PlumCon 2026 is this Thursday, September 3, in San Francisco. The agenda is posted. General registration has closed, but waitlist spots are available.

On August 1 we hosted the YC x Medplum Hackathon at the Y Combinator office in San Francisco, where 160+ hackers built on Medplum in a day. Read the recap.

It was a heavy month of shipping: 198 commits from 22 contributors, with nine patch releases, v5.1.28 through v5.1.36.

DICOM moved to Beta, scheduling got its own React package and a mountable booking workspace — the fastest path yet from empty project to a working calendar. Terminology got its 2026 refresh with multi-language display support, and externally issued JWTs can now authenticate against a specific project rather than the whole server.

All of this continues to drive forward our 2026 roadmap priorities.

We've been hard at work making updates to our Terminology Services to update them for 2026, and are excited to share all the new features and data sets available! The latest UMLS 2026AA data set has been imported into Medplum's hosted environment, and is available for customers to use in their self-hosted clusters as well. In addition, we've made a number of improvements across the core terminology API endpoints to make everything faster and serve multilingual users.

Medical imaging has been the part of the patient record that lives somewhere else. A digital health company builds its charting, ordering, and results workflows on FHIR, and then imaging arrives and the answer is a separate PACS, a separate login, a separate access control model, and a link out to a viewer that knows nothing about the rest of the chart.

Today we are releasing DICOM and DICOMweb support in Beta. A modality on a hospital network can send a study to Medplum over the DICOM network protocol, the study is stored as ordinary Medplum resources under the project's existing access policies, and a DICOMweb viewer can read it back out — with no image server in the middle.

MediMind is a proactive, AI-native hospital system built from the ground up on FHIR R4, now under contract with a 25-hospital network in the Republic of Georgia. Here is why we rebuilt what a hospital runs on instead of adding features to what was already there, and why we built it on Medplum.

Profile Health is building genetic intelligence for longevity and functional medicine — the concierge, naturopathic, and longevity practices that treat chronic, whole-person conditions rather than single episodes of care. Their thesis is simple: the most valuable signal in medicine — a patient's whole genome, enriched with a lifetime of their clinical records — sits scattered, unread, and never makes it into the exam room. Profile fuses the two and hands the result to the physician, so care can get ahead of disease instead of reacting to it.

On Saturday, August 1, 2026, the Y Combinator office in San Francisco filled up with 160+ hackers for the Agentic Healthcare Hackathon, co-hosted by Medplum and Y Combinator.

This post is a celebration of that day, and to express our heartfelt appreciation to every single hacker who showed up and shipped. You are the reason events like this exist, thank you all!

The headline this month: Medplum earned the 2026 FHIRplace Participant emblem from Drummond Group for electronic prior authorization testing, ahead of the January 2027 enforcement date. July was another heavy shipping month — 206 commits from 28 contributors and five patch releases, v5.1.23 through v5.1.27.

On the revenue cycle side, real-time insurance eligibility checks arrived as a FHIR operation of their own, and Claim/$submit learned to route preauthorization requests to their own processor. Elsewhere, server-scoped subscriptions give project-per-tenant deployments one central data-processing flow, a concentrated round of authentication hardening tightened JWT validation, outbound fetch, and MFA, and the Decision Guides are now published natively in the docs. A first DICOMweb implementation also landed in Alpha for teams beginning to work with imaging.

All of this continues to drive forward our 2026 roadmap priorities.

Today is the day: Medplum is hosting the Agentic Healthcare Hackathon with Y Combinator at the YC office in San Francisco on Saturday, August 1, 2026.

Prior authorization is one of the biggest sources of administrative burden in healthcare, and it is now the subject of a regulatory deadline. CMS-0057-F and HTI-4 require payers and providers to support electronic prior authorization workflows built on FHIR, with enforcement beginning January 2027.

Medplum supports ePA transactions for payers AND providers and has earned the 2026 FHIRplace Participant emblem from Drummond Group for our engagement in electronic prior authorization (ePA) testing.

Everself is building the second line of defense for obesity care. Every month, more than a million patients drop off GLP-1 medications, and most regain the weight within three to six months. Until now, the only durable alternative has been invasive bariatric surgery, which can require weeks away from work. Everself fills the gap with an outpatient endoscopic weight loss procedure that delivers bariatric-level results without surgery, wrapped in a longitudinal care program delivered by a full care team.
