How to start an IOP in Delaware: the DSAMH license, the provisional period and the steps

Who wrote this, honestly

We're Texas operators: we run a licensed Texas outpatient program, PHP through outpatient, and built our own EHR to run it. When we help an owner open in another state, the first task on that client's roadmap is "apply for your state's SUD treatment program license", and the work behind it is finding the state's rule and checking it against the agency's current text. This guide is that check for Delaware, and it's the same work our IOP / PHP Program Launch does for a client opening outside Texas. Where we couldn't confirm a detail, we left it out or told you who to ask.

Delaware at a glance

Question	Delaware's answer
Who licenses an SUD IOP	DSAMH, Department of Health and Social Services (DHSS), through its Provider Enrollment unit
Statute and rule	16 Del. C. chapter 22 (section 2208, licensing; section 2209, operating without a license) and 16 Del. Admin. Code 6001, Substance Abuse Facility Licensing Standards
License type	ASAM Level 2.1 intensive outpatient is its own license type; DSAMH also lists a combined outpatient and IOP license
License term	Provisional first (DSAMH policy describes a 180-day initial period), then a full license of up to two years when DSAMH finds substantial compliance
Application fee	The DSAMH application form lists a $15 non-refundable fee per licensure application, one application per program and location; certification-only applications carry no fee
Medicaid	A separate DSAMH Medicaid certification; Diamond State Health Plan MCOs AmeriHealth Caritas Delaware, Delaware First Health and Highmark Health Options
Counselor credential	Licensed chemical dependency professional (LCDP), Board of Mental Health and Chemical Dependency Professionals, 24 Del. C. chapter 30
Brokering	6 Del. C. section 2502F bars kickbacks, bribes and split fees for patient referrals by health-care providers and facilities

Who needs a DSAMH license

DSAMH's Licensure and Certification Guidelines (policy DSAMH057), first issued October 24, 2024 and revised through July 2026, answer the question most new owners ask: does my practice need a license, or just my clinicians? The test it uses is whether you run a comprehensive, specialized SUD program, one that includes assessment, development of a treatment plan, treatment at an ASAM level of care, and referral and assistance as needed. An IOP meets that test by definition.

Your setup	DSAMH license?
Freestanding IOP (ASAM 2.1), with or without outpatient (1.0)	Yes. DSAMH057 lists ASAM 2.1 as its own license type and maps it to Medicaid taxonomy 261QR0405X
Medical or mental health practice prescribing buprenorphine (office-based treatment)	Not on its own. DSAMH's buprenorphine prescriber policy (DSAMH024) says practitioners with DEA Schedule III authority can prescribe without DSAMH licensure, and practices that refer out for counseling and case management are typically excluded
That same practice adding counseling, groups and case management	Yes. Once an office-based practice expands to comprehensive SUD treatment, it needs a DSAMH license
Mental health-only practice	The SUD license doesn't apply; ask DSAMH which certification you need if you'll bill Medicaid for behavioral health services

Before you name your program, look at DSAMH's licensed provider list. It shows how existing programs are licensed (for example, "Intensive Outpatient Treatment Services ASAM Level 2.1") and who already operates near the site you're considering. For how intensive outpatient differs from partial hospitalization and standard outpatient, see IOP vs. PHP vs. outpatient.

The rules to read

Rule or document	What it covers
16 Del. C. chapter 22	The Substance Abuse Treatment Act: section 2208 (licensing of treatment facilities, regulations) and section 2209 (violations, including injunctions against unlicensed operation)
16 Del. Admin. Code 6001	The Substance Abuse Facility Licensing Standards: licensing, client rights, records and program standards, including the qualifications for the administrator (section 6.1.1) and the clinical director (section 6.1.2)
DSAMH057	Licensure and certification guidelines: which practices need a license, and the table of ASAM level-of-care license and certification types with taxonomy codes
DSAMH020	Path to full licensure or certification: provisional licenses, corrective action plans, extensions
DSAMH Certification and Reimbursement Manual	Medicaid certification standards and reimbursement, organized by ASAM level, with its own ASAM 2.1 section
6 Del. C. chapter 25F	Delaware's patient brokering ban

Several older versions of 6001 and the DSAMH policies are still online, including proposed revisions from 2010 and 2015, so read the version DSAMH currently posts. Our launch package builds the policy manual as a crosswalk: every requirement in 6001, the certification manual's ASAM 2.1 section and your accreditor's standards matched to a policy, form or record. That's the same way we'd build a policy and procedure manual for a Texas program.

