Running campaigns for treatment centers, we see a detox or residential admission from Google Ads or directories cost $2,000 to $5,000 in-network and $7,000 to $15,000 out-of-network. SEO brings the cost per admission down to anywhere from a few hundred dollars up to $2,000 to $5,000.
A VOB (verification of benefits) costs from a couple hundred dollars up to $2,000 in some out-of-network cases.
Rehab cost per admission at a glance
| Channel | In-network | Out-of-network |
|---|---|---|
| Google Ads, per admission | $2,000 to $5,000 | $7,000 to $15,000 |
| Directories, per admission | $2,000 to $5,000 | $7,000 to $15,000 |
| SEO, per admission | A few hundred dollars up to $2,000 to $5,000 | |
| Cost per VOB, all channels | A couple hundred dollars up to $2,000 (top end in some out-of-network cases) | |
Read this first: these ranges are mostly for detox and residential. PHP and IOP can cost less per admission, but they vary widely by region and insurance type. The figures come from our own campaign work, not from a published study.
The rest of this guide explains why the range runs so wide, checks it against public data and our own math, and shows how to track your own number.
Why is the range so wide?
Four inputs move cost per admission more than anything your agency does.
- Network status. An out-of-network center needs callers with out-of-network benefits that cover treatment. Few callers have them. One call seller reports that only about 3% of its calls verify out-of-network benefits. AAC said the same thing in its SEC filings: in-network beds "generally have a lower advertising and marketing expense on a per admission basis than out-of-network residential beds" (AAC 2017 10-K).
- Level of care. Detox searches cost the most. Our Keyword Planner pull shows $95.56 per click for "detox near me" against $52.95 for "iop near me." In our experience, detox and residential admissions bring in more revenue, so centers bid harder for them.
- Region. Competition varies by metro. The Verge reported in 2017 that one rehab click cost about $221 in Arizona and $43 in New York, per SEMrush estimates. The numbers are old, but the spread still holds in our experience.
- Payer. In our experience, a PPO caller, an HMO caller and a Medicaid caller lead to very different VOB outcomes. Your payer contracts decide which callers you can admit, and that decides how many calls you pay for per admission.
How public data and our math line up
Our ranges come from running campaigns. Here is how they compare with the few public numbers that exist and with a bottom-up calculation.
Webserv 2025: one agency's disclosed results
Webserv's 2025 report pools paid search results across its active clients. It spent $16.5M and produced 6,467 VOBs at $2,552 per VOB and 994 admits at $16,608 per admit. Our math: 994 admits from 6,467 VOBs is about a 15% VOB to admit rate.
Treat this as one data point. An agency published it about its own clients, no third party audited it, and it blends in-network and out-of-network centers. Its cost per admit sits just above the top of our out-of-network range.
AAC's SEC filings: an older floor
American Addiction Centers reported both ad spend and admissions while it was public. Our math from its filings: the ad line divided by admissions comes to about $3,300 per admission in 2014 and about $760 in 2018, using admissions from the fiscal 2015 10-K and the March 2019 earnings release.
Treat that as a floor. The ad line leaves out AAC's call center staff, and AAC owned Rehabs.com and Recovery.org, so it generated much of its own demand. A single center buying traffic will not see these numbers.
Our math: from cost per click to cost per admission
Cost per admission = CPC ÷ click to inquiry rate ÷ inquiry to VOB rate ÷ VOB to admit rate. An inquiry is a call or form fill.
The inputs, and where each one comes from:
- CPC: $45 ("rehab centers near me") and $57 ("inpatient rehab"), from our Google Keyword Planner pull on October 4, 2026. SEMrush shows lower estimates on the same terms.
- Click to inquiry, 8%: LocaliQ reports an 8.09% average conversion rate for healthcare search ads. Assumption: rehab performs like healthcare overall.
- Inquiry to VOB, 40% in-network and 25% out-of-network: Webtonic, an agency, cites 25% to 40% for healthy accounts. Assumption: in-network sits at the top, out-of-network at the bottom.
- VOB to admit, 36% in-network: Webserv's measured viable VOB to admit rate is 35.9%. Assumption: most in-network VOBs come back viable.
