Washington Revised Code Title 18. Businesses and Professions § 18.64.430. Cost disclosure to health care providers

The registered or licensed pharmacist under this chapter shall establish and maintain a procedure for disclosing to physicians and other health care providers with prescriptive authority information detailed by prescriber, of the cost and dispensation of all prescriptive medications prescribed by him or her for his or her patients on request. These charges should be made available on at least a quarterly basis for all requested patients and should include medication, dosage, number dispensed, and the cost of the prescription. Pharmacies may provide this information in a summary form for each prescribing physician for all patients rather than as individually itemized reports. All efforts should be made to utilize the existing computerized records and software to provide this information in the least costly format.
