Hospital Financial Assistance: Reconcile Declared and Documented Income

Install and run

python -m pip install reductoai==0.24.0

For an API-backed run, create manifest.json next to the script and provide the listed documents. Paths resolve from the manifest’s directory:

{
  "application": "documents/application.pdf",
  "evidence": "documents/evidence.pdf"
}

python hospital-financial-assistance-packet.py --manifest manifest.json --output results-01

Use a new output directory for each run. review.json contains the source values, checks, citation map, file hashes, and job references. Findings identify a field or parent record through evidence_paths; use the matching citations and source pages to resolve the issue. The script also saves raw Parse, Extract, and any requested Classify responses.

Configure the workflow for your documents

The string paths above use the baseline settings. A manifest value can also hold a file path plus supported options for that document. Optional --classify checks declared roles before extraction; the Classify criteria should distinguish the actual document types in the packet.

Capture complete schedules across pages

Enable Deep Extract on the role containing a long ledger, payment schedule, or repeated line items. HTML tables preserve merged headers; page markers help diagnose rows crossing a page break. Keep printed row identifiers in the schema and compare extracted counts with the source. Deep Extract increases processing work and cannot recover information missing from Parse. Leave merge_tables off until you confirm that adjacent tables are one continuing schedule.

Replace the evidence entry in manifest.json with this structured entry when the condition above applies. Replace any example page range, sheet name, or prompt with the reviewed selection for your document.

{
  "evidence": {
    "path": "documents/evidence.pdf",
    "parse_config": {
      "formatting": {
        "table_output_format": "html",
        "add_page_markers": true
      }
    },
    "extract_settings": {
      "deep_extract": true
    }
  }
}

Reference: Deep Extract, Table output formats.

Copy the entire script; the two excerpts above use its schemas and helpers.
