California Regional Center and HCBS Waiver Help: Eligibility, Appeals, and Official Contacts
California Regional Center and HCBS Waiver Help
Plain-language starting point for Californians seeking developmental-disability services, HCBS waiver information, or help challenging a decision.
First: protect your private information
Do not send ABI Resources a Social Security number, Medi-Cal number, diagnosis, medical record, financial record, or Notice of Action. Use the official secure process given by the responsible California agency.
If someone is in immediate danger, call 911. For a medical emergency, use emergency services.
Start here in six steps
Find the regional center for the person’s home area. California has 21 regional centers. Use the official California DDS Regional Center Directory.
Call before sending personal health information. Ask the regional center how to transfer records securely.
Request an intake and eligibility assessment. There is no charge for the regional center’s diagnosis and eligibility assessment.
Ask for every decision in writing. Keep the date, sender, deadline, reason, and the exact service or eligibility decision.
Use the correct appeal path. A regional center appeal is different from a Medi-Cal managed-care appeal or a Medi-Cal State Fair Hearing.
Request communication accommodations. Ask for plain language, large print, an interpreter, extra processing time, a support person, or another effective accommodation when needed.
Who may qualify for regional center services?
California DDS says eligibility is determined through diagnosis and assessment by a regional center. In general, the developmental disability must:
Begin before age 18.
Be expected to continue indefinitely.
Present a substantial disability.
Meet California’s legal definition.
A brain injury diagnosis by itself does not automatically establish regional center eligibility. The regional center evaluates whether the person meets the state definition. Infants, toddlers, and some children ages three or four have additional or provisional eligibility routes.
Official explanation: DDS Information About Regional Centers
What regional centers do
Regional centers are private nonprofit corporations under contract with the California Department of Developmental Services. They can provide or coordinate:
Eligibility assessment and diagnosis.
Individual planning and service coordination.
Help accessing services and supports.
Monitoring and advocacy related to developmental-disability services.
Most regional center services are free, but California lists limited exceptions. Regional centers also use services funded by other responsible programs, called generic resources, before paying for services they cannot legally fund.

California HCBS waiver: use the current identifier
The current federal record for California’s HCBS Waiver for Californians with Developmental Disabilities is CA 0336.R05.00. CMS lists it as approved on July 14, 2026, effective January 1, 2023, and expiring December 31, 2027.
Older documents may show a different control number. Always confirm the current federal record before relying on a number.

Regional center services and the waiver are not the same thing
A person does not have to be enrolled in the HCBS waiver to receive state-funded regional center services. The waiver is a Medicaid funding pathway with its own requirements.
The official California guide explains that waiver participation generally involves regional center eligibility, Medi-Cal rules, an applicable institutional level of care, a community living arrangement, and other program conditions. Ask the regional center and Medi-Cal to explain which route applies to the individual.

If you disagree with a regional center decision
A regional center sends a Notice of Action (NOA) when there is disagreement about eligibility or services. The NOA should state the reason, effective date, appeal rights, and include an Appeal Request form.
California’s official guide describes two important filing windows:
To try to keep current services in place during the appeal, file within 30 days of receiving the NOA and before the action takes effect.
A regional center appeal generally must be filed within 60 days of receiving the NOA.
The process can include an informal meeting, mediation, and a hearing. Follow the exact notice and current DDS instructions because deadlines and procedures can change.
The DDS Office of the Ombudsperson can explain the appeal process and forms:

Email: Ombudsperson@dds.ca.gov
The Office of Clients’ Rights Advocacy can provide rights information and may assist with appeals:
Phone: 800-776-5746
TTY: 800-719-5798
If the problem is a Medi-Cal decision
Do not use the regional center appeal route for every Medi-Cal issue.
For a Medi-Cal managed-care service denial, California says to appeal to the health plan within 60 days of the Notice of Action. If the plan does not resolve it, a State Fair Hearing may be available.
For fee-for-service Medi-Cal, eligibility, or county action, the hearing route and deadline may be different.
The notice controls the safest next step.

Accessibility and communication rights
For regional center appeals, California’s guide states that people have the right to information in a language they know and understand and to an effective, accurate, neutral interpreter. For Medi-Cal State Fair Hearings, California offers free language help and reasonable disability accommodations.
When contacting an agency, a person can say:
I have a disability that affects reading, memory, processing, or communication. I am requesting an effective accommodation and information in plain language. Please confirm the deadline and next step in writing.
