Key Takeaways
The message lands and sets the tone.
ADHDcentraal sends an automatic confirmation when someone contacts its administration. The reply makes one early promise: the email has been received and a full response should follow within five working days. It turns silence into a timeline. It shows there is a queue, not a void.
Money stress is separated from medical stress.
The reply tells people that if the question is financial — asking for a new invoice, requesting extra time to pay, or setting up a payment plan — they do not have to sit and wait. They can go straight to Infomedics, the external Dutch billing company that issues invoices on behalf of healthcare providers and arranges things like payment postponement or instalment plans for those invoices. Infomedics can be reached online or by phone at 036 20 31 900 (weekdays 09:00–17:00 local time / Europe/Amsterdam).
Costs and reimbursement are explained up front.
The clinic directs people to its own pages about costs, reimbursements and health insurers. Those pages break down which parts of ADHD assessment and treatment tend to be insured, which parts fall to the patient, and how the Dutch deductible and medication co-payment work.
There are human contact routes — and their hours are not hidden.
The email includes an administrative email address for reimbursement and billing questions (vergoedingen@adhdcentraal.nl) and gives a central phone number for ADHDcentraal (088 3131 231). The reply states that the line is staffed on Monday, Tuesday and Thursday from 09:00 to 12:00 local time (Europe/Amsterdam). On ADHDcentraal’s own billing guidance, a similar number is also described as reachable on Monday and Wednesday from 13:00 to 15:00 local time (Europe/Amsterdam), specifically for financial administration. Both windows are published as office hours for real humans, not a callbot.
The brand makes its position explicit.
ADHDcentraal describes itself publicly as a Dutch knowledge and treatment center for adults with attention-deficit/hyperactivity disorder. Its promise is structure: focused diagnostics, same-day clarity around assessment, and ongoing guidance after the label. The brand voice leans on “from chaos to focus,” and the billing workflow with Infomedics fits that same design — controlled, predictable, navigable.
Story & Details
The first contact: “We got your message.”
The automated reply from ADHDcentraal opens with reassurance. In Dutch it says, “Wij proberen je mail binnen 5 werkdagen op te pakken” (translated from Dutch: “We aim to pick up your email within five working days”). That line matters because it frames expectation. The sender is told that follow-up is coming, and roughly when.
The reply then moves quickly into self-service paths. It explains that if someone wants a new invoice, wants to request payment postponement, or wants to arrange a payment plan, this can be handled directly. The message points straight to Infomedics, including both a website reference and the phone number 036 20 31 900 for questions about invoices, payment extensions or instalments (weekdays 09:00–17:00 local time / Europe/Amsterdam). This creates a fast lane for money issues instead of forcing those questions to sit in a clinical inbox.
That separation is intentional. Clinical questions wait in the five-day pipeline. Financial pressure gets a same-day outlet.
Money questions don’t have to wait
Infomedics is a Dutch medical billing partner. Care providers — including mental health and ADHD services — send billing data to Infomedics, and Infomedics sends the invoice to the patient. The company also checks with the health insurer and shows what part of the bill is already reimbursed. If the full amount can’t be paid at once, Infomedics allows payment postponement (pushing the due date) or a payment plan (paying in instalments over time). This can be requested directly through Infomedics’ portal or by phone.
That approach turns “I can’t pay this right now” into a standard workflow instead of a moral crisis. It’s calm. It’s procedural. It treats late payment like logistics, not failure.
Understanding costs, reimbursement and insurers
The automated reply includes links to ADHDcentraal’s own information pages on costs, reimbursements and health insurers. Those pages explain how adult ADHD assessment and treatment are billed, and they highlight a recurring reality of Dutch care: even when mental healthcare is covered by insurance, there may still be personal financial exposure. The annual deductible in the Netherlands can be used up quickly. Certain medication can require a statutory personal contribution. Some insurer contracts are in place and some are not, which shifts who pays what.
The clinic’s messaging is essentially: know what will likely be reimbursed, know what may come out of pocket, and recognise that seeing an invoice from Infomedics can be normal. ADHDcentraal also instructs patients to send their insurer’s reimbursement overview to the clinic so that the clinic can calculate what still needs to be paid.
This tone mirrors current reporting around adult ADHD more broadly. Mainstream coverage describes attention-deficit/hyperactivity disorder as a neurodevelopmental condition — not a personality quirk — that persists into adulthood and can affect work, organisation, relationships and mood. Reputable journalism stresses that a proper diagnosis should come from structured clinical assessment, not just a viral checklist. That same reporting notes that medication is often part of treatment, but rarely the whole story; behavioural strategies, predictable routines and coaching tend to sit alongside medication in real life.
Reaching an actual person
The reply from ADHDcentraal does not just point to web pages. It gives live contact routes.
It lists a shared email address for reimbursement and billing questions: vergoedingen@adhdcentraal.nl. It lists a phone number for ADHDcentraal’s administrative desk: 088 3131 231. In the email response, that line is described as reachable Monday, Tuesday and Thursday between 09:00 and 12:00 local time (Europe/Amsterdam). On ADHDcentraal’s own billing and Infomedics guidance, a similar contact line for the financial administration is described as reachable Monday and Wednesday between 13:00 and 15:00 local time (Europe/Amsterdam). Both windows appear in official patient-facing material.
