How the dates on this page work. Manufacturer self-pay prices — NovoCare and LillyDirect — were re-read on the manufacturers’ own published price guides on 4 August 2026. Figures captured from third-party provider websites carry the date we read that provider’s page, which may be earlier; where it is, the row says so. We do not restamp a figure we have not re-read.