Provisional to full: the path

Delaware doesn't hand a new program a full license on day one. DSAMH's path to full licensure policy (revised October 29, 2025) lays out the sequence:

Stage	What happens	What it means for you
1. Complete application	A new provisional license or certification starts with a complete application and every required document	Incomplete packets stall. Have the policy manual, program description, staffing plan and site documents done before you file
2. Provisional period	Provider Enrollment supports the organization with technical assistance through the initial provisional period (180 days), including help preparing for the audit and a site visit if you ask	Ask for the site visit. It's free feedback before the audit that counts
3. Audit and corrective action	A program on a provisional license submits a corrective action plan (CAP) within ten business days for DSAMH approval; the license depends on carrying out and sustaining the CAP	Ten business days is short. Assign an owner to each finding the day the report arrives
4. Extension, if needed	The policy allows an extension of 90 days or less, depending on the CAP and how serious the deficiencies are	Treat it as a safety net, not a plan
5. Full license	DSAMH's license frequency schedule policy (DSAMH058) allows a full license of up to two years when the program is in substantial compliance	Calendar the renewal and keep charts audit-ready; our chart audit checklist helps

The audit reads your charts, so the provisional period is when your documentation habits get set. Run an internal review before DSAMH arrives; our mock survey ($6,500) does the same thing against an accreditor's standards.

The application and fee

• One form for license and certification. DSAMH's license and certification application covers both, with a separate application for each program and each location.
• The fee. The form lists a $15 non-refundable fee for licensure applications; certification-only applications don't carry one. Confirm the amount on the current form before you file.
• Where it goes. The form directs completed applications and documents to DSAMH Provider Enrollment by email, at the address printed on the form.

The state fee is the smallest number in the project. Rent, staff and build-out before your first claim pays are the big ones; our guide to what it costs to start an IOP walks through them. Want the license work done for you? It's part of the program launch package, or $7,500 on its own as our state facility license application service.

Counselors and staffing

• Administrator and clinical director. 6001 sets qualifications for both positions (sections 6.1.1 and 6.1.2). Read them before you post the jobs; the clinical director's credentials are the ones DSAMH looks at first.
• The LCDP. Delaware licenses addiction counselors as licensed chemical dependency professionals through the Board of Mental Health and Chemical Dependency Professionals. 24 Del. C. chapter 30, subchapter III bars anyone without the license from calling themselves an LCDP.
• How someone qualifies. Under 24 Del. Admin. Code 3000-4.0, licensure is by certification: a NAADAC NCAC or MAC, the Delaware Certification Board's CADC, or another certification the board accepts. The applicant needs a master's degree (transcript sent straight from the school) and 3,200 hours of counseling experience over at least two years, including 1,600 supervised hours, at least 1,500 of them in direct chemical dependency counseling. Licensure by reciprocity is available to LCDPs from other states.
• Mental health clinicians. Plan a licensed clinician who can diagnose co-occurring conditions; the same board licenses Delaware's professional counselors and marriage and family therapists.
• Every hire gets checked against the federal OIG exclusion list; ask DSAMH which state background checks it requires.

We build personnel files from our staff credential file checklist and add each state's items. In Delaware, that means the underlying certification behind each LCDP, since the license depends on it.

Delaware Medicaid and the MCOs

• Certification is a separate step. DSAMH issues Medicaid certifications for behavioral health programs alongside licenses, and DSAMH057 maps each license type to its certification and to the matching section of the certification and reimbursement manual. Ask for both in the same application.
• Three plans. Delaware Medicaid runs mainly through the Diamond State Health Plan, administered by the Division of Medicaid and Medical Assistance (DMMA). The state contracts with three MCOs: AmeriHealth Caritas Delaware, Delaware First Health and Highmark Health Options. The current contracts took effect January 1, 2023, for five years with three optional one-year extensions, so watch for a new procurement before you rely on the list.
• Medicare pays for IOP and PHP only through hospitals, community mental health centers and a few other provider types, so most freestanding programs plan without it (CMS 2024 outpatient rule).

Our credentialing service handles Medicaid enrollment, MCO credentialing and facility contracts in any state, and Medicaid enrollment is $500 per clinician. Commercial plans want a facility packet too; getting insurance contracts for a treatment center explains it. Before every admission, verify benefits and authorization; the prior authorization guide covers what each plan asks for.

