Operation and procedure keys
The Operations and Procedure Code ( OPS ) (as of 2012, until 2005: OPS-301) is the German modification of the International Classification of Procedures in Medicine (ICPM) and today the official classification of operational procedures for performance control, performance verification and the basis for service billing (for inpatient services according to G-DRG ) of German hospitals and resident doctors.
The OPS is now provided annually by the German Institute for Medical Documentation and Information (DIMDI).
For coding according to DRGs, encryption according to the valid version of ICD-10-GM (current WHO standard, German Modification) is required. Today, this task is often performed by specially trained coding specialists .
history
The basis for the OPS was the Dutch ICPM-DE, from which the classification operation key according to §301 SGB V (OPS-301) arose. OPS-301 Version 1.0 was announced on October 14, 1994 and came into effect on January 1, 1995. OPS-301 was originally only a subset of the ICPM, but has been expanded by a considerable number of national codes since version 2.0 (valid in 2001). The importance of the OPS classification increased enormously with the introduction of flat rates per case according to the DRG system ( Diagnosis Related Groups ) in 2004.
With the OPS 2005 version, the previously common suffix “-301” was omitted, since the use of the OPS is no longer restricted to §301 SGB V, but also outpatient operations in the hospital (§115b SGB V) and outpatient care Resident doctors (§295 SGB V) includes.
Features and metrics of the OPS 2008
- mono-hierarchical classification related to physiology
- 6 chapters of procedures, which are not numbered consecutively:
- Chapter 1 - Diagnostic Measures
- Chapter 3 - Diagnostic Imaging
- Chapter 5 - Operations
- Chapter 6 - Medicines
- Chapter 8 - Non-operative therapeutic measures
- Chapter 9 - Complementary Measures
- 65 area headings (e.g. 5-29 to 5-31: Operations on the pharynx, larynx and trachea)
- approx. 230 procedure classes in a three-digit system (e.g. 5-31: other laryngeal operations and operations on the trachea)
- approx. 1400 procedure classes in a four-digit system (e.g. 5-314: excision, resection and destruction (of diseased tissue) of the trachea)
- approx. 7800 procedure classes in the five-digit system (e.g. 5-314.1: resection)
- approx. 18700 additional procedure classes in the six-digit system (e.g. 5-314.11: with end-to-end anastomosis)
- Notation: first three digits numeric, 4th digit alphanumeric, 5th / 6th. Digit numeric or: x - other procedures, y - unspecified
- Topographical structure (no subject area orientation)
- not all digits of the four-digit system used (for comparability with the ICPM)
