Direct answer
The Swedish National Medication List is a live FHIR R4 API. Pin se.electronichealth.fhir.nll.r4 1.3.1 (NLL 21.18). Personnummer uses http://electronichealth.se/identifier/personnummer. NLLMedicationRequest is not a generic MedicationRequest.
Pin the live package, not “Swedish FHIR”
Nationella läkemedelslistan (NLL) is operated by E-hälsomyndigheten (the Swedish eHealth Agency). The external API is FHIR R4. The agency publishes versioned packages on Simplifier and a matching implementation guide. On write day (19 September 2026) the latest public package is:
- Package:
se.electronichealth.fhir.nll.r41.3.1 (created 31 August 2026) - IG: Swedish National Medication List release 21.18
- Canonical claim:
http://electronichealth.se/fhir/ - Guide: simplifier.net/guide/swedishnationalmedicationlist-current
- Handbook: Handbok för vård- och apotekstjänster
Earlier package 1.0.3 is not current. Pin 1.3.1 (or whichever version the buyer’s environment names) in the package lock and re-validate when E-hälsomyndigheten publishes the next sequence.
| NLL profile (IG name) | FHIR resource | What the IG maps | What it is not |
|---|---|---|---|
| NLLPatient | Patient | Patient registered in NLL; personnummer slice identifier:pnr |
Not a national EHR Patient, not an embedded-only identity when pnr exists |
| NLLMedicationRequest | MedicationRequest | A prescription (förskrivning) in NLL | Not a local hospital order, not EU MPD by default |
| NLLMedicationDispense | MedicationDispense | A dispense (uttag) in NLL | Not a ward administration event |
| NLLMedication | Medication | Medicinal product as NLL profiles it | Not an unconstrained Medication resource |
NLL also profiles Provenance, named queries such as latest-dispense, and print/sort code systems. Those are NLL API behaviour, not generic R4 extras you can skip.
The identifier: personnummer
Country-specific identifier on NLLPatient is the Swedish personal identity number (personnummer), slice identifier:pnr:
http://electronichealth.se/identifier/personnummer
Twelve digits, no hyphen (swe-id-rule). Skatteverket assigns it. NLL examples use Skatteverket test identity numbers, not production persons; those test persons are normally absent from NLL test environments. Do not publish a real personnummer. Keep the system URL and a dummy twelve-digit value in fixtures.
When a personnummer is missing, NLLPatient is a contained resource identified by name and birthDate. Do not invent a personnummer to avoid contained Patient.
What to implement first
- If the buyer is connecting to NLL: package
se.electronichealth.fhir.nll.r4#1.3.1(or the version on the target environment), NLLPatient + NLLMedicationRequest + NLLMedicationDispense as the IG maps them, personnummer system as above. - If the buyer wants a Swedish base Patient outside NLL: that is HL7 Sweden Base (
SEBasePatient), a different IG. Do not ship NLL profiles as a national core. - For EHDS ePrescription / eDispensation, NLL is a national medication-list API, not automatically HL7 Europe MPD. Map only when the contract says so.
- Read the handbook for access, headers and search prefixes (
authoredon,whenhandedover). The HL7 FHIR R4 guide does not document NLL search rules.
What this is not
This article is not NLL connection approval, not an E-hälsomyndigheten certificate, not a pharmacy licence, and not legal advice. Implementing NLL profiles in a lab does not authorise production calls. I do not operate NLL test or production access. Personnummer is cited only as an identifier system. Nothing here is clinical or prescribing advice.
