# EHR Extraction & Write-back

## Read and write the chart, end to end.

Extract chart, billing, and encounter data from EHR workflows, then push notes, documentation, or structured updates back into the right fields.

**Browser-based, no API required.**

AI can draft the note, summarize the visit, or prepare the chart — but someone still has to open the EHR, find the right patient, copy the output, enter structured fields, and confirm it saved. Asteroid handles that browser work.

## Workflow context

These workflows commonly involve ambulatory EHRs, post-acute EHR systems, hospital and community EHR platforms, enterprise EHR deployments, practice-management systems, and customer clinical workqueues.

## Close the loop inside the EHR.

Asteroid follows the same EHR steps as a trained operator: find the patient, extract the needed chart or billing data, prepare the output, enter notes or structured fields, save the record, and capture confirmation.

### What Asteroid returns

- ✓ Extracted chart data
- ✓ Patient / encounter match
- ✓ Clinical or billing fields captured
- ✓ Note or documentation pushed
- ✓ Structured fields updated
- ✓ Save confirmation
- ✓ Timestamped evidence
- ✓ Exception queue for mismatches or missing data

### Before

- – Open the EHR and search the patient
- – Pull chart, billing, or encounter data
- – Copy AI-generated output into the chart
- – Enter structured fields manually
- – Save and confirm the record
- – Rework exceptions when patient or encounter context is wrong

### After · with Asteroid

- ✓ Submit the task once
- ✓ Chart data is extracted automatically
- ✓ Notes and structured updates are entered
- ✓ Save confirmation is captured
- ✓ Mismatches and missing fields route for review
- ✓ Downstream queues stay updated

## Workflow templates

These reusable workflow templates can be configured around your EHR workflows, note types, chart fields, billing data, patient-matching rules, review process, portal accounts, and output format.

## Frequently asked questions

### We already generate the note or data. What work is still left inside the EHR?

Generating the note isn't filing it. The scribe's output still has to land in the right patient, encounter, and document type inside the EHR, and extraction has the same gap in reverse. Agents write the note into the chart the way a person would and pull authorized fields back out, so neither direction stalls on a system with no usable API.

### Can this run through browser, desktop, or Citrix environments without a new interface?

Yes. Web EHRs run as browser agents; legacy and Citrix-hosted desktop EMRs run as computer-use agents driving the same click-by-click interface a person uses.

### What happens when the patient cannot be matched or the target field is unavailable?

The write doesn't happen. A patient, encounter, or destination that can't be matched above your confidence threshold stops the run and routes to a person with the candidates found.

### What happens when the EHR changes its layout, permissions, or write workflow?

Layout changes are absorbed by reading the screens live (including inside Citrix sessions) rather than replaying coordinates. A permissions change that blocks a write, or an upgrade that restructures the documentation flow, stops runs with the block identified.

### How are PHI, credentials, write permissions, approvals, and audit history handled?

Extraction returns only the field set you authorize; writes run under EHR user accounts you control, scoped to least privilege and revocable at any time.

### What if an EHR or module we need is not in the library?

If a person can operate it through a screen, it's scopeable: map the workflow in the builder against your actual chart-prep or extraction steps, or have Asteroid build and operate it managed.
