The Operationen- und Prozedurenschlüssel (OPS) (in 2008, and 2005: OPS-301) is the German modification of the ICPM and now the official classification of operational procedures for power control, the performance record and basis for the claims processing (for inpatient services for G-DRG) of the German hospitals and physicians.
The OPS is now provided on an annual basis by Deutsches Institut für Medizinische Dokumentation und Information.
For coding for DRGs first encryption to the valid version of the ICD-10-GM is (current WHO standard, German Modification) is required. This problem is now often by specially trained clinical coders perceived.
Basis for the OPS, the Dutch ICPM-DE, resulting in the classification key operation according to § 301 SGB V (OPS-301) was formed. OPS-301 Version 1.0 on 14 Published in October 1994 and took effect on 1 January 1995. OPS-301 but was originally only a subset of the ICPM was, but since version 2.0 extends (valid in 2001) a significant number of national codes. An enormous increase in significance was the OPS-classification with the introduction of lump under the DRG system (Diagnosis Related Groups) in 2004.
With version OPS 2005 it accounted for the previously popular suffix "-301", since the application of OPS since that issue is no longer on § 301 SGB V is limited but by out-patient surgery in a hospital (§ 115b SGB V) and the ambulatory care established Doctors (§ 295 SGB V) includes.
