How to get insurance contracts for an IOP or PHP (2026)

The short version

A treatment program gets in network by applying to each insurance plan as a facility after its state license is issued (in Texas, the HHSC chemical dependency treatment facility license for an SUD program), and, for many commercial plans and TRICARE, after it's accredited. Expect about 90 days per plan once the application is complete. In order:

1. Get the state license first. Plans contract with a licensed facility, not with a plan to open one.
2. List the plans your future clients actually carry, and ask each one whether it requires accreditation for your levels of care.
3. Build one facility packet, kept current, and apply to each plan as an organization.
4. Prepare for a site visit, answer every request for more information fast, and follow up every two weeks.
5. Read the contract before you sign: the rate for each code, timely filing, termination and the effective date.
6. Get the effective date and provider ID in writing, load them, and bill that plan as in-network only from that date forward.

A program's contract is different from a clinician's. A therapist joins a network as an individual, usually through a CAQH profile. A program applies as a facility, with its license, its policies, its building and its organization's insurance, and it's paid a daily rate for each level of care. Some plans also credential the clinicians who work there; ask each one. If you're a clinician joining as an individual, start with our credentialing page instead.

When you can apply

In Texas, a program that treats substance use disorders needs an HHSC chemical dependency treatment facility license before it treats anyone (our guide to starting an IOP in Texas walks through it). The facility contracts come after that license. You can and should build the packet while the license is pending, but most plans won't take the application until you can attach the license.

Before you apply, have these settled, with the legal name spelled exactly the same on every one:

• The facility license, and for a mental-health-only program, written confirmation of what license, if any, Texas requires for it. Ask HHSC and your attorney.
• The organization NPI (Type 2) with a clinic or facility taxonomy, the IRS letter with your EIN, and a signed W-9.
• The building: certificate of occupancy and the fire marshal's inspection.
• The organization's general and professional liability certificates.
• Your levels of care, weekly schedule and admission criteria, because every plan asks what you offer and for whom.

Don't see a plan's members as in-network until that plan's contract is effective. Claims before the effective date usually deny, and a plan rarely backdates. Until then, see self-pay clients or ask for a single case agreement.

Which plans want accreditation first

Texas doesn't usually require accreditation for an IOP or PHP license, but many payers do before they'll contract. Ask each plan before you count on it, and plan your accreditation timeline around the plans you need most.

Plan type	Accreditation before contracting?	Notes
Commercial plans (for example BCBSTX, Aetna, Cigna's Evernorth, UnitedHealthcare's Optum)	Often, for IOP and PHP	Many contract with IOP and PHP programs only once they hold Joint Commission or CARF accreditation. Some will start the application and finish it when the letter arrives.
TRICARE	Yes	TRICARE's policy manual requires partial hospitalization programs and substance use disorder rehabilitation facilities (including IOPs) to be accredited by the Joint Commission, CARF, the Council on Accreditation or another accreditor the Defense Health Agency approves, and to sign a participation agreement. Apply through the regional contractor for your ZIP code.
Texas Medicaid and its managed care plans	Not usually the gate	SUD programs enroll with TMHP as a licensed chemical dependency treatment facility, then contract with each Medicaid managed care plan in their service area. Check which services Texas Medicaid pays your license type for first.
Medicare and Medicare Advantage	Usually moot	Medicare pays for PHP, and since 2024 IOP (CMS's 2024 outpatient rule), only through hospitals, community mental health centers and a few other provider types. Most freestanding programs can't bill Medicare for these levels. Medicare Advantage plans follow Medicare's rules here, so ask before counting on one.
VA Community Care Network	Ask the contractor	Apply to the regional contractor's network. Veterans need a VA referral and authorization before care starts.

Accreditors survey only once you're serving clients and have charts to review, so most programs open with Texas Medicaid plans, the commercial plans that don't require accreditation, self-pay and single case agreements. They add the plans that require accreditation after the survey. Send the accreditation letter to every plan the day it arrives. The Program Launch + Accreditation package carries a program all the way through that survey, and Comply publishes a Joint Commission behavioral health checklist and a CARF survey prep guide.

Which plans to go after

Each contract is real work for you and for the plan, so start with the plans that will fill your groups. Rank them on four things:

1. Who your future clients carry. Ask your referral sources (hospitals, detox units, therapists, EAPs) which cards they see most. If you already run an outpatient practice, your own benefits checks are the best data you have.
2. Whether the plan pays for your levels of care, and on which claim form. Some pay a daily rate on a CMS-1500 with HCPCS codes, some want a UB-04 with revenue codes.
3. Whether its network is open for facilities at your level of care in your county. If it isn't, see what to do when the network is closed.
4. Whether it requires accreditation for your levels of care (above).

Find out who actually manages the behavioral health benefit before you apply. Cigna's behavioral network is run by Evernorth, UnitedHealthcare's by Optum, and some Blue plans, Medicaid plans and employers use Carelon or Magellan. Applying to the medical plan when the behavioral health company runs the network wastes weeks. Quick VOB's guide to behavioral health carve-outs explains how to tell.

