1. Program Definition and Services

Home Modification Services, regionally managed as Environmental Accessibility Adaptations (EAA) or Architectural Modifications (AM), provide physical and structural alterations to an individual's private home. The program is designed for children and adults with physical, developmental, or age-related disabilities to eliminate environmental barriers, reduce safety hazards, and maximize independence in daily living, thereby preventing institutional placement. Services include:

• In-Home Personal Care (Structural Adaptation): Executing permanent structural reconfigurations within the participant's living space (constructing wheelchair ramps, widening doorways, installing roll-in showers, lowering kitchen counters, and adding built-in scald protection)
• Residential Personal Care (Safety Enhancements): Sourcing and mounting non-structural barrier removals to secure a stable living setting (installing grab bars, handrails, anti-slip flooring materials, outdoor threshold leveling, and emergency backup alert devices)

2. Regulations

• Oklahoma Administrative Code (OAC) Rule 317:40-5-101 (DDS Architectural Modifications Policy)
• Oklahoma Administrative Code (OAC) Rule 317:35-17-3 (ADvantage Waiver Environmental Modification Scope)
• Oklahoma Statutes Title 59, § 1001 et seq. (Oklahoma Construction Industries Board Statutes)
• Federal HCBS Settings Final Rule (42 CFR § 441.301)

3. Licensing or Certification

Providers must maintain appropriate structural credentials from the Oklahoma Construction Industries Board (CIB), such as a licensed electrical, plumbing, or mechanical contractor registration, or operate as a credentialed general contractor. The business entity must also secure formal specialty vendor approval from the Oklahoma Department of Human Services (OKDHS) prior to portal contracting.

4. Responsible State Agency

The Oklahoma Health Care Authority (OHCA) administers the SoonerCare (Medicaid) program and controls the centralized contracting database. The Oklahoma Department of Human Services (OKDHS) Developmental Disabilities Services (DDS) and Aging Services (ADvantage) divisions review structural designs, organize property surveys, and grant individual project authorizations.

5. Application Process

Agencies apply for specialty vendor clearance through the OKDHS DDS or ADvantage Resource Development units. Following structural capability approval, the business executes its formal Medicaid contract digitally through the online Oklahoma SoonerCare Provider Portal under the Environmental Accessibility Adaptations specialty code.

6. Required Documentation

• Oklahoma Secretary of State business registration (Articles of Organization/Incorporation)
• Federal EIN and a Type 2 Organizational National Provider Identifier (NPI)
• Proof of active Oklahoma Construction Industries Board (CIB) license or verified subcontractor credentials
• Comprehensive EAA Policy and Procedure Manual (covering property evaluation, bid frameworks, ADA code adherence, and post-work warranties)
• Certificates of commercial general liability (minimum $1,000,000 policy), substantial property bonding, and workers' compensation insurance
• OSBI background check clearances for all field crew, structural installers, and estimators

7. Timeline for Approval

The end-to-end credentialing and billing activation timeline generally spans 3 to 5 months. Delays are typically linked to policy revisions, regional OKDHS vendor onboarding queues, and technical credential syncing inside the SoonerCare portal.

8. Pre-Application Process

Before initiating state applications, companies must establish a legal corporate structure with the Oklahoma Secretary of State, purchase necessary liability and performance bonds, clear corporate banking channels, and form relationships with licensed tradespeople (plumbers/electricians) to fulfill multi-faceted remodeling tasks.

9. Pre-Application Training

Designated project coordinators and billing agents must complete state-led Medicaid navigation modules. Staff must master the specific OKDHS bid submission rules and understand documentation protocols, including pre- and post-modification photo logs prior to bidding on waiver assignments.

10. Additional Notes

• Homeowner Authorization: Modifications cannot begin without written, notarized consent from the property owner, alongside a formal state commitment that the waiver participant plans to occupy the home for at least five (5) years
• Seven-Year Cap: Under OAC 317:40-5-101, modifications through DDS waivers are restricted to a maximum of two different residences within any seven-year period per participant
• Excluded Work Categories: Waiver funds explicitly prohibit structural additions that change the home's total square footage, cosmetic upgrades, routine roof repairs, or the installation of central heating and air conditioning systems
• Post-Work Verification: Final billing claims are strictly withheld until an official OKDHS Resource Development specialist physically inspects the completed construction to verify compliance with ADA standards and state building codes
