IDD Medicaid rates in Illinois are set in the DHS Division of Developmental Disabilities (DDD) rate table, and most are published per client hour rather than in the 15-minute units other states use. The one Illinois residential rate that ranks nationally is low: Illinois pays $108.00 a day for residential habilitation on code 60D. That ranks 30th of 31 states and is 61.5% below the national median of $280.27.
Illinois is also in the middle of a rate cycle. The state raised DD wages and rates on January 1, 2026, and a public notice dated 09/10/2026 proposes a further 10.0% change for the Adults with Developmental Disabilities waiver. This page explains the current rates, how they compare and what the pending changes mean for providers. Rates are compiled from official state Medicaid publications and link to their source documents.
| Service | Illinois code | Illinois rate | Effective since |
|---|---|---|---|
| In-home and community living supports | 62H | $30.73 / client hour | 2026-01-01 |
| Day habilitation | 38C | $20.94 / client hour | 2026-01-01 |
| Supported employment | 33G | $26.09 / client hour | 2026-01-01 |
| Prevocational services | T2014 | $76.74 / day | 2026-07-01 |
| Behavior support | 56U | $78.07 / hour | 2026-01-01 |
| Residential habilitation | 60D | $108.00 / day | 2026-01-01 |
Behavior support and residential habilitation are ranked against other states. The client-hour rates and the daily prevocational rate are published in units that do not line up with other states, so they are not ranked.
Illinois runs IDD services through the DHS Division of Developmental Disabilities HCBS waivers: Adults with DD, Children's Support and Children's Residential. Rates for all three come from the DDD rate table, which lists each service by an Illinois-specific code such as 62H, 38C, 33G or 60D. ICF/DD and MC/DD facility rates are separate and paid fee-for-service by HFS.
What a client hour means
Most Illinois DDD rates are published per client hour. A client hour is an hour of service delivered to one person, so in a group setting the provider bills one client hour for each person present. That makes the unit comparable in spirit to an hourly rate elsewhere, but service definitions and staffing assumptions differ, which is why these rates are shown here without a national rank.
Codes and suffixes
Illinois codes end in a letter that helps identify the service type. Billing staff moving from another state need to map every service to this code list and should not assume a national HCPCS equivalent carries the same definition. Our methodology explains how units are compared and when a rate is left unranked.
Only Oklahoma, at $88.66, pays less than Illinois for residential habilitation among the 31 ranked states. Iowa ($140.81) is the next lowest. At the top, Minnesota lists $999.00 a day, the District of Columbia $567.62 and New York $564.22. See the national comparison on T2016.
For context, Illinois's residential advisor median wage is $21.22 an hour in May 2025 federal data, above the $20.31 national figure. A daily rate of $108.00 covers only a few hours of staff time at that wage, so residential providers should check how 60D fits with the other DDD rate table codes billed for the same person.
Why the rank needs context
A ranked daily rate compares like with like only when the rate is meant to fund the whole day of support. Where a state pays residential care through several codes billed together, a single code can look low on its own. Illinois providers benchmarking against other states should total every code billed for a resident before drawing conclusions from the 60D rank.
Illinois pays $30.73 per client hour for in-home and community living supports on 62H. The national median for this service is $34.92 an hour, with South Carolina at $85.96 on T2017 and Louisiana at $12.40.
Day habilitation on 38C pays $20.94 per client hour, against a national median of $23.14 an hour. Supported employment on 33G pays $26.09 per client hour, against a national median of $40.84. Prevocational services on T2014 are paid as a daily rate of $76.74, effective 2026-07-01.
Read side by side, the client-hour rates sit somewhat below the national medians for comparable services. With an Illinois direct support median of $22.57 an hour, the in-home rate of $30.73 leaves limited room once payroll taxes and benefits are added, and the supported employment rate of $26.09 leaves less. Day habilitation at $20.94 per client hour depends on group delivery to cover a worker's hour.
Coverage records show a State FY limit on each of the DDD codes we track, including 31C, 31U, 32G, 33G, 34G, 34U, 36G, 36U, 37U, 38C, 38U, 41D, 56U, 60D, 61H and 62H. None carries a prior authorization rule.