- VOB to admit, 15% to 25% out-of-network: 15% is Webserv's blended rate. 25% is the low end of the 25% to 45% that Navix Health gives for strong intake teams.
| Scenario | Cost per inquiry | Cost per VOB | Cost per admission |
|---|---|---|---|
| In-network: $45 CPC, 8%, 40%, 36% | $563 | $1,406 | $3,906 |
| Out-of-network: $57 CPC, 8%, 25%, 25% | $713 | $2,850 | $11,400 |
| Out-of-network at Webserv's 15% VOB to admit | $713 | $2,850 | $19,000 |
What the math shows. The in-network result of $3,906 lands inside our $2,000 to $5,000 range. The out-of-network result of $11,400 lands inside our $7,000 to $15,000 range when intake converts 25% of VOBs. At Webserv's blended 15%, it climbs to $19,000, above our range and close to Webserv's own $16,608.
The out-of-network VOB cost of $2,850 runs above the $2,000 top of the VOB range we see. Webserv's $2,552 sits there too. Our read: paid search out-of-network VOBs often cost more than $2,000 unless the click to inquiry rate beats the healthcare average. That is the lever to work on.
The channels, briefly
Google Ads
Google restricts addiction treatment ads. In the US you need LegitScript certification plus Google's own certification. LegitScript charges a $1,395 to $1,595 application fee and a $2,550 to $3,095 annual fee per facility. Our math: a single facility pays $4,690 in year one before any ad spend. Clicks run $45 to $96 on commercial terms in our Keyword Planner pull.
Directories and raw calls
Directories and call publishers mostly sell raw calls. In our experience a raw call costs $15 to $100, and Alcoholics Anonymous meeting calls go as low as $15. Intent runs very low. Many callers want a meeting, a job or general information. A cheap call is not a cheap VOB, so track every bought call through to VOB and admission.
SEO
SEO gives the lowest cost per admission over time, from a few hundred dollars up to $2,000 to $5,000 in our experience. You pay for content and technical work, not per click. It takes months to build, so most centers run paid search while organic traffic grows.
The legal line, in plain English
EKRA makes it a federal crime to pay anyone to induce a referral to a treatment program. Its exception for employees and contractors only protects pay that doesn't vary with the number of referrals, so per-admit vendor fees and per-admit staff bonuses get no protection from it. Flat fees set in advance, which do not change with how many patients arrive, are the standard safe structure. Florida, California and New Jersey add their own laws. Per-call pricing is a gray zone with no ruling we could find (our read), and paying only for insured or verified callers adds risk. NAATP's ethics code bars members from buying or selling leads, phone calls included, so talk to healthcare counsel before you sign.
How do you track your own cost per admission?
Measuring is not the same as paying. You can and should track your own cost per admission. The legal line falls on how you pay vendors, not on what you measure.
- Total your spend by channel each month: ad spend, directory fees, bought calls and SEO retainers.
- Tag every inquiry by source with call tracking and form tracking.
- Log each VOB with its source, payer and network status.
- Log each admission with its source and level of care.
- Divide spend by admissions for each channel, split by in-network and out-of-network, and by detox, residential, PHP and IOP.
Then compare your numbers to the table at the top. If one channel sits well above our range, check the weakest step in its chain. That is usually call answer speed or the inquiry to VOB rate.

How much does a rehab admission cost to acquire?
Running campaigns for treatment centers, we see a detox or residential admission from Google Ads or directories cost $2,000 to $5,000 in-network and $7,000 to $15,000 out-of-network. SEO runs from a few hundred dollars up to $2,000 to $5,000 per admission. PHP and IOP can cost less, but they vary widely by region and insurance type.
How much does a rehab VOB cost?
In our campaigns, a VOB (verification of benefits) costs from a couple hundred dollars up to $2,000 in some out-of-network cases. Webserv, an agency, reports $2,552 per VOB across its 2025 paid search clients.
Why does an out-of-network admission cost more to acquire?
Fewer callers have out-of-network benefits that cover treatment, so you pay for more calls to find each one. One call seller reports that about 3% of its calls verify out-of-network benefits. AAC's SEC filings also state that in-network beds cost less to market per admission.
Is SEO cheaper than Google Ads for rehab admissions?
Over time, yes. In our experience SEO delivers the lowest cost per admission, from a few hundred dollars up to $2,000 to $5,000. It takes months to build, so most centers run paid search while SEO matures.
Are directory and pay-per-call calls cheaper?
Per call, yes. Per VOB, often not. In our experience raw calls cost $15 to $100, and AA meeting calls go as low as $15, but intent runs very low. Judge every bought call by how many become VOBs and admissions.
Can I pay a marketing vendor per admission?
We advise against it. EKRA makes it a federal crime to pay anyone to induce a referral to treatment, and its exception for employees and contractors only protects pay that doesn't vary with the number of referrals, so per-admit fees get no protection from it. Flat fees set in advance are the standard safe structure. You can still track your own internal cost per admission. Talk to healthcare counsel before you sign any vendor contract.
