For buyers contracting authority
Choose 48814500 when the deliverable is the activity-classification and reimbursement engine, not the systems that feed it. A casemix or DRG grouper takes coded episodes and assigns each a patient group and a cost weight; that is what this code is for. If the contract is really about admissions, transfers and bed management, that is the patient-administration system (48814200), and if it is about the clinical record at the bedside, that is the clinical information system (48814400).
The practical trigger is funding and analysis. Health ministries, regional health authorities and large hospital groups reach for this code when they procure the grouper that drives activity-based payment, hospital benchmarking, and the annual coding refresh. Because the classification logic is revised each year with the national tariff, the same authorities tend to return to this code on a renewal cycle rather than buying once.
One boundary to watch: a casemix grouper is usually bought to plug into a wider hospital information stack. Where a single contract bundles the grouper with the patient-administration layer or with integration work, set the primary CPV code by the dominant purpose, and use 48814500 only when the classification engine is what is actually being procured.
