Azure API for FHIR pricing

Exchange and manage clinical healthcare data through FHIR APIs

“The Azure API for FHIR®” is a Platform-as-a-Service (PaaS) offering allowing organizations to upload, store, manage and analyze healthcare data in the Fast Healthcare Interoperability Resources (FHIR) format. Protected Heal Information (PHI) is protected and rights-managed, data can be analyzed and retrieved using Azure analysis tools, and servers are maintained and backed up by Microsoft. Azure allows practically limitless scalability and access to state-of-the-art machine learning tools.


During the preview period, customers will pay for their Cosmos DB usage resulting from the usage of the service. However, there will be no incremental charge for the managed service during public preview. Pricing for this offering will be announced in future, and customers will be provided with a 30-day notice before we start billing for the service.


  • The Cosmos DB pricing page can be found here.

  • During the preview period, you will not need to select throughput levels for your service. New instances of the Azure API for FHIR will come with default Cosmos DB settings (i.e. 1,000 RUs and single-region write). This is done in order to minimize deployment complexity. Based on usage patterns, we think this should be adequate for dev/test and small POCs. However, if you believe your scenario will have higher performance needs, you can make a request for it by raising a support request. The product team will manually modify the Cosmos DB configuration for an individual instance to either increase performance levels or turn-on multi-region replication, or both (as necessary).

  • Microsoft deploys dedicated Cosmos DB instances to an internal (MSFT) subscription GUID on your behalf. This is necessary to be able to deliver the service to you in a compliant manner.

  • Reservation pricing will not apply to Cosmos DB consumption related to Azure API for FHIR In order to ensure compliance for the service Microsoft will need to host the Cosmos DB instances in an internal Microsoft subscription, which results in reservation prices not being applicable.

  • Yes. Negotiated discounts on Cosmos DB will be applicable.

  • Standard data transfer (egress) charges will apply.