Providers should track each person's annual units against the state fiscal year rather than the calendar year. Because Illinois rate increases often take effect on January 1, the middle of the state fiscal year, an agency can see a rate change and a unit-limit reset at different points in the year. Budgets that assume both happen together will be wrong in at least one half of the year.
Behavior support on 56U with the L2 modifier pays $78.07 an hour, exactly the national median, and ranks 12th of 23 states. The leaders are Maryland ($173.04), New Hampshire ($167.32) and Kentucky ($160.96); the lowest are New Jersey ($33.20), Tennessee ($27.00) and Idaho ($24.64).
The L2 modifier identifies a level of behavior support, so the rate reflects one credential tier. Agencies employing clinicians at different levels should check the modifier for each and budget clinician time against the matching rate.
Illinois publishes an ICF/IID rate of $711.12 per person, per day, effective since 2015-07-01. ICF/IID (ICF/DD) and MC/DD facility rates are paid fee-for-service by HFS under the program Illinois Medicaid ICF/IID (ICF/DD) and MC/DD facility rates. The national ICF/IID median is $464.88.
May 2025 federal occupational data puts Illinois wages above the national median for every IDD role:
- Direct support professional: $22.57 vs $22.08 nationally (based on the closest comparable occupation)
- Residential advisor: $21.22 vs $20.31
- Home health / personal care aide: $18.30 vs $17.21
- Licensed practical nurse: $36.06 vs $30.96
Above-median wages paired with a near-bottom residential rate are the core cost pressure for Illinois residential providers.
Illinois has a series of rate actions in progress:
- January 1, 2026 Wage/Rate Increase and HBS Rates Increase 2026, both effective 2026-01-01, set most of the current rates above. The same pair of actions took effect a year earlier, on 2025-01-01.
- HFS public notice 10/14/2025, an IDDD MCDD reimbursement rate increase effective 2026-01-01, followed by an 08/14/2026 public notice for an ID/DD MC/DD rate increase effective 2027-01-01.
- 09/10/2026 public notice, HCBS Waiver for Adults with Developmental Disabilities, with a 10.0% change.
- 09/10/2026 public notice, HCBS Residential Waiver for Children and Young Adults with Developmental Disabilities (corrected).
- Children's Residential Waiver proposed amendment, effective 01/01/2027, with a 3.0% change.
The proposed 10.0% change for the adults waiver is the one adult-services providers should budget for. Illinois has followed a January 1 pattern for wage and rate increases two years running, so January 2027 is the date to model.
Our managed-care classification lists intellectual and developmental disability services as paid directly by the state, outside managed care. Broader home and community-based services and personal care follow a different rule, under which plans must pay at least the published rate. Illinois's IDD plan listings count 71 entries, reflecting the state's large managed-care program. See the Illinois managed care page.
For a DD waiver provider, the practical meaning is that the DDD rate table is the rate, with no plan contract in between. For an agency that also delivers non-DD home and community-based services to plan members, the published rate is a floor in those contracts.
Illinois sits in a region with very different IDD rate levels. Missouri pays $48.56 an hour for day habilitation and $77.80 for supported employment, both among the higher rates nationally. Iowa is just above Illinois at the bottom of the residential ranking, at $140.81 a day, and Indiana pays the lowest day habilitation rate of any ranked state, $6.54 an hour. On ICF/IID care, Wisconsin's $201.04 a day sits far below Illinois's $711.12.
For providers operating near state lines, those differences affect both recruiting and program design. A day program across the river in Missouri earns considerably more per participant hour than an Illinois program billing 38C, while Illinois ICF/DD operators are paid well above their Wisconsin counterparts.
- Budget on the state fiscal year. Align unit tracking with State FY limits and model January rate changes separately.
- Total residential codes before benchmarking. Compare the full set of codes billed per resident, not 60D alone.
- Model January 2027 both ways. Run adult waiver budgets with and without the proposed 10.0% change.
- Watch the MC/DD notice. Facility operators should follow the 08/14/2026 notice through to final rates.
