Nivelkorvausjärjestelmän

I’m not sure what the full term “Nivelkorvausjä…” refers to. Could you please provide the full word or clarify the context (for example, whether you mean Nivelkorvausjärjestelmä, Nivelkorvaus, or a different concept)? Also, let me know the intended domain (healthcare, insurance, taxation, education, etc.) and whether you want Finnish or another language. Once I have the exact term, I’ll draft a neutral, concise wiki-style article under 300 words.
