The global telehealth market is expected to grow to $101.2B in 2023 and compound at an annual growth rate of 24% til 2030. The introduction of HIPAA-regulated digitized protected health information (PHI) data and patient resources profoundly impacted the industry. This boon created an opportunity for companies to develop patient and provider-facing telemedicine apps that streamline the patient journey and provider care plans.

If you're creating an app to support either of those use cases, leveraging a healthcare API can speed up and take care of the complexities involved in developing your project. The 14 healthcare APIs listed in this article will help you and your engineering team develop key areas of your app that promote interoperability in healthcare settings.

APIs for Patient-Facing Apps

Educated patients have the power to improve and expedite their medical treatment experience. Whether this education supports symptom awareness, disease management comprehension, or the ability to schedule virtual appointments independently, the quicker and more effectively they can communicate with their provider.
