Prescription Types in Germany: Pink, Blue, Green and Yellow

Pink, blue, green, yellow — the colour of a prescription is not a design decision. It tells you who pays and how much time you have. The one most often misunderstood is the green prescription: your health insurance fund pays nothing towards it, and yet it is not a worthless piece of paper. It can save you money on your tax return — and it puts on record that a doctor really did recommend this product to you.

1. Why the type of prescription decides what you pay

A prescription is two things at once: a medical instruction for the pharmacy and a billing document. The second function explains why there are different colours and forms at all. Who bears the cost — your statutory health insurance fund, a private insurer or you yourself — decides which form your practice is allowed to issue.

For you that has three practical consequences. You can see straight away whether a larger sum will be due at the pharmacy. The validity periods differ considerably — with the narcotics prescription you are counting days, not weeks. And some prescriptions you can still use even when nobody is paying for them.

2. The prescription types at a glance

This table answers the three most common questions in one go: what is the prescription for, who pays, and how long do you have to redeem it?^¹

The periods are guide values based on the rules currently in force and can change. If your prescription has been lying around for a while, a half-minute phone call to the pharmacy will settle whether it can still be dispensed.

3. The Kassenrezept: pink paper, today mostly digital

Everyone knows the classic pink form — but as a piece of paper it has become a dying breed. For people with statutory health insurance, prescription-only medicines are now issued as an e-prescription (E-Rezept) as a matter of course: the prescription sits digitally on a server, and you redeem it with your electronic health card, through an app, or with a printed slip carrying a QR code.^²

Nothing changes about the content: same prescription, same rules. In everyday life it does mean that an e-prescription can no longer simply be handed on to a relative if they have neither the card nor the code.

In practice that means prescriptions do not belong in a drawer. Keep your current prescriptions in your medication plan as well, so that at your next appointment you know what is still running.

4. The Privatrezept: blue, but not only for privately insured people

The private prescription is usually blue, sometimes plain white. It is the standard form for every prescription that is not billed to a statutory health insurance fund. That affects more people than you might think:

• Privately insured people and those entitled to Beihilfe: they receive private prescriptions as a matter of course. You pay at the pharmacy yourself first and submit the receipt to your insurer — what comes back depends on your policy.
• People with statutory insurance, for anything outside the catalogue: if a prescription-only product does not fall within the benefits catalogue in your particular case, it is prescribed privately.
• Prescriptions by request: if you specifically want a particular originator product instead of the rebate-contract generic, that only works privately.

Under medicines law a private prescription is normally valid for three months. For reimbursement by your private insurer, separate deadlines apply to submitting the invoice — they are set out in your policy documents.

5. The green prescription: what it can do — and what almost nobody knows

A green prescription carries a product that is not prescription-only — so you could buy it at the pharmacy without any slip of paper at all. Why do you get one, then? Because statutory health insurance does not, as a rule, pay for over-the-counter medicines for adults. The Federal Joint Committee (Gemeinsamer Bundesausschuss, G-BA) draws up a list of exceptions: certain over-the-counter products remain prescribable for certain serious conditions, and more generous rules apply to children.^³ Everything else ends up on green.

Many people therefore throw the green prescription away, or leave it behind at the practice altogether. That is a mistake — for two reasons.

Reason 1: it is your receipt for the tax return

Medical costs you bear yourself can be claimed as extraordinary expenses (außergewöhnliche Belastungen) under § 33 of the German Income Tax Act. Only the share above your individual reasonable personal contribution (zumutbare Belastung) actually has an effect on your tax — and that is calculated from your income, your marital status and the number of children you have.^⁴

What matters is the evidence. For over-the-counter products, tax offices usually require proof that the treatment was medically indicated — and that is exactly what the green prescription provides, together with the pharmacy's till receipt. Without that proof the expense remains a private purchase and is therefore irrelevant for tax.

• Take the green prescription with you — even if you might not buy the product until later.
• Staple the till receipt to it — on request the pharmacy will also issue a receipt showing your name and the preparation.
• Collect them across the year — on its own each receipt looks trivial; added up it often becomes a relevant sum. Whether it works out for you is a question for your tax adviser or an income tax assistance association (Lohnsteuerhilfeverein).

Reason 2: it documents the medical recommendation

The second, often overlooked benefit is a medical one. The green prescription records in writing which preparation at which strength was recommended to you — and by whom. With over-the-counter products that is worth more than it sounds, because preparations with similar names often differ considerably in dose and composition.

Typical candidates for a green prescription are vitamin D and magnesium, along with remedies for cold symptoms, mild digestive problems or dry eyes. These are precisely the products that slip out of view in everyday life — they appear on no official medication plan, even though they can cause interactions. Which is why the green prescription belongs in your medication list too.

