OPS

Operationen- und Prozedurenschlüssel. The mandatory procedure classification for inpatient billing in Germany

The German procedure classification, maintained by the BfArM. Required for all inpatient and day-case procedures alongside ICD-10-GM and the basis for DRG-based reimbursement. Around 17,000 codes structured as chapter-group-detail with optional decimal (e.g., 5-470.0). No encounter-type suffix required.