A typical Texas list, depending on your area:

• Commercial: Blue Cross and Blue Shield of Texas, Aetna, Cigna/Evernorth and UnitedHealthcare/Optum.
• Texas Medicaid and CHIP: TMHP enrollment first, then the managed care plans in your service area, such as Superior HealthPlan, Wellpoint, Molina, and local plans like Community Health Choice (Houston area), Parkland Community Health Plan (Dallas), Cook Children's (Fort Worth), Driscoll (Coastal Bend and the Valley) and El Paso Health. Plan line-ups change with HHSC contracts, so check HHSC's current list for your area.
• Marketplace: Ambetter from Superior HealthPlan and Oscar, where they sell plans in your county.
• Military and veterans: TRICARE once you're accredited, and the VA Community Care Network.

The facility application packet

Most delays come from a missing page, an expired certificate or a name that doesn't match the IRS letter. Build one folder and keep it current. Plans' forms differ, but they draw from the same list:

Item	What to watch
The plan's organizational application	Many run through Availity or the plan's own provider site. Ask for the facility or ancillary application, not the individual one.
State facility license	The exact levels of care and address on it must match what you're applying for.
Accreditation letter, if you have it	Include the survey report summary if the plan asks.
W-9, IRS EIN letter and Type 2 NPI	Legal name and address identical across all three and NPPES.
Liability insurance certificates	General and professional liability for the organization, at the limits each plan asks for.
Ownership and management disclosure	Who owns 5% or more, the officers and the managing employees, with an exclusion check on each.
Program description	Levels of care, hours a week at each, the schedule, ages served, admission and discharge criteria (ASAM-based for SUD), and how medication for addiction treatment is handled.
Staff roster and credentials	Program director, clinical director, medical director agreement, and each clinician's license and NPI.
Key policies	Often quality improvement, credentialing of staff, client rights and grievances, records and confidentiality (including 42 CFR Part 2), and emergency procedures.
Building documents	Certificate of occupancy and fire inspection.
CLIA certificate of waiver	If you do instant drug tests on site.
Voided check or bank letter	For direct deposit (EFT), in the organization's name.

Ask each plan two questions on the first call: does it also credential the clinicians who work in the program, and does it require accreditation first? Write down the rep's name, the date and the reference number. Then follow up every two weeks until there's a decision, and answer any request for more information the same week. That two-week follow-up is exactly what our facility credentialing service does for each plan, with every application's status in your client portal.

The site visit

Many plans visit a new facility before they contract. Plans use their own checklists, but treat it as a short version of a state or accreditation survey and have this ready:

• The license, certificate of occupancy, fire inspection and drill records on hand.
• A clean, accessible building: signage, exits marked, group rooms that fit your groups, private offices for individual sessions, and records and any medications locked.
• The policy manual, the intake packet, and a blank set of the forms you use for assessments, treatment plans, group notes and discharges.
• Someone who can walk the visitor through a client's day, from referral and benefits check to discharge and aftercare.

If you've already had charts reviewed the way a payer auditor reads them, the visit is easy. Comply's chart audit checklist is a good self-check.

Reading the contract before you sign

The first contract a new program is offered is usually the plan's standard agreement and fee schedule. Read it anyway. What you sign sets your rate, your deadlines and how you can get out for years. Have your health-care attorney review it; we give you the business questions to bring.

Term	What to check
Fee schedule, by code	Get the rate for every code you'll bill, in writing, as an exhibit: for example S0201 for PHP, H0015 for SUD IOP, S9480 for mental health IOP, or revenue codes 0912/0913 and 0905/0906 on a UB-04, plus assessments and individual sessions. "Our standard rates" with no numbers isn't a fee schedule.
What the daily rate includes	Whether psychiatric visits, assessments, drug tests and individual sessions are bundled into the per diem or billed separately.
"Lesser of" language	Many contracts pay the lesser of your billed charge or the fee schedule. Set your standard charges at or above your best contract rate so you never get paid less than the contract allows.
Timely filing	How many days you have to send a claim and a corrected claim. For state-regulated Texas insurers and HMOs, the law sets 95 days from the date of service, and a late claim forfeits payment (Texas Insurance Code §1301.102 and §843.337). Self-funded and other plans set their own limits in the contract. Put each plan's limit in your billing system.
Products and networks	Which of the plan's products you're joining: commercial, Medicare Advantage, Medicaid, marketplace. Some contracts sign you up for all of them, which you may or may not want.
Authorization and review rules	Which levels need prior authorization, how often concurrent reviews happen, and which criteria the plan uses.
Term, renewal and rate changes	How long it runs, whether it renews on its own, whether rates ever go up, and when you can ask to renegotiate.
Termination	How much notice either side must give without cause, what counts as cause, and what happens to clients in care when it ends.
Policy changes by notice	Most contracts let the plan change its provider manual. Know how much notice you get and where it's posted.
Audits and recoupment	How far back the plan can audit and take money back, and how you dispute it.
Effective date	The date you can bill in-network. Get it in writing, with your provider ID.

