MijnMCL is the patient portal for Medisch Centrum Leeuwarden, for patients in Leeuwarden or Harlingen, with appointments, test results, letters, questionnaires and messages. It was due to be replaced on 6 November 2026, but an update on 9 November says the change is taking longer than expected and you can still use mijnMCL for now.
If you are a patient at Medisch Centrum Leeuwarden, known as MCL, MijnMCL can make your care much easier to follow. It puts a useful part of your hospital care in one place, on your computer or phone, so you do not have to wait for a letter or a phone call for every small update. You can check when your next visit is, read a result when it is ready, answer a questionnaire from home, and send a short message to your care team. It does not replace your doctor or nurse, and it is not the right place for urgent help, but for everyday planning and follow up it can save a lot of time and worry. This guide explains what MijnMCL is, who should use it, how to log in and register, what you can do inside it, how to stay safe, and what is changing as it becomes mijnFrisiusMC.
What Is MijnMCL and Who Uses It?
MijnMCL is the secure online patient portal of Medisch Centrum Leeuwarden. In Dutch, a patient portal is a personal, protected website where you can see information from your own medical record and arrange practical things around your care. You log in with your own details, and you see only your own appointments, results, letters and messages.
MCL and Tjongerschans hospital in Heerenveen now work together as Frisius MC. The two hospitals joined on 1 January 2025, but they still used separate patient records and separate portals for a while. That is why the portal you use depends on where you are a patient. If you are a patient in Leeuwarden or Harlingen, you use mijnMCL. If you are a patient in Heerenveen, Joure, Lemmer or Steenwijk, you use mijnTjongerschans.
This matters, because the two systems still work separately. Information in one portal is not automatically copied to the other. If you are a patient at both locations, you may need to check both portals for now, and you will see only the appointments and results for that location in each portal. That can feel confusing at first, so it helps to know which portal belongs to which visit before you log in. The hospital is now moving to one shared electronic patient record and one shared portal, which should remove this split in time.
What You Can Do Inside MijnMCL
MijnMCL is most useful when you use it as your first place to check practical information about your care. The exact options can vary by department, because not every clinic offers every online function yet, but the main things most patients can do are clear and consistent.
You can view your appointments and, for many follow up visits, make a new appointment yourself. You can view the results of tests and examinations that were requested by your hospital team. You can read letters about your appointments and care, often under Messages and then Letters. You can read patient information folders, sometimes called divis, about an examination or treatment, so you can prepare at home. You can fill in questionnaires at home before a visit, which can save time in the clinic and give your care team better information in advance.
You can also send a message to your care team for a question that is not urgent, and you can set SMS reminders for appointments. In the portal you can also see whether a care provider has looked in your record, with the date, the type of care provider and the department, for up to 120 days. That kind of transparency can be reassuring, especially if you want to know who has seen your information and when.
Some appointments are not shown in the portal calendar. This includes appointments for operations or treatments in the operating theatre, appointments at the endoscopy department, and appointments in the heart catheterisation room. For those visits, you will find the information in your invitation letter, which is sent to your home. Most invitation letters can also be found in MijnMCL. When a letter is ready, you usually get an email or SMS from MijnMCL about a week before the planned appointment.
How to Log In to MijnMCL With DigiD
Logging in is designed to be simple once your account is set up, but it is also deliberately secure, because it gives access to sensitive health information. The easiest way for most people in the Netherlands is DigiD.
DigiD is the Dutch government system for proving your identity online. To log in with DigiD, go to mijnMCL.nl or open the MijnMCL app, which is called MyChart, and choose the option to log in with DigiD. Then follow the steps on your screen. You may be asked to confirm with the DigiD app or with an SMS code, depending on how your DigiD is set up.
One condition is important. You can log in with DigiD only if you have been identified at Frisius MC with a valid Dutch identity document and that check has been recorded in your medical record, so your citizen service number, your BSN, has been checked. If that identification has not been done yet, DigiD login may not work. In that case, bring a valid identity document to your next visit and ask for the check to be completed, or use your username and password if you have already registered that way.
