Pharmacy Network

Through our partnership with Surescripts, Zus is proud to offer pharmacy-based medication history. This network covers 99% of US pharmacies and 324M+ patients. The service includes a 12 month history of dispensed medications based on paid claims and pharmacy data.

Refresh Frequency

Zus will automatically refresh medication history for your patients

  • Upon initial enrollment
  • Before the appointments that you share with Zus
  • After any 3rd party appointments we pull in from other providers on Carequality and Commonwell.
  • After an ADT discharge
  • 5 days after the expected refill date (as WhenPickedUp + daysSupply) of a previous fill
  • Any time more than 36 days have elapsed between refreshes

Performer, LocationThe pharmacy and physical location where the medication was filled, represented as a reference to both an Organization and a Location resource.

"RF" = Refill
whenPreparedRepresents when the pharmacy filled a given medication
whenPickedUpRepresents when the medication was picked up by the patient

Additionally, raw reference data is stored as a DocumentReference/Binary linked to the patient for builders that prefer to process them on their own.

Missed Pickups

Any fill including a whenPickedUp date can be considered to be picked up by the patient. An empty value does not necessarily indicate a missed pick up, however, as the field is not always populated for fills sourced from claims data. Surescripts indicates claim reversals by simply removing the MedicationDispense from future history results.
