Offline reference for US medical coding — lookups, Ask AI, and your saved work
Legal Documents
Getting Started
Type a term on the Search tab to look up ICD-10-CM and HCPCS Level II codes, descriptors, notes and conventions. The full code library ships inside the app, so keyword search works with no network connection at all and nothing you type into search is transmitted.
Ask takes one chart sentence and returns up to four candidate codes with a confidence band and a one-line rationale. Every result is a draft suggestion, not a coding decision: verify each candidate against the tabular entry, inclusion terms and notes before you submit anything.
Bookmark a code to save it, pin it for quick access from Home, and attach a personal note to record why you kept it. Saved codes, pins and notes live on your device.
Subscription & Purchases
Unlimited keyword search across the bundled code library, plus 10 saved codes, 3 pins and 50 notes. No account and no sign-in are required.
Pro unlocks Ask AI, removes the limits on saved codes, pins and notes, adds the compliance reference views, and enables iCloud sync across your devices. Pro is billed through your Apple Account as a subscription.

Purchases and refunds are handled by Apple, not by this app. Submit the request at reportaproblem.apple.com. Benefits continue until the end of the current billing period after cancellation.
Data & Privacy
In the app sandbox on your device. There are no accounts, no sign-in, no analytics SDK and no crash reporter. The full details are in the Privacy Policy.
No. Subscribing to Pro does not enable it. Sync stays off until you switch it on in Me → iCloud sync, and it moves only your saved codes, pins and notes — through your own iCloud account, never through a server we operate.
Only things you choose to send: a chart sentence submitted to Ask when on-device AI is unavailable (relayed to a cloud model after identifier scrubbing), and a message you type into Me → Feedback & Suggestions.
Keep identifiable patient information out of the app. Ask is not a HIPAA-compliant service, we hold no business associate agreement, and the support mailbox is not configured for PHI. Identifier scrubbing before transmission is best-effort, not a de-identification guarantee.
Troubleshooting
By design. The cloud path requires a device verification step (Apple App Attest) that Mac Catalyst does not support, and on-device reasoning needs Apple Intelligence on iPhone or iPad. Everything else — search, saved codes, pins, notes and iCloud sync — works normally on Mac.
On-device reasoning needs Apple Intelligence switched on and enough free memory. Check iPhone Settings → Apple Intelligence & Siri, and note that Low Power Mode can also gate it off.
Sync requires an active Pro subscription and the switch turned on in Me → iCloud sync. Sign in to the same Apple Account on every device, and make sure iCloud Drive is available. If the device cannot reach iCloud, the app keeps your lists locally and tells you so on that row — nothing is lost.
That is the snapshot date of the code pack built into this app version, not an error. Newer official releases ship with an app update on the annual fiscal-cycle cadence. Always re-verify against the current official tables before billing a claim.
Tap Restore Purchases in the subscription screen, and confirm you are signed in with the same Apple Account used for the purchase. If it still fails, email feedback@17healthy.cn with the app version from Me → About and the receipt date.