If you do not have DigiD yet, you can apply for it through digid.nl or in the DigiD app. If you need help with DigiD itself, your local public library often offers digital walk in sessions and extra support. For questions that are specifically about MijnMCL, the hospital has a digiplein, a digital help desk, and you can email digiplein@frisiusmc.nl.
How to Register for MijnMCL for the First Time
You cannot simply create a MijnMCL account from nothing, because the hospital first needs to be sure that the account belongs to the right patient. That is why registration starts with a registration code.
You will find the code in your appointment letter, or you can ask for it from the assistant of your doctor, at the service desk near the main entrance, or during a hospital admission. Once you have the code, go to mijnMCL.nl and choose the registration option, then follow all the steps to create a username and password. After you are registered, you can also log in with DigiD in future, which many people find quicker.
A registration code is for one time use only, and for safety it expires after 30 days. If your code has expired, or if it has already been used, you will need a new one. You can get a new code during a visit to the clinic, or you can call the department where you received the code and ask them to send a new one by post. The hospital cannot send a new registration code by email, because that would be less secure.
Take a moment to choose a strong password and keep your login details private. Do not share your registration code, username, password or DigiD details with anyone else, even if they offer to help. If someone else needs to help you with your care, ask the hospital about the proper way to authorise them, rather than sharing your login.
Appointments, Test Results and Messages in MijnMCL
Appointments are one of the most used parts of MijnMCL, and it helps to know what the portal can and cannot do. You cannot make your first appointment through MijnMCL. A first appointment is arranged in another way, usually after a referral. You can make follow up appointments through MijnMCL with care providers you have seen in the past year, or with whom you have an appointment in the next three months, if that clinic offers online booking.
If you need to cancel, try to do it at least 24 hours in advance. Some appointments can be cancelled in MijnMCL, and for others you will need to call the department. Cancelling in MijnMCL does not automatically make a new appointment for you. If you still need a visit, call the clinic or make a new appointment through MijnMCL if that option is available for your type of visit.
Sometimes you may receive a new appointment proposal in MijnMCL. This happens when another patient cancels and a place becomes free. You may be offered the chance to move your appointment earlier. You will usually receive this offer together with a few other patients, and the first person to accept it gets the appointment. The offer is visible for only a few hours, so if you do not respond, nothing changes and your current appointment stays as it is. If you do accept, your old appointment is cancelled and the new one appears in your overview.
Test results are another reason many patients open the portal, and it helps to understand the timing. In MijnMCL, your test results are visible four days after the result is known. That delay gives your care team time to review the result first and to contact you if action is needed. If a result is changed later, the updated version can appear in the portal as well. If you have a question about a result, you can ask it during your next conversation with your doctor, or send a question to your care team through MijnMCL.
Messages in the portal are best for questions that can wait until your next visit, or for practical questions about your care. Do not use MijnMCL for an emergency, and do not wait for a portal reply if you feel very unwell or your situation is getting worse quickly. In that case, call the hospital or the emergency services directly. A portal message is useful, but it is not a replacement for urgent care.
MijnMCL, Privacy and Safety: What to Know
Health information is personal, so privacy is a central part of MijnMCL. Only authorised staff who are involved in your care should have access to your medical record, and the hospital records who has looked at it. As noted above, you can check that access history in the portal for up to 120 days, which can help you feel more in control.
You can help protect your own information with a few simple habits. Always log out when you finish, especially if you use a shared computer, a tablet or a phone that other people can use. Do not stay logged in on a public device. Keep your password safe, use a strong and unique password, and never enter your DigiD or portal details on a website you reached through a suspicious link or email. If you receive a message that asks you to log in urgently, go to mijnMCL.nl yourself rather than clicking a link in the message.
MijnMCL is not available in every country. This is because of the risk of digital attacks, and the hospital wants to protect patient data. You can use MijnMCL in the Netherlands and in Belgium, Germany, France, Italy, Spain, Portugal, Greece, Austria, Switzerland and the United Kingdom. If you are travelling outside those countries, you may not be able to log in. If your travel plans change, check your appointments and results before you leave, and ask the clinic what to do if you need help while you are away.
If you want to stop using MijnMCL, or if you need help changing your username or account details, contact the digiplein. You may be asked to show an identity document or to answer questions to confirm who you are, because the hospital must be sure it is changing the record of the right person. Even if you deactivate your account, your medical information stays in your medical record, as the law requires and as your care team needs for safe care.
