History
Basis for OPS was the Dutch ICPM-DE, from which the procedure classification OPS-301 according to §301 SGB V was created. Version 1.0 was published in October 1994 and became effective on January 1, 1995. Originally a subset of ICPM, OPS-301 has been expanded by a significant number of national codes since version 2.0 (effective in 2001). The OPS classification gained an enormous importance with the introduction of the G-DRG flat rate system in 2004.
In 2004, the suffix "-301" was omitted, because the application of OPS was no longer limited to the cases regulated by §301 SGB V, being extended to outpatient procedures in hospitals (§115b SGB V) and outpatient care by private physicians (§295 SGB V).
