# List ICD history

`GET /api/v1/claims/{claim_id}/icd-history`

## Request

- Base URL: `https://developer.claimmind.life` (the document declares no server; this is the origin it was published from)
- URL: `https://developer.claimmind.life/api/v1/claims/{claim_id}/icd-history`
- Auth: none declared. Required headers: `X-API-Key`

List all ICD history records for a claim.

    Returns all versions ordered by version number descending (most recent first).

    Each item carries `origin` — who produced that version: `ai_initial`,
    `ai_revalidate`, `human` or `unknown` (rows written before provenance tagging).
    Treat the set as open: new values may be added. `feedback` is the reason recorded
    with that version, if one was given.

    **Authentication:** API Key (X-API-Key header)
    **Required Scope:** `claims:read`

    **Example Response:**
    ```json
    {
        "items": [
            {
                "id": "...",
                "claim_id": "...",
                "version": 2,
                "icd_inacbg": {"icd9_list": ["01.1"], "icd10_list": ["A01.0", "B02.1"]},
                "icd_idrg": null,
                "created_at": "2026-02-16T11:00:00Z"
            },
            {
                "id": "...",
                "claim_id": "...",
                "version": 1,
                "icd_inacbg": {"icd9_list": ["01.1"], "icd10_list": ["A01.0"]},
                "icd_idrg": {"icd9_list": ["02.2"], "icd10_list": ["C03.0"]},
                "created_at": "2026-02-16T10:00:00Z"
            }
        ],
