Oystehr v1.33 - November 24, 2025

Terminology Service

• We have added a new Terminology Service to Oystehr! Now you can use Oystehr to search for CPT Codes and HCPCS Codes for use in your applications. See the docs for more information.

Lab Service

• The Oystehr Lab Service now supports client billing.
• We have added the ability to get information about a single Lab service route by ID. Learn more in the API Reference (opens in a new tab).
• Attachments for lab results are now stored in Z3, with a DocumentReference resource created for each attachment. This allows for larger attachment sizes and better management and retrieval of lab result attachments.
  • Note that a specific Z3 bucket needs to be created for this purpose. See the documentation of this feature for more information.
• We've fixed an issue with the "insured's relationship to patient" field on lab orders.
• The route list endpoint is now more reliable, particularly for sandbox projects.
