Wyoming - Home Modification 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 providers of Environmental Modifications under the Community Choices, Comprehensive, and Supports Waivers. Providers must first secure access to the Wyoming Health Provider (WHP) portal to initiate the certification process before enrolling in the Discover Your Provider (DyP) Medicaid system.

Approval requires the applicant to hold applicable local contractor licenses and building permits for the specific structural changes being made. The state does not impose a Certificate of Need, competitive procurement (RFP), or closed network moratorium on Environmental Modification providers, allowing any qualified contractor who passes the multi-step background screening and completes HCBS training to apply.

1. Service Definition and Scope

In Wyoming, this service is officially designated as Environmental Modifications under Chapter 44 of the state's Medicaid rules. It encompasses assessed, permitted, and inspected structural changes to a participant's residence that are necessary to ensure their health, welfare, and safety, or to enable them to function with greater independence in the home.

The scope of Environmental Modifications excludes improvements that are of general utility or add to the total square footage of the home. All modifications must be directly linked to the participant's assessed needs and require prior authorization based on competitive bids.

2. Regulatory and Oversight Agencies

The Wyoming Department of Health (WDH) Home and Community-Based Services (HCBS) Section is the primary regulatory body responsible for certifying Environmental Modification providers. They manage the initial application, background screenings, and ongoing compliance for waiver services.

Medicaid provider enrollment and financial oversight are managed by HHS Technology Group, which operates the Discover Your Provider (DyP) portal on behalf of Wyoming Medicaid.

3. Gatekeeping Prerequisites: Who Can Even Apply

Wyoming does not require a Certificate of Need (CON), Facility Need Review, or regional office sponsorship to become an Environmental Modification provider. There are no closed networks, moratoria, or mandatory managed care subcontracting requirements blocking new applicants.

The primary structural precondition is that the applicant must be a legally established business entity capable of performing construction work in Wyoming. Providers must hold any required local municipal or county contractor licenses and be able to pull building permits in the jurisdictions where they intend to operate.

4. Licensure and Certification Requirements

Wyoming does not issue a distinct state-level "Home Modification License" through a health facility licensing board. Instead, providers must obtain HCBS Provider Certification directly from the WDH HCBS Section.

To achieve certification, applicants must request access to the WHP portal, complete required HCBS provider training, and submit a complete application within 90 days of initiation. The application must demonstrate the provider's capacity to adhere to Chapter 44 rules, including obtaining necessary permits and inspections for all work.

5. Medicaid Provider Enrollment

After receiving HCBS Certification, the provider must enroll in Wyoming Medicaid using the Discover Your Provider (DyP) portal. This step links the provider's National Provider Identifier (NPI) and tax information to the state's MMIS for payment.

Providers must sign the Wyoming Medicaid Provider Agreement and undergo re-enrollment every five years. The enrollment process requires the upload of the HCBS Certification letter and verification of banking information for electronic funds transfer.

6. Staffing, Training and Background Checks

All owners and staff who will have direct contact with waiver participants must complete a multi-step background screening process before the HCBS application is submitted. This includes state and national criminal history checks.

Providers must also complete mandatory HCBS training modules covering incident reporting, participant rights, and waiver rules. Because Environmental Modification is a specialized service, the actual construction work must be performed by individuals with appropriate trade skills, though the state does not mandate specific clinical degrees for this provider type.

7. Documentation, Policies and Records

Environmental Modification providers must maintain comprehensive records for each project. This includes the initial written bid, the participant's assessed need documentation provided by the case manager, and all local building permits.

Upon completion of the modification, the provider must retain copies of the final local building inspection or, in jurisdictions without local inspectors, a signed statement of completion and satisfaction from the participant and case manager.

8. Billing, Rates and Claims

Environmental Modifications are not billed on a standard fee schedule or hourly rate; instead, they are reimbursed based on the authorized bid amount. The case manager must submit the provider's bid for prior authorization before any work begins.

Once the work is completed and inspected, the provider bills Wyoming Medicaid through the MMIS portal using the specific procedure code authorized on the participant's service plan. Providers cannot bill for modifications that exceed the waiver's lifetime or annual cap without special exception approvals.

9. Approval Sequence and Timeline

The approval sequence begins with requesting access to the WHP portal, which typically takes up to 48 hours for WDH approval. Once access is granted, the applicant completes background checks and training, then compiles and submits the application within the 90-day window.

After HCBS Certification is awarded, the provider submits their enrollment application through the DyP portal. The entire process, from initial portal request to active Medicaid billing status, generally takes 60 to 90 days depending on background check processing times.

10. Common Denials and Survey Findings

Applications for HCBS Certification are frequently delayed or denied if the applicant fails to complete the multi-step background screening prior to submission or allows the 90-day application window to expire.

During post-payment reviews or credentialing renewals, common findings include failure to maintain copies of local building permits, lack of final inspection documentation, or billing for work before the prior authorization was officially approved by the state.

11. Key Contacts and Resources

The WDH HCBS Credentialing team is the primary point of contact for certification questions and WHP portal assistance. They provide guidance on waiver rules, background checks, and application status.

For Medicaid enrollment, banking updates, and DyP portal technical assistance, providers must contact HHS Technology Group. Claims and billing inquiries are handled by the Wyoming Medicaid Provider Services help desk.
