Maryland - Home Modification Service — Licensing, Medicaid Enrollment and Startup Requirements

Last reviewed: 2026-09-10

Maryland's Developmental Disabilities Administration (DDA) and the Office of Long Term Services and Supports (OLTSS) fund Environmental Accessibility Adaptations (Home Modifications) through the Community Pathways and Community Options waivers.

Approval requires an active Maryland Home Improvement Commission (MHIC) contractor license before Medicaid enrollment via the ePREP portal is permitted.

1. Service Definition and Scope

In Maryland, Home Modifications are officially termed Environmental Accessibility Adaptations under the Medicaid waiver programs. These are physical adaptations to the participant's home required by their person-centered plan to ensure health, welfare, and safety, or to enable greater independence.

The scope includes ramps, grab bars, doorway widening, and specialized bathroom modifications. It strictly excludes general home maintenance, carpeting, roof repair, or modifications that add square footage to the property.

2. Regulatory and Oversight Agencies

The Maryland Department of Health (MDH) oversees all Medicaid waiver programs, with specific operational authority delegated to the Developmental Disabilities Administration (DDA) and the Office of Long Term Services and Supports (OLTSS).

Because Maryland does not issue a distinct healthcare license for home modification providers, the primary regulatory body for the physical work is the Maryland Department of Labor's Home Improvement Commission (MHIC).

3. Gatekeeping Prerequisites: Who Can Even Apply

Maryland does not utilize a Certificate of Need (CON), Request for Proposals (RFP), or closed network moratorium for Environmental Accessibility Adaptations. There is no requirement to affiliate with a specific managed care organization or designated lead agency to provide this service under the fee-for-service waivers.

The absolute structural precondition blocking an applicant is the requirement to hold an active Maryland Home Improvement Commission (MHIC) contractor license. Medicaid will not accept an ePREP enrollment application for this service type without proof of this specific credential.

4. Licensure and Certification Requirements

Maryland does not have a specific Medicaid healthcare license for home modification providers. Instead, providers must meet the state's commercial contracting requirements through the Maryland Home Improvement Commission (MHIC).

To obtain an MHIC license, the applicant must pass the MHIC contractor exam, prove two years of relevant experience, and submit financial solvency documentation.

5. Medicaid Provider Enrollment

Once the MHIC license is secured, providers must enroll in Maryland Medicaid through the electronic Provider Revalidation and Enrollment Portal (ePREP).

Providers enroll as an Atypical Provider (no NPI required) under the specific waiver provider type for Environmental Accessibility Adaptations. The application requires uploading the MHIC license, W-9, and SDAT certificate of good standing.

6. Staffing, Training and Background Checks

Because home modification providers do not provide direct personal care, they are exempt from many of the intensive clinical training requirements applied to direct support professionals.

However, any personnel entering a waiver participant's home must pass a criminal background check, and the enrolled provider must ensure all subcontracted trades (e.g., plumbers, electricians) hold their respective Maryland occupational licenses.

7. Documentation, Policies and Records

Providers must maintain rigorous documentation for every modification project, starting with a detailed written bid that matches the occupational therapist's assessment.

Records must include before and after photographs, copies of all local building permits, and final county or municipal inspection approvals before the final claim is submitted.

8. Billing, Rates and Claims

Billing for Environmental Accessibility Adaptations is processed through the LTSSMaryland system. Services are reimbursed on a fee-for-service basis based on the approved bid amount, not a standardized state rate schedule.

Providers typically bill in milestones, such as a deposit for materials and a final payment upon completion, provided these milestones are explicitly authorized in the participant's service plan.

9. Approval Sequence and Timeline

The approval sequence is strictly linear. A provider cannot begin Medicaid enrollment until their commercial contracting credentials are fully secured.

The process begins with SDAT registration and MHIC licensure, followed by ePREP enrollment, and concludes with registration in the LTSSMaryland system to receive authorizations.

10. Common Denials and Survey Findings

Home modification providers are frequently cited or denied payment for failing to secure local building permits or failing to obtain final municipal inspections.

Another common issue is performing work that deviates from the occupational therapist's specifications without obtaining a revised prior authorization in LTSSMaryland.

11. Key Contacts and Resources

Providers should utilize the official state portals for licensure and enrollment. The ePREP portal handles all Medicaid enrollment actions, while the MHIC manages contractor licensing.

For waiver-specific policy questions, providers should contact the DDA Provider Relations team or the OLTSS provider support desk.