6. The yellow BtM-Rezept and the T-Rezept: the special cases

The yellow narcotics prescription (BtM-Rezept) is needed for active substances that fall under the German Narcotics Act: strong opioids for severe pain, certain ADHD medicines such as methylphenidate, individual sleep and substitution medicines. It comes in several parts, is consecutively numbered and is subject to strict documentation requirements — which is why you have only seven days after the date of issue to redeem it.^⁵

The T-Rezept is the rarest case. It applies to a very small number of active substances under a particularly strict safety programme, above all because of severe harm to unborn children. Practice and pharmacy are bound to a fixed procedure, and the window for redeeming it is shorter still at six days.

7. How long is my prescription valid?

The deadlines are the most common stumbling block, because they differ so much. As a rough guide, based on the rules currently in force:

• Kassenrezept: as a rule 28 days as an insurance benefit. After that only if you pay yourself.
• Privatrezept: normally three months.
• BtM-Rezept: seven days after the date of issue.
• T-Rezept: six days after the date of issue.
• Green prescription: no fixed deadline, because nothing is being billed. For tax purposes, though, what counts is the calendar year in which you paid.

Special cases — hospital discharge prescriptions, practice supplies or prescriptions for medical aids — have their own, sometimes considerably shorter, deadlines. Do not rely on rules of thumb from the internet here; ask at the pharmacy directly, where the date is checked before anything is dispensed anyway.

8. Co-payments, exemption and what is left at the end

With statutory prescriptions you pay a statutory co-payment (Zuzahlung) per pack. It sits between a lower and an upper limit and is based on the price of the medicine — so it is not a surcharge for a better preparation. What matters is the annual view: the amounts add up, and there is an annual out-of-pocket limit (Belastungsgrenze). Anyone who exceeds it can be exempted for the rest of the year; more favourable rules apply to people with chronic conditions. The practical mistake here is a banal one — the receipts are not collected, and without them you cannot show that you have reached the limit. How to go about it is set out in the guide Co-payments and exemptions.

9. Aut idem, rebate contracts and the unfamiliar pack

On a statutory prescription there is a small box labelled "aut idem" — Latin for "or the same". It works the opposite way round to intuition: if the box is not ticked, the pharmacy may dispense a preparation with the same active substance. If the practice does tick it, substitution is prohibited and you get exactly the preparation that was prescribed.

Because insurance funds conclude rebate contracts with individual manufacturers, at the pharmacy you often get a different pack from last time: different colour, different company name, same active substance at the same strength. That is intended and as a rule unproblematic, but it unsettles a lot of people — particularly with long-term medication. What lies behind it, and when a switch really can be critical, is explained in Generics vs. brand-name.

10. When your insurance fund will not pay: individual application and appeal

Sometimes you are holding a private or a green prescription although you have statutory insurance and urgently need the product. That is not the end of the road — it just becomes more formal.

1. Ask at the practice why. It makes a difference whether a product is fundamentally not reimbursable or whether all that is missing in your case is a justification.
2. Ask for a medical justification. Your insurance fund needs a medical account: which standard treatments were tried, why did they not work, or why were they not tolerated?
3. Submit the application in writing. An informal letter is usually enough. What matters is that you ask for a decision — information given over the phone is not one.
4. Watch the deadline. If you are turned down, the deadline for appealing is stated in the decision itself. It is binding — note it down straight away.
5. Lodge an appeal. In writing, referring to the decision and with a medical statement attached. Social welfare associations and the independent patient advice service (Unabhängige Patientenberatung) offer support.

The order matters: first the decision, then the purchase. Anyone who pays for a product themselves up front and applies for reimbursement afterwards has a considerably harder time of it. And in the meantime, do not stop anything you are already taking on your own initiative — how to do that safely is set out under Stopping medications.

11. Over-the-counter does not mean harmless

Because a green prescription carries an over-the-counter product, it is easy to get the impression that it cannot do very much — for good or for ill. That is a fallacy. Over-the-counter means that the product is considered safe enough, used as intended and for a limited period, to be supplied without medical supervision. It does not mean that it has no effect and no side effects.^⁶

Three points that are most often underestimated in everyday life:

• Interactions. Over-the-counter products and food supplements influence how other medicines work too. Details under Supplements and medications and Drug interactions.
• Duration. Many over-the-counter products are intended for short-term use. Taking them for weeks means leaving the tested framework — with decongestant nasal sprays that is particularly well known, see Nasal spray dependence.
• Side effects. They occur here too, and are recognised less often because nobody is expecting them. How to spot them is set out under Medication side effects.

For older people, and for anyone taking several preparations, all of that goes double — see Medications in old age and Polypharmacy. The simplest countermeasure costs nothing: tell your practice and your pharmacy about everything you take.
