Maine - I/DD Services — Licensing, Medicaid Enrollment and Startup Requirements

Last reviewed: 2026-09-10

The Maine Department of Health and Human Services (DHHS), through the Office of Aging and Disability Services (OADS), administers I/DD services under the MaineCare Benefits Manual Section 21 (Comprehensive Waiver) and Section 29 (Support Waiver). Providers must obtain a Home and Community Support Services Agency license from the Division of Licensing and Certification (DLC) and enroll via the MaineCare Health PAS Portal.

Effective April 13, 2026, OADS implemented a temporary pause on all initial provider applications for Sections 21 and 29 to manage high volumes and prioritize oversight of existing providers. When the application window is open, prospective agencies must first pass the OADS provider application review before applying for DLC licensure and finalizing MaineCare enrollment.

1. Service Definition and Scope

Maine divides adult I/DD waiver services into two primary MaineCare Benefits Manual categories: Section 21 (Comprehensive Waiver) for individuals requiring extensive residential and community supports, and Section 29 (Support Waiver) for individuals living with families or independently who need day, employment, or community supports. OADS is also transitioning toward a consolidated Lifespan waiver.

Eligible MaineCare members may only receive services under one waiver benefit at a time, and providers must be approved for the specific waiver section they intend to bill.

2. Regulatory and Oversight Agencies

Oversight is divided among three primary DHHS divisions. OADS manages the waiver programs and approves initial provider applications, DLC handles facility and agency licensure, and the Office of MaineCare Services (OMS) manages Medicaid billing and enrollment.

Providers must interact with all three divisions sequentially to become fully approved and operational.

3. Gatekeeping Prerequisites: Who Can Even Apply

Maine strictly controls the entry of new I/DD waiver providers through administrative application pauses. Before a provider can apply for licensure or MaineCare enrollment, they must submit and pass an initial application directly to OADS.

Without an approved OADS application, the Division of Licensing and Certification will not process a Home and Community Support Services Agency license for waiver services.

4. Licensure and Certification Requirements

Providers of I/DD services must be licensed as Home and Community Support Services Agencies under 10-144 CMR Chapter 108. The DLC processes these applications through an online system, requiring extensive organizational documentation and physical site inspections for residential or day program locations.

The initial license application requires a fee and detailed program descriptions for every service type the applicant intends to provide.

5. Medicaid Provider Enrollment

After obtaining OADS approval and DLC licensure, agencies must enroll as MaineCare providers through the Office of MaineCare Services. This is completed via the MaineCare Health PAS Portal, which interfaces with the Maine Integrated Health Management Solution (MIHMS).

Providers must define their specific service locations within the portal before they can begin receiving waiver members.

6. Staffing, Training and Background Checks

Maine requires strict credentialing and background screening for all direct care workers supporting Section 21 and 29 members. Staff must complete state-mandated training modules before providing unsupervised care.

Agencies are responsible for maintaining ongoing in-service training to ensure employees maintain their skills and knowledge per Chapter 108 rules.

7. Documentation, Policies and Records

Chapter 108 and MaineCare Benefits Manual rules require agencies to maintain comprehensive policy manuals and member records. OADS utilizes an electronic record system called Evergreen for case management and service planning.

Providers must align their internal documentation with the member's Personal Plan and adhere to strict incident reporting protocols.

8. Billing, Rates and Claims

Reimbursement for I/DD services is governed by the MaineCare Benefits Manual and processed through MIHMS. Rates are standardized by DHHS and vary based on the specific service code, staffing ratio, and waiver section.

Services must be prior-authorized by the Clinical Review Team (CRT) before claims can be successfully submitted.

9. Approval Sequence and Timeline

The end-to-end approval process is sequential and currently gated by the OADS application pause. When active, the process moves from OADS programmatic approval to DLC licensure, followed by OMS enrollment and final OADS onboarding.

Providers cannot begin delivering services or billing MaineCare until all steps, including the final onboarding meeting, are complete.

10. Common Denials and Survey Findings

Applications and site surveys frequently face delays or denials due to incomplete documentation or failure to meet physical site standards. During the current pause, any initial application submitted to OADS will be automatically rejected.

DLC surveyors closely scrutinize staff training records and physical plant safety during initial and renewal inspections.

11. Key Contacts and Resources

Prospective providers should monitor the OADS and DLC websites for updates on the application pause and rule changes. The HCBS Provider Application Portal and MaineCare Health PAS Portal are the primary systems for interacting with the state.

Direct questions regarding the waiver provider application process should be routed to the OADS provider email.
