For buyers contracting authority
Pick 72212180 when the contract's main job is building clinical or healthcare software to a specification: an electronic patient record, a lab or pathology information system, a clinical scheduling tool, or a bespoke care-management application. The defining test is that working, healthcare-specific software gets built and accepted, not configured from a finished product.
The boundary that trips contracting authorities is the product-versus-build line. Medical software package (48180000) is the right code when a contracting authority is licensing a packaged clinical product, and Medical information systems (48814000) classifies the system itself rather than the development of it. Reserve 72212180 for genuinely bespoke construction, even when some integration or licensing rides alongside.
One step up, the parent 72212100 fits broad sector-specific development that spans more than one vertical or where no single sector dominates. Where a single contract folds a clinical build into a wider hospital IT programme, set the primary CPV code by the dominant deliverable: if writing the healthcare software is the centre of gravity, this code carries it.
