How to add a level of care: PHP to an IOP, or IOP and PHP to a practice

Adding a level of care is the most common way a program grows, and the most common way it ends up seeing clients it can't bill for. The clinical side is the easy part. The state notice, the payer amendments and the authorization workflow are what decide whether the new level pays. Written by the team that runs a licensed Texas PHP, IOP and outpatient program.

Updated October 24, 2026. Not legal advice: rules change, so check the current rule with HHSC and talk to a health-care attorney. Cima Consulting isn't a law or accounting firm.

The short answer: a Texas program already licensed by HHSC as a chemical dependency treatment facility notifies HHSC licensing in writing before adding a new day treatment or outpatient service; it doesn't need a new license. A practice that isn't facility-licensed needs the full license before it runs a substance use IOP or PHP. Either way, each insurance plan has to add the level and its rate to your contract before you bill it, and that usually takes longer than the clinical build.

1. The Texas license step

  • Already licensed as a chemical dependency treatment facility? The change-in-status rule (26 TAC 564.405) asks a licensed facility to notify HHSC licensing in writing before adding a new day treatment or outpatient service, and to apply and get written approval first for residential, detoxification and added beds. HHSC uses Form 3207 for change-in-status applications, with the Form 3209 checklist. Send the notice before the first client at the new level, keep a copy, and check how HHSC lists the new service on your license.
  • Not licensed today? A Texas program that treats substance use disorders must be licensed by HHSC as a chemical dependency treatment facility before it treats anyone (Health and Safety Code chapter 464, 26 TAC chapter 564). For a practice adding its first SUD program, that's a full new license with an operational plan and inspection, and after filing you have 6 months to show HHSC the program meets the rules.
  • Mental health only? Texas licenses SUD treatment facilities and psychiatric hospitals; a freestanding mental health IOP run by licensed clinicians may not need a facility license. Confirm with HHSC and your attorney before you open, especially for PHP. If you'll also treat substance use as a primary service, you'll likely need the SUD license.
  • Adolescents? 26 TAC 564.905 keeps adults and adolescents separate in outpatient services and sets at least 15 hours a week for adolescent day treatment, including at least one hour of individual counseling; school attendance doesn't count.

2. Design the level: hours and schedule

Texas chapter 564 doesn't set minimum weekly hours for adult IOP or PHP. It requires treatment intense enough to meet each client's treatment-plan goals, with individualized planning, educational and process groups, and individual counseling (26 TAC 564.904, in chapter 564). The hour expectations come from the plans and from The ASAM Criteria:

  • Most payers expect about 20 hours a week for PHP and at least 9 hours a week for adult IOP. Read each plan's level-of-care guidelines; they decide what an authorization covers.
  • A PHP day is long. 26 TAC 564.1101 requires a meal break after five consecutive hours of scheduled activities, so build lunch into the schedule.
  • Admission, continued-stay and discharge criteria for the new level, by ASAM dimension, so every client's placement can be defended on review.
  • A group curriculum for the new level, each group tied to treatment-plan goals, plus the education topics chapter 564 requires (TB, HIV, hepatitis B and C, sexually transmitted infections, and tobacco).
  • Step-down paths. Decide where a PHP client goes next (your IOP) and where an IOP client goes (your outpatient or a partner). Continuity inside one program is the strongest argument you have with a utilization reviewer.

3. Staffing and space

  • Counselors: in a Texas SUD program, counseling is provided by or under qualified credentialed counselors (QCCs), and a QCC authorizes each admission in writing with the level of care (26 TAC 564.802). Work out the group sizes and hours per counselor for the new schedule before you hire.
  • Medical oversight: many plans expect PHP clients to have physician or psychiatric involvement, regular nursing assessment and medication management. Read each plan's PHP criteria and your medical director's agreement, and amend the agreement at fair market value for the added hours.
  • Credential every new hire before day one: license verification, OIG and Texas Medicaid exclusion checks, and a credential file a surveyor can pull. Some plans also credential the clinicians who work in a facility.
  • Space: a PHP day fills rooms for most of the day. Check group room capacity, a place to eat, and whether your certificate of occupancy covers the added use and headcount.
  • Update the policies: scope of services, admission criteria, staffing plan, the schedule and the emergency plan. Your accreditor will read them against what you do.

4. Payer contracts and rates

This is where most launches stall. A facility contract lists the services and rates it covers; a level that isn't on it isn't in network.

