# Patient Registration: Jurisdiction-Aware Identifiers — User Guide

## What Changed

Patient identifier fields (e.g., "Medicaid Member ID", "State System ID") now display **jurisdiction-specific labels** based on your organization's configured state profile. For Arizona organizations, you'll see "AHCCCS Member ID" and "AHCCCS CIS ID" as before. Organizations in other states will see their state's terminology.

## How It Works

### Registration & Demographics

* **Labels** adapt automatically — no action required.
* **Format hints** appear below identifier fields when your state profile defines a required format (e.g., "Must be 10 digits").
* **Validation** occurs when you leave the field (on blur), not while typing. If the value doesn't match the expected format, you'll see an inline error.

### Patient Detail & List Views

* Identifier columns and detail labels reflect your jurisdiction's terminology.
* When the **alias-first** feature flag is enabled by your administrator, the system displays the generic identifier value (e.g., `Medicaid Member ID`) with automatic fallback to the legacy value if the generic field hasn't been populated yet.

## FAQ

**Q: Do I need to re-enter existing patient identifiers?**\
A: No. Existing data was automatically migrated. Both legacy and generic fields stay in sync via database triggers.

**Q: What if I see the default labels ("Medicaid Member ID") instead of my state's labels?**\
A: Your organization's jurisdiction profile may not be configured yet. Contact your administrator.

**Q: What happens if I enter a value that doesn't match the format hint?**\
A: You'll see a validation error when you leave the field. Correct the value to match the expected format, or clear the field (it's optional).
