What changed in Cortex Lens.

v0.0.61

November 5, 2026

Preparing for release

Help getting signed in

When a chart shows the Cortex sign-in card, we can see it and help you get connected.

• If Lens is waiting for you to sign in, we can see that and reach out sooner. No chart details are sent.
• Nothing changes in how Lens looks or works.

v0.0.60

November 5, 2026

Submitted for Chrome review

Behind-the-scenes privacy work

Lens keeps its record of how reviewed charts change in the same protected place that checks your charts. Nothing changes in how Lens looks or works.

• The before-and-after record Lens keeps for your practice's results report now goes straight to the protected service that checks your charts.
• Includes everything in 0.0.59: the clearer RAF estimate and diagnoses filed under Undefined.

v0.0.59

November 5, 2026

Available

A clearer RAF estimate

The RAF estimate says where its number comes from and shows the conditions it counted.

• A line under the number says it comes from the diagnoses on this chart, using Medicare’s 2026 model.
• Click that line to see each condition counted and the diagnosis codes behind it.
• Lens now reads diagnoses filed under Undefined on the problem list, so they count in every check and in the estimate.

v0.0.58

November 5, 2026

Available

Move Lens out of your way

Drag Lens to any corner so it stays clear of the part of the chart you’re working in.

• Drag Lens by its top bar to any corner. It snaps into place and stays there next time.
• Turn on “Lock Lens position” in settings to keep Lens put. You can still click it to open and close it.

v0.0.57

October 1, 2026

Available

Telehealth visits, clearly labeled

The E/M card recognizes telehealth visits, and Lens controls are easier to see.

• Telehealth and virtual visits show their complexity level with a reminder that the billed code depends on the insurer.
• Buttons and controls in Lens respond when you point at them, so it’s clear what you can click.
• Feedback thumbs are easier to see.
• Signed charts are recognized more reliably, so the addendum reminder appears when it should.

v0.0.56

An easier way to get started

Connect your account from the setup guide and continue to your first chart.

• Setup recognizes Cortex in this browser and helps you finish connecting.
• Read your sign-in code in any inbox, then enter it in the Cortex window.
• Keep your welcome email’s setup link and return whenever you need it.
• Your existing connection stays in place when you revisit setup or update Cortex.

v0.0.55

Available

A guided start with Cortex

Cortex Lens walks you through connecting your account and checking your first chart.

• A setup page opens when you first add Cortex Lens to Chrome.
• Confirm your email and practice before connecting, with clear steps if you need to try again.
• Resume setup from the Lens icon whenever you need it.
• Your feedback stays with your account when you share a computer or change Chrome profiles.

v0.0.54

September 29, 2026

Available

A cleaner RAF estimate panel

The RAF estimate panel is more compact, with clearer wording for potential lift.

• A small info icon opens the calculation details and assumptions.
• Repeated chart and reference labels are removed from the panel.
• Potential lift now reads as an increase, such as "Potential lift +0.84".

v0.0.53

September 29, 2026

Available

Smoother model choice

If you've picked a different AI model in Cortex Lens settings, switching back to Cortex's default now takes one click and re-checks the chart right away.

• "Use Cortex default" clears your choice and re-runs the check in one step.
• Lens keeps showing which model reviewed a chart, even for results it remembers from earlier.
• A model choice that's no longer offered shows up in settings, so you can clear it.
• Behind-the-scenes improvements to how Cortex handles data security. Nothing changes in how Cortex Lens looks or works.

v0.0.51

September 28, 2026

Available

Always on Cortex's best model

Cortex now chooses the AI model on its servers, so every install reviews charts with the current Cortex Engine, today v0.8 running Claude Sonnet 5.5, and future upgrades reach you without an update.

• Cortex Engine v0.8 now reviews your charts: on our benchmark it catches 89% of known coding issues, up from 67%, with no false alarms, and runs about 2.5 times faster.
• The list of models you can pick in settings now comes from Cortex, so new models appear without an update.
• If you've picked a different model, Cortex Lens says so and offers a one-click way back to Cortex's default.

v0.0.49

September 28, 2026

Available

Ready for the newest AI models

Cortex Lens can now run the latest AI models from Anthropic, OpenAI, and Google while our team evaluates them.

• Our team can try newly released models, including Claude Sonnet 5.5, Claude Opus 5.5, GPT-6, and Gemini 3.8 Flash, on the same review Cortex gives your charts.
• See how every model compared on the Cortex benchmarks page.

v0.0.48

July 24, 2026

Available

More reliable extension setup

Cortex Lens now keeps one stable installation record during first-time setup and distinguishes browser updates from new installations.