  • Ask each plan, in writing, what it needs to add the level: a contract amendment or new rate exhibit, a credentialing update, a site visit, or proof of accreditation. Many commercial plans contract for IOP and PHP only with accredited programs, and TRICARE requires accreditation (Joint Commission, CARF or COA).
  • Negotiate the rate before you launch. Our facility contract service handles the application, the amendment and the rate review checklist. Ask for the rate by code, the billing form (CMS-1500 or UB-04), whether it's per diem, and what's bundled into it.
  • Texas Medicaid: check which services Texas Medicaid and each managed care plan pay your license type for at the new level before you plan on it.
  • Medicare: 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 such as FQHCs and rural health clinics. Most freestanding programs can't bill Medicare for these levels.
  • Bridge with single case agreements. Until an amendment is effective, a single case agreement for one client, with the rate agreed in writing before admission, can let you serve that client.

Don't move a client "up" to the new level for a plan whose contract doesn't include it yet. The care may be right, but the claims will deny, and you can't bill the client for the difference on an in-network plan.

5. Authorizations and level changes

  • Each level is its own authorization. A step-down from PHP to IOP usually needs a new request, not an extension. Put the precertification and review rules for each plan and level in one place; Cima's program EHR keeps them on each client's episode and reminds staff before an authorization ends.
  • Document every level change. 26 TAC 564.804(k) requires a QCC-signed decision with the rationale and effective date, a revised treatment plan, and coordination with the receiving provider. The same note is what a payer reviewer wants to see.
  • Schedule concurrent reviews and draft the continued-stay note about five days before an authorization ends, citing the ASAM dimensions or the plan's criteria.
  • Verify benefits for the new level at admission. Deductibles, visit limits and prior authorization often differ between IOP and PHP. Quick VOB's guides cover the VOB checklist and prior authorization for behavioral health.

6. Billing codes

Programs commonly bill a daily rate. Each plan decides which codes and claim form it accepts, so confirm with every contract:

LevelCommon HCPCS (CMS-1500)Common revenue codes (UB-04)
PHPS02010912, 0913
SUD IOPH00150906
Mental health IOPS94800905

Set a standard daily fee for the new level at or above what your best-paying plan allows, and check that the hours documented each day support the day billed. A chart audit in the first month catches the gaps before a payer does.

7. Set up the EHR

Before the first client at the new level, the EHR should know about it:

  • The level of care on each client's episode, with the date it changed and the QCC sign-off.
  • A schedule of groups for the level, attendance by client, and hours per day that roll up to the per diem.
  • Each plan's code, rate and authorization rules for the level, with reminders before an authorization runs out.
  • Group notes where each client gets their own entry tied to their own plan goals.

Cima EHR for IOP and PHP programs does this: levels of care, group notes with each client's own entry, attendance, per diem billing, and authorizations with continued-stay reviews. The Program plan covers up to 25 clients in the program; see Cima EHR pricing.

The order to do it in

  1. Decide the level, schedule and who you'll serve. Check demand and each plan's rates for it.
  2. Ask each plan what it needs to add the level, and start the amendments. They take the longest.
  3. Write the admission criteria, curriculum, staffing plan and policy updates. Amend the medical director agreement.
  4. Send HHSC the written notice (or, if you're not licensed, apply for the license).
  5. Hire and credential staff. Set up the EHR, the fee schedule and authorization rules.
  6. Tell your accreditor about the new service and ask whether it needs a survey.
  7. Admit the first clients as each plan's amendment becomes effective, using single case agreements in between.
  8. Audit the first month's charts against what was billed.

Questions

Does adding PHP to my IOP need a new HHSC license?

For a facility already licensed by HHSC, 26 TAC 564.405 asks for written notice to HHSC licensing before adding a new day treatment or outpatient service, rather than a new license. A practice that isn't facility-licensed and adds a substance use program needs the license first. Confirm how HHSC will list the new service on your license.

Can I bill PHP under my existing IOP contract?

Only if the contract covers PHP. Most facility contracts list the services and rates they cover. Ask each plan for an amendment or new rate exhibit, and get the effective date in writing before you bill the new level.

How many hours a week does a PHP need in Texas?

Texas chapter 564 sets no weekly minimum for adult PHP or IOP. Most payers expect about 20 hours a week for PHP and at least 9 for adult IOP. Adolescent day treatment needs at least 15 hours a week under 26 TAC 564.905.

How long does adding a level take?

The clinical build can be done in weeks. The payer amendments usually take longer, often a few months per plan, and accreditation-only plans won't add the level until you're accredited.
