Drug Tariff
NHSBSA produces the Drug Tariff each month on behalf of the Department of Health and Social Care. PharmShop treats tariff values as period-specific reimbursement reference data rather than supplier acquisition prices.
NHS Prescription Services
NHS Prescription Services calculates remuneration and reimbursement due to dispensing contractors across England and publishes guidance for GP practices and other contractors.
Supplier account data
Commercial acquisition prices, availability and supplier basket rules come from connected supplier channels or supplier account evidence. Those values are commercial observations and are stored separately from NHS reimbursement reference data.
Manufacturer and commercial schemes
Where a rebate or manufacturer scheme affects effective procurement cost, PharmShop's aim is to preserve the scheme source, qualifying conditions, effective period and calculation separately rather than silently applying an unexplained adjustment.
Source hierarchy
For medicine identity and NHS reimbursement rules, official NHS sources take precedence over supplier descriptions or third-party summaries. Supplier sources remain authoritative for their own commercial price, availability and account terms.
