providers by NPI, provider type, and category of service.
Beyond that, billing operations touch on the billing provider, rendering provider, service location, 837P electronic claims, MEDI, remittance advice, corrected claims, provider notices, and provider handbooks — all of which matter more than the rate table when the question is policy, not price.
What Illinois Medicaid Members Should Know
If you’re a member rather than a billing professional, you don’t need to calculate anyone’s reimbursement rate.
Questioning a bill? Ask whether the provider participates in your plan, whether the service is covered, whether the claim went to the right payer, whether an MCO is involved, and whether you’re being charged something you shouldn’t owe. A provider’s reimbursement has nothing to do with your personal financial responsibility.

Illinois Statewide and Regional Considerations
The same HFS framework applies everywhere — Chicago, Cook County, Springfield, Peoria, Rockford, Aurora, Naperville, Joliet, Champaign, Bloomington, Decatur, Rock Island, East St. Louis, Carbondale.

Conclusion
Rate lookups go wrong when people skip straight to the number. Code, date of service, provider category, HFS schedule, fee schedule key, modifier, coverage and authorization, FFS or MCO — work through that order and the rate makes sense by the time you get there. HFS revises these plans throughout the year, so the source you trusted 6-months ago deserves a second look before you rely on it again.