Chapter 25F, Delaware's brokering law

Delaware passed its patient brokering ban as Senate Bill 32, signed August 14, 2019. Now 6 Del. C. section 2502F, it makes it unlawful to offer or pay a kickback, bribe or split fee to induce a referral to a health-care provider or facility, to solicit or receive one in return for a referral, or to aid or participate in either. It isn't limited to addiction treatment. Section 2503F exempts arrangements the federal Anti-Kickback Statute (section 1128B of the Social Security Act) doesn't prohibit. The federal Eliminating Kickbacks in Recovery Act (18 U.S.C. 220) applies on top. In practice: pay marketers a salary, never per admission, and run any referral relationship past your attorney. Our guides to patient brokering laws and marketing a treatment center explain where the lines are.

The steps, in order

1. Define the program: ASAM 2.1 alone or with 1.0 outpatient, adults or adolescents, and whether you'll prescribe MAT on site.
2. Form the business with the Delaware Division of Corporations, get the EIN and the organization NPI (taxonomy 261QR0405X matches the ASAM 2.1 license), and line up a health-care attorney and CPA.
3. Find a site local zoning allows in New Castle, Kent or Sussex County, check it against DSAMH's licensed provider list, and lease with a way out.
4. Write the policy manual from 6001 and the certification manual's ASAM 2.1 section, plus 42 CFR Part 2 and HIPAA.
5. Hire the administrator and clinical director against 6001's qualifications, then LCDPs and a licensed clinician for diagnosis, and log every credential's end date.
6. File the DSAMH license and certification application, one per program and location, with the fee.
7. Set up the EHR before the audit: Cima's IOP and PHP plan keeps ASAM levels of care, group notes with each member's entry, attendance and authorizations in one place.
8. Use the provisional period: ask for the technical-assistance site visit, audit your own charts, and answer any CAP within ten business days.
9. Enroll with Delaware Medicaid and contract with the three MCOs, plus the commercial plans your clients carry.
10. Move to the full license and renew on schedule, with drills and chart reviews on the compliance calendar.

Questions

Do you need a license to open an outpatient rehab in Delaware?

Yes. 16 Del. Admin. Code 6001, under 16 Del. C. chapter 22, says no organization may operate a substance abuse treatment facility in Delaware without a DSAMH license. DSAMH lists ASAM Level 2.1 intensive outpatient as its own license type.

Who issues substance use treatment licenses in Delaware?

The Division of Substance Abuse and Mental Health (DSAMH) in the Department of Health and Social Services, through its Provider Enrollment unit. DSAMH also issues the Medicaid certifications behavioral health programs need to bill Medicaid.

How long does a provisional DSAMH license last?

DSAMH's path to full licensure policy describes an initial provisional period of 180 days, with technical assistance from Provider Enrollment, a corrective action plan due within ten business days of findings, and a possible extension of 90 days or less. A full license can run up to two years.

Does a buprenorphine prescriber need a DSAMH license?

Not just to prescribe. DSAMH's policy says practitioners with DEA Schedule III authority can prescribe buprenorphine without DSAMH licensure. A practice that expands into comprehensive SUD treatment, such as counseling, groups and case management, needs a license.

Does Delaware have a patient brokering law?

Yes. 6 Del. C. section 2502F, enacted in 2019 as Senate Bill 32, bars kickbacks, bribes and split fees for patient referrals to health-care providers and facilities, with an exception in section 2503F for arrangements the federal Anti-Kickback Statute allows.

Can a Texas company help with a Delaware program?

Yes, if it's honest about how. We run a Texas program, so in Delaware we work from 6001, DSAMH's policies, the certification manual and the MCOs' requirements, check each against the current text, and tell you where DSAMH, DMMA, the plans or your attorney has the final word. We don't guarantee a license, contract or date.

Want accreditation in the same project? Program Launch + Accreditation is $54,500. Or book a free 30-minute call and we'll walk through what Delaware will ask of you.

Cima Consulting isn't a law firm or an accounting firm. Delaware agencies make their own decisions; we don't guarantee approvals, rates or dates. Never pay or accept anything of value for patient referrals: 6 Del. C. chapter 25F and federal law (EKRA and the Anti-Kickback Statute) both apply.
