Prescription drug price transparency

Sign up for notifications


In 2019, the Washington State Legislature passed Engrossed Second Substitute House Bill into law. This law states requires issuers of health insurance, pharmacy benefit managers (PBMs), manufacturers, and pharmacy service administrative organizations (PSAOs) to submit data to the Health Care Authority (HCA). The purpose is to create an annual report on how prescription drugs affect health care costs. The law also requires pharmaceutical manufacturers to submit data to HCA relating the new drug applications (NDA).


Drug manufacturers, health carriers, pharmacy benefit managers (PBMs), and pharmacy services administrative organizations (PSAOs) are not expected to submit data in 2019. There will not be imposed fines for not submitting in 2019. HCA anticipates being ready to collect data by October 2020.

After completing the bulk of the planning, HCA began notifying data submitters via a series of electronic notifications outlined below.

PBMs are not included in all initial communications as their reporting start date is later.

HCA plans second phase rulemaking under RCW 43.71C

HCA is dedicated to working with reporting entities to ensure successful implementation of a Drug Price Transparency reporting program under RCW 43.71C. We are grateful for all input received thus far and remain committed to collaboration with our stakeholders. 

Accordingly, HCA will be launching a second phase of rulemaking with an anticipated CR-101 filing next week. The rulemaking will:

  • Amend WAC 182-51-0600(2)(b) to clarify that manufacturers must report new covered drugs within 30 days after  release to the market instead of prior  to their release. In the meantime, HCA will not initiate enforcement under RCW 43.71C.090 for manufacturers who do not report the information required by RCW 43.71C.050 prior to the release of a new covered drug to the market. 
  • Amend or create a new rule containing the contents of the nondisclosure agreement.
