Drug testing policy for treatment programs: how to write one for an IOP or PHP

The short answer

A treatment program's drug testing policy should say: why you test (as a clinical tool, not punishment); how often at each level of care, on random days plus tests for cause; how specimens are collected, with unobserved collection as the default; which instant tests you use under your CLIA certificate of waiver and when a lab confirms a result; who orders tests and how each order's medical necessity is written in the chart; how results are recorded and protected under 42 CFR Part 2; and how staff respond to a positive, including that prescribed medications such as buprenorphine are expected and that a positive result alone is never a reason for discharge.

Purpose and principles

The policy in our program kit opens with one sentence of purpose: to use drug and alcohol testing as a tool for safety and recovery, collected with dignity, read accurately, and answered with help rather than punishment. Four principles follow, and every other section has to agree with them:

• Every test has a reason the record can explain. Frequency is set by the treatment plan; consent is obtained at admission.
• A result is one piece of information. Staff talk with the client before drawing conclusions.
• Prescribed medications are expected, including medications for opioid use disorder, and are never treated as a violation.
• Only tests that change care are ordered. Large panels by default, or tests that don't change care, are a billing risk and aren't allowed.

We didn't find a rule in Texas's chemical dependency treatment facility chapter (26 TAC 564) that sets how often an outpatient program must test, so frequency is a clinical decision you document, checked against each payer's policy and your accreditor's expectations. Check the current rule text; our 26 TAC 564 guide covers what the chapter does require.

How often to test

The frequency table from our template. These are typical starting points, not a standard; write your own and tie each client's frequency to their plan.

Level or situation	Typical frequency (set yours)	Why
PHP (ASAM 2.5)	At least weekly, on random days	Most acute clients, most days in program
IOP (ASAM 2.1)	Weekly to every other week, on random days	Monitors progress without over-testing
Outpatient (ASAM 1)	As the plan sets, at least monthly while in care	Stable clients; testing tapers with progress
For cause	When use is suspected, after a reported lapse, or before a level-of-care decision	The result can change the plan or level today

Random means random. If clients know testing is every Monday, the test tells you less. Pick days with a simple random method and record it. And write the reason for a for-cause test in the note at the time, not afterward.

Collection and specimen validity

• Unobserved collection is the default. Check the temperature strip and look for signs of tampering on every specimen.
• Observed collection only with a documented reason (a tampered or out-of-range specimen, or the client's own request), by a trained staff member of the same gender identity as the client, with as much privacy as safety allows.
• Secure the collection bathroom: no running water or soap within reach during collection, and a bluing agent in the toilet where possible.
• Saliva or breath tests are acceptable alternatives when they fit the purpose.
• Chain of custody for lab specimens: label in front of the client, seal, have the client initial the seal, sign and time every hand-off on the custody form, and store as the lab instructs until pickup. A break in the chain is noted on the form and in the record.
• Staff: in our job descriptions, behavioral health technicians collect specimens and run point-of-care tests only after documented competency, and wear gloves when handling urine or saliva.

Instant tests and lab confirmation

Most programs read instant urine cups or dip cards on site and send some specimens to a reference lab. Two rules keep this clean:

1. The instant test is presumptive. Use only devices the FDA lists as waived (search the FDA CLIA database), under a CLIA Certificate of Waiver for your site, following the package insert exactly. How to get the certificate is in our CLIA waiver guide.
2. Confirm when it matters. Send a presumptive positive to a lab for confirmation (for example, by mass spectrometry) when the result will change care, when the client disputes it, or when a prescribed medication might explain it. A decision with major consequences waits for the confirmation or for the client's honest account.

Situation	Send for confirmation?
Client says "yes, I used Saturday" and the cup agrees	Usually not; the conversation is the information. Document both.
Client denies use and the cup is positive	Yes, before any decision rests on it
Positive for a class the client is prescribed (benzodiazepine, opioid, stimulant)	Yes, if you need to know which drug; check the prescription and the PMP-reconciled medication list first
Client on buprenorphine with a negative buprenorphine result	Talk with the client and the prescriber; a lab test can tell you more if it changes care
Result will decide a level-of-care change or a report the client consented to (court, employer)	Yes

Choose the lab carefully and keep the relationship clean; see lab relationships and EKRA before you sign anything with one.

Orders and medical necessity

Drug testing is one of the services payers audit most closely, and the questions are always the same: who ordered this test, why, and how did the result change care? Build the answers into the workflow:

• An order for each client, from a licensed practitioner allowed to order it, based on that client's history and plan. Avoid blanket standing orders that test every client the same way regardless of need; they're hard to defend as medically necessary.
• The reason in the chart: the plan's testing frequency and its reason, or the specific cause for an unscheduled test.
• Match the panel to the client: the substances they use or might plausibly use, plus the medications you need to confirm they're taking. Not the biggest panel the lab offers.
• Use the result: the note after each result says what it meant and what, if anything, changed. A result nobody discussed is a test that didn't need to be billed.
• Review patterns quarterly: the clinical director looks at testing volume per client, confirmation rates and any client tested far more than the policy says.

