This code system http://fhir.ch/ig/ch-crl/CodeSystem/nkrs-methodfirstdetection defines the following codes:
Code | Display | Definition |
1 | Clinical symptoms | Clinical symptoms related to the tumour. |
2 | Incidental discovery | Diagnosis on the occasion of surveillance/treatment for another disease, incl. tumour aftercare for a previous primary tumour, routine medical consultation/routine check-up, surgery. |

4 | Opportunistic screening | Screening outside an organized or population-based screening programme, as a result of, for example, a recommendation made during a routine medical consultation/check-up for the woman, on the basis of a possibly increased risk for developing cervical cancer or by self-referral. Screening refers to a targeted examination/search for an asymptomatic tumour. |
5 | Self-examination | Use this code if it is known that the chain of events leading to a diagnosis of cancer was a self-exam by the patient (e.g. a lump in the breasts, or a skin lesion). |
6 | Death with autopsy | Cancer diagnosed after death. |
7 | Death without autopsy | Cancer diagnosed after death. |
