Claims count dispensed fills, refills included; a claim is not a prescription written and not a patient count. CMS withholds any prescriber with 10 or fewer claims for a brand row, so a prescriber missing from a list is not confirmed absent and every disclosed count is a floor. Totals and prescriber rows come from two separate CMS files that are not built to reconcile, so a prescriber list never adds up to a published total. Shares are computed only against the totals CMS publishes for the place. Prescriber counts belong to one brand row and are never summed across brands, because one clinician can write several brands. All figures are calendar years.
