IOP vs PHP cost in Texas

IOP and PHP side by side

	Intensive outpatient (IOP)	Partial hospitalization (PHP)
Hours a week	At least 9 for adults (ASAM's intensive outpatient level is 9 to 19)	At least 20 (ASAM Level 2.5 and Medicare's PHP benefit)
A typical week	For example 3 hours a day, 3 days a week	For example 4 or more hours a day, 5 days a week
How the program bills	A daily rate (per diem) for each day you attend, for example HCPCS H0015 for substance use IOP	A daily rate for each day you attend, for example S0201 or H0035, or revenue code 0912 or 0913 on a hospital-style claim
Original Medicare	Part B: 20% of the Medicare-approved amount after the Part B deductible ($283 in 2026)	The same: 20% after the Part B deductible
Private insurance	Your plan's copay or coinsurance for each day, after any deductible, up to your out-of-pocket maximum; usually needs prior authorization	The same, and prior authorization is the rule
Texas Medicaid	Through your Medicaid health plan, at a licensed chemical dependency treatment facility in its network	Offered by health plans that choose to, in place of inpatient care

The hours are the real difference. Medicare prices IOP and PHP days from the same costs, one rate per setting and tier; what changes is how many hours you're in treatment and how many days a week you go. That's why a week of PHP, at five days, usually costs your plan, and you, more than a week of IOP at three.

What you pay, by coverage

• Private insurance. Your share is set by your plan, not the program: a copay or coinsurance for each day, after your deductible, until you reach your out-of-pocket maximum for the year. Under the federal parity law, a plan that covers substance use care can't make its copays, deductibles or prior authorization rules stricter than for medical and surgical care. Out of network, you may owe much more, or everything. See how to use insurance in Texas.
• Medicare. Original Medicare Part B covers IOP and PHP. After the Part B deductible ($283 in 2026) you pay 20% of the Medicare-approved amount, and in a hospital outpatient department or community mental health center you may owe a coinsurance for each day. A Medicare Advantage plan sets its own copays and network.
• Texas Medicaid. Substance use treatment is a Medicaid benefit, given by licensed chemical dependency treatment facilities. Most members are in a managed care health plan, which pays the program; PHP and adult IOP are offered by plans that choose to, as in-lieu-of services. Call the member services number on your card and ask what you'd owe.
• No insurance. Ask the program for its self-pay daily rate and whether it has a sliding-scale fee. Texas also pays for substance use treatment for adults whose income qualifies: the front door is an OSAR (Outreach, Screening, Assessment and Referral) in your region, or call 2-1-1.

Find out your cost before you start

1. Call your plan (the number on your card). Ask: is IOP or PHP for substance use covered; is this program in network; does it need prior authorization; what do I pay a day; how much of my deductible and out-of-pocket maximum is left.
2. Call the program. Ask them to verify your benefits, how many days a week you'd attend, how many weeks they expect, and what they charge self-pay or on a sliding scale.
3. Multiply it out. Your share for a day, times the days a week, times the weeks, stops at your out-of-pocket maximum. If you pay yourself, ask for a written Good Faith Estimate: under the No Surprises Act, providers must give one to self-pay patients.