That kind of clarity matters. It shows that the back office is real, that there are humans assigned to billing questions, and that callers are not being pushed into an endless switchboard. It also hands the sender a sense of agency: if nothing comes back within five working days, there is a named mailbox and a reachable phone window.
The reply also references a postal channel — ADHDcentraal’s mailbox address (Postbus 6095, 3503 PB Utrecht, Netherlands) — which underscores that this is an established Dutch healthcare entity with physical presence, not a faceless portal.
How ADHDcentraal frames itself in the ADHD landscape
ADHDcentraal publicly presents itself as a knowledge and treatment center for ADHD in adults. Its site speaks in direct language: “Van chaos naar focus” (“From chaos to focus,” translated from Dutch). That slogan reflects a particular promise: structured diagnostics, clear naming of the condition, and then guided follow-up rather than leaving people to fend for themselves in the aftershock of diagnosis.
The clinic’s published model emphasises a diagnostic day with in-depth psychiatric interviewing, validated testing and objective measures like the QbTest. It then offers continuing treatment, often medication combined with tailored guidance. The brand narrative leans heavily on clarity: if attention keeps slipping, if impulsivity keeps blowing up plans, if internal restlessness has been running the show for years, the clinic’s message is that this can be described, measured and addressed.
That message lines up with current public reporting and expert commentary. Coverage from established outlets describes ADHD as highly heritable, rooted in neurodevelopment, and absolutely present in adults — not just in hyperactive schoolchildren. The same coverage warns that social platforms can blur the line between ordinary distraction and clinically significant impairment. It also notes a tension that millions of adults report: the sense that diagnosis can feel like someone finally turned the lights on, and yet navigating access to assessment, medication and reimbursement still demands energy that ADHD already drains.
Underneath all of this sits a shared idea: care is both clinical and administrative. The label matters. The follow-up matters. And the invoice, unfortunately, also matters.
Conclusions
ADHDcentraal’s automatic reply is more than a courtesy note. It sets expectations by saying a response should arrive within five working days. It separates urgent financial stress from the slower clinical process by pointing directly to Infomedics for invoice copies, payment postponement and instalment plans. It links out to clear explanations of costs, reimbursements and insurer agreements. And it tells people exactly how to reach the administrative desk — including an email address, a phone number, and published office windows in local time (Europe/Amsterdam). The effect is that the person who wrote in is not left to wonder “what now?” There is a map.
Placed in the wider discussion around adult attention-deficit/hyperactivity disorder, that map carries weight. Adult ADHD is widely recognised as a neurodevelopmental condition that can shape work, focus, organisation and emotional load well past school age. Serious outlets now talk about assessment and follow-up as necessities, not luxuries. ADHDcentraal leans into that framing: structured diagnostics, practical aftercare, and a billing path that treats money trouble as solvable logistics rather than moral failure. It feels like triage for both the mind and the invoice.

Appendix
invoice
In this context, “invoice” refers to the bill for ADHD assessment or treatment. ADHDcentraal often has Infomedics send that bill on its behalf. Infomedics can resend the invoice if it was lost or never received.
payment postponement
“Payment postponement” is the option to push back the due date on a medical invoice. Infomedics allows patients to request extra time when payment by the original deadline would cause financial strain.
payment plan
A “payment plan” is an instalment arrangement. Instead of paying the full invoice at once, the total is split into smaller scheduled payments agreed with Infomedics. This is framed as standard, not shameful.
reimbursement
“Reimbursement” is the portion of assessment or treatment costs that the health insurer covers. ADHDcentraal asks patients to forward the insurer’s reimbursement overview so the remaining out-of-pocket amount can be calculated and explained.
health insurer
The health insurer is the Dutch insurance company responsible for covering medically necessary care under the policy. Coverage depends on whether ADHDcentraal has a contract with that insurer, and on the patient’s deductible and co-payment obligations.
administrative contact window
ADHDcentraal’s communication includes explicit “reachable” windows for its administrative and financial desks. One source states that the main admin phone line at 088 3131 231 is available Monday, Tuesday and Thursday from 09:00 to 12:00 local time (Europe/Amsterdam). Another published guidance for the financial administration lists Monday and Wednesday from 13:00 to 15:00 local time (Europe/Amsterdam). Both are presented as staffed windows, not automated bots.
Infomedics
Infomedics is a Dutch healthcare billing company that sends invoices for care providers, checks with insurers what is reimbursed, and then bills the patient for the remaining amount. It offers practical tools: request a copy of the invoice, ask for payment postponement, or arrange a payment plan. It can be contacted directly by patients at 036 20 31 900 (weekdays 09:00–17:00 local time / Europe/Amsterdam) without going through the clinic first.
adult ADHD
Adult attention-deficit/hyperactivity disorder is described in specialist clinics and in major outlets as a neurodevelopmental condition that can persist into adult life and shape work, emotional regulation, planning, focus and impulse control. The modern view treats ADHD as real, often heritable, and responsive to structured assessment and guided follow-up — not just as a childhood phase or a social media label.
