Key takeaways
- Zellig evaluates adults and teens ages 12 and up for ADHD across Pennsylvania, by secure video and in-person, with intakes usually available within the week.
- The evaluation takes two visits: a 60-90 minute psychiatric history, standardized questionnaires from you and someone who knows you well, then a follow-up to review results and options together.
- Most major commercial insurance plans cover it as standard visits. There is no separate testing fee.
If local ADHD testing has meant long waitlists or expensive flat-fee packages, there’s another option: a thorough, two-visit ADHD evaluation in person or by secure video. Most commercial insurance covers it, and most patients start within the week. No referral needed. At Zellig Psychiatry, we evaluate adults and teens ages 12 and up; teens go through the same process with a parent contributing to the questionnaire step, and our ADHD care for teens page covers what comes after.
Plenty of the people sitting in our virtual waiting room assumed for years that they were too old for this diagnosis. The numbers say otherwise. An estimated 15.5 million U.S. adults (6.0%) had a current ADHD diagnosis in 2023, and more than half of them were diagnosed in adulthood, according to a CDC report on ADHD in adults published in October 2024. Most ADHD evaluations happen by telehealth now, for a practical reason: any clinician licensed in Pennsylvania can evaluate you from anywhere in the state. That holds even in a town with no psychiatric practice at all. Distance stopped being an obstacle.
What an ADHD evaluation at Zellig involves
An ADHD evaluation at Zellig is personalized to the person in front of us. Many evaluations take about two visits, but the process may look different depending on what you need. Between visits, you may be asked to answer additional questions, and we usually gather collateral information from people who know you well. At the follow-up, your clinician reviews the full picture with you. From there, we discuss what the information suggests and what the best path forward may be.
Why this much structure? Because there is no single test for ADHD, and the CDC notes that sleep disorders, anxiety, depression, and certain learning disabilities can produce nearly identical symptoms. A ten-minute screener cannot separate those. A careful history often can. In our experience, the detail that settles a diagnosis is often something the patient never thought to mention, like a parent recalling third-grade report cards that all say the same thing.
The diagnostic standard itself demands this depth. The DSM-5-TR, the manual U.S. clinicians use to diagnose ADHD, requires five or more symptoms of inattention or hyperactivity-impulsivity for ages 17 and up (six or more for children 16 and under), with several symptoms present before age 12, showing up in two or more settings, and clearly interfering with daily functioning. You can’t confirm “before age 12” and “two or more settings” from one person’s memory in one sitting. That is exactly what the second questionnaire is for.
If you want the full picture of how adult ADHD is diagnosed, the complete DSM-5-TR criteria and exactly who can evaluate you, our diagnosis guide walks through it. Here, the focus is the evaluation you can book.
Here is the full sequence:
- Visit one: comprehensive psychiatric history (60-90 minutes). We cover current symptoms, childhood patterns, school and work history, sleep, mood, anxiety, substance use, medical history, and family history. Much of the work of ruling out other causes happens here.
- Between visits: questionnaires and collateral forms. You complete standardized symptom questionnaires. Someone who knows you well completes a collateral version. Collateral information means input from a person who knew you growing up or knows you now, such as a parent or a longtime partner. For teens, a parent’s input is built into the process, which matches the American Academy of Pediatrics’ recommendation to gather reports from adults who see the child in different settings.
- Visit two: discussion and a path forward. Your clinician walks through what the history and questionnaires show, including whether the findings are consistent with ADHD or point to something else. From there, we discuss a plan to help you function better and feel better, whether or not ADHD is the final diagnosis.
About 7 million U.S. children ages 3-17 (11.4%) have ever been diagnosed with ADHD, per CDC data on ADHD in children from 2022, so the teen path is a routine part of our week. So is the adult path with no childhood paper trail, which is exactly the gap collateral input fills.
If you’re not sure a full evaluation is the right next step, this comparison may save you one:
| Option | What it is | When it fits |
|---|---|---|
| Screening questionnaire | A short self-scored symptom checklist, free online | A first gut-check before you book anything |
| Full clinical evaluation (what we do) | Two visits plus rating scales and collateral input, confirming or ruling out ADHD against DSM-5-TR criteria | You want an answer you can act on, billed through insurance |
| Neuropsychological testing | Several hours of cognitive testing with a psychologist | Learning, memory, or other cognitive questions need mapping alongside ADHD |
How much does ADHD testing cost?
ADHD testing at Zellig is billed as standard psychiatric visits and covered by most major commercial insurance plans in Pennsylvania. There is no separate testing fee. You pay your plan’s usual copay or deductible for the intake and the follow-up visit, and we verify your benefits before your first appointment so the cost is known up front.
In practice, your ADHD test cost comes down to your plan’s outpatient mental health benefit. We’re in network with Aetna, Cigna, Independence Blue Cross, Highmark Blue Cross Blue Shield, Capital BlueCross, UnitedHealthcare, Geisinger, UPMC, and several others listed on our payment options page. We cannot accept Medicare, Medicaid, or other government-funded plans at this time. Self-pay rates, which are visible on our payment page, are available if you’d rather not use insurance.
One caution as you compare prices: a flat-fee “ADHD testing package” at another practice often means a neuropsychological battery. ADHD is diagnosed through a clinical evaluation, and no specific test is required, so paying more does not buy a more official answer.
ADHD testing in the Main Line, Bucks County, and across Pennsylvania
Every Zellig clinician is licensed to practice across Pennsylvania, and the entire evaluation is compatible with telepsychiatry, meaning live, private video visits. ADHD testing in Pennsylvania therefore doesn’t depend on what’s within driving distance. Philadelphia, Pittsburgh, Erie, Scranton, Allentown, State College: same process, same timeline.
If you’re near the Main Line and want an in-person option, we have one. Our Wayne office at Building 485, The Meadows Office Complex, 485 Devon Park Drive, Wayne, PA 19087 sees patients in person with Riley Guinan, PA-C on the third Monday of each month, 3 to 9 PM. In Bucks County, our Perkasie location at 1259 Route 113, Perkasie, PA 18944 is available by appointment. All other visits, statewide, happen by video.
From Pittsburgh, Erie, or anywhere in western and central Pennsylvania, the full evaluation runs by video with the same clinicians on the same schedule. Telehealth has quietly become a standard route to ADHD care nationally; the CDC found nearly half of adults with ADHD have used it for their condition.
Do you need neuropsychological testing?
Most people do not need neuropsychological testing, a multi-hour battery of cognitive tests given by a psychologist, to get an ADHD answer; ADHD is diagnosed through a clinical evaluation, with no single test required. It matters when learning disabilities or memory concerns need mapping alongside ADHD. If that’s your situation, we’ll say so and refer you.
After the diagnosis: treatment at Zellig
The follow-up visit doubles as your treatment planning session, so there’s no third appointment standing between you and a path forward. At Zellig, we provide comprehensive ADHD treatment. If ADHD is confirmed, your clinician lays out the options and their reasoning. We typically don’t start with stimulants. Plans usually begin with non-stimulant medication, therapy, or both, with stimulants considered when first-line steps don’t do enough. That order reflects how we practice: medication decisions are made deliberately, with you.
If it turns out not to be ADHD, you still leave with an answer and a plan. The history usually shows what else is driving the symptoms, most often anxiety or depression, sometimes disrupted sleep, and we treat all of those too. Either way, follow-ups start at 30 minutes, which leaves room to actually adjust the plan.
