Medical Certificate in Diekirch: Online, Same-Day from €34.99

Diekirch is a northern town close to Ettelbruck, and considerably smaller than the towns further south, but it carries a steady share of requests for certificates in line with its size. The town has its own local employer base of retail, services and small industry, alongside a population that in many cases works or studies further afield and commutes back.

Being smaller and further from the capital does not change what a certificate needs to satisfy — the same national framework, administered via CNS, applies here exactly as it does in Luxembourg City, and a doctor registered to assess cases in Luxembourg reviews cases from Diekirch the same way as from anywhere else in the country.

There's no in-person appointment involved anywhere, including Diekirch: your case is reviewed online by a doctor registered to assess cases in Luxembourg, and where in the country you're based when you request it makes no difference.

For a town of 7,336 people — 21st of the country's 100 communes in 2025 — Diekirch has an unusually institutional employer base sitting alongside its retail and small-industry one. It holds the national operational headquarters of the Luxembourg Army at the Haerebierg Military Centre, one of the six regional headquarters of the Grand Ducal Police, and one of Luxembourg's two judicial districts, plus three secondary schools and a brewery of national importance carrying the town's name. The National Museum of Military History is here too, a legacy of the town's position during the Battle of the Bulge. Uniformed and public-sector employers tend to run their own medical services and their own absence procedures, which is the single most useful thing to know locally before ordering any certificate.

The town sits on the Sauer, and its hospital is not in it: the Centre Hospitalier du Nord runs the north's two sites, on avenue Salentiny in Ettelbruck and in Wiltz, so a hospital trip from Diekirch usually means Ettelbruck a few kilometres down the line. Language works differently here too. Luxembourgish is the national language and French is the sole language of legislation, with Luxembourgish, French and German all used administratively; at the 2021 census, French was used at work by 82.2% of respondents, Luxembourgish by 65.4%, English by 36.7% and German by 29.8%. Telling us which language the person receiving the certificate actually works in is therefore more useful than guessing at a format.

   Reviewed by a doctor registered to assess cases in Luxembourg, generally during business hours (9am-6pm CET/CEST, Monday-Friday).

Typical private consultation costs are a general range reported for Luxembourg and vary by practice and location.

The gap between our pricing and a typical private consultation mostly reflects the difference between booking an in-person appointment slot and completing an online assessment: you're paying for the doctor's review and the certificate itself, not a waiting room or receptionist time.

Luxembourg residents covered by CNS may have some or all of a routine in-person consultation reimbursed through the standard health insurance system; our online assessment is a private, self-pay service and is a different route to obtaining a certificate quickly, rather than a substitute for CNS-linked primary care. If your situation involves an ongoing condition better suited to in-person follow-up, a doctor may advise that route instead.

Prices for every certificate type are shown upfront before you start the assessment, and you are only charged once a doctor has actually reviewed and approved your case, not at the point of submitting your answers. This matters in a market like Luxembourg's, where the cost of an equivalent in-person visit can vary noticeably between a general practice, a specialist, or an occupational health provider, depending on which one you'd otherwise have approached.

Note on employer-specific rules: Notification windows, required internal forms, and whether a copy needs to reach the CNS directly can vary by employer, sector, and the collective agreement that applies to your role. Confirm your own employer's sickness absence policy alongside this general overview, and check current CNS guidance directly if your situation involves a sick-pay matter, as procedures are reviewed periodically.

Every Luxembourg certificate is reviewed by a doctor registered to assess cases in Luxembourg. A clinician will only issue a certificate after genuinely assessing your case, based on the health information you provide and, where needed, follow-up questions asked through the same portal.
