How to Open an ABA Clinic in Maryland

Opening an ABA clinic in Maryland follows the same backbone as anywhere — entity, NPI, credentialing, Medicaid enrollment — with Maryland's own Medicaid program and rules layered on top. Here's the path.

The steps to open in Maryland

1Form your entity & get an EIN. Register your business in Maryland, obtain an IRS EIN, and prepare a W-9.

2Get your NPIs. A Type 1 NPI for each BCBA and a Type 2 NPI for the organization, free from NPPES.

3Secure liability insurance for the practice and rendering providers.

4Build & attest CAQH profiles for every provider — most commercial payers pull from CAQH.

5Enroll in Maryland Medicaid. Enroll with Maryland Department of Health (Medicaid) and any managed-care plans that administer behavior analysis benefits in Maryland.

6Credential commercial payers and confirm each contract's effective date before billing.

Maryland Medicaid

Medicaid is central to ABA access in most states. In Maryland, behavior analysis benefits are administered through the state Medicaid program. Confirm current provider-enrollment steps, covered codes, authorization rules, and whether services run through managed-care plans directly with the agency below.