If the rates won't cover your cost of care, say so before you sign. Our guide to negotiating insurance rates covers what to bring and what's usually negotiable. You sign every contract yourself.

Loading the contract

A signed contract doesn't get you paid. Before the first claim:

1. Confirm the effective date and provider ID in writing. If the plan's directory or portal doesn't show you yet, call.
2. Add the plan to your clearinghouse with its payer ID, and enroll in ERA (electronic remittance) and EFT (direct deposit). Register for the plan's provider portal.
3. Load the plan in your EHR: the codes and claim form it wants, the contract rate for each, its timely filing limit and its authorization rules.
4. Move members from self-pay to the plan from the effective date forward, never before.
5. Check the first claim end to end, then match each payment to the contract rate. Work underpayments while they're small.

Cima EHR's Program plan handles the program side of this: levels of care, attendance and per diem billing, and authorizations with continued-stay reviews, for $399 a month for up to 25 clients.

How long it takes

Plan on about 90 days per facility contract after the license, and longer for the plans that require accreditation, since that clock starts after your survey. From a complete application to in-network, by kind of plan:

Plans	Typical time	Reads CAQH
Commercial plans Aetna, Cigna / Evernorth Behavioral Health, UnitedHealthcare / Optum Behavioral Health, Blue Cross and Blue Shield of Texas	45–120 days	Yes
Medicare (PECOS)	30–90 days	No
Medicare Advantage plans Humana (Medicare Advantage), Medicare Advantage plans	60–120 days	Yes
Texas Medicaid (TMHP)	30–60 days	No
Texas Medicaid and CHIP managed care plans Superior HealthPlan, Wellpoint Texas (formerly Amerigroup), Molina Healthcare of Texas, Community Health Choice and 9 more	60–120 days	Yes
Marketplace plans Ambetter (marketplace), Oscar Health (marketplace)	60–120 days	Yes
Behavioral health managers Magellan Healthcare, Carelon Behavioral Health (formerly Beacon Health Options)	60–120 days	Yes
Employee assistance and benefit networks ComPsych (EAP), Lyra Health, Spring Health	30–90 days	No
TRICARE and VA Community Care TRICARE, VA Community Care Network	60–120 days	No

These are typical ranges from our own work, not promises; plans set their own pace. First payments usually arrive about a month after the first clean claims, so budget several months of payroll and rent before insurance money arrives.

What to do while you wait

• Self-pay, priced honestly. Set self-pay rates and give every uninsured or self-pay client a good faith estimate before services, as the No Surprises Act requires.
• Single case agreements. For a client whose plan you're not in yet, ask the plan for a single case agreement at a rate agreed in writing before admission. Our single case agreement guide covers how to win one.
• Out-of-network benefits. Some PPO members have out-of-network benefits for your level of care. Verify them, get the authorization, and tell the client their cost in writing. The VOB checklist lists what to ask.
• Never borrow a contract. Billing your services under another program's contract, license or NPI misrepresents who gave the care and can be treated as fraud.
• Build your record. Track time from referral to admission, completion rates and a standard measure repeated over time. It's your case for the next contract and for better rates.
• Build referrals the legal way. Never pay or give anything of value for referrals: the Texas Patient Solicitation Act and the federal EKRA statute (18 U.S.C. 220) both forbid it.

Questions

Can a treatment program apply for insurance contracts before it's licensed?

You can prepare everything before the license is issued, but most plans won't accept a facility application until you can attach the state license. In Texas, an SUD program needs its HHSC chemical dependency treatment facility license first. Start the packet early so you can file with every plan the week the license arrives.

How long does it take an IOP or PHP to get in network?

About 90 days per plan after a complete application is a fair planning number, with a typical range of 60 to 120 days for most commercial and Medicaid managed care plans. Plans that require accreditation can't start until after your survey, which adds months. No one can promise a plan's dates.

Do we need Joint Commission or CARF accreditation to get insurance contracts?

Not for every plan. TRICARE requires it for PHPs and SUD programs including IOPs, and many commercial plans require it for IOP and PHP contracts. Texas Medicaid managed care plans generally contract with licensed facilities. Ask each plan on your list before you plan around it.

Can we use another program's contract until ours comes through?

No. A facility contract, license and NPI belong to one organization and the services it provides. Billing your care under someone else's numbers misrepresents who provided it. See self-pay clients or ask for single case agreements instead.

Will the plan make our contract effective retroactively?

Don't count on it. The plan sets the effective date, and backdating is rare. Bill a plan as in-network only from the effective date in writing.

What if the plan says its network is closed?

Ask for that answer in writing, with the reason and when to reapply, then ask for an exception based on access: distance, wait times, your level of care, languages and the clients you serve. Our guide to closed insurance networks walks through the letter and Texas network adequacy rules.
