Curatr

HealthClaw Curatr (healthclaw.io) — patient-facing FHIR data quality evaluation and correction. Use when: (1) Evaluating a patient's health record for coding issues (deprecated code systems, invalid codes, missing required fields), (2) Presenting issues in plain language with clinical impact, (3) Applying patient-approved corrections with full Provenance tracking, (4) Preparing a structured correction request for the patient's healthcare provider. Supports FHIR R4 US Core v9 resources: Condition, AllergyIntolerance, MedicationRequest, Immunization, Procedure, DiagnosticReport — with ICD-10-CM, SNOMED CT, LOINC, CVX, and RxNorm validation via public terminology APIs.

HealthClaw Curatr

A patient-facing data quality skill that evaluates FHIR health records for coding issues, presents them in plain language, and lets the patient decide how to fix them.

Your health data belongs to you. Curatr helps you understand what's in it, spot problems, and take action — whether that's correcting your personal record or requesting your provider fix the source.

Supported FHIR R4 US Core v9 Resource Types

Resource	Checks
Condition	ICD-9 detection, ICD-10-CM/SNOMED validity, clinicalStatus, verificationStatus
AllergyIntolerance	clinicalStatus, patient link, allergen code (RxNorm/SNOMED)
MedicationRequest	status, intent, medication code (RxNorm)
Immunization	status, vaccineCode (CVX/SNOMED), occurrenceDateTime
Procedure	status, procedure code (SNOMED/CPT)
DiagnosticReport	status, report code (LOINC)

For all other resource types, Curatr runs a generic coding scan checking all coding[] elements for deprecated systems.

What Curatr Checks

Code System Quality

Deprecated systems: ICD-9-CM codes (retired October 2015) flagged as critical
Code validity: Live lookups against public terminology services — no account needed
Display name accuracy: Checks whether the written description matches the official term

Structural Completeness

Missing required fields (varies by resource type — see table above)
Invalid status values (e.g. unrecognized clinicalStatus codes)
Missing standard medical codes

Terminology Services Used (all public, no auth required)

Service	Systems Validated
tx.fhir.org — HL7 public FHIR terminology server	SNOMED CT, LOINC
NLM Clinical Tables API	ICD-10-CM
RXNAV API	RxNorm

MCP Tools

`curatr.evaluate` (read-only)

Evaluate a FHIR resource for data quality issues.

Input:

json

{
  "resource_type": "Condition",
  "resource_id": "cond-001"
}

Output: Issues list with plain-language descriptions, impact, and suggestions. Each issue includes severity (critical / warning / info / suggestion), field_path, plain_language, impact, and suggestion.

No step-up required. Safe to call at any time.

`curatr.apply_fix` (write — requires step-up + human confirmation)

Apply patient-approved fixes to a FHIR resource. Creates a linked Provenance record.

Input:

json

{
  "resource_type": "Condition",
  "resource_id": "cond-001",
  "fixes": [
    {
      "field_path": "Condition.code.coding[0].system",
      "new_value": "http://hl7.org/fhir/sid/icd-10-cm"
    },
    {
      "field_path": "Condition.code.coding[0].code",
      "new_value": "E11.9"
    },
    {
      "field_path": "Condition.code.coding[0].display",
      "new_value": "Type 2 diabetes mellitus without complications"
    }
  ],
  "patient_intent": "Updating from retired ICD-9 to ICD-10-CM equivalent"
}

Requires: X-Step-Up-Token header + X-Human-Confirmed: true

Output: Updated resource + linked Provenance resource documenting the change.

Conversation Flow (OpenClaw Messenger)

Always follow this sequence — never apply fixes without patient approval:

text

1. Call curatr.evaluate to get issues
2. For each issue, present:
   - issue.title (bold headline)
   - issue.plain_language (what the problem is, in plain English)
   - issue.impact (why it matters to the patient)
   - issue.suggestion (what to do about it)
3. Ask the patient which fixes they approve
4. Confirm their intent in their own words (used in Provenance)
5. Call curatr.apply_fix with ONLY the approved fixes
6. Confirm completion and show the Provenance record summary

Example Messenger Presentation

text

Curatr found 2 issues in your Diabetes condition record:

─────────────────────────────────────────────────────────
CRITICAL: Outdated code system
Your record uses ICD-9-CM — a code system retired in October 2015.
Most US health systems and insurers no longer accept ICD-9 codes.

Impact: This record may not match your condition when shared with
providers or insurance systems, potentially causing delays.

Suggested fix: Update to ICD-10-CM code E11.9 — "Type 2 diabetes
mellitus without complications"
─────────────────────────────────────────────────────────
INFO: Missing verification status
No indication of whether this diagnosis has been confirmed.

Impact: Without a verification status, AI tools and care summaries
may not know how to weight this condition.

Suggested fix: Add verificationStatus = "confirmed" (or "provisional"
if still being evaluated by your provider)
─────────────────────────────────────────────────────────

What would you like to do?
  [A] Fix both in my personal health record
  [B] Fix the code system only
  [C] Prepare a correction request for my provider
  [D] Keep as-is for now

Severity Levels

Level	Meaning	Example
`critical`	Code system deprecated or structurally broken	ICD-9 code in 2026
`warning`	Code invalid or display name wrong	Invalid clinicalStatus value
`info`	Recommended field missing	No verificationStatus
`suggestion`	A better value exists	Display name differs from canonical

Provenance — What Gets Recorded

Every fix creates a FHIR Provenance resource linked to the updated resource:

Who: "Patient via HealthClaw Curatr"
When: ISO timestamp
What changed: Field-level change summary
Why: Patient's stated intent (verbatim)
Activity code: UPDATE / revise from HL7 v3 DataOperation
Reason code: PATADMIN (patient administration)

The original source record is preserved in the AuditEvent trail. Provenance does not erase history — it adds attribution.

Provider Correction Request

If the patient wants their provider to fix the source record:

Summarize the issues in a human-readable format
Reference the FHIR resource ID and the suggested corrections
Note the public terminology service that flagged the issue
The patient can bring this summary to their provider portal, a patient advocate appointment, or submit via the provider's patient access process

Setup

This skill runs on top of the HealthClaw Guardrails stack. See the fhir-r6-guardrails skill for installation instructions.

bash

# Curatr requires the same stack — no additional services needed
export STEP_UP_SECRET=$(openssl rand -hex 32)
docker-compose up -d --build

# MCP tools available at:
# POST http://localhost:3001/mcp  (Streamable HTTP, preferred)
# GET  http://localhost:3001/sse  (SSE, legacy)

Limitations

Terminology lookups require internet access to tx.fhir.org, NLM, and RXNAV
Live lookups may be skipped if a public service is unavailable (timeouts handled gracefully)
Condition is the primary supported resource type; other resource types receive generic coding scans
Fixes are applied at read time — the original ingested data is unchanged in upstream sources
Provider correction requests are generated as structured summaries only; submission to EHR is out of scope
