Build natural-language clinical code finder

[aanishs]

Clinician value

Let a clinician type a plain-language question such as "PHQ-9 total score code" or "taxonomy code for LCSW" and get the most relevant code records with source links.

Scope

• Start with deterministic retrieval over the curated catalog.
• Return code, code system, display text, source, and recommended use context.
• Add examples for LOINC assessment codes, NUCC taxonomy codes, and FHIR Observation snippets.
• Treat user input as non-PHI and show a clear warning not to enter client-identifying details.

Acceptance checks

• Works without an account.
• Handles common abbreviations: PHQ-9, GAD-7, PCL-5, LCSW, LMFT, LPC.
• Returns source-backed records, not free-form invented codes.
• If an LLM layer is added later, it only maps the query to known catalog rows.