• Several startup tasks can run at once without creating multiple records for the same browser.
• Browser updates are recorded separately from new installations, giving support a clearer history.
• Cortex records only the browser family, such as Chrome or Brave, never the full browser identifier.

v0.0.47

July 22, 2026

Available

Your charts now show a RAF Estimate

Charts with enough information now show a small RAF Estimate line - the risk score the chart's documentation currently supports, straight from the official CMS model - plus how much higher it could go if Cortex's suggestions belong in the chart.

• One quiet line, like "RAF Estimate 1.14 - Potential lift up to +0.08". It never gets in the way of findings, and charts without enough information simply don't show it.
• The number comes from the official CMS-HCC V28 model for 2026, applied exactly as CMS publishes it - our calculator is tested for exact agreement with CMS's own software.
• Every estimate says what it is: a standardized reference comparison, not a payment amount and not a statement about the patient's insurance.
• "See how we got this number" opens a public methodology page with the full assumptions, limits, and file-level provenance.

v0.0.46

July 22, 2026

A quiet question when Cortex helped

When a code Cortex suggested shows up in the chart, Lens can now ask one small optional question - "Did Cortex lead to this change?" - so your practice's impact numbers reflect what you confirm, not just what we observe.

• One compact row with three buttons: Yes, Already planned, Not related. Answering is always optional, and Dismiss makes it go away for that chart permanently.
• Nothing interrupts your work - no popups, no reminders, no animations.
• Measurement now keeps working through sign-in hiccups: your records queue safely and sync when you're signed back in.
• If your practice has measurement turned on but you're signed out, the extension menu now says so instead of staying silent.

v0.0.45

July 22, 2026

Available

Better before-and-after records

Cortex now keeps a more careful before-and-after record of the charts it checks, so your practice's impact reporting can show real changes instead of estimates. Nothing changes about how you work.

• Cortex remembers what a chart looked like the first time it checked it, and compares later versions - so "what changed after Cortex looked" is answered by the chart itself.
• These records use coded identifiers, never names or chart text, and are covered by your practice's data agreement.
• A small status line in the extension menu shows when this is running for your practice.
• No new buttons, prompts, or steps - your workflow is unchanged.

v0.0.44

July 2, 2026

Available

Cortex notices when you fix things

When a suggested code or medication actually shows up in the chart afterward, Cortex now records that the finding was resolved - powering honest impact reporting for your practice.

• Findings you act on are now remembered: if a suggested code or medication appears in a later look at the same chart, the finding is recorded as fixed - no clicks required.
• Only structured facts are recorded (the code and the finding), never any chart text.
• This feeds your practice's impact summary, so "what did Cortex actually change" is answered by observed chart edits, not guesses.

v0.0.43

July 1, 2026

Available

Small fit and finish

The expand arrow on the checked-categories row no longer gets clipped at the edge of the Lens panel.

• The disclosure arrow on the Checked categories row now sits fully inside the panel instead of being cut off at the right edge.

v0.0.42

July 1, 2026

Available

Claude Sonnet 5 joins the model picker

The newest Claude model - the strongest performer on our public chart-review benchmark - can now be selected for analysis from the extension menu.

• Claude Sonnet 5 is available in the analysis model picker. On our benchmark of de-identified real charts it roughly doubled the previous Sonnet's precision - fewer wrong flags - while catching more real issues.
• The production default is unchanged while the new model is validated; full results and methodology are public at cortexcharts.com/benchmarks.

v0.0.41

July 1, 2026

Available

Privacy provenance, on the record

Every analysis now carries a receipt of the de-identification that ran in your browser before anything left it, and the sign-in prompt explains what signing in is for.

• Each analysis records which de-identification rules ran and how many identifiers they caught - rule names and counts only, never the text itself - so your practice has an auditable privacy trail.
• The extension menu now explains that signing in links your analyses to your practice for impact reporting.
• Under the hood: the public demo site uses its own short-lived access tokens, tightening who can reach the analysis service.

v0.0.40

June 11, 2026

Available

The Lens never moves your page

Hovering the Lens no longer scrolls your chart - the fix for losing your place on dual-screen setups - and settings now speak plainly about the Lens instead of jargon.

• Touching or crossing the Lens panel with your mouse no longer scrolls the chart to a diagnosis row. The matching row still highlights; a new setting lets you turn scroll-on-hover back on if you liked it.
• Both hover behaviors (chart-to-Lens and Lens-to-chart) are now off by default and individually controllable from the extension menu.
• Settings and status text now say Lens or Cortex Lens throughout - no more HUD jargon.

Cortex catches the denials payers love most

Cortex now checks every chart against the official mutually-exclusive-code rules and the unspecified-laterality code list - the two denial classes billers rework most - and knows whether a note is signed when suggesting an E/M level change.

