Most therapists wait 15 minutes past the scheduled start time before marking a client as a no-show. This is the most widely used threshold in private practice and on telehealth platforms, and it strikes a balance between giving clients a reasonable window to arrive and protecting the therapist’s schedule. What you do during those 15 minutes, and how you handle the situation afterward, matters just as much as the wait itself.
The 15-Minute Standard
While no single licensing board mandates an exact number of minutes, 15 minutes has become the default grace period across most practice settings. Telehealth platforms like Rula formalize this into a structured outreach sequence: resend the session link at 3 minutes, call the client at 5 minutes, and mark the appointment as a no-show at 15 minutes if the client still hasn’t appeared. Even therapists in traditional office settings tend to follow a similar rhythm, checking their phone or sending a quick text a few minutes in and closing the window around the 15-minute mark.
Some therapists use a shorter 10-minute window, particularly if they have back-to-back appointments. Others allow the full session length to pass before officially recording a no-show. The key is picking a policy, communicating it clearly in your informed consent documents, and applying it consistently.
What to Do During the Wait
Those 15 minutes shouldn’t be passive. A brief, structured outreach effort accomplishes two things: it gives the client a genuine chance to show up, and it creates documentation showing you made a good-faith attempt to connect. A reasonable sequence looks like this:
- 3 minutes after the start time: Send a text or email reminder with the session link or office location.
- 5 minutes: Call the client directly.
- 15 minutes: If there’s still no response, record the session as a no-show and document your outreach attempts in the client’s chart.
For telehealth sessions, technical difficulties complicate things. A client may be struggling with a broken link or a software update rather than choosing not to attend. Having a backup plan, like switching to a phone call if video fails, can save sessions that would otherwise be lost to a glitch rather than a true no-show.
Why Chronic Lateness Hurts Treatment
Waiting for a late client isn’t just a scheduling inconvenience. Research from the American Psychological Association found that no-shows have measurable negative effects on treatment outcomes, particularly when they happen early in therapy. Clients who missed sessions before their third appointment showed noticeably slower symptom improvement compared to consistent attenders, likely because those early sessions are critical for building trust and engagement between therapist and client.
Once a strong therapeutic relationship is established (generally after the first few sessions), the occasional missed appointment has a much smaller impact. But repeated no-shows at any stage disrupt the flow of treatment. Therapists end up spending valuable session time catching up, re-explaining concepts, or addressing the attendance problem itself rather than doing the clinical work. Over time, a therapist who keeps getting stood up may also find it harder to bring the same patience and energy to that client’s sessions.
This is worth considering when you’re deciding how flexible to be. Extending the grace period repeatedly or letting chronic lateness slide can feel compassionate, but it may actually undermine the treatment you’re trying to provide.
Setting a Clear Late Policy
The best way to handle late arrivals is to address them before they happen. Your informed consent or practice policies should spell out three things: how long you’ll wait, whether late arrivals will receive a shortened session or be rescheduled entirely, and what fees apply for no-shows or late cancellations.
Most practices define a late cancellation as anything with less than 24 hours’ notice, and many treat arriving more than 15 minutes late as equivalent to a late cancellation for billing purposes. If you charge a fee for no-shows, make sure this is documented in the financial agreement the client signed at intake.
One important exception: if you see clients through Medicaid, you generally cannot bill for missed appointments. Federal policy treats missed appointments as a cost of doing business rather than a billable service. Private-pay and commercial insurance clients can be charged a no-show fee, but only if the policy was disclosed in advance.
Avoiding Abandonment Concerns
Some therapists worry that enforcing a strict late policy could cross into ethical territory, specifically the prohibition against abandoning clients who still need care. The ethical standard from the National Association of Social Workers is clear: you should take reasonable steps to avoid abandoning clients, but enforcing a financial or attendance policy is not abandonment as long as the terms were communicated upfront and the client doesn’t pose an imminent safety risk.
If a client repeatedly no-shows and you’re considering ending treatment, the ethical path involves discussing the pattern directly with the client, exploring what’s driving the absences, and offering referrals if the therapeutic relationship isn’t working. Terminating services over unpaid no-show fees is also permissible, provided the financial terms were clear from the start and you’ve discussed the consequences with the client before acting on them.
When Lateness Is Clinical Material
Not every late arrival is a logistical problem. For some clients, showing up late is itself a meaningful pattern worth exploring in session. Anxiety about therapy, ambivalence about change, difficulty with boundaries, or avoidance of painful topics can all manifest as chronic lateness. Before defaulting to enforcement, it’s worth asking whether the behavior is telling you something about the client’s experience of treatment.
That said, exploring lateness as clinical material and holding firm boundaries around it aren’t mutually exclusive. You can have a curious, nonjudgmental conversation about what’s making it hard to arrive on time while also being transparent that the session will still end at its scheduled time and that your no-show policy still applies. Consistent structure often creates more safety for clients than flexibility does, particularly for those who struggle with boundaries in other areas of their lives.
