Wyoming - Environmental Accessibility Service — Licensing, Medicaid Enrollment and Startup Requirements

Last reviewed: 2026-09-10

The Wyoming Department of Health (WDH) Home and Community-Based Services (HCBS) Section certifies Environmental Modification providers to deliver physical home adaptations under the Community Choices Waiver (CCW), Comprehensive Waiver, and Supports Waiver. These modifications, which include ramps, widened doorways, and roll-in showers, must be tied directly to an assessed need documented in the participant's person-centered service plan.

Approval requires applicants to first secure HCBS certification through the Wyoming Health Provider (WHP) portal before submitting a Medicaid enrollment application via the PRESM system. Applicants must hold applicable local contractor licenses and building permits, as Wyoming does not issue a distinct state-level license for this specific Medicaid service.

1. Service Definition and Scope

Environmental Modifications in Wyoming are defined as physical adaptations to the participant's home that are necessary to ensure the health, welfare, and safety of the individual or that enable the individual to function with greater independence in the home. These services are authorized under the state's HCBS waiver programs.

The service is strictly limited to modifications that address a specific assessed need. It explicitly excludes general home repairs, maintenance, or cosmetic upgrades that are not medically necessary.

2. Regulatory and Oversight Agencies

The Wyoming Department of Health (WDH) Division of Healthcare Financing oversees the administration of HCBS waivers and provider certification. Multiple distinct portals are used for credentialing, enrollment, and billing.

Providers must interact with the WDH HCBS Section for initial certification and the state's fiscal agents for Medicaid enrollment and claims processing.

3. Gatekeeping Prerequisites: Who Can Even Apply

Wyoming does not utilize a Certificate of Need, closed network, or RFP procurement process for Environmental Modification providers. Any entity meeting the general contractor qualifications and background check requirements may apply.

The mandatory structural precondition is that an applicant must first obtain HCBS Certification via the WHP portal; the state's Medicaid enrollment vendor (PRESM) will not accept a Medicaid provider application for waiver services without this prior WDH certification.

4. Licensure and Certification Requirements

Wyoming does not issue a distinct state-level "Environmental Modification" license. Instead, providers must meet general contractor requirements, adhere to local building codes, and obtain HCBS certification from WDH.

Providers must ensure that all structural modifications comply with municipal or county permitting requirements and pass local inspections where applicable.

5. Medicaid Provider Enrollment

After receiving HCBS certification, providers must enroll as a Wyoming Medicaid Provider through the HHS Technology Group (PRESM) Provider Enrollment system. This step generates the provider's active Medicaid billing ID.

Providers must sign the Wyoming Medicaid Provider Agreement and ensure they select the correct PRESM Provider Type corresponding to HCBS waiver services.

6. Staffing, Training and Background Checks

All HCBS providers in Wyoming must pass a multi-step background screening process before certification is granted. This includes state and national checks.

Providers must also complete mandatory WDH training modules and understand their legal obligations as mandatory reporters of abuse, neglect, and exploitation.

7. Documentation, Policies and Records

Environmental Modification providers must maintain detailed records of all bids, local permits, and project completion sign-offs. These documents are subject to audit by WDH.

Before work begins, providers must submit itemized bids to the participant's case manager for approval and inclusion in the service plan.

8. Billing, Rates and Claims

Claims for completed environmental modifications are submitted through the Benefits Management System (BMS) portal operated by Acentra. Reimbursement is based on the authorized bid amount.

Modifications are subject to waiver-specific financial caps, and the exact service must be prior-authorized in the participant's approved service plan before any work commences.

9. Approval Sequence and Timeline

The approval process begins with requesting access to the WHP portal, followed by the submission of the HCBS certification application. Once certified, the provider applies for Medicaid enrollment via PRESM.

Applications in the WHP portal that remain unsubmitted or inactive for 90 days are automatically canceled by the system.

10. Common Denials and Survey Findings

Applications are frequently delayed or denied due to administrative errors, such as failing to follow strict file naming conventions in the WHP portal or submitting incomplete background check forms.

For active providers, common audit findings include failing to retain copies of local building permits or failing to complete the mandatory 5-year Medicaid re-enrollment.

11. Key Contacts and Resources

Providers should direct certification questions to the WDH HCBS Credentialing Team and enrollment questions to the PRESM help desk.

Technical assistance for the various portals is handled by their respective vendors.
