The Central Reimbursement Register (CTR)

Updated 04 February 2016

In order to ensure that the pharmacy deducts the right amount of reimbursement from the price of the medicine you buy, the Danish Medicines Agency operates a nationwide electronic register called the Central Reimbursement Register, abbreviated to CTR.

When you buy reimbursable medicine, the pharmacy reports the reimbursement price to the CTR register.

The register keeps your balance updated according to the reimbursement prices reported by the pharmacy. The pharmacy uses your CTR balance to find out how much reimbursement you are to receive when you buy a reimbursable medicine.

Who has access to the CTR register?


All pharmacies in Denmark have access to the information in the CTR register, so it doesn't matter where in Denmark you buy your medicine. You can choose freely among all pharmacies in Denmark.


Your doctor can view your CTR balance via the Medicine Profile.


You can look up your CTR balance yourself via the Medicine Profile. Here you can also see if there are any outstanding amounts, and if you have been granted individual reimbursement.

The Danish Medicines Agency

As owner of the CTR register, the Danish Medicines Agency is obliged to ensure that it works as intended.

How does the CTR register work?

If you receive reimbursement, you become registered in the CTR register. The CTR register records how much money you have spent on reimbursable medicine within a period of one year. It is the size of this amount - also called your balance - which determines the percentage share that the pharmacy is to deduct from the price when you buy medicine.

The reimbursement rates are listed in the table on the page Reimbursement thresholds.

What details are kept in the CTR register?

  • The reimbursement price of every medicine purchase you have made.
  • The total amount of reimbursement granted.
  • Whether you were younger or older than 18 at the beginning of the reimbursement period.
  • The date when you bought reimbursable medicine for the first time, which marked the beginning of your personal one-year reimbursement period.
  • Based on the start date, the CTR determines the end date of your current reimbursement period (reimbursement periods reset after 12 months).
  • Whether you are entitled to reimbursement for the terminally ill.
  • Whether you have been granted single reimbursement
  • Whether you have been granted increased reimbursement. 

How can I view my own details in the CTR register?

  • Against a small fee, the pharmacy can print out a list of your personal details contained in the CTR register. This list is called a transaction list. At the close of your reimbursement period, all details about your medicine purchases in the current period are deleted.
  • The receipt that you receive at the pharmacy displays your balance before purchase.
  • You can access your details in the CTR register via the Medicine Profile, but you need a Digital Signature to access your Medicine Profile, which can be reached via

What is an outstanding amount?

An outstanding amount appears on your balance if you have received either too much or too little reimbursement.

If the amount is positive, you have money in return. This is because you received too little reimbursement in connection with a previous medicine purchase.

If the amount is negative, you must pay money back because you received too much reimbursement in connection with a previous purchase.

The pharmacy must either pay out or collect money, and you are obliged to repay any negative outstanding amounts. You can choose to pay your negative outstanding amount once and for all, but you can also choose to only pay the reimbursement amount that you should otherwise have received the next time you buy medicine. In this way, outstanding amounts are settled as you buy more reimbursable medicine.


You go to the pharmacy to get a particular medicine for which you receive DKK 120 in reimbursement. By looking up the CTR register, the pharmacy sees that you have a negative outstanding amount of DKK 50. Therefore, DKK 50 is deducted from the DKK 120 that you should have received, thus settling your negative balance. This means that you only receive DKK 70 in reimbursement in this particular case.

How do outstanding amounts arise?

A positive outstanding amount could occur, for example, if you have been granted single reimbursement or reimbursement for the terminally ill with retrospective effect. The new grant means that you are entitled to a higher amount of reimbursement than what you received when you bought the medicine before the grant was awarded.

Negative outstanding amounts could occur, for example, if:

  • You switched to a new reimbursement period after the pharmacy calculated the price of your medicine but before your medicine is sent to you or you pay for/collect your medicine. The reason is that some pharmacies wait until they dispense the medicine before they report it to the CTR register.
  • You have not collected the medicine that you ordered from the pharmacy and subsequently buy reimbursable medicine. The reason is that some pharmacies report to the CTR register already when they calculate the price.

The pharmacy can print out a list of transactions made in the CTR register in connection with your medicine purchases. This list also displays how any outstanding amounts have occurred.

What if I don't want to be registered in the CTR register?

If you do not want to be registered in the CTR register, you lose your right to reimbursement from the regions. Tell your pharmacy if you do not want to be registered in CTR, and they will not report any of your purchases.

Who to ask?

If you are unsure that you have received the right amount of reimbursement, you must ask your pharmacy within 12 months from the expiry of the reimbursement period. For this purpose, you should keep your pharmacy receipts for two years.