Our IOP / PHP Program Launch writes this policy along with the admission and continued-stay criteria based on The ASAM Criteria, so testing shows up in the same place as the rest of the medical-necessity record. For an open program, our chart audit reads charts the way a payer auditor would, including tests billed against orders and notes.

Billing codes

Who bills depends on who performs the test: your program bills the instant tests it reads under its own CLIA certificate (if the payer pays for them separately); the reference lab bills the confirmations it performs. Don't bill for a test someone else performed.

Code	What it is	Notes
80305	Presumptive drug class test read by direct optical observation (cups, dip cards)	Medicare requires the QW modifier for waived tests (CMS MM13253)
80306, 80307	Presumptive tests read with instrument-assisted direct optical observation (80306) or by instrument chemistry analyzers such as immunoassay (80307)	Usually lab or analyzer testing beyond a waived cup
G0480 to G0483	Definitive (confirmation) drug testing, priced by the number of drug classes	HCPCS codes Medicare and many plans use; billed by the lab that performs it

• Per diem programs: many contracts treat on-site cups as part of the IOP or PHP daily rate (for example H0015 or S0201), so a separate 80305 line would be denied or would be a billing error. Read each contract. Our IOP and PHP billing codes guide and per diem billing guide explain what the daily rate covers.
• CLIA number on the claim (box 23 on the CMS-1500), and for Texas Medicaid, the CLIA certificate must be in your PEMS enrollment or lab codes deny for dates of service from June 1, 2026.
• Frequency limits: payers' drug testing policies can cap how many presumptive and definitive tests they'll pay for in a period and require documentation of why definitive testing was needed. Pull each plan's current policy into your billing settings.

After a positive result

1. Safety first: overdose risk, intoxication, a ride home if impaired. Call 911 for any medical emergency.
2. Talk: the counselor talks with the client the same day or at the next session, with curiosity rather than blame.
3. Review the plan: what led to use, what helps, and whether the level of care still fits. Update the plan and note it.
4. Offer naloxone and overdose education, especially after a period of not using.
5. Never discharge for a positive result alone. A pattern that shows the client needs more care leads to a higher level or a referral. That's the continued-stay argument too: see ASAM continued-stay documentation.

Prescribed medications and MOUD

Clients taking buprenorphine, methadone or naltrexone, or a prescribed benzodiazepine or stimulant, will test positive for what they're prescribed. The policy says those results are expected and never a violation, and the U.S. Department of Justice's guidance explains that the ADA protects people taking prescribed medication for opioid use disorder (ADA.gov). Reconcile each client's medication list at admission so staff reading a cup know what to expect, and coordinate with the prescriber, with consent, when results suggest a problem. Our guide to adding MAT to an IOP covers the rest of the MOUD policy.

Records and 42 CFR Part 2

• Record the date, kind of test, what was tested for, the result, who collected it, whether it was observed, any confirmation and its result, and the conversation with the client.
• Results are part of the SUD treatment record protected by 42 CFR Part 2 and HIPAA. They're shared outside the program only with a written consent that meets Part 2, or as Part 2 allows, and may not be used in civil, criminal or administrative proceedings against the client except as Part 2 permits.
• Courts, probation, employers: report results only under a signed Part 2 consent that names the recipient and what's shared. Our 42 CFR Part 2 guide has the consent elements.

Questions

How often should an IOP drug test clients?

There isn't one required number in Texas rules that we found. A common starting point is weekly to every other week on random days for IOP, at least weekly for PHP, plus tests for cause, with each client's frequency set in the treatment plan and checked against each payer's policy.

Can a treatment program require observed urine collection?

It can, but make unobserved collection the default and observe only with a documented reason, such as a tampered or out-of-range specimen, using a trained staff member of the same gender identity, with as much privacy as safety allows.

Can we discharge a client for a positive drug test?

A positive result alone shouldn't end treatment: return to use is a symptom of the condition you treat. Review the plan, and if the pattern shows the client needs more care, move them to a higher level or refer them.

Do we need a doctor's order to drug test?

Payers expect a test to be ordered by a practitioner allowed to order it and to be medically necessary for that client, documented in the chart. Individualized orders are easier to defend than blanket standing orders.

Can our IOP bill 80305 on top of the per diem?

Often not: many contracts include on-site testing in the IOP or PHP daily rate. Read each contract and the plan's drug testing policy before billing it separately.

Who can see a client's drug test results?

Program staff who need them for treatment. Outside the program, results go only to someone named in a Part 2 compliant written consent, or as 42 CFR Part 2 otherwise allows.