MijnMCL Is Changing to MijnFrisiusMC: What to Expect
The most important change to know about right now is that MijnMCL is being replaced by one new portal, mijnFrisiusMC. This is part of the move to one shared electronic patient record for Frisius MC in November 2026. After the change, all your medical information for you and your care providers will be in one place, and you will have more options to arrange things yourself at a time that suits you. The hospital also plans to send more information digitally instead of on paper.
The original plan was for MijnMCL to disappear on 6 November and for you to log in to mijnFrisiusMC from that day. The official update on 9 November says the change is taking longer than expected, and until then you can simply keep using MijnMCL. MijnTjongerschans is due to disappear later, on 27 November, when patients in Heerenveen and the surrounding area move to the new portal.
Your care and your appointments do not change because of the new portal. You will log in in the same way, with DigiD or with the username and password you already use for MijnMCL, and you will be able to use the MyChart app with the same login details. Everything you could do in MijnMCL should also be possible in mijnFrisiusMC, with some new options added.
Those new options include test results that are visible as soon as they are known, rather than four days later. You will also be able to view your operations and other procedures under care pathways and operations, view radiology images and images from areas such as nuclear medicine and cardiology, request repeat prescriptions for some medicines, send attachments with messages to your care provider, and authorise someone else to manage your account for you. If you are admitted to hospital, the new portal also has extra functions under my hospital admission, with information about appointments during your stay, medicines and care providers.
One practical change is about appointment confirmations. From 6 November, patients with an account for mijnFrisiusMC will normally no longer receive appointment confirmations by post. You will find the appointment information in the portal, and you will get a notification by email or SMS when a new appointment is made. Some departments may still send letters, because not everything can be shown in the portal yet. If you still want to receive post, you can change this in your settings under Communication preferences and then Appointments, or ask the clinic to do it for you. Because the change was delayed, check the portal for the latest information rather than assuming the old paper routine still applies.
Common MijnMCL Problems and Quick Fixes
Most MijnMCL problems have a simple cause, and a calm check of the basics often solves them. If you cannot log in with DigiD, first check whether your identity and BSN have been checked at the hospital. If not, that is the most likely reason. If you have DigiD but you do not receive an SMS code, check that the hospital has your correct mobile number, and check your SMS messages rather than your email. An SMS code is valid for only a short time, often about 20 minutes, so use the newest code you received. If you copy a code from a message, make sure you do not copy an extra space at the start or end, because that space can make the code invalid.
If your registration code does not work, check whether 30 days have passed since you received it, or whether it has already been used. You will need a new code, which you can get at the clinic or by asking the department to send one by post. If you have forgotten your username or password, use the recovery option on the login page, or contact the digiplein for help. The digiplein is open Monday to Thursday from 9.00 to 16.00 and Friday from 9.00 to 12.30, and you can visit it in the shopping street at Frisius MC Leeuwarden or email digiplein@frisiusmc.nl.
If an appointment is not visible, remember that some types of appointments are not shown in the portal, including operations and some endoscopy and heart catheterisation appointments. Check your invitation letter for those visits. If a test result is not visible yet, remember the four day rule in MijnMCL. If a questionnaire is missing, check whether it was sent for a specific visit or treatment, because not every visit has one. The MyChart app is convenient, but it has slightly fewer options than the MijnMCL website, so if you cannot find a function in the app, try the website on a computer.
If you are still stuck, do not keep trying the same login many times if you are unsure of the details. Contact the digiplein, your clinic, or the hospital main number for Leeuwarden, 058 286 66 66. A short call can often fix a registration or login problem much faster than repeated attempts, and it can prevent your account from being locked for security reasons.
MijnMCL works best when you treat it as a calm, practical helper for your hospital care. Check it before a visit, read the information that is ready for you, fill in what you can at home, and ask a clear question when you need one. Keep your login safe, know the limits of the portal, and remember that the move to mijnFrisiusMC is meant to bring your care together in one place. If you use it in that way, MijnMCL can reduce uncertainty, help you arrive prepared, and give you a clearer view of your own care at Medisch Centrum Leeuwarden.