• Problem-list cleanup flags official ICD-10 Excludes1 conflicts (for example I12.9 with I15.0) - the 5,000+ code pairs payers deny whole claims over - with both resolution paths shown so you choose which diagnosis stays.
• It also flags unspecified-side codes (like M25.569, pain in unspecified knee) and lists the exact right/left codes payers will actually pay, so confirming a side takes one look instead of a lookup.
• Both checks surface as warnings, never blocks: ICD-10 allows exceptions, and that judgment stays with you. They run server-side, so they are already live for every installed Lens.
• When a note is already signed, the E/M suggestion now says so - a level change at that point needs a provider addendum, and the Lens is honest about it.
• Three new sandbox patients at cortexcharts.com (Frank Kowalski, Dorothy Eastman, Rosa Delgado) walk through these denial traps end to end.

v0.0.38

Tell Cortex why, calmer reveal behavior

This release lets you explain a thumbs-down right in the panel, stops the Lens from reacting to cursor movement over the chart, and trims visual noise.

• After a thumbs-down, one-tap reason chips and an optional short note appear under the finding, so feedback lands in Cortex instead of a side log.
• Hovering flagged chart rows no longer opens or scrolls the Lens; clicking a flagged row always reveals its card, and hover reveal stays available as an opt-in toggle.
• The checks summary text is smaller and lighter so findings stay the focus.
• Internal Lens layout experiments were consolidated; the panel you see is unchanged unless your practice opts into a variant.

v0.0.37

June 9, 2026

Available

Quiet Lens default polish

This release makes the quieter Lens panel the consistent default and tightens its analysis-scope disclosure during loading.

• Quiet Current is now the default Lens panel in local dev, bundled fallback, and production config unless explicitly overridden.
• The checks summary says Checking while analysis is running and Checked only after the active run settles.
• Lane status chips now live inside the expanded checks disclosure so the main panel has less status clutter.
• The checks disclosure uses the same full-row click and hover behavior as other expandable Lens sections.

v0.0.36

June 9, 2026

Available

Cleaner Lens panel controls

This release tightens the quieter Lens panel candidate and keeps the current production panel available as a fallback.

• The quieter Lens panel has cleaner top controls and less repeated status chrome.
• Changing analysis checks from the Lens panel now targets the extension menu more directly when the browser supports it.
• The current production panel remains available as a fallback while we finish the rollout.
• Additional coverage protects the extension popup bridge used by the cleaner panel.

v0.0.35

June 9, 2026

Available

A quieter Lens panel is ready for testing

This release prepares Cortex Lens for a quieter review panel while keeping the current production view available as a fallback.

• The internal Dev build now opens to the quieter Lens panel so our team can test it against real chart-review workflows.
• The current production panel remains the default for installed users until we intentionally switch it on.
• Hidden findings now have an explicit show-more control, so quieter layouts do not make suggestions inaccessible.
• The panel can safely fall back to the current production layout if a future layout setting is not recognized.

v0.0.34

June 8, 2026

Available

Stronger privacy prep before chart review

Cortex Lens now does more of its chart preparation inside the browser before an analysis starts.

• Chart details are prepared more carefully before they leave the browser for review.
• The privacy pass is better at keeping clinical meaning intact while removing patient identifiers.
• No workflow change is required: open the chart, let Cortex scan, and review suggestions as usual.
• We also tightened the internal Lens Lab views we use to compare future panel designs before pilots see them.

v0.0.30

June 3, 2026

Available

Clearer update prompts and smoother reviews

This update made Cortex Lens easier to keep current and a little quieter during everyday chart review.

• Older browser extensions can now show clearer update guidance before chart analysis gets interrupted.
• Recent feedback choices stay visible after a refresh or quick navigation back to the chart.
• The panel completion state feels more settled when Cortex finishes a review.
• Several admin screens were cleaned up so our team can support pilot practices faster.

v0.0.27

May 29, 2026

Better Practice Fusion reading

Cortex Lens became more comfortable with the different ways Practice Fusion can show encounter notes.

• Read-only encounter pages are recognized more reliably.
• Cortex can use visible notes, diagnoses, and medications when those are the chart details on screen.
• Patient Ledger and other unsupported pages stay quieter until you return to a Summary or Encounter view.
• The extension menu shows adapter health more clearly for support and setup checks.

v0.0.26

One-click feedback and quieter fixes

This release focused on small touches that make suggestions easier to trust and respond to.

• Each suggestion can be marked helpful or not helpful in one click.
• CKD stage checks are less likely to flag documentation that already includes stage 3a or 3b.
• Progress and completion states were tuned to feel conclusive without pulling attention away from the chart.
• Feedback now flows into the review queue we use to improve future releases.
